Hi, My son has EE. My son got sick when he was 10 months old and we got our diagnosis when he was 22 months old. EE is a very specialized disease and most physicians don't know how to treat it appropriately. Most families have to travel for treatment. The top facilities are Cincinatti Childrens and Children's Hospital of Pennsylvania in Philly. Be careful with who you see, it's a bit of a long haul after diagnosis.
I would recommend you go to apfed.org or cured.org and get more info. Both sites have tons of info. The EE community is pretty tight knit....the moms bond together strongly.
If you say that you just got a diagnosis, I'm guessing that you got a scope with positive biopsy results. If so, your next step is to get the three types of allergy testing. Your son will have RAST testing (blood), prick testing (traditional dermal testing) but he also has to have something called patch testing. Make sure that the patch testing is done by someone with expertise in this field.
If you are lucky, you will get some positive results to this testing. If you do, the doctors will have you eliminate all of those foods from your son's diet and will then re-scope to see what the results are. If there are no conclusive results, they usually do an elimination diet where they will eliminate the most common allergy foods....soy, wheat, milk, eggs, peanuts, shellfish, and a couple of others. The other thing they may do is to pull all food, but that's usually a step down the road a bit. It sounds awful, but it gets better.
My son currently has eliminated all beef, chicken, turkey, eggs, milk, tree nuts, peanuts, peas, pears, bananas and chocolate from his diet. He drinks a special formula to get his nutrients. He's a happy, healthy looking five year old.
I'm not going to lie and say that it isn't overwhelming, it is. Some days are good days and some bad. There are lots of other families out there who are going through the same thing. Facebook has several support pages. Good luck!
