I have been taking treatment of hyperthyroidism since 2004. I was taking neomercazole till 2009. My thyroid test were fine for 3 years and stopped taking any medicine.in 2011 there were symptoms like palpitations, anxiety no weight loss when get thyroid profile checked tsh was .002 t3 & t4 normal. I visited to consultant he started methimazole 10 mg and told grave disease. Quarterly I check my thyroid profile surprisingly t3 & t4 normal but tsh have been always less than 0.007. Now the tsh 0.44 and t3 &t4 are very much in range. My weight never reduced still 80 kgs. I want to know should I continue on medication or rai ablation. I am no medication methimazole 10 mg ,betacap 20 mg.
