Can an under active thyroid get better? I stopped taking meds after 4 years. Blood test came back normal! did it heal? No more meds?

Can an under active thyroid get better? I stopped taking meds after 4 years. Blood test came back normal! did it heal? No more meds?

If you had subacute thyroiditis, you could be transiently hypo and then recover completely. If you had hashimotos, you can have a flair, and then recover, but you will likely become permanently hypo eventually. Don't assume you are permanently better; good follow up. ...Read more
