What is the deal with the belly button and shots/infusion sites?

I’ve read in many places that shots (and infusion sites) should not get more than a couple of inches away from the belly button.

I am sure I saw it somewhere, but I honestly don’t remember why this is important.

Can someone shed some light on this?

I have never heard of this before, but… a couple of infusion sites ago, I did put a site close to the belly button and had the worst numbers ever and had to change my site ASAP.

I am thinking absorption issues.

I thought it was the opposite: that you should inject at least a couple of inches away from the belly button.

The tissue within 2" of the belly button is tougher than the rest of the tissue on your abdomen. So the absorption rate will be quite different and unpredictable.

Ahhhh the tough belly rule.

Ah - so that is why! I have wondered too, but Manny thought to ask! Thank you both of you.

You are right. I wrote it incorrectly. :S

Well, I’ve never seen any formal explanation, but I have generated some horrible big black bruises that took a long time to heal by injecting a bit too far away from the belly button. So maybe it is that the vasculature changes there.
