Type II diabetes, also known as adult-onset diabetes, is a chronic medical condition that affects the way your body metabolizes glucose. It is the most common type of diabetes and is often caused by poor diet, lack of exercise, and obesity. In addition to Type II diabetes, it also goes by the names non-insulin-dependent diabetes mellitus (NIDDM), and maturity-onset diabetes of the young (MODY). Other less common synonyms include non-ketotic hyperglycemic hyperosmolar coma (NKHH), and Type 2 non-insulin-dependent diabetes. Despite the use of different terms, the symptoms and complications of Type II diabetes remain consistent, including damage to the eyes, kidney, nerves, and cardiovascular system.
