Question

Why do under secretion of insulin cause diabetes

Answer 1

Decrement in secretion of insulin causes diabetes

Answer 2

Insulin and glucagon are hormones secreted by islet cells within the pancreas. They are both secreted in response to blood sugar levels, but in opposite fashion! Insulin is normally secreted by the beta cells (a type of islet cell) of the pancreas. ... If blood glucose is high, then no glucagon is secreted.
