Can I get a thread lift if I have an autoimmune disorder and or Hashimoto's?

I have an undiagnosed auto-immune disorder. My thyroid tests come back normal with slightly elevated antibodies. A Naturopathic Dr. has diagnosed Hashimoto's. I have had filler in my lips in the past, however the last two times the filler has balled up and settled just outside of my lip line. I've been told that I'm no longer a candidate for fillers. Would the threads differ from fillers? Could I reject them like the filler?
