What Is Blood Glucose?
Blood glucose, also called blood sugar, is the amount of glucose circulating in the bloodstream. Glucose is the body’s primary source of energy and comes mainly from the foods we eat. The hormone insulin helps move glucose from the bloodstream into the body’s cells, where it is used for energy.
Keeping blood glucose within a healthy range is essential for overall health and is especially important for people living with diabetes.

Blood glucose that is too high or too low can affect nearly every organ in the body. Long-term uncontrolled blood sugar increases the risk of heart disease, kidney disease, nerve damage, vision problems, and other serious complications.
