Diabetes, often referred to as diabetes mellitus, describes a group of metabolic diseases in which the person has high blood glucose (blood sugar), either because insulin production is inadequate, or because the body's cells do not respond properly to insulin, or both. Diabetes is a disorder of metabolism, the process by which the body uses digested food for energy. The digestive tract breaks down carbohydrates, sugars and starches found in many foods, into glucose, a form of sugar that enters the bloodstream. Type 1 diabetes, Type 2 diabetes and Gestational diabetes are the three types of diabetes. There are mainly three types of diabetes treatment which include insulin, oral antidiabetic drug (OAD) and glucagon-like-peptide-1 (GLP-1).
