Dr. Ray Peat said:"If your thyroid is working efficiently, your pituitary doesn't have much to do and you're not likely to get a pituitary tumor, your adrenals don't have much to do, and your ovaries don't get over stimulated. The other glands have an easy job when your thyroid is working right. If your thyroid gets interfered with, you have to rev up your adrenals and your pituitary becomes commander in chief and tells everyone what to do."
