When my boyfriend was young, he would throw up no matter what he ate. The only thing that helped was eating buns. After a while he started finding a few foods that he can eat: pizza, chicken nuggets, fries, breaded tilapia, chicken soup, potato pancakes, Kinder chocolate. He says that anything else makes him throw up. Recently I've been trying to help him try new foods but I'm getting frustrated at the lack of improvement. Is this something that can be helped, or is it actually a disease? I can't find anything no matter what I search, and he says that doctors have never had an answer for him. Please help!
