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. When glucose levels rise after eating, the pancreas releases insulin, a hormone that helps cells absorb glucose and lowers blood sugar levels. Conversely, when glucose levels drop, the pancreas secretes glucagon, which signals the liver to release stored glucose into the bloodstream. This dynamic regulation ensures that the body has a consistent supply of energy, preventing conditions like hypoglycemia (low blood sugar) and hyperglycemia (high blood sugar).
