In this article, we will talk about the most common disorders, anorexia nervosa and bulima nervosa. For athletes it is important to know that disordered eating, amenorrhea, and osteoporosis are all part of the Female Athlete Triad. The lack of nourishment caused by disordered eating might result in the loss of many or more periods in a row. This, in turn, causes calcium and bone loss, putting the athlete at a far higher risk of stress fractures. Each of these conditions is a medical issue. They create serious health risks that could be fatal when combined. While any female athlete can develop the triad, adolescent females are particularly vulnerable due to active biological changes and growth spurts, peer and societal pressures, and rapidly changing life circumstances that accompany adolescence.
