Is hashimotos still present after thyroid removed?

Hashimotos: The anti-TPO antibodies may still be there, but there is nothing for them to do, absent thyroid. Hashi is an autoimmune disease, and such people are susceptible to other autoimmune diseases, so the overall immune phenomena does not completely go away. Hashi and graves can overlap, and eye disease of graves can occur later, but rarely, so don't worry about it.
