RED-S Relative Energy Deficiency In Sport

Relative energy deficiency in sport (RED-S) describes a syndrome termed in 2014 of poor health and declining athletic performance that happens when athletes do not get enough calories through food. This can occur both as a function of poor eating habits and as a function of too intense exercise. Disordered eating includes both intentional and non-intentional under-consumption of calories.

If left untreated, it impairs almost every system in the body and can lead to irreparable damage.
