Types of Insulin

Insulin is a type of hormone. It helps the body use blood sugar (glucose) for fuel. You may need insulin injections to help manage your diabetes. With this condition, your body may not make enough insulin. Or, your cells may have trouble using insulin. There are many types of insulin that can be prescribed for your treatment. Your doctor will work with you to find the types that are best for you. Most insulin is made in a lab. It’s called human insulin because it’s just like the insulin that’s made in the body. Some types of insulin work fast. Other types work slowly and last longer.
