Asked for male, 25years old from Gorakhpur
It is normal for one or two hairs to come off with mild pull. But it is significant only if the eyebrows have significantly become thin. Your T4 and TSH is on the lower side, but not enough to start thyroxine supplementation. Keep watch for gaining excessive amount of weight even with ordinary food intake and activity or drowsiness.
Repeat thyroid panel after 6 months. You can also take up an online private consult with me for further advice.
