Diabetes Basics

While diabetes and prediabetes occur in people of all ages and races, some groups have a higher risk for developing the disease than others. Diabetes is more common in African Americans, Latinos, Native Americans, and Asian Americans/Pacific Islanders, as well as the aged population. This means they are also at increased risk for developing prediabetes or diabetes.

There are three different tests your doctor can use to determine whether you have prediabetes or diabetes:

• The A1C test
• The fasting plasma glucose test (FPG)
• or the oral glucose tolerance test (OGTT).

The blood glucose levels measured after these tests determine whether you have a normal metabolism, or whether you have prediabetes or diabetes.

If your blood glucose level is abnormal following the FPG, you have impaired fasting glucose (IFG); if your blood glucose level is abnormal following the OGTT, you have impaired glucose tolerance (IGT). Both are also known as prediabetes.

The American Diabetes Association Risk Test for Diabetes can help you determine if you are at increased risk for diabetes or prediabetes. A high score may indicate that you have prediabetes or at risk for diabetes. Take the test and find out for sure.
