vércukorszintet

Vércukorszint refers to the concentration of glucose, a type of sugar, in the blood of humans and other animals. Glucose is the primary source of energy for the body's cells, and maintaining it within a specific range is crucial for proper bodily function.

Several hormones regulate blood glucose levels. Insulin, produced by the pancreas, lowers blood glucose by helping cells absorb glucose from the bloodstream and by promoting its storage as glycogen in the liver and muscles. Glucagon, also produced by the pancreas, raises blood glucose by stimulating the liver to release stored glycogen as glucose into the blood.

Factors influencing blood glucose levels include food intake, physical activity, stress, and certain medications. After eating, carbohydrate-rich foods are broken down into glucose, causing blood sugar to rise. Exercise generally lowers blood glucose as muscles use more glucose for energy.

Abnormal blood glucose levels can indicate various health conditions. Persistently high blood glucose is characteristic of diabetes mellitus, a chronic metabolic disorder. Low blood glucose, known as hypoglycemia, can cause symptoms such as dizziness, confusion, and, in severe cases, unconsciousness.

Monitoring blood glucose levels is essential for individuals with diabetes to manage their condition effectively and prevent complications. This can be done through self-monitoring devices or by healthcare professionals.
