vércukorszintszabályozó

Vércukorszint refers to the concentration of glucose (sugar) in the blood. 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. The body regulates blood glucose levels through hormones, primarily insulin and glucagon, produced by the pancreas. Insulin helps lower blood glucose by enabling cells to absorb glucose from the bloodstream and by promoting its storage in the liver and muscles. Glucagon, on the other hand, raises blood glucose levels by signaling the liver to release stored glucose.

Blood glucose levels fluctuate throughout the day, typically rising after meals containing carbohydrates and falling during periods of fasting or physical activity. Normal fasting blood glucose levels usually range between 70 and 100 milligrams per deciliter (mg/dL). After eating, levels may rise to below 140 mg/dL within two hours. Deviations from these normal ranges can indicate health issues. Consistently high blood glucose levels (hyperglycemia) are a hallmark of diabetes mellitus, a condition where the body either doesn't produce enough insulin or its cells don't respond properly to insulin. Conversely, persistently low blood glucose levels (hypoglycemia) can also be problematic, leading to symptoms like dizziness, confusion, and even loss of consciousness. Monitoring blood glucose levels is essential for managing diabetes and diagnosing other metabolic disorders.
