When I went in for my pre-op I was told that I did not carry my fat between my muscle and skin, as apparently most people do, but rather under the muscle. I was not too concerned cuz it has worked for a lot of years but wondered if te was anyone else in this situation. The only draw back is that there is no place to "hide" the port so I have an "outy'. The nurses don't need x-ray to find it.

Well the plus may be you wont have the sagging issue. since the muscle is attached to the skin instead of the fat.

Are you male? Most men do carry a lot more internally than under the skin, its women who carry more fat subcutaneously (which is why we get cellulite). But the downside to that is that its far greater cardiovascular risk since it will be all packed around your organs.
