Hypoglycemia is a condition where the balance between the hormone insulin and sugar in body gets disturbed. Hormone insulin controls the quantity of sugar in body and do not allow the level of sugar to rise.But when a person suffers from Hypoglycemia, the condition acts as if there is more than enough insulin in the person’s blood and thus the blood sugar level of that person decreases. recent study ran by the scientists of the University of Cambridge reported that a fatal form of hypoglycemia is genetic. Hypoglycemia means low level of sugar in blood. It causes lack of energy in human body to properly function. Scientists asserted that the cause of that disease lies somewhere in genetic mutation.
