Hi everyone. I'm appealing to your collective knowledge to see if anyone can help. I have been taking 150mcg levothyroxine for 15 years with stable blood test results every 6 months. I had my pre op appointment for my hip replacement on 21st May. It was cancelled due to bloods - TSH was 17.4 & T4 was 11.8. I was sent to an endo who increased by dose to 200mcg which resulted in TSH 0.01 & T4 28.3! He now suggests I go back to original 150mcg but wont that just put me back to square one? I am in a lot of pain and desperately need the surgery but the consultant tells me that without a stable thyroid the anaethetist wont consider it. Any ideas?
