I have an appt with my primary care physician at Kaiser in one week. I have not yet been referred to a gastroenterologist by her although I have asked to be. She diagnost me with IBS one year ago based on my symptoms (no tests). Do you think that there would be more that a gastroenterologist would be able to do to help me? My primary care physician has not been helpful. My help has come from IBS books and websites, a nutritionist, exercise, accupuncture and many supplements.
