1. Type 1 diabetes mellitus
It is also called insulin-dependent diabetes (IDDM) or juvenile diabetes, because type 1 diabetes usually develops in children and teenagers, though it can develop at any age and is characterized by a severe deficiency in insulin secretion resulting from atrophy of the islets of Langerhans and causing hyperglycemia and a marked tendency toward ketoacidosis.
Causative factors for type 1 diabetes mellitus:
The exact cause of type 1 diabetes is not known, researchers believe the disease develops when a virus or environmental toxin damages the pancreas or causes the body’s immune system to attack the beta cells of the pancreas As a result, the beta cells of the pancreas can no longer produce enough insulin. Genetics may play a role in this process, and exposure to certain viruses may trigger the disease.
