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
Still so surreal. I was just another sub member for years, trying everything under the sun for GERD and slowly losing hope. Till I had none. Like many of you, I went through the whole gauntlet - endless tests, endoscopies, pH tests, you name it. When surgery finally became my only option, I was unea
Hi everyone, Just wanted to share something I wish I'd known earlier: I was on esomeprazole (40mg daily) for over 15 years. No one warned me about long-term side effects, especially around nutrient absorption. Over time I developed severe fatigue, brain fog, and eventually iron deficiency anaemia.
Summary of my experience as some tips for LPR sufferers!!! Hey everyone I just came back from my ENT and I finally got diagnosed with LPR!!! It’s been months of me trying to get a doctor to believe me and finally, and ENT at Brigham and women’s hospital in boston Massachusetts diagnosed me. Her name
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

I’ve had GERD since I was in my teens, but when omeprazole became available, I thought it was behind me. No more chewing handfuls of Tums; no more heartburn. Then, about six months ago, I started having difficulty swallowing. I told my doctor about it, and she got me an appointment with a gastroente
If you take omeprazole, Nexium, pantoprazole, or any PPI long-term, there are 5 nutrients being depleted. Most people who supplement don't realize the FORM of the supplement matters even more when you're on a PPI — because your stomach acid is suppressed. Here's what the research shows: \*\*1. Magne
Most people don’t come back to talk about how they treated GERD once they heal, so here’s my experience,hope it helps someone similar. (**P.S**.: Every case is different. Listen to your body and try what works for **YOU**!) I suffered from GERD for 3 years with extreme daily burns. It started way
I have spent the past few days on vacation in Mexico (Cancun) at an all-inclusive resort. I knew going in that I was gonna be pretty gluttonous because access to multiple restaurants 24/7 is fun. I also knew this would lead to some pretty intense heartburn, so I packed extra Omeprazole, Tums, and Al
For the sake of your health, get an endoscopy done. Here is the story of my journey; please read the TLDR if you don’t have patience. (List of symptoms at the bottom.) I’m a 26-year-old male, moderately athletic. I’ve struggled with health anxiety (mainly concerning my heart) for the past two years
I’ve been in this sub for a long time. I (45M) have suffered with GERD for 15 years. I’ve been on Omeprazole 10MG - 20MG for 15 years. I was finally tired of having to take a pill to live and wanted to try and fix this. Important to note that I worked with my GI doctor as I went through this process
TL/DR: after months of constant evaluation I was started on Enteragam and have had amazing results Earlier this year I posted a number of times hopelessly on here feeling extremely depressed at the severity of my bowel issues. I had chronic diarrhea on average 20+ times a day. Most mornings I spent
Hi everyone, I'm making this post to share my journey over the years with this disease we all know and hate: GERD. I'll share everything, but I’ll try to keep it as short as possible. It all started back in 2020, just a few days before the COVID lockdown. I went to one of my best friend's birthday
