How Can Hair Loss Along With Acne On The Face And Chest Be Treated?

Has had stomach issues for 5 years. Hair thinning, breakout on face chest and stomach of which look like pimples but stay infected and puss like for days. Anything she eats shes throws up but not before belching for about a half hour along with her stomach flares up. Thought once daughters gallbladder was out it would fix all the problems. She was ok for two weeks and now its starting up all over again. she will most likely be in and out of the hospital again as she just was the other day. She now is experiencing some blurred vision and when she is on ice skating her equalibreium if off. I wonder is it and enzyeme definciency? I am at a loss and she has seen so many different doctors but she still continues to have issues and I worry she is not getting good nutrition due to the issues.
