What is diabetes?

According to the National Centers for Disease Control and Prevention (CDC), diabetes is a disease in which blood glucose levels are above normal. Most of the food we eat is turned into glucose, or sugar, for our bodies to use for energy. The pancreas, an organ that lies near the stomach, makes a hormone called insulin to help glucose get into the cells of our bodies. When you have diabetes, your body either doesn't make enough insulin or can't use its own insulin as well as it should. This causes sugar to build up in your blood.  Diabetes can cause serious health complications including heart disease, blindness, kidney failure, and lower-extremity amputations.

The three main types of diabetes are: type 1 diabetes, type 2 diabetes, and gestational diabetes.  Another condition called prediabetes is almost always a precursor to type 2 diabetes. Modest behavior changes can prevent or delay the onset of type 2 diabetes in people who have prediabetes.
