Just two organs in your body need insulin to function: the liver and adipose tissue. Too much insulin can get in the way, forcing glucose clearance from the bloodstream into tissues. It can also lead to hypoglycemia (low blood glucose) and inadequate glucose delivery to the brain, which can make you dizzy or unconscious or seize or die, depending on its severity. The pancreas senses the drop in the blood glucose, and stops releasing insulin before you lose consciousness.
