INJECT INSULIN | Where to Inject Your Insulin?


When you inject your insulin, the needle should be inserted deeply enough to reach the fatty tissue layer under the skin. The needle should avoid to go so deeply that it enters a muscle. If insulin is injected into a muscle, it is absorbed faster than it should be, and the effect on your blood sugar becomes less predictable.

This article addresses the following topics:
  • Insulin injection areas.
  • Insulin injection sites.
  • Insulin injection site rotation within an area.


Insulin Injection Areas.

The fatty tissue under the skin is the best place to inject your insulin.
Areas of your body to inject your insulin include:
  • the abdomen
  • the upper arms
  • the outside of the thighs
  • the hips and buttocks

Insulin enters the blood faster from some areas than from others. Because of this, your blood sugar may be affected differently when different areas are used for injections. If you use the same general area for all injections, it will be easier to predict how the insulin will affect your blood sugar. You still need to move to a new spot or site within this general area for each injection so that you do not build up a lump of fat from frequent injections into a small spot.

Many people use the abdomen for short-acting insulin and the thigh for the longer-acting type.

If you change to a new area for injection, you should test your blood sugar more often. Observe the test results carefully to learn how your blood sugar reacts to the change.

Insulin Injection Sites.

There are many injection sites within each area of the body that are suitable for your insulin injections. It is important to use a different site for each injection of insulin. For example, if you normally inject your short-acting insulin in the abdomen, you should not choose exactly the same site on the abdomen to take the shot every day.

Injecting insulin into the same site every day can cause a hard lump of fat to form under the skin. The absorption of insulin from this hard lump of fat is unpredictable. Do not use any injection site where a lump has formed. These lumps can sometimes disappear if simply ignored.

Insulin Injection Site Rotation Within An Area.

Try to establish a regular pattern of selecting an injection site. Jumping from site to site without a plan makes it harder to remember where you took your last shot. When you use many sites in an area and follow your plan, no one site has to be used too often. The diabetes care team can show you examples of site rotation patterns.
