Thanks for the suggestion. I have an appointment with my GI coming up soon and I'll definitely ask her about those. Dupixent in particular looks very promising!
I'm glad you got your daughter into treatment early. I'm ~30 years old and research and treatments for EoE weren't nearly as good when I was her age, so I wasn't properly diagnosed until my 20s. By that point, just eating normal meals was a struggle and I had to have an esophageal dilation before I finally got onto my current treatment plan. I hope she never has to experience that, it sucks.
Omeprazole and elimination diet work ok for me, but it's not anything close to remission. I can finally eat normally again, but I don't have a comprehensive list of my trigger foods, and I get painful flare-ups if I accidentally eat the wrong thing. I'll gladly give myself injections once per week for the rest of my life if it means no more intermittent chest pain and it lets me eat a normal cake on my birthday again.
