I'm new here and I've been hypothyroid for 9 years (I'm 68) and my thyroxin prescription has gone from 75 mcg to begin with to 150 mcg and then reduced last summer from 125 to 100mcg. It took a long time for the thyroxine to kick in at the beginning, then I was taking too much, with palpitations etc. On 125 and on the current 100 I was/ am tired all the time, to the extent of often sleeping for several hours during the day.
My recent blood results show TSH 0.01 (0.34 - 5.60); T3 6.4 (3.80 - 6.00); T4 18.5 (7.9 - 20.00). The test results say that TSH and T3 are abnormal but my GP insists they are fine. B12 says 321 (120 - 625), folate 7.7; ferritin 25 (11 - 307). Any advice please welcome.
