My IBS (mostly D) started 20 years ago. Just only a few years ago, I was able to bring it under control (mostly with the help of Glutamine).A few months ago I had an episode of food poisoning. Lots of diarrhea and no way to stop it for a few days. My stomach hurt. A couple of weeks later, still with a achy stomach, decided to go to the family doctor - there, I was diagnosed with Helicobacter Pylori infection (did the breath test). Was prescribed Prevpac, a common triple therapy prescription.Two days after starting the two antibiotics and proton pump inhibitor, the diarrhea was gone but not the stomach pain. Interestingly enough, I had exactly ZERO IBS symptoms. My bowels were working like never before. Those well formed stools were the most beautiful thing I had seen in a very, very long time.Went back to the family doctor and told him the stomach pain was still there. Told me to continue to take the proton pump inhibitor and see a gastroenterologist. Took the proton pump inhibitor for two months and the pain was gone. Good! Didn't go the the gastroenterologist, though.Meanwhile, I was back to my normal me, managing my IBS-D with Glutamine but not forgetting that interesting data-point, of ZERO IBS symptoms while taking the antibiotics. Did a little bit of research and ended up stumbling on Pimentel's book, "A New IBS Solution". Went to Borders, bought it and read it in 4 hours. Suddenly, things started to make sense.Decided to schedule an appointment with my long time doctor, an internist always willing to listen to patients, their concerns and even crazy theories.Now in the doctor's office, told the story above and explained Pimentel's ideas. Brought along the book and relevant Pubmed abstracts. Given my recent experience with those two antibiotics for H. Pylori, we both agreed to forgo the lactulose breath test and go directly to the antibiotics, 1200mg/day of Xifaxan.Started treatment on Nov 9. The almost immediate effect was virtually no intestinal gas. Towards the end, I was even getting a little bit constipated. At the same time, I was taking a bunch of different digestive enzymes and closely following the dietary guidelines in Pimentel's book, to avoid having undigested carbs reach the bacteria.On Nov 19 I was off the Xifaxan. I had ordered B. Infantis 35624 and started taking it. I also started taking a Jarrow's Bifido formula. I didn't want those 10 days of antibiotic use to transform themselves in years of dysbiosis. Recolonization of beneficial bacteria is a must.Following those 10 days of Xifaxan, my bowels complained 2 days ago with some gas and diarrhea but now things have improved considerably: yesterday, no diarrhea; today, no diarrhea. However, I am very well aware of the fact that it is still *WAY* too early to tell whether all of my IBS symptoms are gone for good or not. Now, for the really interesting stuff.For many years, I had had a rosacea-like skin rash on my face. I've also had a nasty 3-inch diameter skin rash right in the middle of my chest.Guess what? The rosacea-like skin rash on my face is totally gone. The skin rash in my chest is mostly gone but not completely. I'm in observation mode and looking at what might develop in the next couple of weeks.Conclusion: Got skin rashes? Have IBS? Go see your friendly doctor and take Pimentel's book with you.
