What is Insulin and Why Do You Need It?1

Insulin is a hormone that's made by your pancreas. The purpose of insulin is to help your body move glucose into cells for energy.

How Insulin Controls Your Blood Sugar (Glucose) Level2

When your pancreas cannot produce enough insulin or fails to function properly, your blood sugar (glucose) level can rise — leading to diabetes.

If you are diagnosed with diabetes, you may need insulin treatment to help you control your blood sugar (glucose) level.

What You Need to Know About Insulin and Type 2 Diabetes1

Everybody needs insulin to help move sugar (glucose) from the blood into cells where it can be used for energy. It doesn’t matter whether a person gets insulin from their pancreas or insulin treatment — everyone needs insulin.

In type 2 diabetes, there is a gradual loss of the cells that produce insulin, called beta cells. The loss of these cells makes it increasingly difficult to manage blood sugar (glucose) levels, which is why many people living with type 2 diabetes eventually need insulin treatment.

What Types of Insulin Are There?4

Insulin types vary according to how soon they start to work, how long they take to kick into full effect, and how long they last.

Some can work for longer periods of time while others work for shorter periods of time.

There are even different types of faster-acting and longer-acting insulin, as well as a type of insulin that is a combination of faster-acting and longer-acting insulin called mixed insulin.

Remember — Your doctor will recommend the type of insulin that's right for you.
