I think I have read that people develop hyperthyroidism w/ MG.
I have had controlled hypothyroidism for years with 200mcg of levothyroxin.
My last two checks have been July at .3 and may at .9 (goal is 2).
could MG cause the fluctuation.

My DR. made an adjustment on my med to 175mcg today to get it back to a good level.

I had a positive modulating ACHr test and one negative. I was wondering if the thyroid change would be a further indicator of MG. Any thoughts?
