After 42 years on thyroxine I found theis website and in a belief my health was the best it could be I now realise it was not. I believed the exhaustion was just something my family and I had to put up with. With knowledge from this website and using blue horizon blood test I discovered my b12 was low and my GP now gives me injections which has made a vast improvement but armed with info from this site I decided to take one more step and check my reverse t3 which I had never heard of previously. My GP keeps me over medicated on 200 mg a day, without the 200 mg my pulse drops to 50 very quickly and I feel awful. Now wondering if it's a rt3 problem but not sure what to do about it, any help would be appreciated. Results are
TSH 0.005 Range 0.27 to 4.20
T4 total 162.8 Range 64.5 to 142
Free T4 28.15 Range 12 to 22
Free T3 6.91 Range 3.1 to 6.8
R T3 53 Range 10 to 24
RT3 Ratio low 8 Range 49 to 720
B12, ferritin, vit D, etc all good and I do NOT have antibodies, my hypothyroidism is of unknown cause
