This problem is seriously affecting my day to day quality of life... I knew that gastric bypass can cause flatulence problem but mine is way over the top.. I think I have tried everything I can try and couldn't solve this problem. I've increased my probiotic intake, used charcoal pills, simeticone, changing diet, herbal teas.... I've tried it all and with no success.. and it's not only the problem of trapped gas that I have but that my farts smell so awful that I sometimes cry from embarrassment that it causes me in public or between family and friends.. I'm in desperate need of help..

The smell is more common of an issue with bypass because of the amount of food that is not fully digested. Same reason BM's are so foul. As for the amount of gas, the best thing to do is lots of walking and slow methodical chewing when eating. The less air you swallow, the better.

I'm coming up on 2 years post op and the time that I've had foul smelling farts and BM is when overeating especially sugar and fat. Is there anyway you're eating crappy foods. And I've never heard of having undigested food causing issues. I also take a supplement called Triphala and it's good for digestion but if you overeat sugar or drink sugar full drinks your farts will stink!! Cause your body is dumping sugar. If you're still early in healing process under 5 months then it can just be the healing process but still avoid junk food.

I don't know how far out your are from surgery,but it gets better as your body adjusts.Eating sugar and fats will make it worst.So stay clear,not on our diet plan anyway.

If you eat a lot of meat, maybe papaya enzyme could help? Apparently, after surgery, some people can't digest meat well enough? Ask your physician about it, maybe?

Also, in another post, you mentioned light colored stools, that is a symptom of gallbladder disease. But, from experience, that's a painful condition, so, you'd have felt the pain.
