glicèmia

Glicemia refers to the concentration of glucose in the blood. Glucose, a simple sugar, is the primary source of energy for the body's cells. Its level in the bloodstream is tightly regulated by hormones, primarily insulin and glucagon, produced by the pancreas. When blood glucose levels rise, typically after eating, insulin is released to help cells absorb glucose for energy or storage. If blood glucose levels drop too low, glucagon is released to stimulate the liver to break down stored glycogen into glucose, releasing it back into the bloodstream. Maintaining stable blood glucose levels is crucial for overall health. Deviations from the normal range can indicate various metabolic conditions. Persistently high blood glucose levels, known as hyperglycemia, are a hallmark of diabetes mellitus. Conversely, abnormally low blood glucose levels are called hypoglycemia and can lead to symptoms like dizziness, confusion, and in severe cases, loss of consciousness. Blood glucose is typically measured in milligrams per deciliter (mg/dL) or millimoles per liter (mmol/L). Monitoring glicemia is essential for managing diabetes and other health conditions, and it is often done through a finger-prick blood test or a continuous glucose monitor.
