I have an underactive thyroid, I've been on thyroxine for almost 3 years and ever since going on thyroxine I've gained weight even while trying to lose, before going on thyroxine I lost 26 kilos but have gained all that back. Has anyone tried armour thyroid?? Any success stories??

I am on the same medication and have gained as well, even though I was told I would lose. Have you had your thyroid levels checked lately?

I have and they are in normal range but still gaining heaps :(

Me too. Have you changed your diet and exercise routine?
