Can this be because of hypothyroidism? Thanks.
You can certainly have symptoms, over five is pretty high considering that under 2 is normal! Please find a doctor who takes you seriously.
Low iron can cause thyroid conversion issues. Hopefully they checked all your iron levels. When they checked folate, did they check MTHFR? If they didn't, and you're a carrier or have the mutation, taking regular folate is not good for you. If you're a carrier or have MTHFR, you need to be taking methylfolate. Low folate can cause similar hypo symptoms. A brand name of methylfolate is Deplin, it's advertised as a 'brain food'. I was put on it before I was diagnosed with Hashimoto's. I could definitely tell the difference when I started taking it.

One other thing, were you gluten free before being tested? If you were, the antibodies may be in the normal range.
No !! But u need to get folate and iron levels up so u will feel better!!
