The Female Athlete: Are There Risks?
Are you the parent of a female athlete? If so, this is an article you absolutely can’t skip over.
Engaging in athletics is a fantastic way for kids and young adults to build confidence, discipline, and healthy habits. As a certified sports nutritionist and coach, I’ve seen these benefits firsthand for over two decades.
But there’s a critical aspect that often gets overlooked in the drive to compete: nutrition.
When young athletes, particularly the dedicated female athlete, place high demands on their bodies without the right fuel, it can set off a chain reaction of serious health problems. This guide will break down the risks and give parents and coaches the knowledge to protect the young women in their care.

Key Takeaways for Protecting the Female Athlete
- The “Female Athlete Triad” refers to three interrelated conditions: low energy availability, menstrual dysfunction, and low bone density.
- The International Olympic Committee (IOC) has expanded this concept to Relative Energy Deficiency in Sport (RED-S) to include a wider range of health and performance consequences that affect both female and male athletes.
- Warning signs include fatigue, frequent injuries like stress fractures, loss of menstrual periods (amenorrhea), and changes in mood.
- A team approach involving parents, coaches, a physician, and a registered dietitian is crucial for prevention and treatment. Open communication is key to identifying issues early.

The Female Athlete Triad and RED-S Explained
Doctors are increasingly concerned about the health risks for girls in athletics who lack proper nutrition. A young female athlete burns a massive number of calories during training and competition. The problem arises when there isn’t enough focus on recovery and how to properly replenish the body’s energy stores.
When an athlete’s energy intake doesn’t match their energy output, it can lead to a condition doctors call the “Female Athlete Triad.”
This triad consists of three specific, interconnected issues:
- Low Energy Availability: This is the root cause. It happens when an athlete doesn’t consume enough calories to support their training demands and basic bodily functions. This can be intentional, through an eating disorder, or unintentional, simply from a lack of knowledge about their high energy needs.
- Menstrual Dysfunction: When the body is in a significant energy deficit, it shuts down non-essential processes, including the reproductive system. This can lead to irregular periods or the complete loss of a menstrual cycle, a condition known as amenorrhea.
- Low Bone Mineral Density: Estrogen, a key hormone in the menstrual cycle, is vital for bone health. When menstruation stops, estrogen levels drop, causing bones to weaken. This significantly increases the risk of stress fractures and can lead to osteoporosis later in life.
In 2014, the International Olympic Committee (IOC) introduced a broader term, Relative Energy Deficiency in Sport (RED-S), to better describe the issue. RED-S acknowledges that energy deficiency impacts much more than just the triad, affecting everything from metabolic rate and immunity to cardiovascular health and athletic performance in both female and male athletes. Parents who suspect an issue may need to consider specialized eating disorders in athletes treatment.
Warning Signs: What Parents and Coaches Must Look For
In my experience, many parents and coaches simply don’t know what to look for. It’s not about neglect, it’s about education. Recognizing the early warning signs is the most powerful step you can take to protect a young female athlete.
Doctors are now more proactive in screening young women about their activity levels, eating habits, and menstrual regularity. If they spot any red flags related to the triad, they work with parents and coaches to intervene before the problem escalates.
Here are the key signs that demand immediate attention:
- Performance and Physical Signs: Noticeable fatigue, decreased performance, or an inability to complete training sessions. Recurrent injuries, especially stress fractures, are a major red flag.
- Menstrual Irregularities: Any change from a regular cycle is a concern. Missing a period for three or more consecutive months is a critical warning sign that should be discussed with a doctor.
- Changes in Eating Habits: Restrictive dieting, avoiding certain food groups (like fats or carbs), or expressing anxiety about food and body weight.
- Mood and Behavioral Changes: Increased irritability, depression, anxiety, or social withdrawal can be linked to the physiological stress of under-fueling.
A Team Approach Is a Non-Negotiable
One researcher summed up the problem perfectly: “It has been my experience that coaches, parents, pediatricians and family practice physicians are not experienced in caring for athletes, and athletes themselves are not aware of the health risks unique to the triad for female athletes.”
This highlights the need for a collaborative, team-based approach to the athlete’s health. No single person can manage this alone. A strong support system should include the athlete, parents, coaches, a sports medicine physician, and a registered dietitian who specializes in sports nutrition.
The mental health aspect is also a crucial piece of the puzzle. The same researcher noted, “Parents, athletes, pediatricians, coaches and certified athletic trainers should be aware of signs and symptoms of eating disorders, including those athletes who display signs and symptoms of anxiety, depression, anger, isolation, and other behaviors that may indicate a mental health disorder.”
A 2022 study from the British Journal of Sports Medicine confirmed this, finding a high prevalence of anxiety and depression in athletes suffering from RED-S. This is not just about physical health, it’s about total well-being.
Athletics Can Open Doors for the Female Athlete
Learning to recognize these behaviors and risk factors is essential for keeping your child healthy. The benefits of sports for a young female athlete are immense, from building self-esteem and social skills to learning the value of hard work.
This article isn’t meant to deter you from encouraging participation in athletics. Instead, it’s a call to be proactive. By paying attention to the signs, you can ensure your child avoids the Female Athlete Triad and thrives.
Make sure she is eating enough to fuel her day, and just as importantly, make sure she is enjoying her life and her sport. At a young age, it’s about having fun and building a healthy foundation. Wins and losses are temporary, but a healthy relationship with food and exercise will last a lifetime.
FAQs About Risks with the Female Athlete
What is the difference between the Female Athlete Triad and RED-S?
The Female Athlete Triad focuses specifically on three components: low energy availability, menstrual dysfunction, and low bone density. Relative Energy Deficiency in Sport (RED-S) is a broader term that includes the Triad but also recognizes that low energy availability can impair many other body systems, including cardiovascular health, immunity, and psychological health, affecting both male and female athletes.
Can male athletes be affected by RED-S?
Yes. While they do not experience menstrual dysfunction, male athletes with low energy availability can suffer from reduced testosterone levels, poor bone health, and many other health and performance consequences outlined under the RED-S model.
How is the Female Athlete Triad diagnosed?
Diagnosis is typically made by a physician through a combination of a thorough medical history, physical exam, and sometimes blood tests to check hormone levels. A bone density scan (DEXA scan) may be ordered if a stress fracture has occurred or bone health is a significant concern.
What are the first steps to take if I suspect my daughter has this condition?
The first step is to schedule an appointment with her pediatrician or a sports medicine doctor to discuss your concerns. Be prepared to talk about her diet, training schedule, menstrual history, and any changes in mood or performance you have observed. From there, the doctor can recommend a plan, which will likely include a consultation with a registered dietitian or sports nutritionist.
