Types of Diabetes

Prediabetes and Type 2 are the most common types of diabetes

About 29 million people in America have diabetes, and many of them are unaware of it. About 89 million people in America have prediabetes. That’s one in three adults, and many of them don’t even know they have it.


Prediabetes occurs when a person’s blood sugar levels are higher than normal but not high enough to be diagnosed as diabetes. People who are overweight, not physically active and have a family history of diabetes, and women who develop gestational diabetes during pregnancy, are at greater risk for prediabetes.

Research shows that if you take action to manage your blood sugar levels when you have prediabetes, you can delay or prevent type 2 diabetes. Weight loss, healthy eating and increasing physical activity/exercise are effective ways to treat prediabetes. There is a proven program that can help you prevent or delay getting type 2 diabetes – the National Diabetes Prevention Program, and it’s offered by the Bryan Diabetes Center.

Type 1 Diabetes

People with type 1 diabetes must take insulin because their bodies produce little or no insulin. Type 1 diabetes can occur at any age but is most commonly seen in younger people.

Type 2 Diabetes

Type 2 is the most common form of diabetes. It occurs when your body either does not produce enough insulin or cannot use the insulin produced properly. Type 2 diabetes is a serious condition.

Controlling your blood sugar levels is the key to managing your diabetes. Healthy eating, exercise, weight loss if needed, blood glucose (sugar) testing and monitoring, and medications if prescribed, are important for effective control. Education and support can help you be successful in managing your blood sugar levels.

Gestational Diabetes

Gestational diabetes, or gestational diabetes mellitus (GDM), occurs when blood sugar levels are higher than they should be during pregnancy for a woman who does not have diabetes. This happens because the placenta produces many hormones that make it difficult to keep blood sugar levels in normal ranges.
