What is Prediabetes?
According to the American Diabetes Association before people develop type 2 diabetes, they almost always suffer from "prediabetes" — that’s when blood glucose levels are higher than normal, but not high enough to be diagnosed as diabetes.
Research shows that some long-term damage to the body, especially the heart and circulatory system, may occur during prediabetes.
Diet, exercise, stress, medicines, and other factors can lead to high blood sugar levels.
There are three different tests a doctor can administer to determine whether a person has prediabetes:
- 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 a person has a normal metabolism, or whether they have prediabetes or diabetes.
If a person’s blood glucose level is abnormal following the FPG, they have impaired fasting glucose (IFG); if their blood glucose level is abnormal following the OGTT, they have impaired glucose tolerance (IGT). Both are also known as prediabetes.
