Does High Dose Of Synthroid Cause Hair Loss?

i have been on synthroid for years same dose, recently I started working out and have lost about 20 lbs since March. Over the past few weeks, I noticed I am losing a lot of hair. I can see areas of thinning. My question... could I be overmedicated and not need as much synthroid, and if so, would that cause my hair loss?

Hello.The hair loss may be related to excess intake of Levothyroxine.
It is necessary to make a measurement of thyroid hormones in blood
(T4 and TSH).Please,go to your doctor to request blood analysis.
I wish you good health.
