In april 2022, because of delayed menstruation, I got my
thyroid profile and
TSH was 0.02. My TSH antibody test and free t4 done was normal. My thyroid 99mtc scan showed reduced tracer uptake by thyroid gland. It showed 0.2%. Then after 2 months, in june 2022 , I got my TSH checked and it was 7.06. I am concerned for such a huge change in TSH level from 0.02-7.06. I have got weight gain, slightly upset stomach, hair fall, slightly disturbed menstrual cycle. I take 400 mcg of budesonide inhaler daily for asthma. What steps should I take, to bring normal range of hormone?
