Glükózszint

Glükózszint refers to the concentration of glucose, a simple sugar, in the bloodstream. Glucose is the primary source of energy for the body's cells and is absorbed from digested food. Maintaining a stable blood glucose level, also known as blood sugar, is crucial for proper bodily function.

The level of glucose in the blood is regulated by hormones, primarily insulin and glucagon, which are produced by the pancreas. Insulin lowers blood glucose by promoting its uptake into cells, while glucagon raises it by stimulating the liver to release stored glucose.

Normal blood glucose levels typically range between 70 and 100 milligrams per deciliter (mg/dL) when fasting. After a meal, these levels can rise temporarily. Consistently high blood glucose levels, known as hyperglycemia, can indicate conditions like diabetes mellitus. Symptoms of hyperglycemia can include increased thirst, frequent urination, fatigue, and blurred vision.

Conversely, low blood glucose levels, or hypoglycemia, can occur due to various factors, including certain medications, excessive alcohol consumption, or insufficient food intake. Symptoms of hypoglycemia may include shakiness, sweating, dizziness, confusion, and in severe cases, loss of consciousness.

Monitoring blood glucose levels is an important aspect of managing diabetes and other metabolic disorders. This is often done using a glucose meter or continuous glucose monitoring (CGM) devices. Dietary choices, physical activity, and medication play significant roles in regulating an individual's glükózszint.
