Symptoms of RED-S.
Relative energy deficiency in sport (RED-S)[1][2] is a syndrome in which disordered eating (or low energy availability),[3]amenorrhoea/oligomenorrhoea (in women), and decreased bone mineral density (osteoporosis and osteopenia) are present.[4] It is caused by eating too little food to support the amount of energy being expended by an athlete, often at the urging of a coach or other authority figure who believes that athletes are more likely to win competitions when they have an extremely lean body type. RED-S is a serious illness with lifelong health consequences and can potentially be fatal.[5]
RED-S is the broader, more comprehensive name for what was formerly known as the female athlete triad (or simply the triad), which was a condition seen in females participating in sports that emphasize leanness or low body weight.[1][6] As the non-menstrual components are also seen in males, the name was changed to the comprehensive term RED-S.[1]
