My daughter, that is 20, has bloating, gas, burning diarrhea, with abdominal cramps after she eats. It can be immediate or up to 4-5 hours later. She went to GI and they found nothing in her blood work and a test that she blew into a bag. The allergist denied food allergies, and the PCP cleared her for her all of blood work. She was completely healthy until about 2 years ago when this all started. She stopped eating all dairy and eggs with no relief. It seems to be getting worse and we are not sure what avenue to do next. She feels horribly digestive wise with no relief. She is active, healthy otherwise, does Yoga 4-5 days a week, is in college, and weighs about 125 pounds. She also is a vegetarian and has been for many years.
