I was diagnosed with IBS in the past. Nothing prescribed nor any dietary adjustment has helped. Recently hospitalized with another illness, I was put on a ventillator. I was given Protonix, I assume, to help prevent esophogeal erosion from stomach acid and breathing tube. Anyway, the Protonix has cured my IBS. I had not had a normal BM in years. Now my bowels are finally becoming normal again. It makes me wonder if maybe I had H-Pylori instead of IBS? Many of my "IBS" symptoms were the same as with H-Pylori. Is Protonix used to treat that?? What is the treatment dosage and regimen?
