Is there a way to help my boyfriend understand my ibs?

Diet and fluids: I rarely prescribe meds for ibs. In my experience teaching people to eat and drink properly resolves most if not all symptoms when the patient is compliant and follows through. Hi fiber, 80-100 ounces non caffeine, non alcoholic beverages each day, regular meal times, excercise. Consistency is the key to being symptom free. Get him to respect your eating habits and follow with you.
