A person experiencing diabetes wears an insulin pump because pumps assure proper dosage of insulin into the body each moment. Diabetes is a chronic, life-long endochrine disease wherein the metabolism of glucose and fats is disturbed. A daibetic can’t control the blood glucose level... which can go very high. Insulin is a hormone that controls the blood glucose level. In diabetes either there isn’t enough insulin in the body or the target organs don’t react properly with normal amounts of insulin. Synthetic insulin is the most recent cure for diabetes. Insulin can be taken with injections or pumps. Insulin must be taken during a diabetic's entire life in proper doses.
