Diabetes mellitus - Definition

Ask a question


Diabetes mellitus (or simply diabetes) is a chronic disease due to the insufficient production of insulin by the pancreas. This pathology is characterized by an increase in glycemia (levels of sugar in the blood) because insulin is the hormone in charge of regulating it. Diabetes is classified into two types: insulin-dependent diabetes (T1DM) or type 1 diabetes, and noninsulin-dependent diabetes (NIDDM) or type 2 diabetes. The first type generally appears suddenly in children and necessitates regular and repeated injections, several times per day. No matter which type of diabetes, it is important to closely monitor diet.
