You mentioned that biopsies are normally taken during endoscopies. In my case, the gastro didn't see anything but took biopsies anyway.
What would he have taken a biopsy of if nothing unusual is observed? As far as you know, would he just biopsy the "most common" areas?
I'm waiting to see the Gastro on the 26th for the biopsy results and I'm a basket case. Not sure how I'll be able to make it till then.
