NIDDM is an acronym for non-insulin dependent diabetes mellitus, which is a metabolic disorder characterized by increased levels of blood glucose. Synonyms for this condition include Type 2 diabetes, adult-onset diabetes, and non-insulin requiring diabetes. Type 2 diabetes is a chronic disease that affects the way the body processes blood sugar. The condition is caused by a combination of genetic and lifestyle factors such as obesity, physical inactivity, and unhealthy eating habits. While medications, lifestyle changes, and other treatments can help people with NIDDM manage their blood sugar levels, it is important to seek medical attention if one experiences any symptoms or complications associated with this condition.
