Blood Glucose

Blood glucose, also called blood sugar, concentration indicates the level of glucose in a person's blood and is measured in the US in weight (milligrams) per volume (deciliter) or short mg/dL.

Blood glucose levels are tightly regulated by the body and change depending on the time point measured, i.e. before or after meals. In the morning, before breakfast, blood glucose levels are low (= "fasting level") and rise after a meal for 1-2 hours. Exercising can lower blood glucose levels again.

Diabetes is characterized by persistently high levels. See Figure 1 for target values of a diabetic person.

Blood glucose concentration can be measured by a blood glucose meter. Keeping track of blood glucose levels is an integral part of managing diabetes.

A table of the time the blood glucose was checked, and the target blood glucose range for most people. Before meals, the blood glucose level should be 70 to 130 milligrams per decilitre. Two hours after meals the blood glucose should be less than 180 milligrams per deciliter. At bedtime, the blood glucose level should be between 90 and 150 milligrams per decilitre.
