Insulin

Insulin lowers blood sugar by allowing it to leave the bloodstream and enter cells. Everyone needs insulin. People with type 1 diabetes can't make their own insulin. They must take insulin every day. Insulin is usually injected under the skin. In some cases, a pump delivers the insulin continuously. Insulin does not come in pill form. Insulin preparations differ in how fast they start to work and how long they last. The health care professional will review your blood glucose levels to determine the appropriate type of insulin you should use. More than one type of insulin may be mixed together in an injection to achieve the best blood glucose control.
