When I stick my stomach out a little, I notice there is a little bit more of a pouch on the right side than the left. Not noticeable with clothes on, if so, barely noticeable. It is soft, feels just like the rest of my stomach. I have had multiple abdominal palpitations by physicians recently and no one has said anything. I had a colonoscopy and have a tumor in my rectum so no relation. It isn't a huge difference at all and only noticeable depending how i stand. It isn't noticeable laying down.
