Prediabetes

Condition Basics

What is prediabetes?

Prediabetes is a warning sign that you are at risk for getting type 2 diabetes. It means that your blood sugar is higher than it should be. But it's not high enough to be diabetes.

The food you eat naturally turns into sugar. Your body uses the sugar for energy. Normally, an organ called the pancreas makes insulin. Insulin allows the sugar in your blood to get into your body's cells. But sometimes the body can't use insulin the right way. So the sugar stays in your blood instead. This is called insulin resistance. The buildup of sugar in your blood means you have prediabetes.

Prediabetes is also called impaired glucose tolerance or impaired fasting glucose. Most people who get type 2 diabetes have prediabetes first.

What causes it?

Prediabetes is caused by a buildup of sugar in your blood. Insulin allows sugar to get into your body's cells. When your body can't use insulin the right way, the sugar doesn't move into your body's cells. And that's how it builds up in your blood.

What are the symptoms?

Most of the time, people with prediabetes do not have symptoms.

How is it diagnosed?

Your doctor will ask questions about your medical history. You will also get a physical exam and blood glucose testing. The results help your doctor see if you have prediabetes and are at risk for type 2 diabetes.

How is prediabetes treated?

Prediabetes can be treated by making lifestyle changes, taking medicine, or doing both. Lifestyle changes include losing weight if you need to, having healthy eating habits, and being active. Treatment may help get your blood sugar level back to a more normal range. It could help you prevent or delay type 2 diabetes.
