I have a somewhat similar experience. I have been gluten light for well over a year, because I have figured out on my own I felt better when I did not eat it. With continuing gastrointestinal problems, I went to the doctor. I was only tested for celiac via a biopsy from a scope, as the doctor did not expect I would have celiac, but figured she may as well...
I was diagnosed with celiac just over a month ago and have been off gluten ever since. In a number of ways, I already feel much better. However, I seem to be growing more and more exhausted. Has anyone else experienced this in the early stages of being off gluten? Thanks for your input!
