Hi, everyone. I'm just wondering if having an under active thyroid or hashimotos a life long condition? My son who is 13 in a few ekes has been diagnosed by our G.P as having an underactive thyroid ( very low, according to our G.P ) and further blood tests show he has raised antibodies in his blood. He is seeing a specialist at Alder Hey in 2weeks but hasn't been pit on any medication by our G.P and has only had 1 lot of blood tests by our G.P which were done on the 12th of June this year. Do you think I should get our G.P to do another lot of blood tests beofre we go to see the specialist on the 18th of September? Any advice would be great! Am just worried that if we see the specialist he won't put him on any treatment straight away because he will want to do more blood tests!
