The fluctuation of blood<unk>  (red) and the<unk> -lowering hormone insulin (blue) in humans during the course of a day with three meal. One of the effects of a<unk> -rich vs a starch-rich meal is highlighted. The glycaemia, also known as<unk> , blood<unk>  concentration, or blood glucose<unk>  is the measure of glucose concentrated in the blood of humans or other animals. Approximately 4 grams of glucose, a simple<unk> , is present in the blood of a 70 kg (154 lb) human at all times. The body tightly regulates blood glucose<unk> s as a part of metabolic homeostasis. Glucose is stored in skeletal muscle and liver cells in the form of glycogen; in fasting individuals, blood glucose is maintained at a constant<unk>  at the expense of glycogen stores in the liver and skeletal muscle. In humans, a blood glucose<unk>  of 4 grams, or about a teaspoon, is critical for normal function in a number of tissues, and the human brain consumes approximately 60% of blood glucose in fasting, sedentary individuals. A persistent elevation in blood glucose leads to glucose toxicity, which contributes to cell dysfunction and the pathology grouped together as complications of diabetes. Glucose can be transported from the intestines or liver to other tissues in the body via the bloodstream. Cellular glucose uptake is primarily regulated by insulin, a hormone produced in the pancreas. Glucose<unk> s are usually lowest in the morning, before the first meal of the day, and rise after meals for an hour or two by a few millimoles.<unk> s outside the normal range may be an indicator of a medical condition. A persistently high<unk>  is referred to as hyperglycemia; low<unk> s are referred to as hypoglycemia. Diabetes mellitus is characterized by persistent hyperglycemia from any of several causes, and it is the most prominent disease related to the failure of blood<unk>  regulation. There are different methods of testing and measuring<unk> s. The intake of alcohol causes an initial surge in blood<unk>  and later tends to cause<unk> s to fall. Also, certain drugs can increase or decrease glucose<unk> s.
