Diabetes is a condition that occurs when your blood sugar (glucose) levels are too high. This happens when the pancreas does not produce enough insulin, produces none at all, or when the body doesn’t respond properly to insulin. Diabetes can affect people of any age. Most types of diabetes are chronic and require lifelong management, but all forms can be controlled with medication and/or lifestyle changes.
Glucose, which comes primarily from the carbohydrates in your food and drinks, is the body’s main source of energy. Your blood transports glucose to all of your body’s cells for energy use.
