I am female and 68, I am loosing my hair. I think it might be related to my pituitary or thyroid glands. I am infertile, and was given hormones when I was 16 to start puberty. I have dry skin, high cholesterol, heavy around the waist, have dry skin, and a low basil temperature. My Thyroid levels are within range. Could I still have issues with my pituitary and if so who do I see?
