blodglukose

Blodglukose, also known as blood glucose or blood sugar, refers to the concentration of glucose, a simple sugar, circulating in the bloodstream. Glucose is the primary source of energy for the body's cells and is obtained from the digestion of carbohydrates in food. The level of blood glucose is tightly regulated by hormones, primarily insulin and glucagon, produced by the pancreas. Insulin helps to lower blood glucose levels by facilitating glucose uptake into cells and storage as glycogen in the liver and muscles. Glucagon, on the other hand, raises blood glucose levels by stimulating the breakdown of glycogen and the production of glucose in the liver.

Normal blood glucose levels typically range between 70 and 100 milligrams per deciliter (mg/dL) when fasting. After a meal, blood glucose levels rise, but healthy individuals usually see them return to the normal fasting range within a couple of hours. Deviations from these normal ranges can indicate various health conditions. Persistently high blood glucose levels, known as hyperglycemia, are characteristic of diabetes mellitus. This condition arises from either insufficient insulin production or the body's inability to effectively use insulin. Conversely, excessively low blood glucose levels, or hypoglycemia, can be caused by factors such as too much insulin, skipping meals, or strenuous exercise without adequate food intake. Symptoms of hypoglycemia can include shakiness, sweating, confusion, and dizziness. Monitoring blood glucose levels is crucial for managing diabetes and ensuring overall metabolic health.
