What Is Relative Energy Deficiency in Sport (RED-S)?
RED-S occurs when the body consistently does not take in enough energy to support both exercise and normal physiological function.
This can happen intentionally or unintentionally—and it affects both male and female athletes.
Common signs include:
• Chronic fatigue
• Recurrent injuries
• Poor recovery
• Irregular or missed menstrual cycles
• Weight loss
• Decreased performance
Over time, RED-S can impact bone health, hormones, metabolism, cardiovascular health, and overall well-being.
From a physical therapy perspective, RED-S can significantly slow healing and increase injury risk. If the underlying issue isn’t addressed, recovery can be difficult despite appropriate rehab.
