Can diet and working with an allergist improve my inflammation in my esophagus. i have eoe and i feel much better after changing my diet, and so don't want another painful, intrusive endoscopy?

Yes. EoE has become a much more common issue over the past few years. I see many people diagnosed with it. I do think seeing an allergist(be sure to bring the biopsy report of the endoscopy) could be helpful. Sometimes we skin test for common food triggers(or those you felt were triggers), and work on an elimination diet after seeing those results(even if negative). Feel better. Good luck.
