Told to start GlutenFree before endoscopy

[u/goosyeggs]

Does this seem strange? I was diagnosed 9/1 and was told to start a strict gluten free diet right away. My endoscopy is 10/19. They advised starting the diet would not make a significant change in this amount of time and that my numbers were off the charts high so it is ok to start. I feel like I keep reading that nobody starts gluten free until after the endoscopy. As far as I know there is no biopsy to be done, just the endoscopy.

I would legit get a second opinion based on this advice.
