Thanks BW, i was afraid someone would say that about PCOS - i'm a recovering sugar addict. I suspect my thryroid was slow for a long time before it was diagnosed (i was kind of chunkier/tired then too) and i got into the bad habit of eating sugar for the "lift". I try to avoid so much refined sugar now but i LOVE my carbs it's true.... I need to do some research there.

Thanks WA_Endo, my sister is actually my half-sister, my mother's other daughter, so we're ONLY related through my mum. As i said, as such i never really thought i would suffer her problems until i got Hashimoto's, then i suddenly realised that my healthy lifestyle could only do so much to counteract genetics.

My Hashimoto's seems to hae come on when my sister's did - in our early-mid twenties (she's 16 years my senior), and i guess one ray of hope for me is that she's had PCOS and endo since she was still in puberty, so perhaps i have escaped them? I just think i'm lucky to know my chances are higher and should do something more than wait and see, if you get me. I already have a daughter, but her father and i are no longer together and i guess i want to be able to protect my fertility in case it is another decade before DP wants to start a family.

Thanks again for your advice, i knew you lot would know!
