I had about 85% of my large intestine removed about 3 years ago for colonic inertia (a dead colon), and they reattached what was left of it to my small intestine (thus, no bag). I am able to have bowel movements now, though they are very irregular (vary from frequent diarrhea one day, to constipation the next couple of days, etc.). Since surgery, I have frequent gas (with bulges in my abdomen moving as the air moves through my intestines)--I must pass gas 100 times a day! As if that weren't bad enough, the smell is nothing I've ever smelled come out of a human being! It is extremely rancid, and smells similar to very rotten eggs (a sulfur-like smell). Can anybody else who's had colon surgery relate to this? What causes it, and what can be done about it?
