Sorry you are dealing with SIBO. I have been there but that was prior to my experience with PMR. I have no doubt that the SIBO was and is a result of PPIs and H2 -blockers (fomatadine). Gastro and family practice doctors throw this around like it is not a powerful drug. It is! It is even sold over the counter in the US. Just crazy. If you have any doubt or have yet to get an exact diagnosis from a Dr about SIBO, you can get a breath test done to confirm. There are natural remedies for SIBO in addition to heavy duty antibiotics. PPIs for more than two weeks (some say 6 weeks) can really do a number on one's digestion.

I totally disagree that this is an effect from Kevzara. Digestive issues even without taking a PPI are notoriously common with long term prednisone treatment. Sounds like some sort of stomach and/or bowel issue is going on and that can be a difficult one to treat and diagnose. I suggest something soothing such as GI-Fortify by Pure Encapsulations in the mean time. Self treatment can be a good way to go while looking into more complex issues such as ulcers, gastritis, different types of IBS, etc with the doctors. Imaging such as you are getting (a CT scan, you mentioned) and an endoscope (and colonoscopy) are worthy procedures to rule out issues that are more sinister and not simply and upset of the microbiome and/or the gut mucosa. Gut lining or mucosa are very susceptible to NSAIDS, of course, but also prednisone. It can take a while to heal the gut but that is the "joy" (??) of PMR, you get to deal with more issues after you have dealt with PMR. Good luck.
