Eosinophilic Esophagitis Treatment: Alternative Health

Help. My teenage daughter was just diagnosed with EOE. She is about to go off to college and I am worried about her being able to eat at school. What supplements would be good for her to take. It seems like everything she eats makes her feel bad. She takes a probiotic and l-glutamine. We have tried an array of different natural supplements but not have been a great help. All the traditional doctors want to do is pump her full of steroids but I want to find the source. Her symptoms are troat pain, burning, stinging, stomach pain, fatigue, nausea. She has waves of being hungry and then nauseous. She is a distance runner and needs to eat alot of calories.
