I've had four annual endoscopies. The first three showed NO improvement -- the last finally showed minor improvement -- I went undiagnosed for decades, but my celiac doctor was surprised by what he saw each year.
How does your aunt feel?
Has she had a subsequent celiac antibody panel to make sure she isn't accidentally ingesting gluten - this can happen sometimes with medications, etc.
Have her symptoms improved? If so, I wouldn't worry about the damage for now -- stay as gluten-free as possible in this world and have another endoscopy after another year or more of healing.
thank you for the reply. my aunt had diarrhea all the time and after going gluten free for only weeks thw diarrhea went away and sje started gaining weight which she was never able to do. her follow up blood work is all normal
