Insulin Production

Insulin production occurs in the pancreas, an organ behind the stomach. Specialized cells called beta cells in tiny clusters called islets of Langerhans release insulin in response to rising blood sugar levels after eating. Insulin acts like a key, helping cells in your body—especially muscle, liver, and fat cells—absorb glucose from the bloodstream to use for energy or store for later. This process maintains blood sugar within a healthy range. When insulin production is disrupted or insufficient, as in diabetes, blood sugar can become dangerously high, leading to various health complications.
