What is Insulin


What is insulin? Insulin is a hormone made by the pancreas that helps keep blood sugar levels normal. Insulin helps your body take sugar out of your blood and use it for energy. You may need to take insulin because your pancreas is not making enough.

What are the different types of insulin? Several types of insulin are used to lower blood sugar. Some types of insulin are clear and some are cloudy. Each type of insulin has a different onset, peak response, and duration. The onset is how soon the insulin starts to work in the blood. The peak response is when the insulin has the greatest effect on blood sugar levels. The duration is how long the insulin lasts. Ask your caregiver for more information on the type of insulin you need, how often to take it, and how to use it. Common types are:

What will my insulin treatment plan be? You may need 1 type of insulin or a combination of 2 or more types. Your caregiver will work with you to find the treatment plan that works best. Your insulin needs may change because of illness, stress, medicines, diet changes, or physical activity. You may need to check your blood sugar level at least 3 times each day. Ask what your blood sugar levels should be before and after you eat. Write down your results and show them to your caregiver. He may use the results to make changes to your medicine, food, or exercise schedules.

How is insulin measured and given? Insulin is measured in units. U100 is the most common type of insulin. It has 100 units of insulin in 1 mL of solution. U500 insulin has 500 units of insulin in 1 mL. Insulin is usually given in the following ways:

How should I store insulin? Follow the storage directions on the label or package insert that came with the insulin. If insulin has been frozen or exposed to very warm temperatures (above 85° F), throw it away.
