There are three types of diabetes: type 1, type 2 and gestational. All are metabolic disorders that affect how the body uses (metabolizes) food to make glucose. Glucose is the main source of fuel for the body. Diabetes is a metabolic disorder where the body does not make enough insulin or that your body is not able to use the insulin it does make. Your body needs the hormone insulin to change blood sugar (glucose) into energy. Without insulin, too much glucose collects in your blood.
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.
