Me too, had an enlarged thyroid as a young adult but function was "normal" per blood work. After baby # 3, about 10 years later, was finally diagnosed with hypothyroidism. What if a good % of PD patients are hypothyroid, seems like there has to be a connection. The other thing is the many people(including me) with the illness that are Vitamin D deficient. I wonder about that too. Also, what about the gluten connection? FG
