Autoimmune Thyroiditis can mean Hashimotos or Graves Disease among the ones that are most common. Some conditions are viral induced or can occur through a variety of reasons. I have personally injected dermal fillers (Dr Philip Young in Bellevue Washington) into many patients with Autoimmune Thyroiditis and have not had a problem. I would wait until any acute attacks are resolved and that you are in a controlled condition. But otherwise, there has not been any problems for me injecting dermal fillers, like restylane, juvederm, perlane in someone who has a history of this or other autoimmune condition that is controlled.
I hope that was interesting for you!
Thanks for reading, Dr Young
