My SO has been variably diagnosed with both eosinophilic esophagitis and GERD over the last 15 years. First they thought it was GERD, then EE, and as of his most recent endoscopy, his doctor now thinks it's both GERD and EE. His case is peculiar in that he suffers none of the regular pain that is often associated with GERD; rather, every year or so food will get completely lodged in his esophagus and will need to be dislodged at the hospital. Endoscopies have been happening ever 2-3 years as a result. His doctors have had him on PPIs for the last 15 years, and only one has even mentioned an anti-allergenic dietary intervention, but only to note that "no one can follow it".
I have suggested that he try a paleo diet, but he is resistant to the idea because he says that there is no way to prove that it's working, short of an endoscopy after about a year on the diet. This is because, as I mentioned above, he doesn't feel anything like the regular heartburn of GERD. He is also skeptical because 1) he gets a stomach ache any time he eats vegetables (I believe this is due to years of suppressed stomach acid) and 2) his doctors have never suggested anything like a paleo diet, which I think is merely the culture of our current medical system.
So, does anyone have any suggestions for how to measure the efficacy of paleo with respect to GERD/EE?
