Missing period? If you’re exercising a lot, this may be why
Are you missing your period, feeling fatigued and not recovering as you usually do? You may be experiencing a syndrome known as RED-S.
What is RED-S
RED-S is a syndrome affecting athletes whose energy output through exercise and activity is greater than their energy input through diet.
The abbreviation RED-S stands for:
Relative
Energy
Deficiency In
Sport
Sometimes referred to as Low Energy Availability (LEA), RED-S can have a wide range of potential health consequences, effecting many parts of the body including:
- altered metabolic function
- menstrual changes in female athletes
- decreased muscle strength
- impaired bone health
- anaemia
- irritability and reduced concentration
- increased risk of illness and injury
Signs and Symptoms
It is important the red flags of RED-S are detected early to maintain and improve performance and prevent long term health outcomes. This may be challenging as symptoms can often be subtle however, athletes participating in sports with weight categories or an emphasis on aesthetics and appearance are at higher risk. Signs and Symptoms can psychological, behavioural, physiological or performance related and may include the following:
Psychological: perfectionist mindset, anxiety around food and exercise, social withdrawal due to fear of missing out on training, feeling that only weight and performance can define you.
Physiological: Lack of three consecutive periods or changes to a previously regular menstrual cycle in female athletes, decline in morning erectile function in male athletes, always cold, digestive issues such as constipation and diarrhoea, poor training adaptations and results.
Behavioural: over training and under fuelling, training in secret, lying about amount of training or food eaten, reduced sleep or rate of recovery, inability to take rest days.
Performance: increased injury and illness, poor recovery between sessions, decrease in overall performance and results reduced energy, reduced fitness and muscle mass, digestive issues such as bloating affecting performance.
The Bottom Line
