Female Athlete Triad
(Exercise-Related Menstrual Dysfunction: Athletic Amenorrhea)
Female athlete triad is a mix of:
- Decreased energy—with or without an eating disorder
- Changes in menstruation (periods)—may be irregular or fully stopped
- Loss of bone and body mass—with or without osteoporosis

The triad happens when the amount of calories eaten is much lower than amount used by the body. This decreases a hormone called estrogen. This causes periods to change. It also makes it hard for the bones to absorb calcium. This causes them to weaken.
- Decreasing the amount of food eaten while raising activity level
- Not eating enough of the right foods to support high levels of activity
This problem is more common in competitive athletes. Other things that may raise the risk of this problem are:
- Exercising beyond the level needed for a sport
- Being in sports that focus on being thin or low body weight, such as gymnastics, ballet, figure skating, and distance running
- Being an athlete in sports that have weight classes
- Pressure to lose weight from parents or coaches who think weight loss will help performance
- Restrictive dieting
- Binge eating
- Forced vomiting
- Excess worry about weight and eating
- Low self-esteem or poor family dynamics
Problems may be:
- Weight loss
- Missing or irregular periods
- A decline in sports performance
- Focus and mood problems
- Feeling very cold
- Muscle cramps or weakness
- Poor self image
The doctor will ask about your symptoms and health history. A physical exam will be done. You will also be asked about your medicines, diet, periods, and exercise routine. This is often enough to make the diagnosis.
The goals of treatment are to gain weight and resume normal periods. Treatment will be based on specific needs. More than one of the following may be needed:
- Nutrition counseling to balance calories with activity level
- Cognitive behavioral or group therapy to change unhealthy thought processes
- Medicines, such as:
- Hormones found in birth control pills
- Supplements like calcium and vitamin D to strengthen bones
The risk of this problem may be lowered by:
- Maintaining a healthy weight
- Eating enough calories to fuel activities
