I had a total colectomy and my rectum removed, since the take-down I have had problems with liquid stool and gas.
I have noticed that I can expel an impressive amount of gas by laying in the fetal position on my knees with my head down and butt in the air and pushing gas out. Clenching my anus and releasing gas, over and over and over. It is very relieving and I feel "empty" after doing this, especially after having a large bowel movement. It is also an inconvenience as I can only do this at home, and put a towel down with a cleaning rag ready to use on the wall afterwards. Sometimes I have to do this before a BM to clear up gas pockets that may be blocking stool. If I push on/massage my stomach in this position it lets even more gas out.
However, at some point the gas should stop or ease up. It doesn't it keeps coming and keeps coming. I could pass gas almost nonstop for over an hour on command at any given time and I have before.
Is it possible, that in this position I may actually be sucking air back into my body through my anus? Think of a lung, then think of a Whoopi Cushion. It doesn't take any sort of extra muscles or movement for the Whoopi cushion to take in air after it is compressed, maybe the same is happening to my pouch? I think to myself that there is no way my body can hold that much gas. Does anyone else have this issue? Could I be sucking in air through my anus and re-passing it, creating a cycle?
