Diabetes mellitus (or diabetes) is a chronic, lifelong condition that affects your body’s ability to use the energy found in food.
There are three major types of diabetes:
type 1 diabetes,
type 2 diabetes,
All types of diabetes mellitus have something in common. Normally, your body breaks down the sugars and carbohydrates you eat into a special sugar called glucose. Glucose fuels the cells in your body. But the cells need insulin, a hormone, in your bloodstream in order to take in the glucose and use it for energy. With diabetes mellitus, either your body doesn’t make enough insulin, it can’t use the insulin it does produce, or a combination of both.
