Patient: My mother is 50 years old and has been suffering from thyroid disease for 10 years. On the advice of her doctor, she underwent bilateral thyroid nodule removal on March 1, 2012. -(14.1) Triiodothyronine (T3) 1.18 (0.8-2) The TSH value measured several times before discharge was also extremely low, so the doctor ordered not to take eugenol for the time being, but the TSH value measured one month later was still very low. I was treated with nuclear radiation at Jinzhou 205 Hospital with good results, and then I considered surgery because of the enlarged nodules. Now I don’t know if the surgery has caused hypothyroidism or hyperthyroidism, and if I need to take any medication. I hope you can give me some treatment advice with your rich experience, and help me to be very anxious. Jia Hongli: Did you have hyperthyroidism before the surgery? If you have hyperthyroidism, you can still have hyperthyroidism after surgery. low TSH, FT3, FT4 (not T3/T4 which affects too many factors, not allowed.) Normal, subclinical hyperthyroidism, continue to observe the nail function, just once every 2-3 months, no medication. If there is no hyperthyroidism and TSH never rises, it is recommended to do a cranial MR to see if there is a pituitary lesion.
