What is blood glucose level?

Blood glucose level or blood sugar level is the amount of sugar that is moved through the bloodstream to supply the body with energy, reports MNT. Glucose is made from carbohydrates, notes WebMD. After carbohydrates are consumed and digested, they are broken down into sugar molecules, says MNT.

The body controls blood glucose levels to keep the blood’s internal environment stable, says MNT. According to WebMD, insulin is a hormone that is produced in the pancreas and assists the body’s cells in using glucose. Glucose can only enter a cell if insulin is present in the bloodstream as well, reports MNT.
