How Insulin Signals Your Cells to Absorb Sugar From the Blood
How Insulin Works In The Body: Every time you eat food containing carbohydrates, your body breaks it down into glucose, also called sugar. This sugar enters your bloodstream and becomes a major source of energy for your cells. However, glucose cannot enter most cells on its own. It needs help from a hormone called insulin. Insulin is made by the pancreas, an organ located behind the stomach. After you eat, the pancreas releases insulin into the bloodstream. Insulin then travels through the body and acts like a signal that tells cells to open up and absorb sugar from the blood. Without insulin, sugar stays in the bloodstream instead of moving into cells. Over time, this can lead to serious health problems such as diabetes and damage to organs, nerves, and blood vessels.
