Female Athlete Triad

What is the Triad?

The Female Athlete Triad is a syndrome of: 

  • Energy Deficit/Disordered Eating
  • Menstrual Disturbances/Amenorrhea
  • Bone Loss/Osteoporosis

Female Athlete TriadFemale Athlete Triad is a serious health problem that involves disordered eating, low bone mass, and amenorrhea (cessation of the menstrual cycle) in female athletes. The condition is most common in sports that emphasize leanness, such as cross country running, gymnastics, and figure skating. In the past 25 years, much has been learned about symptoms, risk factors, causes, and treatment strategies for Female Athlete Triad. Studies involving different types of athletes have provided valuable information that has helped many physically active women avoid the health problems of this condition.

A New Model
Female Athlete Triad was first identified 25 years ago. Recently, the emergence of a new model for understanding Female Athlete Triad has greatly advanced understanding of the condition. Originally, the three components of Triad included disordered eating, low bone mass, and amenorrhea. These components are known to be interrelated, as energy deficiency associated with disordered eating plays a causal role in the development of menstrual disturbances, and both energy deficiency and a low estrogen environment associated with amenorrhea play a role in initiating bone loss. In the new Triad model, these interrelationships are reaffirmed; however, each component of Female Athlete Triad is represented as being on a continuum of severity from health to disease. At the “healthy” end of the continuums are optimal energy availability, the presence of normal ovulatory menstrual cycles, and optimal bone health. At the “unhealthy” end of the continuums are the clinical outcomes associated with each Triad component, including energy deficiency, with or without disordered eating; abnormal menstrual cycles, referred to as functional hypothalamic amenorrhea; and bone loss, the most severe cases of which are called osteoporosis.

What is triad

Another point the new model of Female Athlete Triad highlights is that many athletes may not present with the extreme ends of the continuum, but rather may display intermediate, or “subclinical,” presentations of one or more of the conditions, and, most importantly, that progression along the three continuums can occur at different rates. For example, an athlete may show signs of restrictive eating, but not meet the clinical criteria for an eating disorder. She may also display subtle menstrual disturbances, such as a change in menstrual cycle length, anovulation, or luteal phase defects, but not yet have developed amenorrhea. Likewise, she may be losing bone, but may not yet have dropped below her age-matched normal range for bone density.

While the conditions represented by each continuum can occur independent of the other two conditions, it is more likely that, because of the clear associations between the three conditions, it is likely that an athlete suffering from one element of Triad is also suffering from the others.
