Question

Diabetes mellitus is caused due to destruction of β cells in Islets of Langerhans.

• A. Destruction of α cells in Islets
• B. Destruction of β cells in Islets

Answer 1

The correct option is A

Destruction of α cells in Islets

Insulin-dependent diabetes is due to the destruction of the beta cells (secrete insulin) in the Islets of Langerhans. This causes decreased insulin production, leading to elevated blood sugar and hence, diabetes mellitus. Treatment for this is to provide supplemental insulin. Blood glucose level charting is done to determine the exact dosage required for each patient.
