But for some girls, not balancing the needs of their bodies and their sports can have major consequences. Some girls who play sports or exercise intensely are at risk for a problem called female athlete triad. Female athlete triad is a combination of three conditions: disordered eating, amenorrhea, and osteoporosis. A female athlete can have one, two, or all three parts of the triad. Most girls with female athlete triad try to lose weight as a way to improve their athletic performance.
