What is diabetes?

Diabetes is a metabolic disorder that means your body does not make enough insulin. Or it means that your body is not able to use the insulin it makes. Your body needs the hormone insulin to change blood sugar (glucose) into energy. Without insulin, too much glucose collects in your blood. Diabetes may also be a result of other conditions. These include genetic syndromes, chemicals, medicines, pancreatitis, infections, and viruses.

Diabetes can be 1 of 3 types: type 1, type 2, or gestational. All 3 are metabolic disorders that affect the way the body uses (metabolizes) food to make glucose. Glucose is the main source of fuel for the body.

Are You at Risk for Type 2 Diabetes?

Type 2 diabetes happens when the body cannot make enough insulin or is not able to use it properly. Type 2 diabetes may be controlled with diet, exercise and weight loss, or may need oral medicines or insulin injections.
