My 21yo daughter was diagnosed with erosive esophagitis about a month ago because she couldn t stop vomiting. She takes 2 prilosecs daily and has now lost nearly 50lbs since February. She s had ct scan, Hida scan, sugar & thyroid tests, all normal; dr thinks it s stress related. Any suggestions on any other tests we can do? Arms and legs hurt, hair is coming out in clumps, and the vomiting continues. We are getting frustrated as she doesn t want to go anywhere or do anything for fear of vomiting.
