Hi so I'm crying right now because I recently just had my first stool test and blood test for food intolerances after four years of severe IBS symptoms. I was diagnosed yesterday evening with a severe case of C Diff (to the point where I have extensive colon and intestinal damage and am on the verge
**EDIT: I should have been much more clear in my language; I don't think I'm cured of anything, I have only had my symptoms reduced to essentially nothing from where they were previously (I took tums or famotidine 1-2/day to control what I would call mild to moderate acid reflux symptoms).** **I'm v

I’ve been a 25+ year user of omeprazole 10mg daily low dose. Suffer from hiatal hernia, gastritis, GERD, etc. Even with the daily dose of my PPI, I would still get flare ups and the sensation of a ball stuck in my esophagus. It’s been a battle, a very painful one. After recent studies, I decided to
Hi, I'm suffering from gastritis and GERD for about a month, and was prescribed PPI 40mg a day. My symptoms include tight chest pain, sore throat, the feeling of lump in the throat as well as the upper stomach pain, almost like someone punched my stomach. Since I started the medication, I cut down a
I used to take famotidine regularly, and chewable tums/alka seltzer for immediate relief. I recently went on a Disney vacation where my heartburn was absolutely awful, and it was already bad before I went. My mother, whom I love dearly, unfortunately tried to get me to go gluten free for the millio

... And that famotidine and nizatidine are both on very short supply. I checked the FDA recall site and didn't see any updates besides the one yesterday about two manufacturer's recalls.
While proton pump inhibitors are generally the main line of treatment for gerd these days, I'm curious about how the h2 antagonists like ranitidine, nizatidine, etc. compare to one another in terms of side effects and the prevalence of those effects. I would appreciate any of your thoughts on this a
