It’s possible you’ll not see proof of that scar tissue on the skin of your physique, however it’s there on the within.
The extra you inject insulin into the again of your arm, the extra scar tissue will develop there. As folks with diabetes, it’s very straightforward to get into the behavior of injecting into the identical spot time and again as a result of it’s straightforward to succeed in and comfy to entry in the midst of a restaurant, for instance.
However scar tissue will considerably have an effect on your physique’s means to soak up the insulin from that final injection, and you can find yourself needing extra insulin to do the identical job though your insulin wants didn’t change. As an alternative, it’s simply scar tissue constructed up and interfering with the absorption of your insulin dose.

I’ve a really do-it-yourself but additionally very efficient manner of maintaining observe of my injections so I keep in mind to rotate them.
To make it possible for I do correct injection rotation, I’ve a bit of paper the place I notice down my injections (see picture under). I often swap from proper to left aspect every day and can begin with injecting proper above the bikini line, then swap to under the bikini line, and lastly inject alongside the bikini line.
This rotation sample takes me a few month to get by earlier than I begin over again. To date, that has labored very well for me. I’ve no lumps and my insulin absorption continues to be actually good after 20 years with diabetes.
Lipodystrophy: a side-effect of not rotating injection websites
Lipodystrophy (LD) is a situation affecting physique fats tissue and it’s quite common in individuals who take a number of every day insulin injections.
