Glucose homeostasis is the process by which the body maintains stable levels of glucose in the bloodstream. This balance is crucial for providing energy to cells and ensuring proper functioning of organs. The body uses hormones like insulin and glucagon to regulate glucose levels, responding to changes in food intake and energy needs. When you eat, insulin is released to help cells absorb glucose, lowering blood sugar levels. Conversely, when blood sugar drops, glucagon signals the liver to release stored glucose. This dynamic regulation helps keep glucose levels within a healthy range, preventing conditions like diabetes.
