I have Crohn's disease since 1973
once I had surgery the Doctor told me my bowel will never be the same.
Obviously avoid foods you know are gassy- as broccoli, pizza, etc or minimize them
drinks lots of water before, during and after meals at least 68 oz per day
which helps with lactic acid which causes gas. charcoal pills sold in a pharmacy must be careful not taking them the same as other meds, they absorb the gas- sold in any pharmacy- you may need 12 but works great before a party or date. this is a very difficult issue and one needs to focus on the fact that 90% of the time it is ok and the small amount
which it is not will pass. no pun intended. we need to make the best of a bad situation
