Hi everyone. Im due to have a lower neck lift under general aneastecic . But my TSH is 0.34 . Normal range is 0.50 to 4.00 . But my t4 is normal . Im waiting to hear if they will still operate , with my thyroid being low in TSH. does anyone know if its risky to go under a general anestecic. (Sorry for spelling ) with my thyroid level ??
