Relative energy deficiency in sport (RED-S) is a syndrome in which disordered eating (or low energy availability), amenorrhoea/oligomenorrhoea (in women), and decreased bone mineral density (osteoporosis and osteopenia) are present. 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.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. As the non-menstrual components are also seen in males, the name was changed to the comprehensive term RED-S. Classification
Formerly known as the female athlete triad, RED-S is a syndrome of three interrelated conditions. Thus, if an athlete is suffering from one element of the triad, it is likely that they are suffering from the other two components of the triad as well.With the increase in female participation in sports, the incidence of a triad of disorders particular to women—the female athlete triad—has also increased. The female athlete triad and its relationship with athletics was identified in the 1980s as the prevalence increased during this period, and symptoms, risk factors, causes, and treatments were studied in depth and their relatedness evaluated.
Posterior amorphous corneal dystrophy (PACD) is a rare form of corneal dystrophy. It is not yet linked to any chromosomal locus. The first report describing this dystrophy dates back to 1977. References
