Blood sugar
From Wikipedia, the free encyclopedia
In medicine, blood sugar is a term used to refer to levels of glucose in the blood. Blood sugar concentration, or serum glucose level, is tightly regulated in the human body. Glucose, transported via the bloodstream, is the primary source of energy for the body’s cells.
Normally, blood glucose levels stay within narrow limits throughout the day: 4 to 8 mmol/l (70 to 150 mg/dl). Levels rise after meals and are usually lowest in the morning, before the first meal of the day.
Diabetes mellitus is the most prominent disease related to failure of blood sugar regulation.
Though it is called “blood sugar”, other sugars besides glucose are found in the blood, like fructose and galactose. However, only glucose levels are regulated via insulin and glucagon.
