I am one of the 5% who experienced postpartum thyroid issues. I see a natural/conventional doctor who has me on Armour Thyroid as opposed to Synthroid. I feel better at least knowing it's less synthetic (comes from dessicated pig thyroid). It's true thyroid issues usually accompany other autoimmune problems. I experience Raynaud's syndrome, mild psoriasis and adrenal fatigue. I have to say since going Primal that everything has leveled off a bit. My skin and energy are better, and I'm curious to see what my next blood test reveals. I don't expect to ever be rid of my hypothyroid but I do feel this lifestyle is helping me manage it.
