True, the symptoms could be ampliphied from my frustration. So they can usually just see the damage during the Endo without taking a biopsy? I was not aware. I'm just tired of feeling like this with no answers. I know a lot of folks go years though.
No they usually can not see the damage visually during an endoscopy. There are often signs of inflammation but the vast majority of celiacs need a biopsy for their damage to be seen.
Hang in there. Many of us have had our problems brushed off or were told it's all in our head. I almost think it should be a sign of celiac disease. People often come around once they see you feeling and looking much better after you've been on the gluten-free diet a few months.
If all the tests come back negative, don't forget that it could be non-celiac gluten sensitivity (NCGS) which has almost all of the same symptoms as celiac disease, minus villi damage and the DH skin rash. There are a fair number of people with NCGS around here who had symptoms more severe than mine - it's not a thing to be ignored.
I hope you are feeling better soon. (hug)
