How High Does Glucose Have To Be To Be Classed As Too High?

A person who does not suffer from diabetes should have, on an average, between four and eight mmol per litre of glucose in the body. A person who suffers from diabetes has too much glucose or sugar in the blood. This is because his or here pancreas are unable to produce enough insulin.

Apart for being an essential source of energy for the brain, glucose is also an important source of energy for the body. Foods which are rich in carbohydrates are an important source of glucose in the bloodstream. These foods are changed into glucose after a person eats them.

Glucose is also produced by the liver. It converts fat and protein into glucose. This ensures that our body continues to get a constant supply of glucose even when we are not eating. Insulin performs two functions in the body, namely to transport glucose from the blood supply into the fat and muscle cells and to switch off the liver when the level of glucose is high enough.
