Hi I'm new to this board. I have had the symptoms of IBS for about a year now. Ever since I had a really bad case of food poisoning about a year ago. Since then I have exibited all the IBS symptom and they are getting worse. I have been researching alot and just today I discovered an article from Cedars Sinai Med. Center where they did a study of IBS patients and tested them for bacteria in their small intestine. After confirming the bacteria was there they treated these people with antibiotics and in 90 percent of the patients the symptoms and discomfort of IBS have gone away. I would be interested to know if anyone else thinks this could be a treatable bacteria and if your Dr. has confirmed or denied this.
