What is RED-S?

RED-S stands for Relative Energy Deficiency in Sport and is exactly what the name implies: a shortage of energy available to keep up with the demands of exercise, on top of essential daily functions. When the delicate balance between energy intake and expenditure is tipped in the direction of low energy availability over a period of time, it can negatively affect almost every system in the body. This incredibly common issue among male and female exercisers can carry serious health and performance consequences. As an athlete, or someone who supports one in any capacity, we recommend getting to grips with the signs and symptoms, alongside common causes, and how you can play your part in prevention.
