Diagnosed 5 years ago after a couple of late miscarriages and lots of hassling of GPs. It's a weird one, flaring up every so often. Sometimes GP says I no longer need Levothyroxine, then when I have a flare-up it takes a month or so to get the GP appointments and blood tests sorted, by which time my neck is huge, I feel horrendous and have stacked on the weight.
I've recently been reading about the effects of gluten on Hashimoto's, as they reckon one AI disease can sometimes lead to another. I have to say, since cutting out gluten, my symptoms have all but vanished... I'm currently on 25mg Levothyroxine, and feel amazing. Fingers crossed it lasts!
