Diabetes mellitus, or diabetes, is a metabolic condition characterized by excessive blood sugar levels. Insulin transfers sugar from the bloodstream into your cells, where it is stored or used for energy. Your body either doesn't generate enough insulin or can't use the insulin it does make effectively if you have diabetes. The symptoms of diabetes are carried on by a rise in blood sugar. The majority of people who present with the characteristic symptoms of diabetes get a straightforward diagnosis. The purpose of diabetes management is to improve persons with diabetes' quality of life and productivity.
