Type 1 diabetes
Type 1 results from your body’s failure to produce insulin, a hormone that “unlocks” the body’s cells and allows glucose to fuel them. About five percent of Americans with diabetes have type 1, which is typically diagnosed in children or young adults.
Type 2 diabetes
Type 2 results from insulin resistance – a condition in which the body fails to properly use insulin – combined with insulin deficiency. Most Americans with diabetes have type 2.
Gestational diabetes
Immediately after pregnancy, five to 10 percent of women who have gestational diabetes are found to have diabetes, typically type 2.
Prediabetes
There are about 57 million Americans with prediabetes. This condition occurs when your blood glucose levels are higher than normal, but not high enough for a diagnosis of type 2 diabetes.
