How Your Diet Can Prevent Insulin Resistance

Ac and insulin resistance -

Many small skin growths called skin tags often appear in these same areas. Even though blood glucose levels are not high enough to cause symptoms for most people, a few research studies have shown that some people with prediabetes may already have early changes in their eyes that can lead to retinopathy.

This problem more often occurs in people with diabetes. The most accurate test for insulin resistance is complicated and used mostly for research. Doctors most often use the fasting plasma glucose FPG test or the A1C test to diagnose prediabetes.

Less often, doctors use the oral glucose tolerance test OGTT , which is more expensive and not as easy to give.

The A1C test reflects your average blood glucose over the past 3 months. The FPG and OGTT show your blood glucose level at the time of the test. The A1C test is not as sensitive as the other tests. In some people, it may miss prediabetes that the OGTT could catch. The OGTT can identify how your body handles glucose after a meal—often before your fasting blood glucose level becomes abnormal.

Often doctors use the OGTT to check for gestational diabetes, a type of diabetes that develops during pregnancy. People with prediabetes have up to a 50 percent chance of developing diabetes over the next 5 to 10 years. You can take steps to manage your prediabetes and prevent type 2 diabetes.

You should be tested for prediabetes if you are overweight or have obesity and have one or more other risk factors for diabetes, or if your parents, siblings, or children have type 2 diabetes.

If the results are normal but you have other risk factors for diabetes, you should be retested at least every 3 years. Physical activity and losing weight if you need to may help your body respond better to insulin. Taking small steps, such as eating healthier foods and moving more to lose weight, can help reverse insulin resistance and prevent or delay type 2 diabetes in people with prediabetes.

The National Institutes of Health-funded research study, the Diabetes Prevention Program DPP , showed that for people at high risk of developing diabetes, losing 5 to 7 percent of their starting weight helped reduce their chance of developing the disease.

People in the study lost weight by changing their diet and being more physically active. The DPP also showed that taking metformin , a medicine used to treat diabetes, could delay diabetes.

Metformin worked best for women with a history of gestational diabetes, younger adults, and people with obesity. Ask your doctor if metformin might be right for you.

Making a plan , tracking your progress, and getting support from your health care professional, family, and friends can help you make lifestyle changes that may prevent or reverse insulin resistance and prediabetes. You may be able to take part in a lifestyle change program as part of the National Diabetes Prevention Program.

The National Institute of Diabetes and Digestive and Kidney Diseases NIDDK and other components of the National Institutes of Health NIH conduct and support research into many diseases and conditions.

Clinical trials are part of clinical research and at the heart of all medical advances. Clinical trials look at new ways to prevent, detect, or treat disease. Researchers also use clinical trials to look at other aspects of care, such as improving the quality of life for people with chronic illnesses.

A C-peptide test is not used to diagnose diabetes. Other tests, such as blood glucose and urine glucose , are used to screen for and diagnose diabetes. The information on this site should not be used as a substitute for professional medical care or advice.

Contact a health care provider if you have questions about your health. C-Peptide Test. What is a C-peptide test? Other names: insulin C-peptide, connecting peptide insulin, proinsulin C-peptide.

What is it used for? A C-peptide test may be used to help: Find the cause of hypoglycemia low blood sugar. Some types of hypoglycemia are linked to high insulin levels.

A C-peptide test can tell you whether too much insulin is involved in your condition. Possible causes of hypoglycemia include: Liver or kidney disease Malnutrition Drinking too much alcohol without eating A tumor in your pancreas uncommon Side effects from certain diabetes medicines , including insulin.

Manage diabetes treatment. If you have type 1 or type 2 diabetes , treatment decisions may depend on knowing how much insulin your pancreas is producing. A C-peptide test can provide an accurate measurement, even if you take insulin for diabetes.

That's because your C-peptide levels depend on how much insulin your pancreas makes. They aren't affected by insulin that you take.

Monitor treatment for a tumor in your pancreas, called an insulinoma uncommon. These tumors make too much insulin and cause low blood sugar. They are almost always benign not cancer and can usually be removed with surgery.

To find out whether you have type 1 or type 2 diabetes if your diagnosis is uncertain. Usually, your health care provider can diagnose which type of diabetes you have. But in certain cases, it can be hard to tell for sure. If your diabetes diagnosis is uncertain after 3 years, a C-peptide test may be needed.

Why do I need a C-peptide test? You may need a C-peptide test if: You have been diagnosed with hypoglycemia low blood sugar but don't know what's causing it. You have diabetes and you: Take insulin, and your provider is considering changing your treatment. Have type 2 diabetes, and your provider wants to see if you need to start taking insulin.

Have hypoglycemia, which could be caused by taking too much diabetes medicines. You have been diagnosed with a pancreatic tumor insulinoma. A C-peptide test can help monitor your condition and treatment. What happens during a C-peptide test? The test generally includes the following steps: To begin, urinate in the toilet as usual.

Do not collect this urine. Write down the time you urinated. For the next 24 hours, collect all your urine in the container.

During the collection period, store the urine container in a refrigerator or in a cooler with ice. This is the last urine collection for the test. Return the container with your urine to your provider's office or the laboratory as instructed.

Will I need to do anything to prepare for the test? Are there any risks to the test? What do the results mean? In general: A high level of C-peptide usually means that your body is making too much insulin. Conditions that cause high insulin levels include: Type 2 diabetes Cushing's syndrome Insulinoma, a tumor in your pancreas Kidney failure A low level of potassium in your blood A low level of C-peptide may mean your body isn't making enough insulin.

Conditions that cause low insulin levels include: Type 1 diabetes and, in some cases, type 2 diabetes Taking too much insulin to treat diabetes Taking more insulin than you need may block your pancreas from making insulin on its own.

A severe infection Addison disease Liver disease If you have been treated for an insulin-producing tumor in your pancreas, a decrease in your C-peptide levels means your treatment is working.

If you have questions about your results, talk with your provider. Is there anything else I need to know about a C-peptide test? References Centers for Disease Control and Prevention [Internet]. Atlanta: U.
