Patient: I’ve been suffering from hyperthyroidism for one year and two months. From September last year to February this year, all three of my thyroid tests were normal. The TSH level was elevated again today (above normal) and the ultrasound showed (compared to a year ago) that the transverse diameters of the left and right lobes of the thyroid gland have become larger. The anterior and posterior diameters of the left lobe have decreased by less than 3mm, and the anterior and posterior diameters of the right lobe have increased. I want to know if my condition is Hashimoto’s hyperthyroidism. If I am not sure, what tests should I do or how can I be sure? And can Hashimoto’s hyperthyroidism be cured? Will it turn into hypothyroidism later? If it is hypothyroidism, do I have to take medication for life? Will it affect fertility? Can I get pregnant? Jia Hongli: The results of your test cannot determine whether it is Hashimoto’s hyperthyroidism. The following tests should be done: FT3, FT4, TSH, TPOAB, TRAB, and iodine uptake rate, which should be checked in nuclear medicine. In case of Hashimoto’s hyperthyroidism, it can be completely cured with 131I treatment. Hashimoto’s hyperthyroidism is prone to hypothyroidism, and after hypothyroidism occurs, you need to take Eugenol for life, which does not affect your fertility.
