Hypoglycemia or blood sugar is a disorder of blood sugar metabolism which may result in diabetes in later life. It is a condition in which the pancreas produces too much insulin, causing the blood sugar to drop.

Hypoglycemia sometimes occurs in healthy people some hours after a meal rich in carbohydrates, especially following muscular exertion. It is frequently found in the first few days of life, especially among premature infants.

Hypoglycemia is a serious disorder as the brain cannot function properly when the blood sugar level is too low. Like all other organs of the body, the brain receive its fuel from the diet. But it can use only the sugar produced by the body from carbohydrates. Unlike many of the body tissues, it cannot store its fuel. Therefore, it must get a constant supply of sugar through the bloodstream. Mental disturbances caused by subnormal blood sugar levels can seriously affect a person’s life.
