Hypoglycemia
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 receives 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.

Symptoms
A craving for sweets and starches in excessive amount between meals is the first sign of low blood sugar level. When the blood sugar level falls much below normal, symptoms such as nervousness, irritability, fatigue, depression, disturbed vision and headache appear. Other symptoms are sweating, trembling, numbness, absent-mindedness, dizziness, palpitation of the heart and some sexual disturbances. Most hypoglycemia patients feel hungry and eat frequently to get over the feeling of weakness and emotional irritability. They feel tense if they have to go without food for several hours.

Causes
Hypoglycemia is usually caused by an excessive intake of refined carbohydrates and sugar foods. These substances cause the pancreas, the adrenal gland and the liver to lose their ability to handle the sugar properly. Other causes of low blood sugar are a tumor, disturbed functioning of the liver, pituitary gland or adrenal glands. Stress intensifies this condition as it weakens the adrenal glands and starts a faulty pattern of glucose intolerance.
