For those of us who inject insulin, it can become very much part of our everyday lives – just one more thing we have to do before we eat. (Dish up, calculate the carb count, inject, and then eat!) It’s easy to fall into a bad habit of injecting into the same area every time we eat, but rotating injection sites is really important. Do you know how often you should rotate your injection sites? Here’s all you need to know.
Why rotating injection sites is important
It’s important to inject into different places in your body so that the injection sites have time to heal. If you inject into the same area over and over, it can lead to lumps and mounds under the skin known as lipohypertrophy. By rotating where you inject, you can inject into the same spot as little as possible.
The most common places to inject are in the stomach (abdomen) area, upper thighs, arms and top of the butt. Whichever you choose, divide the area into sections and inject into one section per week – but always one finger width away from the last injection. If you use the Zone System, you can divide the abdomen into 4 zones, the thighs into 2 zones, the butt into 2 zones and the arm into 2 zones. One zone can be used for one week, before moving on to the next zone
It’s important to use large, multiple injection areas so that you don’t repeatedly inject into the same spot. If you rotate zones, there will be plenty of time for your body to heal before the next round of injections into that zone.
The end goal, of course, is for insulin to be absorbed properly and blood glucose to be as stable as possible. The right injection technique can be a big help in this regard, as it ensures you’re not developing lipohypertrophy.
