Late to the party. I got my initial FC1 (circa 2005) with a waiver for GERD. The waiver required an upper endoscopy every 3-5 years to keep tabs on my condition. Nearly every time required a dilatation and they'd take a biopsy. They actually ended up "retiring" my waiver even though I was "borderline" for eosinophilic esophagitis. We had a Guardsman Flight Doc who was a DO that was head of his department a local college hospital system. He was the DO who did my last 3 scopes. I was never actually diagnosed me with EE, but he said I'm headed that way. FWIW, he wasn't too concerned with a possible EE diagnosis. Hope it's a non-issue for you, but based on my experience, I'd thinks brwwg&b is probably on point.
