Insulin is a naturally occurring hormone secreted by the pancreas. Many people with diabetes are prescribed insulin, either because their bodies do not produce insulin (type 1 diabetes) or do not use insulin properly (type 2 diabetes).
There are more than 20 types of insulin sold in the United States. These insulins differ in how they are made, how they work in the body and how much they cost. Your doctor will help you find the right type of insulin for your health needs and your lifestyle.
