Hi, I am asking this for my sister. She has a 2 year old daughter that has seen several doctors and still no relevant answers that help. She has been experiencing abdominal pains, severe fatigue, loss of appetite, loss of weight, and vomiting pretty much every time she eats. They have told my sister that my niece has kidney reflux and she is on medication but nothing is helping at all. My sister and I have done countless amts of research on our own trying to figure this out. My niece has an appointment at U of M hospital in July. Please, can you possibly tell us what things to look for because she is afraid she won't get a good diagnosis on this?
