I am not on any medication for thyroid or anything else but have been diagnosed as "chronic fatigue" and over time I am physically more tired and with worse concentration. I have just got a copy of my records for the last 10 years and the thyroid blood tests are always normal - Serum TSH varies between 0.8 and 2.0 (range 0.35 - 4.94) with Serum Free T4 between 9.2 and 12.1 (range 9 - 19). I am a 60 year woman and have put on 15kg of weight in the last 12 years also (from 54kg to 69kg) even though I walk an hour a day, although this is now very slow and 10 years ago it was jogging but too tired to jog now. There is no way I can do things expected of a woman my age, like working even a few hours each day. Some days I get nowhere.
As I am on no medication I was wondering what tests I should have done so that I have a base measurement as I am hoping that there will be something that may help me get some energy back. I realise that I will have to get them done privately.
