Regarding this new bacteria study by Dr. P, as you know my main symptom is chronic burping and bloating. I decided to travel to UCLA and spoke with Dr. Chang and Dr Ippolitti. Every doc I had ever been to has said that the burping is due to airswallowing associated with GERD. When I went to UCLA(which is one of the best GI divisions in the US), these docs told me that the airswallowing theory was nonsense. They believe that the gas is caused by bacteria feeding on carbs and fiber in the small intestine. If I understood everything they said correctly, they believe that bacterial overgrowth is secondary to a motility problem. What this means is that I have some sort of motility problem which allows the bacteria to feast and grow in numbers. They told me that antibiotics would probably stop the gas but that as soon as I went off of them, it would come right back. They did not like this treatment because it basically meant antibiotics for life. They felt that my best bet for treatment is to wait for these new drugs like zelmac that affect motility. Once the motility problem is cured, then the bacterial balance should correct itself. Does this make any sense? I am also wondering if anyone has ever tried "natural antibiotics" like olive leaf extract. I have no idea if they actually kill bacteria but if they do, it could be worth experimenting with. Has anyone ever tried it. I am curious to read more about Dr. P's study. This is very interesting. Any comments?
