The female athlete triad, a syndrome of disordered eating, amenorrhea, and osteoporosis, is now clearly recognized in selected populations of elite athletes. It is often seen in the sports that have an emphasis on “thinness,” including gymnastics, figure skating, and ballet. Components of the triad are linked pathophysiologically, leading to significant morbidity and, on occasion, mortality. The disorder is difficult to treat and requires a multidisciplinary approach with intense psychological counseling as the primary focus of attack.
