Healthy Weight

Achieving and maintaining a healthy weight includes healthy eating, physical activity, optimal sleep, and stress reduction. Several other factors may also affect weight gain.

Healthy eating features a variety of healthy foods. Fad diets may promise fast results, but such diets limit your nutritional intake, can be unhealthy, and tend to fail in the long run.

How much physical activity you need depends partly on whether you are trying to maintain your weight or lose weight. Walking is often a good way to add more physical activity to your lifestyle.

Managing your weight contributes to good health now and as you age. In contrast, people who have obesity, compared to those with a healthy weight, are at increased risk for many serious diseases and health conditions. See examples of programs that can help.

Helping people maintain a healthy weight is part of CDC’s work to achieve health equity.

Health Equity

In the United States, chronic diseases are leading causes of death and disability, and some groups are affected more than others. For example, obesity is a chronic disease that increases the risk of heart disease, type 2 diabetes, and many types of cancer. The US prevalence of obesity varies by racial and ethnic group, education, age, location, and physical ability.

What Is CDC’s DNPAO Doing?

CDC’s Division of Nutrition, Physical Activity, and Obesity (DNPAO) leads the nation’s public health efforts to promote good nutrition, regular physical activity, and a healthy weight for everyone. These priorities help improve overall health and well-being and prevent, delay, and manage many chronic diseases.

Yet everyone does not have access to affordable, nutritious food and safe places to be physically active. We work with partners and state, tribal, local, and territorial health agencies and organizations to remove environmental and systemic barriers to health. Health equity is when everyone has the opportunity to be as healthy as possible. Our health equity work focuses on three areas:

What Influences Health Equity?

Social Determinants of Health

The conditions in which we are born, live, learn, work, play, worship, and age are  social determinants of health (SDOH). Examples include access to safe and affordable housing, quality education, and quality health care.

Differences in SDOH contribute to persistent chronic disease disparities among racial, ethnic, and socioeconomic groups as well as in different geographies and among people with different physical abilities.

Racism

Racism is a system of structures, policies, practices, and norms that assigns value and determines opportunity because of the way people look or the color of their skin. This results in conditions that unfairly give advantages to some and disadvantages to others. These advantages and disadvantages are passed down through generations.

Racism, both interpersonal and systemic, limits the ability for some groups to build wealth by determining who owns land, buys houses, gets a quality education, and gets living wage jobs. Racism also affects access to quality health care.

Aligned Work

Within the CDC, DNPAO is part of the National Center for Chronic Disease Prevention and Health Promotion. Our work is aligned with the center’s focus on five social determinants of health: built environment, community-clinical linkages, food and nutrition security, social connectedness, and tobacco-free policies.

Along with more than 25 federal agencies, CDC participates in an Interagency Workgroup developing a Long-Term Recovery and Resilience plan [PDF-181KB]. The purpose is toalign federal actions, outline strategies to improve vital conditions, support community and individual recovery from the effects of COVID-19, and positively affect health and well-being over the next 10 years and beyond. Vital conditions are characteristics of places and institutions that communities and individuals need to reach their full potential and serve as the guiding framework for the federal plan. Vital conditions include basic needs for health and safety, life-long learning, a thriving natural world, reliable transportation, humane housing, and a community-centered environment with meaningful work and wealth.

Healthy People 2030, a Department of Health and Human Services project, offers measurable, objectives as well as developmental and research objectives to improve health and well-being. The social determinants of health objectives include economic stability, education access and quality, health care access and quality, neighborhoods that promote health and safety, and increased social and community support

The World Health Organization works to address social determinants of health by compiling and disseminating evidence on what works to address these determinants to help build capacity and advocate for more action.

Diabetes and Your Skin

If you notice any unusual changes in your skin, it’s important to see your doctor. Early diagnosis and treatment are key to preventing serious complications.

Did you know that diabetes can affect many parts of your body, including your skin? In fact, skin changes are one of the most common signs of diabetes. Learn about the signs of diabetes that can appear on your skin.

The skin is the largest organ of the human body. It’s packed with nerves and blood vessels that allow us to sense touch, temperature, pain, and pressure. Diabetes can affect the nerves and blood vessels in your body, including those in your skin. Changes in your skin can be a sign that something is going on beneath the surface.

When diabetes affects your skin, it’s often a sign that your blood sugar levels are too high over time. Some skin changes can appear even before you’ve been diagnosed with diabetes. Others could be a sign that your diabetes treatment needs to be adjusted. Either way, you’ll want to make an appointment with a doctor to be screened for diabetes or to talk about adjusting your treatment. They can help you prevent serious complications with your skin and other parts of your body.

Keep reading to learn about 9 skin conditions that can occur with diabetes and what you can do to treat or prevent them.

1. Acanthosis nigricans (AN)

This skin condition causes a dark patch or band of velvety skin that can appear in body creases such as your neck, armpits, or groin. Sometimes the patches can also appear on your hands, elbows, or knees.

What causes it: AN is a sign of insulin resistance and can be a sign of prediabetes or type 2 diabetes. It is common in people who have obesity.

What to do: Some creams can help make the spots look better, but the most effective treatment is to address the root cause, like obesity or insulin resistance. Lifestyle changes such as being physically active and maintaining a healthy weight can help reverse insulin resistance.

2. Diabetic dermopathy

This condition is also known as shin spots, and it’s harmless. The spots look like red or brown round patches or lines in the skin and are common in people with diabetes. They appear on the front of your legs (your shins) and are often confused with age spots. The spots don’t hurt, itch, or open up.

What causes it: Diabetes can cause changes in small blood vessels that reduce blood supply to the skin.

What to do: This skin condition is harmless and doesn’t need treatment. If you do have any concerns about shin spots, talk to your doctor.

3. Necrobiosis lipoidica

This condition causes yellow, reddish, or brown patches on your skin. It usually begins as small, raised bumps that look like pimples. As it gets worse, the bumps turn into patches of swollen, hard skin. This skin condition is rare, but if it does develop it can be itchy and painful.

What causes it: The cause of necrobiosis lipoidica isn’t completely clear, but women are more likely to have it than men. It usually develops when changes in fat and collagen (a fiber-like protein in your body) happen beneath the skin’s surface.

What to do: There is no cure for the condition, so treatment is focused on managing signs and symptoms. In the early stages, topical steroid creams can be used to keep it from getting worse. You’ll want to talk with your doctor so they can find the right treatment plan for you.

4. Bullosis diabeticorum (diabetic blisters)

This condition looks like burn blisters. They can develop on your lower legs and feet, and sometimes on your arms and hands. They can look scary, but they are painless and usually heal on their own.

What causes it:  The cause of diabetic blisters is unknown. They can appear with no known injury to the skin. You’re more likely to get diabetic blisters if your blood sugars levels are high over time.

What to do: Most blisters heal on their own without leaving a scar. Daily inspection of your feet and skin is the best way to find early signs of blisters. The best way to prevent them from developing or getting worse is to bring your blood sugar down to normal levels.

5. Eruptive xanthomatosis

This condition causes small, reddish-yellow bumps on the back of your hands, feet, arms, legs, and buttocks. They can be tender and itchy.

What causes it: This condition is rare. It’s caused by having high levels of cholesterol and triglycerides (fat in the blood).

What to do: The best treatment is to bring blood fat levels under control. Your doctor may also want to prescribe medicine to help lower your cholesterol. Talk to your doctor about having your cholesterol checked so that you can take steps to prevent high cholesterol.

6. Digital sclerosis

This condition starts with tight, thick, waxy skin on your fingers and can cause your finger joints to become stiff and hard to move. If blood sugar levels remain high, digital sclerosis can cause your skin to become hard, thick, and swollen and can spread throughout your body.

What causes it: This condition is more common in people with type 1 diabetes who have high blood sugar levels.

What to do: The only treatment for digital sclerosis is to bring blood sugar levels down into the normal range. Physical therapy may help improve the range of motion of affected joints.

7. Bacterial infections

Bacterial infections cause tissue (cells that make up organs and other body parts) to become inflamed, hot, swollen, red, and painful. Common bacterial infections include those on the eyelids, hair follicles, and fingernails.

What causes it: Anyone can get a bacterial infection, but people with diabetes tend to get more than people without diabetes. Bacteria thrive when there is too much glucose (sugar) in the body. A common type of bacteria responsible for bacterial infections in people with diabetes is staphylococcus (staph).

What to do: Bacterial infections usually can be treated with antibiotics. Keeping your blood sugar levels within the normal range can help you avoid infections. Healthy eating, getting physical activity, and taking your medicine as instructed can help you manage your blood sugar.

8. Fungal infections

Fungal infections create itchy rashes surrounded by tiny red blisters and scales. They usually develop in warm, moist folds of the skin. Common fungal infections include jock itch, athlete’s foot, ringworm, and vaginal infections.

What causes it: Like bacterial infections, anyone can get a fungal infection, but they are common in people with diabetes. Fungal infections are more likely to occur when blood sugar levels are high.

What to do: Talk to your doctor about prescription or over-the-counter medicine that can help treat fungal infections. Keeping blood sugar levels within the normal range by checking your blood sugar often, eating healthy, and getting regular exercise is the best way to prevent fungal infections.

9. Dry, itchy skin

This skin condition is common, even for people who don’t have diabetes. But dry, itchy skin can be a result of poor circulation, which is more likely when you have diabetes.

What causes it: Too much sugar in the blood causes the body to pull fluid from its cells so that it can produce enough urine to remove the excess sugar. This can make your skin dry.

What to do: You’ll want to monitor your blood sugar levels and keep them in your target range as much as possible. It also helps if you limit your time in the shower, use mild soaps, and use lotion after showering. Exercise is one of the best ways to improve circulation—and has many other health benefits.

Be Good to Your Skin

Skin is a good indicator of health. If you notice any unusual changes in your skin, it’s important to see your doctor. Early diagnosis and treatment are key to preventing serious complications from skin problems caused by diabetes.

What is Monkeypox?

Monkeypox is a rare disease caused by infection with the monkeypox virus. Monkeypox virus belongs to the Orthopoxvirus genus in the family Poxviridae. The Orthopoxvirus genus also includes variola virus (which causes smallpox), vaccinia virus (used in the smallpox vaccine), and cowpox virus. Monkeypox is not related to chickenpox.

Monkeypox was first discovered in 1958 when two outbreaks of a pox-like disease occurred in colonies of monkeys kept for research. Despite being named “monkeypox”, the source of the disease remains unknown. However, African rodents and non-human primates (like monkeys) may harbor the virus and infect people.

The first human case of monkeypox was recorded in 1970. Since then, monkeypox has been reported in people in several other central and western African countries. Prior to the 2022 outbreak, nearly all monkeypox cases in people outside of Africa were linked to international travel to countries where the disease commonly occurs, or through imported animals.

Sign & Symptoms: 

Monkeypox is a rare disease caused by infection with the monkeypox virus. Monkeypox virus is part of the same family of viruses as smallpox. Monkeypox symptoms are similar to smallpox symptoms, but milder; and monkeypox is rarely fatal. Monkeypox is not related to chickenpox.

Symptoms of monkeypox can include:

  • Fever
  • Headache
  • Muscle aches and backache
  • Swollen lymph nodes
  • Chills
  • Exhaustion
  • A rash that can look like pimples or blisters that appears on the face, inside the mouth, and on other parts of the body, like the hands, feet, chest, genitals, or anus.
    • The rash goes through different stages before healing completely. The illness typically lasts 2-4 weeks.

Sometimes, people get a rash first, followed by other symptoms. Others only experience a rash.

Prevention:

There are number of measures that can be taken to prevent infection with monkeypox virus:

  • Avoid contact with animals that could harbor the virus (including animals that are sick or that have been found dead in areas where monkeypox occurs).
  • Avoid contact with any materials, such as bedding, that has been in contact with a sick animal.
  • Isolate infected patients from others who could be at risk for infection.
  • Practice good hand hygiene after contact with infected animals or humans. For example, washing your hands with soap and water or using an alcohol-based hand sanitizer.
  • Use personal protective equipment (PPE) when caring for patients.

Practice good hand hygiene after contact with infected animals or humans.

JYNNEOSTM  (also known as Imvamune or Imvanex) is an attenuated live virus vaccine which has been approved by the U.S. Food and Drug Administration for the prevention of monkeypox. On November 3, 2021, the Advisory Committee on Immunization Practices (ACIP) voted to recommend JYNNEOS pre-exposure prophylaxis as an alternative to ACAM2000 for certain persons at risk for exposure to orthopoxviruses.

Diarrhea and Swimming

You can get sick with diarrhea if you swallow contaminated recreational water—water in pools, hot tubs, water playgrounds, or oceans, lakes, and rivers. In fact, diarrhea is the most common illness reported for outbreaks linked to recreational water.

Which germs in recreational water cause diarrhea?

You can get diarrhea from germs such as

These germs can survive in properly chlorinated water for minutes to days, depending on the germ.

How do germs that cause diarrhea spread in recreational water?

If someone is sick and has diarrhea in the water, millions of germs can contaminate the water. These germs can make other people sick if they swallow even a small amount of contaminated water. Swallowing 10 or fewer germs can make people sick. Germs can also get in the water if swimmers have poop, even tiny amounts, on their bottoms.

Pool chemicals and filters help kill germs

Filters and disinfectants (chemicals that disinfect the water, such as chlorine or bromine) work together to help kill germs in pools, hot tubs, and water playgrounds. Filters remove debris (such as leaves), which use up the disinfectant in the water. Pool staff make sure chlorine or bromine is at the level needed to kill most germs in the water within minutes. You can still be exposed to germs during the time it takes for the water to go through filters and for the disinfectant to kill germs. You can also get diarrhea from germs that are hard to kill, such as Crypto. Crypto stays alive for more than 7 days, even if water is properly filtered and disinfected.

Many places with pools use one filtration system for more than one pool, which causes water from multiple pools to mix. This means germs from one person’s body could contaminate the water in more than one pool.

How do I protect myself and those I care about?

We all share the water we swim, play, or relax in. Each of us can help protect ourselves, our families, and our friends from germs that can cause diarrhea.

Take the following steps when swimming in any type of water:

  • Stay out of the water if you are sick with diarrhea.
    • If you have Crypto, don’t go in the water until 2 weeks after diarrhea has completely stopped.
  • Don’t poop in the water.
  • Don’t swallow the water.
  • Take kids on bathroom breaks and check diapers every hour.
    • Change diapers away from the water’s edge to keep germs from getting in the water. Wash your hands after.

Before going in pools, water playgrounds, and hot tubs, also take these steps:

  • Use test strips to make sure the water has proper free chlorine (amount of chlorine available to kill germs) or bromine level and pH.
    • Free chlorine level: at least 1 part per million (ppm) in pools and water playgrounds and at least 3 ppm in hot tubs
    • Bromine level: at least 3 ppm in pools and water playgrounds and at least 4 ppm in hot tubs
    • pH (affects how well chlorine and bromine can kill germs): 7.2–7.8
    • Most superstores, hardware stores, and pool supply stores sell test strips. Follow the directions on the test strip package.
  • Shower before you get in the water.
    • A 1-minute shower removes most of the dirt, sweat, and oils on your body that use up chlorine or bromine needed to kill germs.

Follow these and other healthy swimming steps to help protect you and those you care about from getting sick.

Loneliness and Social Isolation Linked to Serious Health Conditions

Social isolation was associated with about a 50% increased risk of dementia and other serious medical conditions.

Loneliness and social isolation in older adults are serious public health risks affecting a significant number of people in the United States and putting them at risk for dementia and other serious medical conditions.

A report from the National Academies of Sciences, Engineering, and Medicine (NASEM) points out that more than one-third of adults aged 45 and older feel lonely, and nearly one-fourth of adults aged 65 and older are considered to be socially isolated.1 Older adults are at increased risk for loneliness and social isolation because they are more likely to face factors such as living alone, the loss of family or friends, chronic illness, and hearing loss.

Loneliness is the feeling of being alone, regardless of the amount of social contact. Social isolation is a lack of social connections. Social isolation can lead to loneliness in some people, while others can feel lonely without being socially isolated.

Health Risks of Loneliness

Although it’s hard to measure social isolation and loneliness precisely, there is strong evidence that many adults aged 50 and older are socially isolated or lonely in ways that put their health at risk. Recent studies found that:

  • Social isolation significantly increased a person’s risk of premature death from all causes, a risk that may rival those of smoking, obesity, and physical inactivity.1
  • Social isolation was associated with about a 50% percent increased risk of dementia.1
  • Poor social relationships (characterized by social isolation or loneliness) was associated with a 29% increased risk of heart disease and a 32% increased risk of stroke.1
  • Loneliness was associated with higher rates of depression, anxiety, and suicide.
  • Loneliness among heart failure patients was associated with a nearly 4 times increased risk of death, 68% increased risk of hospitalization, and 57% increased risk of emergency department visits.

Immigrant, LGBT People Are at Higher Risk

The report highlights loneliness among vulnerable older adults, including immigrants; lesbian, gay, bisexual, and transgender (LGBT) populations; minorities; and victims of elder abuse. It also points out that the literature base for these populations is sparse and more research is needed to determine risks, impacts, and appropriate actions needed.

Current research suggests that immigrant, and lesbian, gay, bisexual populations experience loneliness more often than other groups. Latino immigrants, for example, “have fewer social ties and lower levels of social integration than US-born Latinos.” First-generation immigrants experience stressors that can increase their social isolation, such as language barriers, differences in community, family dynamics, and new relationships that lack depth or history, the report states. Similarly, gay, lesbian, and bisexual populations tend to have more loneliness than their heterosexual peers because of stigma, discrimination, and barriers to care.

What Can You Do If You Are Experiencing Loneliness?

Your doctor can assess your risk for loneliness and social isolation and get you connected to community resources for help, if needed. The following national organizations also offer helpful resources:

AARP—Provides helpful information to seniors to help improve quality of life and provides access to Community Connection Tools.

Area Agencies on Aging (AAA)—A network of over 620 organizations across America that provides information and assistance with programs including nutrition and meal programs (counseling and home-delivered or group meals), caregiver support, and more. The website can help you find your local AAA, which may provide classes in Tai Chi and diabetes self-management.

Eldercare Locator—A free national service that helps find local resources for seniors such as financial support, caregiving services, and transportation. It includes a brochure that shows how volunteering can help keep you socially connected.

National Council on Aging—Works with nonprofit organizations, governments, and businesses to provide community programs and services. This is the place to find what senior programs are available to assist with healthy aging and financial security, including the Aging Mastery Program® that is shown to increase social connectedness and healthy eating habits.

National Institute on Aging (NIA)– Provides materials on social isolation and loneliness for older adults, caregivers, and health care providers. Materials include health information, a print publication available to view or order no-cost paper copies, a health care provider flyer, and social media graphics and posts.

Health Care System Interventions Are Key

People generally are social by nature, and high-quality social relationships can help them live longer, healthier lives. Health care systems are an important, yet underused, partner in identifying loneliness and preventing medical conditions associated with loneliness.

Nearly all adults aged 50 or older interact with the health care system in some way. For those without social connections, a doctor’s appointment or visit from a home health nurse may be one of the few face-to-face encounters they have. This represents a unique opportunity for clinicians to identify people at risk for loneliness or social isolation.

NASEM recommends that clinicians periodically assess patients who may be at risk and connect them to community resources for help. In clinical settings, NASEM recommends using the Berkman-Syme Social Network Index (for measuring social isolation) and the three-item UCLA Loneliness Scale (for measuring loneliness).

But patients must make their own decisions. Some people may like being alone. It is also important to note that social isolation and loneliness are two distinct aspects of social relationships, and they are not significantly linked. Both can put health at risk, however.

Manage Blood Sugar

It’s important to keep your blood sugar levels in your target range as much as possible to help prevent or delay long-term, serious health problems, such as heart disease, vision loss, and kidney disease. Staying in your target range can also help improve your energy and mood. Find answers below to common questions about blood sugar for people with diabetes.

Use a blood sugar meter (also called a glucometer) or a continuous glucose monitor (CGM) to check your blood sugar. A blood sugar meter measures the amount of sugar in a small sample of blood, usually from your fingertip. A CGM uses a sensor inserted under the skin to measure your blood sugar every few minutes. If you use a CGM, you’ll still need to test daily with a blood sugar meter to make sure your CGM readings are accurate.

When should I check my blood sugar?

How often you check your blood sugar depends on the type of diabetes you have and if you take any diabetes medicines.

Typical times to check your blood sugar include:

  • When you first wake up, before you eat or drink anything.
  • Before a meal.
  • Two hours after a meal.
  • At bedtime.

If you have type 1 diabetes, have type 2 diabetes and take insulin, or often have low blood sugar, your doctor may want you to check your blood sugar more often, such as before and after you’re physically active.

What are blood sugar targets?

A blood sugar target is the range you try to reach as much as possible. These are typical targets:

  • Before a meal: 80 to 130 mg/dL.
  • Two hours after the start of a meal: Less than 180 mg/dL.

Your blood sugar targets may be different depending on your age, any additional health problems you have, and other factors. Be sure to talk to your health care team about which targets are best for you.

What causes low blood sugar?

Low blood sugar (also called hypoglycemia) has many causes, including missing a meal, taking too much insulin, taking other diabetes medicines, exercising more than normal, and drinking alcohol. Blood sugar below 70 mg/dL is considered low.

Signs of low blood sugar are different for everyone. Common symptoms include:

  • Shaking.
  • Sweating.
  • Nervousness or anxiety.
  • Irritability or confusion.
  • Dizziness.
  • Hunger.

Know what your individual symptoms are so you can catch low blood sugar early and treat it. If you think you may have low blood sugar, check it even if you don’t have symptoms. Low blood sugar can be dangerous and should be treated as soon as possible.

How can I treat low blood sugar?

If you’ve had low blood sugar without feeling or noticing symptoms (hypoglycemia unawareness), you may need to check your blood sugar more often to see if it’s low and treat it. Driving with low blood sugar can be dangerous, so be sure to check your blood sugar before you get behind the wheel.

Carry supplies for treating low blood sugar with you. If you feel shaky, sweaty, or very hungry or have other symptoms, check your blood sugar. Even if you don’t have symptoms but think you may have low blood sugar, check it. If your blood sugar is lower than 70 mg/dL, do one of the following immediately:

  • Take four glucose tablets.
  • Drink four ounces of fruit juice.
  • Drink four ounces of regular soda, not diet soda.
  • Eat four pieces of hard candy.

Wait for 15 minutes and then check your blood sugar again. Do one of the above treatments again until your blood sugar is 70 mg/dL or above and eat a snack if your next meal is an hour or more away. If you have problems with low blood sugar, ask your doctor if your treatment plan needs to be changed.

What causes blood sugar to be high?

Many things can cause high blood sugar (hyperglycemia), including being sick, being stressed, eating more than planned, and not giving yourself enough insulin. Over time, high blood sugar can lead to long-term, serious health problems. Symptoms of high blood sugar include:

  • Feeling very tired.
  • Feeing thirsty.
  • Having blurry vision.
  • Needing to urinate (pee) more often.

If you get sick, your blood sugar can be hard to manage. You may not be able to eat or drink as much as usual, which can affect blood sugar levels. If you’re ill and your blood sugar is 240 mg/dL or above, use an over-the-counter ketone test kit to check your urine for ketones and call your doctor if your ketones are high. High ketones can be an early sign of diabetic ketoacidosis, which is a medical emergency and needs to be treated immediately.

What are ketones?

Ketones are a kind of fuel produced when fat is broken down for energy. Your liver starts breaking down fat when there’s not enough insulin in your bloodstream to let blood sugar into your cells.

What is diabetic ketoacidosis?

If you think you may have low blood sugar, check it even if you don’t have symptoms.

When too many ketones are produced too fast, they can build up in your body and cause diabetic ketoacidosis, or DKA. DKA is very serious and can cause a coma or even death. Common symptoms of DKA include:

  • Fast, deep breathing.
  • Dry skin and mouth.
  • Flushed face.
  • Frequent urination or thirst that lasts for a day or more.
  • Fruity-smelling breath.
  • Headache.
  • Muscle stiffness or aches.
  • Nausea and vomiting.
  • Stomach pain.

If you think you may have DKA, test your urine for ketones. Follow the test kit directions, checking the color of the test strip against the color chart in the kit to see your ketone level. If your ketones are high, call your health care provider right away. DKA requires treatment in a hospital.

DKA happens most in people with type 1 diabetes and is sometimes the first sign of type 1 in people who haven’t yet been diagnosed. People with type 2 diabetes can also develop DKA, but it’s less common.

How can I treat high blood sugar?

Talk to your doctor about how to keep your blood sugar levels within your target range. Your doctor may suggest the following:

  • Be more active. Regular exercise can help keep your blood sugar levels on track. Important: don’t exercise if ketones are present in your urine. This can make your blood sugar go even higher.
  • Take medicine as instructed. If your blood sugar is often high, your doctor may change how much medicine you take or when you take it.
  • Follow your diabetes meal plan. Ask your doctor or dietitian for help if you’re having trouble sticking to it.
  • Check your blood sugar as directed by your doctor. Check more often if you’re sick or if you’re concerned about high or low blood sugar.
  • Talk to your doctor about adjusting how much insulin you take and what types of insulin (such as short-acting) to use.

How do carbs affect blood sugar?

Carbs in food make your blood sugar levels go higher after you eat them than when you eat proteins or fats. You can still eat carbs if you have diabetes. The amount you can have and stay in your target blood sugar range depends on your age, weight, activity level, and other factors. Counting carbs in foods and drinks is an important tool for managing blood sugar levels. Make sure to talk to your health care team about the best carb goals for you.

What is the A1C test?

The A1C test  is a simple blood test that measures your average blood sugar levels over the past 2 or 3 months. The test is done at a lab or your doctor’s office in addition to—not instead of—regular blood sugar testing you do yourself.

A1C testing is part of the ABCs of diabetes—important steps you can take to prevent or delay health complications down the road:

  • A: Get a regular A1C test.
  • B: Try to keep your blood pressure below 140/90 mm Hg (or the target your doctor sets).
  • C: Manage your cholesterol levels.
  • s: Stop smoking or don’t start.

The A1C goal for most adults with diabetes is between 7% and 8%, but your goal may be different depending on your age, other health conditions, medicines you’re taking, and other factors. Work with your doctor to establish a personal A1C goal for you.

What else can I do to help manage my blood sugar levels?

Eating a healthy diet with plenty of fruit and vegetables, maintaining a healthy weight, and getting regular physical activity can all help. Other tips include:

  • Keep track of your blood sugar levels to see what makes them go up or down.
  • Eat at regular times, and don’t skip meals.
  • Choose foods lower in calories, saturated fat, trans fat, sugar, and salt.
  • Track your food, drink, and physical activity.
  • Drink water instead of juice or soda.
  • Limit alcoholic drinks.
  • For a sweet treat, choose fruit.
  • Control your food portions (for example, use the plate method: fill half your plate with non-starchy vegetables, a quarter with lean protein, and a quarter with a grain or starchy food).

How can I pay for tests and diabetes supplies?

Medicare, Medicaid, and most private insurance plans pay for the A1C test and fasting blood sugar test as well as some diabetes supplies. Check your plan or ask your health care team for help finding low-cost or free supplies, and see How to Save Money on Diabetes Care for more resources.

Planning for Pregnancy

If you are trying to have a baby or are just thinking about it, it is not too early to start getting ready for pregnancy. Preconception health and health care focus on things you can do before and between pregnancies to increase the chances of having a healthy baby. For some women, getting their body ready for pregnancy takes a few months. For other women, it might take longer. Whether this is your first, second, or sixth baby, the following are important steps to help you get ready for the healthiest pregnancy possible.

1. Make a Plan and Take Action

Whether or not you’ve written them down, you’ve probably thought about your goals for having or not having children, and how to achieve those goals. For example, when you didn’t want to have a baby, you used effective birth control methods to achieve your goals. Now that you’re thinking about getting pregnant, it’s really important to take steps to achieve your goal [PDF – 764 KB]—getting pregnant and having a healthy baby!

Preventive health care can help you stay healthier throughout your life.

2. See Your Doctor

Before getting pregnant, talk to your doctor about preconception health care. Your doctor will want to discuss your health history and any medical conditions you currently have that could affect a pregnancy. He or she also will discuss any previous pregnancy problems, medicines that you currently are taking, vaccinations that you might need, and steps you can take before pregnancy to prevent certain birth defects.

If your doctor has not talked with you about this type of care―ask about it! Take a list of talking points so you don’t forget anything!

Be sure to talk to your doctor about:

Medical Conditions

If you currently have any medical conditions, be sure they are under control and being treated. Some of these conditions include: sexually transmitted diseases (STDs), diabetes, thyroid disease, high blood pressure, and other chronic diseases.

Lifestyle and Behaviors

Talk with your doctor or another health professional if you smoke, drink alcohol, or use certain drugs; live in a stressful or abusive environment; or work with or live around toxic substances. Health care professionals can help you with counseling, treatment, and other support services.

Medications

Taking certain medicines during pregnancy can cause serious birth defects. These include some prescription and over-the-counter medications and dietary or herbal supplements. If you are planning a pregnancy, you should discuss the need for any medication with your doctor before becoming pregnant and make sure you are taking only those medications that are necessary.

People may use opioids as prescribed, may misuse prescription opioids, may use illicit opioids such as heroin, or may use opioids as part of medication-assisted treatment for opioid use disorder. If a woman is pregnant or planning to become pregnant, the first thing she should do is talk to a healthcare provider. Some women need to take an opioid medication during pregnancy to manage pain or to treat opioid use disorder. Creating a treatment plan for opioid use disorder, as well as other co-occurring health conditions, before pregnancy can help a woman increase her chances of a healthy pregnancy. If you are struggling with an opioid use disorder, take a look at CDC’s and partner resources.

Vaccinations (shots)

Some vaccinations are recommended before you become pregnant, during pregnancy, or right after delivery. Having the right vaccinations at the right time can help keep you healthy and help keep your baby from getting very sick or having lifelong health problems.

3. Take 400 Micrograms of Folic Acid Every Day

Folic acid is a B vitamin. If a woman has enough folic acid in her body at least 1 month before and during pregnancy, it can help prevent major birth defects of the baby’s brain and spine.

6. Reach and Maintain a Healthy Weight

People who are overweight or obese have a higher risk for many serious conditions, including complications during pregnancy, heart disease, type 2 diabetes, and certain cancers (endometrial, breast, and colon).1 People who are underweight are also at risk for serious health problems.2

The key to achieving and maintaining a healthy weight isn’t about short-term dietary changes. It’s about a lifestyle that includes healthy eating and regular physical activity.

If you are underweight, overweight, or obese, talk with your doctor about ways to reach and maintain a healthy weight before you get pregnant.

7. Get Help for Violence

Violence can lead to injury and death among women at any stage of life, including during pregnancy. The number of violent deaths experienced by women tells only part of the story. Many more survive violence and are left with lifelong physical and emotional scars.

If someone is violent toward you or you are violent toward your loved ones―get help. Violence destroys relationships and families.

9. Get Mentally Healthy

Mental health is how we think, feel, and act as we cope with life. To be at your best, you need to feel good about your life and value yourself. Everyone feels worried, anxious, sad, or stressed sometimes. However, if these feelings do not go away and they interfere with your daily life, get help. Talk with your doctor or another health professional about your feelings and treatment options.

Smokeless tobacco is associated with many health problems. Using smokeless tobacco:

  • Can lead to nicotine addiction1,2
  • Causes cancer of the mouth, esophagus (the passage that connects the throat to the stomach), and pancreas (a gland that helps with digestion and maintaining proper blood sugar levels)1,2
  • Is associated with diseases of the mouth1,3
  • Can increase risks for early delivery and stillbirth when used during pregnancy2
  • Can cause nicotine poisoning in children4
  • May increase the risk for death from heart disease and stroke1,3

Using smokeless products can cause serious health problems.
Protect your health; don’t start. If you do use them, quit.

Addiction to Smokeless Tobacco

  • Smokeless tobacco contains nicotine, which is highly addictive.1,2
  • Because young people who use smokeless tobacco can become addicted to nicotine, they may be more likely to also become cigarette smokers.5

Smokeless Tobacco and Cancer

  • Many smokeless tobacco products contain cancer-causing chemicals.1,6
    • The most harmful chemicals are tobacco-specific nitrosamines, which form during the growing, curing, fermenting, and aging of tobacco. The amount of these chemicals varies by product.1
    • The higher the levels of these chemicals, the greater the risk for cancer.2
    • Other chemicals found in tobacco can also cause cancer. These include:6
      • A radioactive element (polonium-210) found in tobacco fertilizer
      • Chemicals formed when tobacco is cured with heat (polynuclear aromatic hydrocarbons—also known as polycyclic aromatic hydrocarbons)
      • Harmful metals (arsenic, beryllium, cadmium, chromium, cobalt, lead, nickel, mercury)
  • Smokeless tobacco causes cancer of the mouth, esophagus, and pancreas.1

Smokeless Tobacco and Oral Disease

  • Smokeless tobacco can cause white or gray patches inside the mouth (leukoplakia) that can lead to cancer.1
  • Smokeless tobacco can cause gum disease, tooth decay, and tooth loss.1,3

Reproductive and Developmental Risks

  • Using smokeless tobacco during pregnancy can increase the risk for early delivery and stillbirth.2
  • Nicotine in smokeless tobacco products that are used during pregnancy can affect how a baby’s brain develops before birth.2,7

Other Risks

  • Using smokeless tobacco increases the risk for death from heart disease and stroke.1,3
  • Smokeless tobacco can cause nicotine poisoning in children.4
  • Additional research is needed to examine long-term effects of newer smokeless tobacco products, such as dissolvables and U.S. snus.

Other facts about Smoking

  • Smoking leads to disease and disability and harms nearly every organ of the body.
  • Cigarette smoking remains the leading cause of preventable disease, disability, and death in the United States.
  • The tobacco industry spends billions of dollars each year on marketing cigarettes.
  • Smoking costs the United States hundreds of billions of dollars each year.
  • States do not spend much of the money they get from tobacco taxes and lawsuits to prevent smoking and help smokers quit. CDC recommends that states spend 12% of those funds on tobacco control.
  • In 2020, 12.5% of U.S. adults (an estimated 30.8 million people) currently smoked cigarettes: 14.1% of men, 11% of women.
  • Each day, about 1,600 youth try their first cigarette.
  • Many adult cigarette smokers want to quit smoking.

Preventing Childhood Obesity: 5 Things You Can Do at Home

  • Eat the RAINBOW!
  • Move More
  • Slow Down on Sugar
  • Reduce Screen Time
  • Sleep Well

About 1 in 5 American children has obesity. Compared to children with healthy weight, children with overweight or obesity are at a higher risk for asthma, sleep apnea, bone and joint problems, type 2 diabetes, and heart disease. Children with obesity are also more likely to experience bullying, social isolation, depression, and lower self-esteem. While there is no simple solution, there are many ways parents and caregivers can help children reach a healthy weight.

Eat the Rainbow

Having a healthy diet can help children get the nutrients they need for healthy growth and development, and help them reach a healthy weight. A healthy diet is rich in fruits, vegetables, whole grains, lean proteins, and low-fat or fat-free dairy.

Unfortunately, very few people get enough fruits and vegetables. In 2017, just 2% of high school students ate enough vegetables, and 7% ate enough fruit. Help your kids eat the rainbow: make half of their plate fruits and vegetables for optimal health.

Move More

Compared to those who are inactive, physically active youth have stronger muscles and better cardiovascular fitness. They also typically have lower body fat and stronger bones. Regular physical activity in childhood also reduces the risk of depression. Children need at least 60 minutes of physical activity every day – try these tips to help your kids move more.

Slow Down on Sugar

Most of us eat and drink too many added sugars, which can lead to health problems such as weight gain and obesity, type 2 diabetes, and heart disease. Children under age 2 should have no added sugar in their diet at all, and children over age 2 should keep sugars to less than 10% of their daily calories.

A good way to slow down on sugar is by avoiding sugary drinks like soda, juice drinks, and flavored milk. Help your kids rethink their drink by offering water, plain low-fat milk, or 100% juice instead.

Reduce Screen Time

Adults and children spend over 7 hours a day being sedentary – and that doesn’t include time spent sleeping! Many of these sedentary hours are spent sitting or laying down with a phone, tablet, or computer; watching TV; or playing video games (also known as screen time).

Too much screen time has health consequences: it’s associated with poor sleep, weight gain, lower grades in school, and poor mental health in youth. When you reduce screen time, you free up time for family activities. The American Academy of Pediatrics recommends creating a family media plan, and has examples such as keeping meal times tech-free, charging devices at night outside the bedroom, turning screens off an hour before bed, and many more.

Sleep Well

Good sleep is critical to prevent type 2 diabetes, obesity, injuries, poor mental health, and problems with attention and behavior. Did you know that children 6-12 years old need 9-12 hours of uninterrupted sleep a night and youth 13-18 need 8-10 hours? Too little sleep is associated with obesity partly because inadequate sleep can make us eat more and be less physically active. Help your children sleep better by making sure they’re active during the day, removing screens from their bedrooms, and setting a consistent sleep schedule, even on weekends.

Kids imitate the adults in their lives. Be a role model for them by adopting these healthy habits, and they will too! Finally, remember that obesity is a complex disease with many contributing factors. Learn more about what states and communities can do to make healthy and active living accessible for everyone.

All about borderline diabetes (prediabetes)

We include products we think are useful for our readers. If you buy through links on this page, we may earn a small commission. Here’s our process.

A person with borderline diabetes, or prediabetes, has blood sugar levels that are higher than normal but not yet high enough for a diagnosis of type 2 diabetes.

Borderline diabetes is a condition that may lead to type 2 diabetes. According to the American Diabetes Association, an estimated 10 to 23 percent of people with borderline diabetes will go on to develop type 2 diabetes within 5 years.

Doctors may also refer to borderline diabetes as:

This article looks at how to recognize risk factors for prediabetes, how to manage the condition, and how to prevent type 2 diabetes from developing.

Symptoms

Prediabetes does not have clear symptoms. Some people may not be aware that they have it until:

  • a doctor tests blood glucose and blood pressure levels
  • prediabetes has progressed to type 2 diabetes
  • a complication occurs, such as a heart attack

If a person’s blood sugar level remains high, they may begin to develop some symptoms of type 2 diabetes. Symptoms include frequent urination and increased thirst.

Most people will not know they have prediabetes until they receive testing.

Causes and risk factors

According to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), a range of other conditions can increase the risk of prediabetes, including:

Other risk factors include:

  • not getting enough exercise
  • having a family history of type 2 diabetes.

According to the American Heart Association, the following lifestyle factors may also be a risk for prediabetes in some people:

  • raised stress levels
  • smoking
  • drinking too much alcohol

Regularly consuming high-sugar drinks may also increase the risk.

One 2017 review found that people who regularly drink sugary beverages face an increased risk of metabolic diseases, such as high blood pressure and high levels of blood glucose and fats.

These metabolic conditions can lead to prediabetes and diabetes.

People who lead an inactive lifestyle are at higher risk of taking in too many calories without burning them through exercise.

Other people who may be at risk of developing prediabetes include those with polycystic ovary syndrome (PCOS) and those who have experienced instances of high blood sugar levels in the past.

Anyone with any of these risk factors may benefit from a prediabetes screening to identify whether they have the condition.

Diagnosis

A doctor typically diagnoses prediabetes with a blood test, particularly a glucose tolerance test. A glucose tolerance test measures how quickly the body can process the sugar in the blood in a 2-hour period.

Other tests include measuring blood sugar levels after a person has not eaten for a specific period. This is called a fasting blood test.

The doctor may also use an A1C test. This involves measuring the average blood sugar levels over 2–3 months. People do not need to fast or take any special liquids or medications for this test, and it gives reliable results.

According to the American Diabetes Association, a doctor will diagnose prediabetes when test results show the following measurements:

  • fasting blood sugar levels of 100–125 milligrams per deciliter (mg/dl)
  • glucose tolerance levels of 140–199 mg/dl
  • an A1C test result of 5.7–6.4 percent

A doctor will often re-test these levels to confirm that the readings are not due to one-off spikes in blood sugar.

Blood glucose monitors for home use are available for purchase online.

Who should seek screening?

The NIDDK recommend that people with the following risk factors should undergo a prediabetes screening:

  • an age of 45 years or over
  • obesity or overweight, or a body mass index (BMI) over 25
  • a waist circumference larger than 40 inches in males or over 35 inches in females
  • a close relative with diabetes
  • a condition that increases insulin resistance, including PCOS, acanthosis nigricans, and nonalcoholic steatohepatitis
  • an ethnic background that places an individual at high risk of diabetes, including people who are African-American, Asian-American, Latino, Native American, or a Pacific Islander
  • a history of gestational diabetes, or diabetes as a result of pregnancy
  • having given birth to an infant weighing over 9 pounds
  • having a disease that harden the arteries
  • recent treatment with glucocorticoids or atypical antipsychotic medications

If a doctor identifies any of these risk factors, they may recommend that the person has a screening for blood glucose levels.

Medical professionals advise repeating screening tests every 1 to 3 years if a person has these risk factors.

The NIDDK has an official resource to check diabetes risk. Click here to take the test.

However, anyone who is concerned that they may have borderline diabetes should visit the doctor for testing and a proper diagnosis.

Treatment

Prediabetes is reversible, but it is often easier to prevent than treat. Lifestyle factors are the primary causes of prediabetes, and making changes in some aspects of life can significantly reduce risk factors.

A balanced, nutritious diet that moderates sugar intake and regular exercise can help reverse borderline diabetes.

According to the American Diabetes Association, diet and nutrition changes should include the following:

  • improving intake of unprocessed high-fiber carbohydrates
  • increasing fruit and vegetable consumption
  • reducing saturated fat and processed meat intake.

Click here to find out more about what to eat with prediabetes.

Exercise is also important. According to a report in Diabetes Care, exercise can help prevent or delay diabetes from developing.

Current guidelines for Americans recommend that adults should:

  • have at least 150–300 minutes of moderate-intensity aerobic activity each week
  • do muscle-strengthening exercises at least twice a week, such as lifting weights or doing push-ups

Examples of moderate exercise are fast dancing and brisk walking.

Regular exercise and a healthful diet not only help reduce the risk of developing diabetes but also protect the heart against future diseases.

Diabetes Prevention Program

The Diabetes Prevention Program (DPP) was a long-term study that aimed to identify practical steps for reducing diabetes risk and reversing prediabetes.

The people who took part in the DPP Lifestyle Change Program aimed to lose 7 percent of their body weight and maintain this loss through dietary changes and activity. After 3 years, the results of the program showed:

  • a 58-percent drop in the risk of developing diabetes regardless of sex or ethnicity, compared with those who took a placebo
  • a 71-percent drop in risk people of developing type 2 diabetes among people aged over 60 years

All the people in the program received motivational support on effective diet and exercise and attended “lifestyle change classes,” for the duration of the study.

Follow-ups took place regularly. After 15 years, people in the DPP Lifestyle Change Program continued to see a delay in the onset of diabetes compared to people who took a medication called metformin or a placebo.

Anyone who developed diabetes during the study received extra medical care. However, diet and exercise remained important in managing symptoms and reducing the risk of complications.

Monitoring borderline diabetes

In addition to lifestyle changes, doctors may recommend other steps for managing the risk of diabetes.

Medical management may include treating related conditions, such as obesity and heart disease.

Managing prediabetes also involves continued monitoring of the risk factors and regular testing of blood sugar levels.

A person can reverse borderline diabetes if they can make and maintain the necessary lifestyle changes.

Takeaway

Borderline diabetes is the stage before type 2 diabetes develops. By this stage, blood sugar, blood pressure, and insulin resistance may start reaching harmful levels.

Prediabetes does not usually cause active symptoms, and most people will not be aware they have the condition until it becomes diabetes and starts causing severe health problems.

It is therefore essential for anyone who is at risk of developing diabetes to receive regular screening. Risk factors include high BMI and waist circumference, an age of more than 45 years, or other cardiovascular diseases.

Prediabetes is often reversible with a sustained exercise program and a balanced, low-sugar diet.
