@alex936 She was 2 months old when we adopted her. During that first 2 months they changed her formula several times. A week after we took her home, she had bloody diarrhea. The pediatrician tried dried beef formula, and something else weird. Finally he put her on pears, rice, and lamb. She ate like a little pig and thrived. At the time we had no idea that this beginning was going to be a lifelong issue. She takes a Xolair injection every 3 weeks to hold down hives. She has had allergies and sinus issues her whole life. That may or may not have to do with mast cell. In junior high school she had a months long case of Epstein Barr virus. Missed almost that whole semester. She is 50 now, and can eat about anything she wants. But she usually eats very little at night. I guess it's like she lets her gut rest. Even after diagnosis, she had a hard time finding a doctor who knew what to do with her. She was diagnosed states away from where she lived. At one time she was on 3 meds for anxiety, etc. I guess they thought she was a hypochondriac and needed to calm down. Two were habit forming, and she took herself off by tapering down. She felt much better when she got off that. She has mast cell activation, POTS, and Ehlers Danlos. Fortunately the ED does not give her problems. The mast cell is what messes with the gut. She was diagnosed about 6 years ago. The gastro doctors knew nothing about mast cell. Some may have learned about it since she was trying to find treatment. Hope this helps. Let me know if there is something else. Gloria

@alex936 I forgot one thing. When she was a year old the doctor suggested that we give her eggs. She took one bite, gagged, and a red spot popped up on her face. So she has been reactive all her life. She can eat just fine today.
