What gland scretes diabetes mellitus?

The pancreas secretes insulin, a hormone that helps regulate blood sugar levels. Insulin is produced by beta cells in the islets of Langerhans, which are located in the pancreas. When blood sugar levels rise after a meal, the pancreas releases insulin into the bloodstream. Insulin helps cells take up glucose from the blood and use it for energy or store it for later use. In diabetes mellitus, the body does not produce enough insulin or does not respond to insulin properly, leading to high blood sugar levels.
