Hello @lovablesteven

Since @tiss mentioned her problem with SIBO due to the removal of the ileocecal valve, I looked up a discussion on Connect that deals with this problem. If you take a look at those discussions you will see what @tiss is talking about. Here is the link (at the top of the discussion I suggest that you click on the box and select "Newest to Oldest" in order to get the most recent discussions first) https://connect.mayoclinic.org/discussion/permanent-sibo-due-to-removal-of-ileocecal-valve/

As @tiss suggested, you might want to discuss the matter of the valve being removed next time you talk to your doctor about surgery and see if she anticipates removing that valve during surgery and how she might treat any SIBO problems.

@tiss, could you share how long you have been taking the Xifaxan? Did you start this antibiotic right after the surgery?
