I am 23 yrs old female, I had a history of pcod but my cysts are clear in the usg done on 10 june 2020. I am having abdominal obesity, experiencing muscle twitches. So i did my thyroid function test. My T3 result was 1.75 ng/ml and biological ref. interval was 0.80-1.81,                T4 result was 12.37 and biological ref. interval was 4.50-12.45. My results are so close to the upper limit. Kindly suggest the precautions I can take so as to lower my levels. I am expeeiencing muscle twitches and fast heartbeat/palpitations (and high pulse rate above 120 every time I checked since last 2 months. Is this due to thyroid level? Please suggest what is wrong.
