when my immune system attacks my thyroid while it's producing thyroxiod i get an overabundance of it, if it gets attacked while it's not producing i don't get any.. thats the way it was explained to me.
>>4 they aren't working against each-other, one simpily limits thyroid function while the extra hormone ensures im getting the correct amount.
Also I had symptoms of both under and over activity, and my blood work would come back over for one test and under for the next...
