Diabetes is a medical condition in which your body cannot use the energy from the food you eat. In diabetes, insulin (a hormone that is needed for our body to use glucose, also referred to as ‘blood sugar’) may be absent or not be used in the normal way. Either situation results in high blood sugar, or, hyperglycemia. Long term damage, dysfunction or organ failure may impact a person who is not managing their diabetes effectively. Chronic hyperglycemia may result in: eye problems, kidney problems, nerve damage, heart and blood vessel damage (atherosclerosis, hypertension, cardiovascular disease and, circulation problems), dental problems, and infections.
