H-Pylori is a nasty bacteria. I had an upper GI done earlier this year and they took several biopsies, found out I had it! Know this, it DOES cause cancer! They put you on a triple antibiotic therapy...14 pills a day for 10 days...ugggh! I still have major stomach probs and had another upper GI about 2 mths ago, more biopsies, but thank God the H-Pylori hadn't come back. I'm on Zegerid now after trying many different drugs. Most times it does help with the major acid/nausea. Anyway, hope this helps.
