Hi. Although i have been a member since 2010 and feel I have learnt a huge amount from reading the posts this is the first time I've posted anything. I had a full thyroidectomy in 2010, ( I had multiple thyroid nodules and the surgeon made out it was a simple proceedure and I'd just need to take a hormone replacement daily. If I'd educated myself before the op rather than after i might have been a bit more cautious!) Since then have been taking 125 micrograms of levothyroxine daily and feel generally ok. However every year when i go for my bloodtest with the GP I have to fight to stop him lowering my dose as he says that my TSH is dangerously suppressed and I'm risking osteoperosis and AF. My last blood test was in September 2016 and my results were:
TSH 0.04 (0.27-4.2)
T4 19 (12-22)
My response is that i am fit and healthy at the moment and never visit the surgery other than for my annual blood test so I'd rather keep the dose as it is and am happy to live with the risk of something that may or may not happen in the future. At the moment he's agreed to leave thins as they are but i'm already starting to feel stressed at the thought of the inevitable "discussion" i'll have to have with him at my next appointment in September. They never test my T3 so I dont know how that is.
Sorry I'm rambling. My question is wouldn't all people who have had a thyroidectomy have a suppressed TSH if they have optimal levels of T4 in their body for their own needs? I no longer have a thyroid and cant make my own T4 so why would the pituitary gland need to produce TSH? Or is there something i don't understand.
i would be grateful for anything I can say to my GP to persuade him to leave well alone and not mess about with my doseage
