Relative Energy Deficiency in Sports (RED-S)

This overview intends to show a possible diagnostic/treatment pathway for athletes with an energy deficiency. This is based on the IOC statement paper (13), which was recently revised in 2023. An interdisciplinary approach is important to reach all aspects. In order to achieve a successful treatment, it is important to involve the whole environment of the affected athlete. The earlier the intervention takes place, the less chronic consequences will occur. However, abnormalities such as primary and secondary amenorrhea, susceptibility to infection or lack of training success should always be considered as possible indications and should be subject to further examination. In addition, it is also important to recognize a current or incipient eating disorder so that professional treatment can be initiated as soon as possible with the primary goal of enabling the athlete to train and compete at the highest level.
