The position of the pump can influence the effectiveness of the flow of the insulin into our bodies. Here is the article from Diabetes Health.


I gather from this that the flow is best when the pump is located on the body above the tubing, so the insulin is flowing downward. It is poorest when the pump is below the tubing and the insulin is flowing upward. That explains why i get lower BG numbers when my pump is on my belt and the site is on my lower ab or legs. The insulin is always flowing downward in those situations. If my pump was on my belt and my site was on my upper ab, above my belt, then the flow would be less effective since it would travel in an upward direction.

That was interesting…is that going to be the same with ALL insulin pumps? I may have to try to change my position and see what happens with mine. I did not notice though they tested Animas insulin pumps though. I could see though in another since where they are coming from. If you look at how and I.V. is placed or a individual with a g-tube, it does make since. why would a pump be any different. I'll have to try to use this in something with my nursing term papers or something. Interesting information!!!

Where are some places besides the belly I can place my insulin pump. I am trying a new place again and seeing but I am not quiet sure. I can not believe I am asking this, since I have been on my pump for almost 4 years now. It has been belly and hip but someone was saying try my inner thigh? I want open up my options better.

I rotate between my abdomen and my upper legs to avoid scar tissue. Using the same body part too long can cause scarring beneath the skin surface. That can lead to poor absorption and high blood sugar.

Some people use their upper buttocks, hips and love handles. I am a restless sleeper and would rub the site against the mattress too much so I will stick to my abdomen and tops of my upper legs. I am avoiding sides and thighs. and any places that would rub against the bed.

I read about two women who say they sometimes use parts of their breasts.

Hey Roshy! I use the MM 522 and would not ever use my arms because they are mostly lean and do not have enough fatty tissue for me to have good absorption of the insulin. I have seen men and women post that they use their arms and have good results. I assume they must have more fatty tissue than I do. I have also seen a couple of women say they have used their breasts for alternate sites for their infusion sets.
