I’ve a really home-made but in addition very efficient method of holding monitor of my injections so I bear in mind to rotate them.
To ensure that I do correct injection rotation, I’ve a bit of paper the place I observe down my injections (see picture beneath). I often swap from proper to left aspect every day and can begin with injecting proper above the bikini line, then swap to beneath the bikini line, and lastly inject alongside the bikini line.
This rotation sample takes me a couple of month to get by means of 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.
