Background:
History
Athletic activity by women and girls has dramatically increased in the last 30 years. Much of this increase can be attributed to Title IX legislation, which mandated that equal monies and opportunities be made available to females at publicly funded institutions, particularly public schools, ranging from elementary schools to the universities. For the most part, this legislation has led to many health benefits, as generations of young women were given to chance to compete in a variety of sports. Women’s athletics has grown to the point that, today, women’s soccer and basketball have become professional sports in the United States. The number of girls participating in youth baseball or tee-ball has risen from almost a rarity 20 years ago to rates nearly matching those of their male counterparts.
With that increase in athleticism, the incidence of a triad of disorders particular to women has increased as well. This triad, the female athlete triad, almost exclusively occurs in the athletic subpopulation. It was first formally described at the 40th Annual American College of Sports Medicine Meeting in 1993, but observations about bone mineral densities, stress fractures, eating disorders, and female athletics were described for decades before the syndrome was named.
Often difficult to recognize, the female athlete triad can have a significant impact on morbidity and even mortality in a relatively young segment of the population. Indeed, the full impact of this syndrome may not be realized until these women reach menopause, when bone loss is accelerated.
Components of the triad
The components of the triad are amenorrhea, disordered eating, and osteoporosis. Not all patients have all 3 components of the triad.
Amenorrhea usually refers to secondary amenorrhea, although delayed menarche (primary amenorrhea) can occur in young athletes. By consensus, 3-6 consecutive missed menses is the requirement for diagnosis, although the continuum of normal menstruation may range from oligomenorrhea to amenorrhea.
Disordered eating includes anorexia nervosa and bulimia nervosa but is not limited to these diagnoses. The term disordered eating was coined to include pathologic eating behaviors that do not meet the strict requirements for anorexia or bulimia. These can include food restrictions; the use of diet pills, laxatives, and/or diuretics; a preoccupation with eating; and a fear of becoming fat.
In the young athletic population, osteoporosis refers to premature bone loss or inadequate bone formation leading to increased skeletal fragility, microarchitectural deterioration, and low bone mass. This can be manifested as multiple stress fractures or frank fractures. A high degree of suspicion is warranted in cases of unusual stress fractures (femoral neck or vertebral fractures) or in cases in which an athlete sustains stress fractures on a regular basis during her athletic career.
Frequency:
· In the US: Although all female athletes are at risk for the female athlete triad or any of its components, obtaining exact epidemiologic data is almost impossible because of the secretive nature of the disease. Similar to individuals with anorexia or bulimia, many athletes with the triad try to hide their symptoms or behavior from friends, family, trainers, or coaches. This is the primary reason why diagnosis is so difficult. In fact, the vast majority of cases are diagnosed only after advanced symptoms become apparent. Milder cases may be extremely difficult to diagnose if the physician does not already have a high degree of suspicion.
The prevalence of disordered eating in the female athletic population has been estimated to be as high as 62%, with the incidence of anorexia nervosa and bulimia (as defined in the Diagnostic and Statistical Manual of Mental Disorders 4th edition [DSM IV]) estimated as 4-39%. The use of questionnaires, surveys, or similar modalities may not be accurate in assessing conditions such as the female athlete triad, in which the very nature of the disease leads the patient to hide her symptoms or abnormal behavior.
In the near future, epidemiologic data regarding the female athlete triad may become available. Many preparticipation physical questionnaires now include questions about whether the athlete is satisfied with her current weight and about how much weight she would like to gain or lose. These simple inquiries may reveal the first warning signs of the triad.
Functional Anatomy: Stress fractures and lower-extremity, pelvic, and vertebral fractures are most typical in the osteoporotic bone observed in those with the female athlete triad. These fractures are most likely due the increased stress sustained by these bones in the course of physical activity. In this respect, athletes with the triad are not unlike their healthy counterparts. However, those who have the triad or portions of it are more susceptible to multiple fractures, and they are more likely to sustain fractures in larger, less commonly affected bones (eg, femoral neck, pelvis, vertebra).
Sport Specific Biomechanics: No particular sport is known for having a larger portion of its participants with the triad, but some generalizations can be made. Sports in which body type or weight seem important puts women at risk for the triad. Gymnastics, track and field, dance, and cheerleading have a higher percentage of women with the female athlete triad, as opposed to softball or weight lifting. Whether these sports cause the athletes to develop triad-related behavior or whether women with predispositions toward the female athlete triad are drawn to those sports as a way to hide their behavior is not known. Female swimmers with the female athlete triad may be at even greater risk for osteoporosis. These athletes lack the bone-preserving effect of weight-bearing exercise that may attenuate bone loss due to hormonal causes.


History: When an athlete is identified as being at risk for the female athlete triad, a detailed screening history should be obtained. The purpose of the screening process is to gather information about the patient's medical history and dietary and exercise behaviors and to evaluate the athlete for existing psychopathology and medical complications.
The team physician should not undertake every aspect of the evaluation and care of a woman with female athlete triad. A multidisciplinary approach should be used. If available and deemed necessary, consultation with a psychiatrist or clinical psychologist with experience in disordered eating, an orthopedic surgeon, a gynecologist, a cardiologist, a sports nutritionist, and the athlete’s athletic trainer should be added to the treatment team to augment the physicians personal knowledge of the athlete and team.
Past medical history
Particular attention should be given to any other endocrine disorders, such as thyroid abnormalities, panhypopituitarism, and diabetes. A careful and thorough history of past stress fractures and complete fractures should be elicited. The history should be verified with trainers, coaches, or parents if possible.
Menstrual history
This history should include the age of menarche, length of menses, and menstrual cycle, any missed menses, and menstrual pattern during the season or that period when the athlete is exercising the most. Athletes in some sports in which strength is important may be using anabolic steroids. This steroid use is a potential cause of secondary amenorrhea. Of course, the most common cause of secondary amenorrhea in young females is pregnancy, and this possibility should be discussed.
Psychosocial history
At the first visit, routine questions should be asked, such as those pertaining to tobacco or alcohol use. As trust is built up over the next few visits, further details about the patient's background should be elicited, such as illegal drug use, sexual or physical abuse, depression, previous eating disorders, suicidal behavior, recent trauma, or significant personal events.
The lack of family or social support system is a risk factor for the female athlete triad. Women just entering college are often a new environment physically distant from their friends and family. This move can be made more traumatic if the pressure to perform as a collegiate athlete is added to the athlete’s psyche. Sometimes, these women fall back on athletics—one of the few things that may have remained constant since high school—to gain acceptance from coaches and fellow athletes.
Exercise history
The number of hours per day that the athlete spends in practice and exercise should be determined. The examiner should make a point of asking not only how much time is spent in formal practice with the team or coach but also how much additional time is spent conditioning, running, lifting, etc, apart from scheduled workouts. The athlete should also be asked if this workout pattern changes during the off-season or if it continues year round.
Nutritional assessment
Just because the athlete is consuming what would otherwise be considered a normal number of calories per day does not mean that she is consuming enough calories for her lifestyle. Women who exercise for hours per day are likely to need more than the 1600-2000 kcal that their body weight would indicate.
The Eating Disorder Inventory (EDI), a questionnaire designed to help identify those with disordered eating may be used. Although it is not a precise instrument to aid in identifying eating disorders, it can be used to identify people at risk for anorexia or bulimia.
Some athletes with the triad adopt restrictive diets. These athletes sometimes use personal convictions or religious beliefs to justify their behavior. Many times, the athlete may develop a recognizable pattern of disordered eating in which they progressively establish and exceed dietary boundaries. For example, a diet of no red meat may progress to vegetarianism then to veganism over the course of months. The athlete's convictions may be subconscious excuses reflecting what is socially acceptable to her peers and authority figures. Of course, not every athlete with a diet that restricts certain foods has the female athlete triad. This is yet another reason why the diagnosis is difficult to establish.
Current medications
This part of the history should include the patient's over-the-counter (OTC) medications as well as herbal medicines and dietary supplementations. Many people do not consider OTC medicines “real” medicines. Athletes with the triad commonly use or abuse dietary supplements or ergogenic aids. Athletes may take the common stimulant ephedrine (ie, ma huang), to lose weight or to burn fat; however, this stimulant is known to cause mild tachycardia and has been at least temporally associated with several deaths in the athletic population. This tachycardia could potentially mask the bradycardia found in athletes with advanced eating disorders. Attention should also be directed toward any use of hormones, either now or in the past, because this can also cause menstrual irregularities.
Physical: In general, a complete screening physical examination should be preformed. As with history taking, postponing some parts of the physical examination until a relationship has developed between the athlete and physician may be appropriate. For example, a gynecological and breast examination may be better suited for a second or third visit. The exception to this rule is if the amenorrhea is primary, that is, if the athlete has never had normal menses. In this case, pelvic examination to verify the presence of a uterus should be performed at the first visit. Pelvic ultrasonography can aide in this determination. The diagnosis is largely clinical, and no test enables definitive diagnosis of the triad.
Many times, the physician diagnoses the stress fracture first; then the amenorrhea; and, lastly, the eating disorder. This sequence is almost the reverse of the order in which the female athlete triad develops.
Of note, female athletes come to a summertime preparticipation physical wearing many baggy clothes or sweatpants and sweatshirts are always suspect. Athletes with the triad may try to hide their body weight loss. In addition, some athletes may present for the examination and then refused the physician or any one else to examine them. This is often the case in 14- to 16-year-old athletes who participate in high-school sports.
· Anthropometric data and vital signs should be obtained without comment about weight or weight-to-height ratios.
o Body mass index (BMI) charts are calibrated for the general population and may not be suitable for the athletic subpopulation.
o If possible, the patient's percentage of body fat composition can be determined.
o Pediatric growth charts are often helpful in teenagers or college students.
· The remainder of the physical examination is directed toward other causes of amenorrhea or osteoporosis and secondary signs of the triad.
o The thyroid should be palpated for possible goiter.
o The parotid glands should be palpated for evidence of hypertrophy. This is sometimes found after chronic binging.
o Bulimia can cause bloodshot eyes and petechiae of the sclera or cheeks. Dental examination can show dental caries or pitting from the regurgitation of stomach acid through the oropharynx. If a finger is used to induce vomiting, the knuckles may be scarred from the patient biting down on them during regurgitation. The Russell sign is typical callous formation on the distal extensor surface of the long finger used to induce vomiting.
o Anorexia may cause cachexia, bradycardia, and hypotension later in the course of the disease. Although many well-conditioned athletes may have a resting heart rate below that of the general population, an ECG should be obtained if the athlete’s resting heart rate less than 50 beats per minute (bpm). Sinus bradycardia is a early cardiac sign in eating disorders, but conduction abnormalities (eg, atrioventricular conduction blocks, ventricular tachycardia) may become evident in more advanced cases. A baseline ECG might also be obtained for future comparison.
o Dermatologic examination sometimes reveals lanugo or the dry or yellow skin sometimes found in those with anorexia.
· Athletes with the female athlete triad usually report signs or symptoms related to osteoporosis (eg, fracture, stress fracture) before they report menstrual abnormalities.
Causes: The female athlete triad has no known causes. As discussed previously, athletes in some sports are more likely to have the triad, but whether these sports are somehow the cause of the triad or whether women with predisposition to the triad are attracted to these sports is unknown.
However, some factors do seem to predispose athletes to the female athlete triad. External life stressors, abrupt changes in body composition, a history of delayed menarche, menstrual irregularity, and/or nulliparity can predispose women to menstrual dysfunction and hypoestrogenic state leading to amenorrhea.
Emotional stressors can often be identified as inciting factors in athletes with the triad. For many, moving to a university setting initiates the pathology. Some young women may move long distances away from their family and friends, and they have the added increase in responsibility and academic workload that most freshmen experience. Collegiate athletes have the additional pressure of performing up to the more difficult standards of collegiate competition with a new coach and trainer and alongside athletes that may have had the benefit of 2-3 years of additional experience. Not surprisingly, the prevalence of the triad suddenly increases during the freshman year of college.


Other Problems to be Considered:
Hypothyroidism or hyperthyroidism
Pituitary disorders
Androgen excess (endogenous or exogenous)
Hypothalamic disorders
Drug interactions
Nutritional deficiencies
Hypogonadotropic hypoestrogenism
Luteal-phase inadequacy
Polycystic ovary disease
Ovarian defect (eg, Turner syndrome, gonadal dysgenesis)
Premature ovarian failure
Depression
Generalized anxiety disorder

Lab Studies:
· Urine or plasma pregnancy test to rule out pregnancy
· Complete blood count (CBC) determination to rule out anemia
· Erythrocyte sedimentation rate (ESR) to check for inflammation or infection: A C-reactive protein test may be ordered for verification, though it is not usually necessary because this problem is likely to have been present for months or years.
· Complete metabolic panel to evaluate liver function, electrolyte levels, and kidney function
· Thyroid panel to rule out hyperthyroidism and hypothyroidism: A thyroid-stimulating hormone (TSH) test is standard to rule out these diseases, and a free T4 test can be performed to confirm the results. The standard thyroid panel used in most laboratories is now outdated, and the TSH and T4 tests are the standard.
· Follicular-stimulating hormone (FSH) test to evaluate pituitary function
· Luteinizing hormone (LH) test to evaluate pituitary function
· Testosterone and dehydroepiandrosterone sulfate to evaluate androgen excess: Some forms may be nonvirilizing and therefore difficult to diagnose without a laboratory test.
· Direct estradiol measurements
Imaging Studies:
· If the athlete presents with bone pain, as with a stress fracture, appropriate plain radiographs should be obtained.
· Baseline dual-emission x-ray absorptiometric (DEXA) scans should be obtained in all athletes with the triad to identify undiagnosed osteoporosis or subclinical stress fractures, as well as to provide a reference for future monitoring.
· If the results of laboratory studies indicate abnormal pituitary function, thin-section MRI of the head should be performed through the sella turcica.
· In athletes with primary amenorrhea who lack a uterus (as determined at physical examination), pelvic ultrasonography can be used to verify the finding and to evaluate the presence and morphology of the ovaries. Hand images should also be obtained in these patients to establish their bone age.
· When a 3-phase bone scan depicts a stress fracture, further evaluation is usually not indicated. The presence of multiple stress fractures in an at-risk athlete is a warning sign for the female athlete triad.
Other Tests:
· The diagnosis is largely clinical, and no test enables definitive diagnosis of the triad.
· As mentioned previously, a resting ECG should be obtained in any athlete with a resting heart rate of less than 50 bpm. Many physicians believe that a baseline ECG should be performed in all athletes at risk for the triad. As with so many aspects of this disease, exact epidemiologic data are not yet available. Drawing on experience with anorexia and bulimia, for which a baseline ECG is usually recommended, proceeding with this noninvasive test may be a safe choice.
· A progesterone challenge test can be used to determine if the uterine endometrium has been primed with estrogen and thus be ready to be shed, as in normal menstruation. A course of 5 or 10 mg of oral progesterone (Provera) for 10 days can be used to induce menstrual bleeding. Lack of menses indicates that the uterine endometrium has not been adequately exposed to estrogen since the last menses. A positive test result is confirmed when menstrual flow occurs; this finding provides indirect confirmation of the presence of adequate amounts of estrogen to sustain endometrial growth.
Procedures:
· During the workup for amenorrhea, an evaluation of the endometrium may be necessary.
· The team physician can perform endometrial biopsy, or a consultation with the primary care physician or gynecologist should be requested.
o Endometrial sampling is performed by using a thin tube, usually a disposable pipette, inserted through the cervical os into the uterine cavity.
o Suction is then applied to the tube, and endometrial tissue is drawn into it.
o This sample can then be histologically examined to help determine the stage of growth of the endometrial tissue and thus the effects or presence of estrogen and progesterone.

Acute Phase:
· Rehabilitation Program:
o Physical Therapy: If a fracture or stress fracture is present, physical therapy may be appropriate, depending on the type of injury.
· Medical Issues/Complications: In the acute phase, treatment is aimed at addressing secondary complications of the female athlete triad. This treatment may involve immobilizing any stress fractures or prescribing a period of rest from athletic activities to allow the body to heal as much as possible.

Many initial laboratory and radiologic studies can be ordered at this time to aid in clinical decision making. For some tests, the patient may need to be referred to regional facilities or larger laboratories, and this time should be used to begin forming a relationship with the athlete. A restrained, understated manner often works to the advantage of the physician. For many people with disordered eating, their behavior represents a way of controlling at least one aspect of their lives. In the case of collegiate or professional athletes, many of their daily decisions are being made for them; they have control of only their eating habits and how they feel about their self-image.

The goal is to help the athlete to make the best decisions, especially in the initial visits. The athlete should not feel as though the medical staff is trying to take away her control. If a heavy-handed approach is used, many athletes may ignore or reject the advice given.
Although the physician may be able to restrict the patient's participation in organized practice and competition, most athletes also work out on their own, and they may continue to do so against medical advice. In early discussions with the athlete, the physician should persuade her to adhere to modest exercise reductions (eg, 10-20% reduction per week until acceptable goals are reached). More serious cases involving weight loss of more than 20% below the ideal body weight may require more aggressive activity cessation or even inpatient therapy, but fortunately, these cases are not as common as less severe cases.
The focus should be on lifestyle modifications. The athlete’s weight should not be used as the absolute indication of treatment success because body weight may been overemphasized already. Weight measurements should be taken as few times as possible, and once the patient has stopped losing weight, routine measurements should be stopped.
Dietary changes can also be made at this time, or a nutritionist may be consulted to address these issues. Again, modest changes should be attempted until a trusting relationship has been established.
Note: I agree with above but the approach must be individualized. Sometimes the coach/trainer/physician must agree that the athlete will not return to the team or to competition UNTIL the weight reaches a minimum value, i.e., the weight increases through lifestyle changes.
A team member or fellow athlete may also help with treatment. Most athletes with the female athlete triad either are loners or have only 1 friend on the team.
Hospitalization may be required at any time during the treatment process if it is determined that the athlete is continuing to harm herself or if she shows signs of multiorgan dysfunction due to extreme weight loss. The decision is highly individualized and should be made in consultation with a trained psychiatrist who is willing to treat such patients. Hospitalization for is often a long-term process, and months-long hospital stays are not uncommon. A good prognosis is far from ensured, even with optimal treatment.
· Surgical Intervention: Unless a fracture or stress fracture requires surgical intervention, surgery is usually not indicated.
· Consultations: A multidisciplinary approach should be used in the treatment of the female athlete triad. A team approach to care of the athlete with the team physician or primary care physician coordinating care is vital, not only to ensure that all details are covered but also to provide the athlete with an individual to whom she can always go to with questions.
A psychologist or psychiatrist familiar with eating disorders should be contacted for assistance with psychosocial issues. The consultant should be aware that most athletes do not meet the strict DSM IV criteria for bulimia or anorexia and that they are most likely to have disordered eating. Psychotherapy for behavior modification is often useful in adjusting habits that may be detrimental to the athlete’s health. Antidepressants or antipsychotic medications are rarely indicated for these patients.
Some physicians do recommend selective serotonin reuptake inhibitors (SSRIs) in individual cases. The advantage is treatment of the obsessive-compulsive disorder; however, a disadvantage is that some individuals lose weight. Therefore, the use of SSRIs is a judgment call.
A nutritionist is of great help, especially if he or she has experience in sports nutrition. Many larger universities and professional organizations employ a nutritionist to care for its athletes. Even if the athlete being treated is not a member of one of these organizations, the training or medical staff of these institutions may be able to provide the physician with a contact to provide assistance. The nutritionist should be able to help the medical staff in assessing the patient's caloric intake and output and to advise them about how to make modifications that will have maximal impact on the disease while causing the least amount of trepidation by the athlete.
A cardiologist may need to be consulted if cardiac arrhythmias are present. Cardiac arrhythmia is the leading cause of death in patients with anorexia and often starts as simple sinus bradycardia. Prompt referral should be made at the earliest sign of cardiac abnormality. Few patients with anorexia complain of classical chest pain or shortness of breath until late in the course of the disease.
If the athlete develops a fracture or stress fracture that requires surgical intervention, referral to an orthopedist is needed. Many such injuries can be managed conservatively; however, femoral neck stress fractures or compression vertebral fractures may require consultation with a specialist. If casts or braces are needed, they may need to be used for a longer period than usual because of the patient's altered nutritional status.
If the team physician is not comfortable with performing pelvic examinations, he or she should refer the athlete to her primary care provider or gynecologist. Endometrial biopsy is sometimes necessary as part of the workup for the triad, and this should be preformed by a physician experienced with these procedures.
Close contact with the coach and medical staff should be maintained to monitor the athlete's attitude, affect, practice regimen, eating patterns. Especially with athletes who travel for competition or who are part of an organized athletic squad, the athletic trainer may be able to report any unusual behavior. Skipped meals, meals taken by herself when the rest of the team is eating together, and exercising in addition to scheduled practices are all behaviors that should reported to the medical staff.
· Other Treatment (injection, manipulation, etc.): Other treatments can be directed at secondary musculoskeletal problems that may arise, but the focus should remain on the underlying problem of the triad.
Recovery phase:
· Rehabilitation Program:
o Physical Therapy: Physical therapy can be continued if needed.
· Medical Issues/Complications: Treatment should quickly move into the recovery phase to minimize further damage. This phase can involve the use of multiple medications and supplements directed at various systems in the athlete’s body.

Nutritional modifications can continue at this point, with the assistance of a sports nutritionist. Caloric intake should be increased slowly to avoiding compound the patient’s fear of becoming fat. A food diary and 24-hour recall can be used to monitor intake. If the athlete is part of a large college or university, its nutritional staff can prepare special diets and monitor the patient's intake. The athlete should be encouraged to eat with friends and during accepted eating times. Eating alone makes it easier for the patient to leave larger portions of the diet uneaten. A so-called food Buddy can make sure the athlete attends all meals and does not simply load her plate with lettuce and carrots and later define this as an adequate diet.
Activity modifications can help reduce the energy drain that may be contributing to the triad. Again, modest reductions in activity levels help prevent the athlete from ignoring the physician's recommendations. If the restrictions are too severe, the athlete may completely ignore them, with the justification that they are unreasonable. If necessary, a contract may be used to set guidelines for exercise. If the athlete ignores the recommendations of the physician or one of the consultants, their temporary removal from the team or sport may be imposed. This approach is obviously more difficult to enforce in athletes who have acquired the triad as part of an individual sport or outside organized sports. Moreover, this approach may change the athlete’s attitude toward the medical staff to a more adversarial tone. This change can lead to noncompliance or therapy failure.
Calcium and vitamin D dietary supplementation may help to minimize the osteoporosis that can occur with the female athlete triad, especially in athletes who have strict or unusual dietary restrictions. A dose of 1200-1500 mg of elemental calcium is suggested for young adults with premenopausal amenorrhea. Although only a few studies have been conducted to investigate the effects of calcium supplementation in women with the female athlete triad, its low cost and benign nature makes it a safe suggestion.
Hormone replacement therapy is commonly used in amenorrheic athletes despite the fact that only a few small studies have shown its benefit. Many formulations have been used. Conjugated unopposed estrogen (Premarin), combination estrogen with medroxyprogesterone acetate (Provera), or monophasic or polyphasic oral contraceptives pills can be used. The supplementation is designed to replace the lacking endogenous steroids with exogenous ones. Of course, the resumption of normal menses without benefit of hormone supplementation is a goal of therapy, but supplementation may offer a temporary solution. Hormone replacement regimens are thought to have an additive effect when used with supplemental calcium.
Again, a reduction and not cessation of activity should be emphasized early in the course of treatment. As previously suggested, a 10-20% reduction per week may be appropriate until acceptable goals are reached.
· Consultations: Continued close contact with consultants should be maintained.
· Other Treatment (injection, manipulation, etc.):


Medication:

Medical treatment is of secondary importance after changing the eating and exercise habits of the athletes affected with the female athlete triad. Some medicines can be used in conjunction with behavior modifications. The medications mainly consist of those used for hormone replacement and dietary supplementation.
Some physicians do recommend selective serotonin reuptake inhibitors (SSRIs) in individual cases. The advantage is treatment of the obsessive-compulsive disorder; however, a disadvantage is that some individuals lose weight. Therefore, the use of SSRIs is a judgment call.
Drug Category: Hormone Replacement -- Hormone replacements can be used in hypoestrogenic female patients who have been amenorrheic for 3-6 months despite changes in their diet and exercise pattern.

Return to Play: In mild-to-moderate cases of the female athlete triad, many athletes continue to participate in their activity even while in treatment. Activity modifications should be in place, however, and the time that the patient spends exercising should be closely monitored. When inquiring about exercise times, the physician should ask about formal practice sessions and exercise away from the structured environment. Often, this extra activity is burning much of the athlete’s caloric intake.

When the physician discusses exercise restrictions, the athlete often finds it easier to accept a restriction of her private workouts rather than her practice time with a team or coach. As with anorexia and bulimia, the triad is a secretive disorder. Just as the athlete may want to hide evidence of the disease, she may also try to hide evidence of the treatment. By allowing her to continue activity with her peers or coaches, she may not resist treatment.
Unless necessary, withdrawal from activity should not be used as a form of punishment for noncompliance or lack of objective improvement. This can often result of loss of the trust that has been built up and can lead to the athlete's resumption of self-directed exercise. Instead, the physician should work with the athlete to try to make her understand the necessity of the restrictions that are being set. This should minimize the likelihood of the athlete stopping therapy or being lost to follow-up.
If the athlete has been restricted from athletics because of poor compliance with the proscribed regimen or physical limitation (eg, stress fracture), a slow resumption of exercise should be attempted. In advanced or difficult cases, resumption of activity should not be allowed until the athlete is within 10-15% of the suggested body weight. Even in cases in which the athlete meets the weight goal, only slow resumption should be attempted. If a physical limitation is required (eg, to let a stress fracture heal), it may be needed for longer than usual to permit complete healing in the osteoporotic bone.
Complications: Continued bone loss leading to irreversible osteoporosis is the most worrisome complication of the triad. Some evidence suggests that bone mineral density can be regained to a small degree, but it is doubtful that significant loss can be completely corrected, even with years of therapy.
Multiple stress fractures or complete fractures can, of course, lead to increased incidence of osteoarthritis depending on the site of the fractures. Other fractures may heal without any long-term sequelae. Careful monitoring of these fractures should be provided, as they may take longer to heal than one would expect. The negative nutritional balance often leads to slowed or delayed healing of fractures.
End-stage eating disorders can result in more serious complications, such as prolonged hospitalization, cardiac arrhythmias or even death. Anorexia nervosa has an estimated mortality rate of 15% once the diagnosis is made. Compared with others, athletes are less likely to meet the criteria for anorexia or bulimia, but significant morbidity and mortality can occur.
Prevention: Because of the difficulty in diagnosing the female athlete triad and in treating patients with the condition, prevention is fundamental in reducing morbidity and mortality rates. Early detection reduces symptoms and decreases the likelihood of serious long-term consequences.
Currently, there is substantial debate between physicians and the coaching community regarding the role of weigh-ins for sports. Some coaches or instructors have strict guidelines based on height or body type, and they set maximal weights for eligibility for competition. This regimented approach often places increased stress on the athlete and sends the wrong message about the importance of weight. It also does not account for how well the athlete has been performing in their sport. (For example, how would the coach handle a situation in which the best athlete on the team is also 5 lbs. over the weight limit?)
The situation can made worse when overweight athletes are "punished" with running or performing push-ups or when they are forced to weigh-in in front of the team. As a beginning step, the team physician should discourage such public weigh-ins and punishment and emphasize specific athletic achievement instead of weight.
The preparticipation physical examination presents an ideal opportunity to screen all female athletes for signs or symptoms of the triad. A high index of suspicion should be maintained for all female athletes because of the difficulty in diagnosing this disease. Many preparticipation questionnaires now include questions concerning the athlete's menstrual history and contentment with her current body weight. These questions often bring otherwise asymptomatic individuals to the attention of the medical and training staff. If these questions are not a part of the questionnaire, the physician should consider making them part of his or her routine examination. Most women will not volunteer this information unless asked; therefore, a proactive approach should be used in routine history taking.
Better education of team physicians, other health care providers, trainers, coaches, parents, and the athletes themselves should reduce the yearly incidence of the triad. Many young women consider oligomenorrhea or amenorrhea during the season or at times of peak activity a sign of hard work and dedication. Not long ago, the medical community considered athletic amenorrhea a benign condition and treated it as such. If both the athlete and physician are aware of the potential damage that can occur, they may be able to prevent this insidious disease.
Prognosis: For many athletes, the long-term prognosis is good. Few athletes with the female athlete triad are admitted to the hospital for inpatient treatment, and few die from their disease. However, significant long-term morbidity may affect these women later in life.
The diagnosis of the female athlete triad was established in the early 1990s, and this constellation of symptoms had been noted for years before a name was given to it. However, no long-term data about future problems are available. The first generation of athletes in whom this condition was diagnosed is still years away from menopause. Therefore, whether osteoporosis occurring at a younger age affects mortality or leads to more advanced osteoporosis later in life or an increased risk of significant fractures (eg, hip fractures) is unknown.
For mild-to-moderate cases, some resolution of the osteoporosis is thought to occur. The lost bone mineral density is unlikely to be replaced in its entirety, and the bone mass that should have been accumulated during this important time in bone development may or may not be regained. However, many case reports show that bone density does not increase, and the losses may be permanents. Unfortunately, no long-term, double-blinded, controlled studies are available (and cannot be performed). As more information about the female athlete triad and its complications is gathered, everyone involved may better understand the significant morbidity that can occur years or decades after the disease is diagnosed and treated.
Education: Educating athletes may lead to earlier detection of the female athlete triad. If women know that amenorrhea is not a positive sign of hard work but a harbinger of disease, they may seek treatment sooner. Of course, the triad has a secretive nature, and once an athlete is showing signs of disordered eating, education may not be enough to help these women seek help. If the general athletic population is aware of the signs and symptoms of this disease, the disease might be caught in its early stages.
Physicians need to do better in educating trainers, coaches, and parents. These are the people who will have daily contact with the athlete, and they may be the persons who first raise concerns about a particular athlete. Taking the time to talk to the athletic staff about the warning signs may help in preventing the disease or catching it in its early stages.


Medical/Legal Pitfalls:
· The main medicolegal complication is most likely the failure to diagnose the female athlete triad in a timely manner.
· Because the diagnosis was formalized less than a decade ago, the direction the legal community has decided to take regarding the triad is still being established.
· Medical malpractice suits are likely to follow patterns established in the diagnosis of anorexia and bulimia.
· Although the diagnosis is relatively new, legal-civil penalties could be harsh because of the severity of the disease and the population it affects.
· As with most diseases, timely diagnosis and initiation of treatment is paramount in avoiding lawsuits. Diagnosis of the female athlete triad can be delayed because the stress fracture is diagnosed first, followed by the amenorrhea and, lastly, the eating disorder.
· What may make civil litigation difficult are the secretive nature of the disease and the significant rate of patient noncompliance with treatment.
· Even with rapid diagnosis and treatment, bad outcomes are possible.
Special Concerns:
· The female athlete triad affects a specific subpopulation, and as such, it poses a few special concerns to consider.
· Pregnancy is usually not an issue because of the amenorrhea involved with the triad. If the athlete is lacking this portion of the triad, pregnancy is still unlikely because of the physical and nutritional stresses she is experiencing. If the athlete does become pregnant while exhibiting other signs of the triad, a more aggressive approach must be pursued in decreasing her activity levels and in addressing her nutritional changes.
· The female athlete triad rarely affects women older than 40-50 years. By far, most women affected are in their early teens to late 20s. This disease is simply not one that affects the geriatric population. It can, however, affect girls who have not yet experienced menarche. In these patients, differentiating primary amenorrhea from congenital abnormalities or hormonal imbalances during the initial workup becomes significantly more important.
