Ms Adam, it is important to have your symptoms diagnosed by a medical practitioner or doctor or a gastroenterologist. You cannot self diagnose IBS and there are many serious conditions that mimic IBS. So I would go back to him or another doctor and they will probably need to do tests.These are ten really good questions to take with you. http://www.AboutDigestion.com/script/main/...rticlekey=13683 I would also give up the coke for a couple weeks or for good and try to lower your stress levels.If that doctor is not giving you the attension you need find another doctor who can work with you or have him refer you to a gastroenterolgist.
