Female Athlete Triad

---

Overview

The Female Athlete Triad is a clinical condition seen in physically active females, especially in sports that emphasize:

• Low body weight
• Aesthetic appearance
• Endurance performance

---

Commonly Affected Athletes

• Gymnastics
• Ballet and dance
• Endurance runners
• Weight-category sports (e.g., bodybuilding, wrestling)

---

Definition

The triad consists of three interrelated components:

• Low energy availability (± disordered eating)
• Menstrual dysfunction (amenorrhea)
• Low bone mineral density (osteopenia/osteoporosis)

---

Key Concepts

• Each component exists on a spectrum (mild — severe)
• All three components need not be present
• Presence of one component should prompt evaluation for others

---

Clinical Insight

• A stress fracture in a young female athlete should always trigger:
  • Nutritional assessment
  • Menstrual history evaluation

---

Components of the Female Athlete Triad

---

1. Low Energy Availability / Disordered Eating

---

Definition

• Energy intake insufficient to meet:
  • Exercise demands
  • Normal physiological functions

---

Causes

• Intentional calorie restriction
• Desire to maintain low body weight or body fat
• May occur with or without a formal eating disorder

---

Consequences

• Negative energy balance
• Hormonal disruption
• Impaired metabolic function

---

2. Menstrual Dysfunction (Amenorrhea)

---

Cause

• Energy deficit— hypothalamic suppression

---

Mechanism

• Reduced GnRH— decreased estrogen production
• Leads to functional hypothalamic amenorrhea

---

Clinical Features

• Common in:
  • Runners
  • Ballet dancers
  • Lean athletes

---

Types of Amenorrhea

---

Primary Amenorrhea

• No menstruation by age 15–16 years

---

Secondary Amenorrhea

• Absence of menstruation for:
  • >/=3 consecutive cycles
  • OR ?6 months

---

3. Low Bone Mineral Density

---

Cause

• Reduced estrogen levels

---

Results

• Osteopenia
• Osteoporosis

---

Clinical Consequences

• Bone fragility
• Increased risk of:
  • Stress fractures

---

Important Fact

• 90% of peak bone mass achieved by:
  • End of adolescence

 Critical period for bone health

---

Management and Treatment

---

Treatment Goals

---

• Early recognition
• Correction of energy imbalance
• Restoration of normal menstruation
• Preservation/improvement of bone density

---

Management Strategies

---

Nutritional Management

• Increase caloric intake
• Optimize overall nutrition
• Adequate:
  • Calcium
  • Vitamin D

---

Activity Modification

• Reduce training intensity or volume if required

---

Education

• Counseling regarding:
  • Nutrition
  • Long-term health risks

---

Multidisciplinary Approach

---

Management should involve:

• Physician
• Athletic trainer
• Sports nutritionist / dietitian
• Psychologist or mental health professional

---

Clinical Evaluation

---

When to Suspect

• Female athlete with:
  • Stress fractures
  • Menstrual irregularities
  • Low body weight

---

Assessment Should Include

---

History

• Menstrual history
• Dietary habits

---

Investigations

• Bone mineral density (DXA scan)

---

Screening

• Eating disorders
• Psychological factors

---

Key Takeaways

---

• Female Athlete Triad is a spectrum disorder, not always a complete triad
• Early identification prevents:
  • Osteoporosis
  • Recurrent stress fractures
• Energy deficiency is the root cause
• Requires multidisciplinary management
