After years of my IBS being in control and I've been having this new symptom off and on for some months but it's really gotten worse over the last few weeks. I was having trouble with heartburn and nausea and bitter taste in my mouth so my doctor took me off my Fosamax and put me on Prilosec. I took the Prilosec for a week but couldn't tolerate it so I went off but the heartburn is gone. So this is a good thing. But I've noticed that when I eat, particularly in the afternoon or evening my stomach gets very full feeling (fast), my stomach bloats, and then I have to run to the bathroom for loose stools. My pancreatic levels were a little elevated a few weeks ago but I don't know if that has anything to do with this. Anyway, I'm getting to the point where I'm afraid to eat anything and this is very different from my IBS or maybe it's changing I don't know.
