There may be permanent loss of some or all pituitary hormones, an imbalance that can be treated with Hormone Replacement Therapy, which has been inaccurately associated with only one group of patients: post-menopausal women. HRT can replace thyroid, growth, testosterone, or adrenal hormones when those made by the pituitary to stimulate the endocrine glands are no longer produced. It can be lifesaving therapy for the many millions of patients who need to replace hormones they no longer make.
