Personally I would call the place and see if with more information regarding her clinical picture they would bump her or overbook their provider to be seen.

It’s most likely the referral being out that far is bc the specialists are very booked. Is she losing weight? She has to become more “critical” for her to get bumped on the schedule. Otherwise unfortunately she has to wait. Unless she can call other GI specialists further away….and is willing to drive. Good luck.
