After asking the GP three times she said that my TSH is 9.25 range 3-4 and my T4 is 8.2 range 11-12. Although this indicates hypothyroidism my symptoms seem more like hyperthyroidism. They include heart rate 122bpm, breathlessness, feeling hot, itching, exhausted (was walking 9 miles a day now shattered after walking 1), lost in the region of 7/10lbs in weight. GP won't medicate until my TSH is 10 and also says that she is reluctant to medicate because my heart rate is high and medication will raise it further. She told me to go back in six weeks for a further blood test. I didn't fast for the last one so not sure whether it would be a good idea to do so next time. I would really appreciate any advice.
