ROTATING INJECTION SITES

If you notice lumps accumulating around the area where you inject insulin, you may need to

change up your injection site. Not rotating your insulin injection or insulin pump sites enough

can lead to complications, but there are simple steps you can take to avoid these.

Consequences of Injecting at the Same Site

Lipohypertrophy: A build-up of fat cells

from repeated injections at the same site, as

seen in the pictures to the left. These lumps

will feel spongy, and thickening of the skin

at that location often accompanies it.

Scar tissue: This will feel like a hard

bump at the injection site.

Poor and/or delayed insulin absorption,

resulting in a time of high blood glucose (hyperglycemia) followed by a time of low blood

glucose (hypoglycemia). This is because scar tissue is not as effective at absorbing insulin as

undamaged skin.

Infection at the site: Signs include redness, pain or itching, and increased heat at the area.

Swelling at the site.

To allow proper healing of formed scar tissue, avoid injecting at that area for at least 6 months.

Tips for Rotating Sites and Preventing Infection

1. Using a pattern will make it easier to

remember where you last injected.

The picture to the right gives some

suggestions, but you can use whatever

pattern will be memorable to you.

2. Try not to inject in the same spot

twice in two weeks.

3. Leave 2 inches of space between sites,

and around the bellybutton.

4. Use a new needle every time, and

wash your hands before and after

injection.

5. Inject directly into the skin instead of

through clothing.

6. If you use an insulin pump: change

the infusion set every 2 to 3 days.

7. Regularly inspect the skin where you

inject to catch early signs of infection

and scarring.

You may need to adjust your insulin dose when you move to a new site. Talk to your

dietician about what dose will be right for you.
