Hi Im new here, and I thought id pass on what ive been looking into regarding the thyroid. Apparently its a bit of a scandal, theres a patient movement and a bunch of endocrinologists backing them up, over under-treated thyroid patients. Apparently you can treat hashis before the labs are out, you may be one of those that require t3, if t3 makes you hyper it can be a cortisol or iron stores issue... etc... its more complex than most endos think. you can read it at stop the thyroid madness. Its really worth digging around that site and trying what works for those patients imho.
