Hi... I'm 55 and diagnosed with Hashimoto's Disease... hypothyroidism...this is such a roller coaster ride from hell. I stand 5'7" and keep losing weight, between the thyroid and the IBS that I have. As of this morning visit to doctor, I weigh an earth shattering 108.5 Plus, I've lost over half my hair in the last 20 years. Having 3 heart attacks wasn't as much of a pain in the arse as this is.
