Document Summary
Diabetes mellitus is a chronic multisystem disorder of glucose metabolism related to absent or insufficient insulin supplies and/or poor utilization of the insulin that is available. The two most common types of diabetes are classified as type 1 or type 2 diabetes mellitus. Gestational diabetes, prediabetes, and secondary diabetes are other classifications of diabetes commonly seen in clinical practice. Type 1 diabetes mellitus most often occurs in people who are under 30 years of age, with a peak onset between ages 11 and 13, but can occur at any age. Type 1 diabetes is the end result of a long-standing process where the body"s own t cells attack and destroy pancreatic beta cells, which are the source of the body"s insulin. Because the onset of type 1 diabetes is rapid, the initial manifestations are usually acute. The classic symptoms are polyuria, polydipsia, and polyphagia.
