I'm 62 and for several years I've had various symptoms which have made me wonder whether I have an underactive thyroid. Amongst these symptoms are the loss of the outer third of my eyebrows and low body temperature as taken on waking and before getting up.
I've always been fit & active - mountain walking & climbing being my main hobbies - but it's becoming increasingly more difficult to maintain these hobbies due to increasing lack of energy, tiredness etc. I realise that at my age I will start to slow down but I do think I'm much worse that I should be - I have many mountaineering friends who are my age or older and they don't have these problems.
Two lots of blood tests for thyroid activity 1 year apart were normal. GP is clearly fed up of me and won't take it any further in absence of blood test evidence.
Help! Would appreciate advice as to whether my symptoms merit further investigation and if so how to go about it. I will tackle GP again if necessary but wondered if there were any other routes I could try.
Sorry this is such a long posting - am just getting desperate
