While insulin is involved in these conditions, the dangers of uncontrolled levels of insulin show to be more life-threatening. Insulin is a hormone that plays an essential role in digestion and metabolism because it allows glucose to enter the body's cells to provide energy. It is also responsible for regulating the storage of excess glucose in the liver, muscles and fat cells.
