Diabetes, often referred to by doctors as diabetes mellitus, describes a group of metabolic diseases in which the person has symptoms of 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. Patients with high blood sugar will typically experience polyuria, they will become increasingly thirsty and hungry. Controlling blood sugar (glucose) levels is the major goal of adult diabetes treatment, in order to prevent complications of the disease. Type 1 diabetes is managed with insulin as well as dietary changes and exercise. Type 2 diabetes may be managed with non-insulin medications, insulin, weight reduction, or dietary changes. Endocrinologists are the specialists in endocrine disorders such as diabetes and as such, manage many patients with diabetes. Primary care specialists, including internists and family practice specialists, may also treat patients with diabetes. People with diabetes deal with health problems every single day. If symptoms of adult diabetes are poorly controlled or left untreated, it may lead to blindness, kidney disease, blood vessel damage, infection, heart disease, nerve damage, high blood pressure, stroke, limb amputation, and coma. The cost of adult diabetes treatment includes medicines and insulin expenditure. Another crucial element in a treatment program for diabetes is exercise. It improves the body's use of insulin and may lower blood sugar levels.
