Will a gastric bypass help ibs?

Gastric bypass IBS: Generally not. In my experience, gastric bypass does not seem to have any effect on ibs, and patients usually continue to have ibs symptoms after surgery.

No ...: Gastric Bypass is a surgical treatment indicated for severe obesity causing secondary health complications. Irritable bowel Syndrome (IBS) is characterised by abdominal pain / bloating with bouts of constipation or diarrhoea. It is probably caused by the interaction of certain foodstuffs on somewhat sensitive and overactive intestines. Bypass Surgery is not indicated for IBS and will not help.

It is unpredictable: It is not really predictable, some get better others get worse. I typically recommend my patient with significant IBS to consider sleeve because of confusion otherwise IBS symptoms can cause in post operative period. Any abdominal pain after gastric bypass should be taken seriously and if one is having pain because of IBS then it is hard to assess unless expensive tests are done every time.
