I originally went to see gp because I have a goitre (and lots of other symptoms) and eventually had a thyroid antibody test done which came back over a 1000. Went to gp who put me on 100mcg levothyroxine and referred to endocrinologist.
After seeing endocrinologist who told me high antibodies was nothing to worry about and I need to reduce my dose to 50mcg. She did more bloods
TSH
