Question

Write briefly about the causes of diabetes mellitus.

Answer 1

Diabetes mellitus is caused by a deficiency or inefficiency of the hormone insulin:

• Type 1 Diabetes: The immune system destroys insulin-producing cells in the pancreas, leading to little or no insulin production.
• Type 2 Diabetes: The body develops resistance to insulin, and the pancreas cannot produce enough to compensate.
• Contributing Factors: It is heavily influenced by genetics and lifestyle factors such as obesity and inactivity.
