I have the same problems after antibiotics! They really mess with stomach bacteria and it takes me at least 3 months of a strict diet before it gets back to somewhat normal. Sounds like you’ve had a lot of them. I also have an

umbilical hernia that was removed once and is now back and have a Linx device for the severe gerd I’ve had. It will take about 6 weeks of bad stomach issues after going off PPI’s from the rebound effects. Sounds like you’ve had a lot of meds. Once I got off all of them feel much better but there was a lot of suffering before it got better!
