Four Major Types of Diabetes:

Type 1 diabetes Occurs when the body fails to produce insulin, the hormone that "unlocks" the cells of the body, allowing glucose to enter and fuel them. About 5-10% of Americans who are diagnosed with diabetes have type 1 diabetes.

Type 2 diabetes - Results from insulin resistance (a condition in which the body fails to properly use insulin), and after several years, the insulin production decreases. Most Americans, about 90 95%, who are diagnosed with diabetes have type 2 diabetes.

Gestational diabetes is a type of diabetes that only pregnant women get. If not treated, it can cause problems for mothers and babies. Gestational diabetes affects about 4% of all pregnant women. Women who have had gestational diabetes have a 20% to 50% chance of developing diabetes in the next 5-10 years.

Pre-diabetes - Pre-diabetes is a condition that occurs when a person's blood glucose levels are higher than normal but not high enough to be diagnosed as diabetes.
