I started looking for information about reducing antibodies a couple of years ago and found very little, nothing in the UK. But I found a Doctor who seems to know what he's talking about on the internet. This is Dr Alexander Haskell and his website is Hope for Hashimoto's - where there is a series of presentations which I found very helpful in understanding the condition. I then bought his book, which I also value. He outlines a process in the book which he believes will reduce and then eliminate the antibodes. He also believes you can then "restart" your own thyroid. I don't know how much of this is possible, but last year thinking there was nothing to lose I started to follow his plan - and when I had a private test for antobodies in February there was a slight fall for the first time, after 2 years of them climbing. I'm not advocating this or saying it works, but something is happening for me and I feel better now than I've felt for several years. The thing I like and feel confidence in is that he insists his plan must go alongside conventional medicine and taking levothyroxine is an essential part of this.
If you find a way to reduce your antibodies further please do post about it..
