Eating disorders can have devastating effects on athlete health and performance. Although females represent approximately 90% of those who seek medical care for an eating disorder, males can be affected as well.1–3 Understanding the epidemiology and pathophysiology of eating disorders allows the sports medicine clinician to optimise his or her role in screening at-risk athletes and providing treatment. By intervening early and comprehensively, clinicians can decrease serious health and performance consequences.
In the USA, it is estimated that 10 million women, and 1 million men will suffer from a clinically significant eating disorder in their lifetime.4 ,5 Given the secretive nature and denial surrounding eating disorders, these numbers likely grossly under-represent the total disease burden in the US population. In a Finnish community study, approximately half of all individuals with anorexia nervosa had not yet been identified by the healthcare system.2 Worldwide, rates of eating disorders in Western societies parallel those in the USA, whereas in developing countries, the likelihood of disease is considerably less.1 ,6–11 Among athletes, estimating the prevalence of eating disorders remains somewhat elusive.
Disordered eating is more prevalent among athletes than non-athletes,12 illustrating the relative importance of this problem in the athletic community. The majority of studies investigate the prevalence of eating disorders in female athletes. In a study of 522 elite female athletes and 448 non-athlete controls completing a disordered eating questionnaire, clinical examination and interview,13 18% of athletes were diagnosed with an eating disorder compared to only 5% of non-athlete controls. In addition, athletes tended to under-report disordered eating symptoms on questionnaires compared to the control group. A similar but larger study including 1620 athletes and 1696 controls found similar results—20% of female athletes met criteria for an eating disorder, compared to 9% of female controls.12
Even among female athletes the rates of eating disorder vary by sport and have generally been higher in sports with weight classes (such as rowing), aesthetic sports (such as gymnastics or figure skating) and sports where having a low body mass is seen as advantageous (such as cross-country or cycling). These conclusions were supported by Sundgot-Borgen's13 study that found rates of eating disorders in aesthetic sports and weight-dependent sports were 25%, compared to 12% in other sports. In the 2004 study the prevalence of eating disorders in aesthetic sports was 42%, in endurance sports it was 24%, in technical sports it was 17% and in ballgame sports it was 16%.12 Similarly, in a 2015 study of 108 elite German athletes who were age-matched with 108 non-athlete controls, rates of eating disorders were 17% in aesthetic sports, 2% in ball sports and 2% in non-athletes.14
Additional studies suggest that the prevalence of disordered eating behaviours (such as binging, using saunas, taking laxatives or diuretics, self-inducing vomiting, etc) is higher in the college-aged population, even in the absence of a formal eating disorder diagnosis.15 Similar to the trend in eating disorder prevalence, athletes in lean sports exhibited more disordered eating behaviours than non-lean sport athletes.13 ,16 Glazer17 found that disordered eating scores on standardised questionnaires were higher in athletes than non-athletes, and highest in athletes within physique salient sports. An Australian study also found that disordered eating behaviours and body dissatisfaction were higher in lean sports, regardless of level of competition.18 In some studies as much as 70% of athletes in weight class sports were dieting or exhibiting abnormal eating behaviours to reduce their weight before competition.8
Eating disorders in male athletes
An increasingly large body of research also indicates that eating disorders and disordered eating are significant problems among male athletes.7 ,9 ,12 ,17 ,19–23 In general, male athletes have a lower prevalence of eating disorders than female athletes, but a higher prevalence than male non-athletes. In one study, 20% of female athletes and 8% of male athletes met criteria for an eating disorder, compared to 9% of female controls and 0.5% of male controls.12 Another study of male and female rowers supported this trend by showing that male athletes had higher rates of pathological eating behaviours than the general male population–12% of men had reported at least two binge eating episodes per week, 3% of men had self-induced vomiting and rates of rapid weight fluctuation and fasting were even higher in male athletes than female athletes (57% vs 25%).23 Similar to the trend seen in elite female athletes, male athletes in lean sports are more likely to suffer from an eating disorder than those in other sports. In a 2004 study rates of eating disorders in male athletes in antigravitation sports were 22%, as compared to 9% in endurance sports and 5% in ball game sports.12 In a study by Rosendahl, et al,24 the prevalence of eating disorders among male athletes was 10% in endurance sports, 17% in weight class sports and 42% in antigravitation sports. As was observed in the female athlete population, numerous studies focusing specifically on male athletes in lean sports have found similarly high rates of disordered eating in this population, even in the absence of a formal eating disorder diagnosis.9 ,17 ,22 ,25 ,26 In a survey of 732 male collegiate athletes in the USA, Chatterton and Petrie22 found that male athletes who participated in weight class sports were more likely to engage in pathological eating and weight control behaviours and be symptomatic compared to male athletes in endurance sports or ball game athletes.
The importance of eating disorders in athletes is further emphasised by concerns that rates of eating disorders are increasing in the general population among individuals age 15–19 years old.1 While this may be partially explained by changes to DSM-V criteria and greater awareness surrounding the Female Athlete Triad, it may also reflect broader cultural changes including public health efforts to reduce the burden of obesity.
The majority of the studies mentioned above were conducted using definitions of eating disorders from the Diagnostic and Statistical Manual of Mental Disorders (DSM). The release of the DSM V has provided several important updates to the diagnostic criteria (tables 1⇓–3). One study found that according to DSM IV criteria, 81% of adolescents and 75% of adults who presented for treatment of eating disorders were classified as ‘eating disorder not otherwise specified’ (EDNOS) because they did not meet all of the criteria for one type of eating disorder.27 The changes in the DSM V are intended to reduce the number of diagnoses which fall into the EDNOS category (or its renamed counterpart), which should facilitate more accurate descriptions of patient symptoms and also further research on eating disorders. Several studies have shown reductions in EDNOS diagnosis rates using the DSM V criteria.28 ,29
The criteria for anorexia nervosa have undergone the greatest number of revisions. Previously, individuals were required to have a weight less than 85% of normal. This has been updated to state that significantly low weight is ‘less than minimally normal weight in adults or less than expected weight in children and adolescents.’ Additionally patients no longer need to explicitly endorse a fear of weight gain; this can now be inferred from patient behaviours. This change is likely to be particularly beneficial in the athlete population, because athletes may deny symptoms in an effort to continue competing. Lastly, amenorrhoea has been discarded as a diagnostic criterion for anorexia. Studies found that women who otherwise met criteria for anorexia but still had regular (or irregular) menses did not differ clinically from women with similar symptoms plus amenorrhoea.6 Removing amenorrhoea as a diagnostic requirement also facilitates the diagnosis of anorexia in men, postmenopausal women and adolescents with delayed menarche.
The new definition for bulimia nervosa in the DSM V reduced the required frequency of binge episodes and compensatory behaviours from twice per week to an average of once per week over a period of 3 months. This change was made because the frequency of binge episodes did not significantly impact prognosis or treatment, and it caused more EDNOS diagnoses.30 The DSM V also created a new diagnosis that had previously fallen under EDNOS—binge eating disorder. Lastly, the miscellaneous category previously called EDNOS has been changed to two categories—‘other specified feeding or eating disorder,’ and ‘unspecified feeding or eating disorder.’ The first of these categories is used for individuals who have a specific reason why they do not meet criteria for one of the types of eating disorder. For example, it would include a patient who had lost significant weight but was still within the normal weight range despite meeting all other criteria for anorexia. The second category is used in situations where the clinician cannot or does not clarify the reasons why the patient fails to meet full criteria for an eating disorder.
Individuals affected by eating disorders commonly suffer from other mental health conditions, including depression, anxiety, obsessive-compulsive disorder and substance use disorder. In a Canadian study almost half of all patients with eating problems were also found to have mood or anxiety disorders.31 Similarly, in a Swedish study half of patients with eating disorders had depression and one-quarter endorsed substance abuse.32 Lifetime prevalence of substance abuse in patients with bulimia nervosa is at least 30%.10 Furthermore, among patients with bulimia nervosa, those with comorbid psychiatric conditions were more likely to report suicidal ideation and history of suicide attempts.33 Binge eating disorder has been found to significantly co-occur with depression, bipolar disorder, anxiety, bulimia nervosa, kleptomania and body dysmorphic disorder.34 Limited data exists regarding the relationship between eating disorders and comorbid mental health conditions in female and male athletes. A study in British athletes found a positive and significant relationship between eating psychopathology and risk of subsequent depressive symptoms 6 months later.35 Importantly, clinicians caring for an athlete with an eating disorder should consider and evaluate for other mental health conditions.
In addition to the aforementioned mental health conditions, premorbid medical conditions can increase the likelihood of subsequent eating disorders and contribute significantly to the morbidity of eating disorders. For example, individuals with type 1 diabetes mellitus are at higher risk for eating disorders later in life—in a German study, one in three females with type 1 diabetes and one in six males with type 1 diabetes had disordered eating and insulin restriction.36 Data on athletes with type 1 diabetes and eating disorders is unknown. Gastrointestinal conditions such as chronic constipation, gastroesophageal reflux disease (GERD), coeliac disease, lactose intolerance, delayed gastric emptying, gastroparesis and superior mesenteric artery syndrome may all occur as a result of eating disordered behaviour,37–39 and in some cases may predate the eating disorder, thereby contributing to its onset.39
Consequences of eating disorders
There are both health and performance consequences of eating disorders.
Eating disorders have wide-ranging health consequences, including one of the highest mortality rates of any mental health condition.10 ,37 ,40 Risk of premature death is 6–12 times higher in women with anorexia nervosa.41 Crude mortality rate is approximately 5% per decade.10 In 1994 the death of US gymnast Christy Henrich from anorexia nervosa was a devastating example of the extent to which athletes will manipulate their dietary intake and exercise to achieve what is perceived as an ideal body image. Death is most often caused by suicide or cardiac arrhythmia—suicide accounts for 20% of deaths among patients with anorexia nervosa, and 23% of deaths among patients with bulimia nervosa.42 ,43 Particularly worrisome is the finding that among individuals with an eating disorder, over-exercise (common among competitive athletes) is the disordered eating behaviour which is most strongly associated with suicidal behaviour.44 Death from cardiac arrhythmia may result from electrolyte disturbances associated with self-induced vomiting, laxative abuse and diuretic use, especially among those with extremely low body weight. While cardiac consequences of eating disorders—especially anorexia nervosa—are considered a significant contributor to morbidity and mortality,45 a recent meta-analysis of mortality rates in anorexia nervosa was unable to elucidate exact cause of death, aside from medical causes versus suicide.46
Disordered eating behaviours such as restricted dietary intake, excessive exercise, binge eating, self-induced vomiting, laxative abuse, diuretic use, regurgitation and eat and spit, can affect nearly every system of the human body. While some individuals practice a single behaviour such as restriction, studies suggest that up to a third of individuals engage in two or more pathogenic behaviours.47 ,48 Furthermore, individuals who report using multiple compensatory behaviours have more severe presentations of eating disorders, lower levels of functioning and increased rates of general psychopathology.48 As athletes may approach the medical care team for evaluation of an ‘eating disorder consequence’ rather than seeking care directly for an eating disorder, sports medicine clinicians should be aware of the signs and symptoms of restricting and purging behaviours49 (table 1).
Among female athletes with eating disorders, especially those with restricted dietary intake, a commonly recognised consequence is the Female Athlete Triad. The Triad describes three distinct but inter-related conditions including low energy availability, menstrual dysfunction and low bone mineral density.49 ,51 ,52 Low energy availability (whether inadvertent, intentional or psychopathological), can result from low energy intake relative to high energy expenditure during training and is the underlying factor contributing to negative effects on reproductive and skeletal health.51 ,52
While not as extensively studied, there is increasing research on the health consequences of disordered eating in the male athlete. In a subset of male athletes, especially those participating in sports emphasising leanness, parallels to the Triad have been described53 that include low energy availability (with or without disordered eating)7 ,9 ,12 ,16 ,19–23 (hypogonadotropic hypogonadism or other gonadal steroid effects54–58) and low bone mineral density.59–66 Similar to the female athlete, male athletes with low energy availability (with or without disordered eating) may be predisposed to stress fractures and bone stress injuries.61 ,66 However, our current understanding of the mechanisms of nutrition and low energy availability on neuroendocrine function and bone health in males is limited compared to that for female athletes and further research is needed.
Athletic performance suffers as a result of eating disorders.67 Female athletes with anorexia nervosa and a body mass index (BMI) <16.5, and those with bulimia nervosa purging four or more times per day should be categorically restricted from participation in sport.51 Additionally, low energy availability leading to the loss of fat and lean body mass, electrolyte abnormalities and dehydration all contribute to poor sport performance.67 A study of junior elite female swimmers, found that those with energy restriction and ovarian suppression had poor sport performance compared to cyclic swimmers.68 Even among high school athletes, those with disordered eating behaviours were more than twice as likely to sustain a musculoskeletal injury during their competitive season.69
Screening for eating disorders in athletes
Several US sports medicine professional organisations (including the American Medical Society for Sports Medicine (AMSSM) and the American College of Sports Medicine (ACSM) have collaborated to develop the Preparticipation Physical Examination (PPE) monograph.70 Now in its fourth edition, the PPE includes several questions aimed at identification of disordered eating behaviours:
Do you worry about your weight?
Are you trying to, or has anyone recommended that you gain or lose weight?
Are you on a special diet or do you avoid certain types of food?
Have you ever had an eating disorder?
Have you ever taken any supplements to help you gain or lose weight or improve your performance?
Additional questions on the PPE questionnaire screen for downstream consequences of eating disorders including menstrual dysfunction (in female athletes), and stress fractures, mood disturbance and substance use (in female and male athletes).70 Clinicians should maintain a high index of suspicion for disordered eating since some studies show that athletes tend to under-report disordered eating behaviours on questionnaires.13
The Female Athlete Triad Coalition has published an 11-question screening tool (box 1) that aims to identify disordered eating, menstrual dysfunction and low bone mineral density.51 It is recommended that these questions be administered to athletes during the preparticipation examination.
Recommended screening questions for the female athlete triad51
Have you ever had a menstrual period?
How old were you when you had your first menstrual period?
When was your most recent menstrual period?
How many periods have you had in the past 12 months?
Are you presently taking any female hormones (oestrogen, progesterone, birth control pills)?
Do you worry about your weight?
Are you trying to or has anyone recommended that you gain or lose weight?
Are you on a special diet or do you avoid certain types of foods or food groups?
Have you ever had an eating disorder?
Have you ever had a stress fracture?
Have you ever been told you have low bone density (osteopenia or osteoporosis)?
These questions should be included as a part of the preparticipation physical examination (PPE).

Diagnosis and evaluation of athletes with eating disorders
Sports medicine providers serve an important role in evaluating disordered eating and diagnosing eating disorders. Physicians, athletic trainers, sport psychologists, sport dietitians and physical therapists interact with athletes and active persons, and may have an opportunity to identify eating disordered behaviours. Early identification and early intervention are associated with better outcomes.3 ,39 Referral of an athlete suspected of engaging in unhealthy eating behaviours to a physician with expertise in the evaluation and management of eating disorders, and especially with additional knowledge regarding the interaction with competitive sport, is a key first step. As is often the case in medicine, ‘the mystery is in the history,’ and given the secretive nature of eating disorders, this adage is particularly applicable when caring for athletes with eating disorders. Questions such as, ‘what percentage of your waking hours do you spend thinking about food, weight and body image?’ and ‘in what ways does your weight affect the way you think about yourself?’ are but a few questions that often open up a dialogue about feelings, eating behaviours and health consequences. A more complete list of questions to consider integrating into the medical history when evaluating an athlete suspected of having disordered eating or an eating disorder can be found in table 2.
A review of systems and a comprehensive physical examination (table 1) can further aid in the identification of disordered eating behaviours and health consequences, leading to diagnosis as well as subsequent treatment. Laboratory evaluation and additional diagnostic testing are often required to better assess health consequences. Both historical and physical examination findings should guide the laboratory and additional diagnostic evaluation3 ,52 (table 3). Female athletes who develop menstrual dysfunction and/or evidence of low bone mineral density—the Female Athlete Triad—should undergo testing of their reproductive hormones and evaluation of their bone mineral density as defined in the 2014 Female Athlete Triad Coalition Consensus Statement on Treatment and Return to Play of the Female Athlete Triad.51
Treatment of disordered eating and eating disorders in athletes
Once a diagnosis of disordered eating or an eating disorder has been made, a knowledgeable and experienced multidisciplinary team of healthcare professionals should care for the athlete, with a goal of personalised patient-centered care (figure 1). The first step in treatment is determining the level of care. Can the athlete be treated in an outpatient setting, or does he or she require a higher level of care in the hospital or in a residential treatment setting? Deteriorating physical and/or mental health are the primary reasons prompting a higher level of care—examples include rapid uncontrolled weight loss, severe electrolyte abnormalities, syncope, suicidal intent and inability to function in one's environment. The majority of individuals can be treated in an outpatient setting using the multidisciplinary team care model. In the athletic setting the team often consists of a physician, a sports dietitian, a mental health professional and the athletic trainer. Communication among team members is critically important. The individual affected by the eating disorder must feel like he or she is receiving a cohesive and consistent message from the treatment team. While each member of the team plays a unique role in supporting the athlete's recovery from the eating disorder, there is considerable crossover in the care that team members provide—with the physician talking about nutrition, or the dietitian discussing feelings and function alongside calories and carbohydrates. Setting aside time for the team to ‘round’ and share important information about the athlete can help to facilitate care. Additional health professionals may have a consulting role in the care of the athlete affected by an eating disorder (such as psychiatry, or gastroenterology).
For younger athletes still living at home, engagement and alignment with parents or guardians is critically important. Knowing that chaotic or disruptive family situations (such as divorcing parents) can contribute to the development of an eating disorder, it is imperative that the multidisciplinary treatment team understands the environment in which the athlete lives, and takes that into account when developing and implementing treatment plans.39
The primary role of the physician is to address the eating disordered behaviours and their health consequences, and to support and reinforce the treatment plans of the dietitian, mental health professional and others involved in the athlete's care. Healthcare visits are typically monthly, although may be more or less frequent depending on the athlete's stage of recovery. Medical care should focus on the following areas:
Function—Assessing day-to-day functioning
How have you been doing since your last visit?
Is there a time of day that your behaviours are better or worse?
What helps you succeed (with changing behaviours, with treatment, etc)?
Are you taking your medications as prescribed?
Additional questions to develop rapport and further assess patient functioning (eg, ‘How is school? Practice? Work? Family/Friends?’).
Physical health discussion—Discussing health-related topics, such as:
A targeted symptom review: sleep, bowel habits, energy, urination, palpitations, syncope/near-syncope, menstruation, other issues or concerns
Eating behaviours—restriction, binging, purging, etc
Exercise and training behaviours—healthy and unhealthy; issues related to clearance and return to play
Mental status—Assessing the patient's mental health with a standard mental status examination (MSE) and discussion of various topics, such as body image, stressors, and mental health issues.
Physical health examination—Checking and recording the following:
Vital signs—blinded weight, height, BMI, blood pressure, heart rate, temperature
Change in weight since last visit
Physical examination if necessary—throat, heart, lungs, extremities, etc
Repeated tests/examination items from diagnosis as necessary
Medications—Prescribing and managing medications as needed.
Other health needs as necessary—Reviewing menstrual function, digestive issues, bone health, endocrinology manifestations, etc.
Medications are often prescribed to patients with eating disorders to treat comorbid conditions such as depression and anxiety, or to manage physical complications. Target symptoms should be established with the patient and regularly monitored. Only two psychotropic medications have US Food and Drug Administration approval for the direct treatment of eating disorders—fluoxetine for use in patients with bulimia nervosa39 ,71 and lisdexamfetamine for use in patients with binge eating disorder.72 ,73 However, there is considerable off-label use of psychotropic medications ranging from antidepressants,39 ,71 ,74 anxiolytics,74 antipsychotics75 and antiepileptics74 in an effort to curb eating disorder behaviours and treat comorbid symptoms of depression and anxiety, obsessive compulsive behaviours, thought disorder and sleep disturbance. Despite the use of these medications, there is limited evidence that use of psychotropic medications in the treatment of eating disorders is associated with improved clinical outcomes.76 It is also worth noting that the majority of the studies looking at treatment protocols for eating disorders do not distinguish between male and female patients, so it is unclear whether optimal treatment strategies differ by sex.17 Physicians should carefully consider the potential risks and benefits in prescribing psychotropic medications.
Patients may also benefit from additional medications, vitamins and supplements to treat health consequences of eating disordered behaviours.51 ,77 This includes the use of potassium replacement for hypokalaemia resulting from self-induced vomiting; hormone therapy for female patients with clinical indications for replacement,51 and medications aimed at addressing impaired gastrointestinal motility.77
Sports medicine physicians should be aware of the unique interaction between medications and sport participation. For example, medications that induce orthostatic hypotension should not be prescribed to a gymnast who experiences many changes in posture and position. Likewise, sedating medications may not be tolerated by student athletes attending school, practice or trying to complete evening homework tasks.
Clearance and return to play considerations
One of the most important areas of concern for the team physician involves the decision-making process regarding clearance and return to play. For female athletes with disordered eating behaviours and health consequences related to those behaviours, the Female Athlete Triad: Cumulative Risk Assessment in the 2014 Female Athlete Triad Coalition Consensus Statement on Treatment and Return to Play of the Female Athlete Triad can serve as a guide to physicians making clearance and return to play decisions (table 4).51 The risk assessment tool takes into account: dietary restriction, BMI, menstrual history (delayed menarche, oligomenorrhoea, amenorrhoea), bone mineral density and history of stress reaction or fracture. Each risk factor carries a point value, and the numeric score suggests whether an athlete should receive full clearance, provisional/limited clearance or restriction from participation (see table 5).51 While this risk assessment tool can help to guide clearance and return to play decisions for athletes with disordered eating and eating disorders, physicians should combine these recommendations with their own clinical decision-making skills, and need not use the tool in isolation. Of note, athletes diagnosed with anorexia nervosa who have a BMI <16 kg/m2 or athletes with moderate-to-severe bulimia nervosa (purging >4 times/week) should be categorically restricted from training and competition. Female athletes who fall into moderate and high- risk categories should have a written contract completed and signed by the athlete and each member of the multidisciplinary team.51 (figure 2).
While a similar evidence-based scoring system with concomitant clearance recommendations has not yet been developed for male athletes, the IOC has proposed a return to play model based on a red light (high risk), yellow light (moderate risk), green light (low risk) system.78
Efforts to prevent disordered eating behaviour among athletes should be aimed at athletes, coaches, athletic administrators and parents. Primary prevention efforts work to expand athlete knowledge about healthy eating, pathological eating behaviours and their consequences, and what to do if you or a teammate are thought to have an eating disorder.52 ,79 Athletes should be educated that dietary restriction and/or purging behaviour in pursuit of optimal weight and body composition will negatively impact sport performance and result in adverse health consequences. In one study, a peer-led educational programme for athletes resulted in improved bulimic pathology even 1 year after the intervention, and researchers noted an increase in the number of athletes who sought medical care because they had become concerned that they might have symptoms of the Female Athlete Triad.80 Likewise, athletes, coaches and parents should be informed that the loss of menstruation is not a positive adaptation to high-intensity training and sport participation, and represents a state of low energy availability stemming from either intentional or unintentional dietary restriction.51 Studies have shown that educational programmes directed at coaches are successful in increasing their knowledge about eating disorders in athletes, including recognition and management.81 However, it is not yet clear whether this increased awareness translates to improved outcomes among athletes.
The National Collegiate Athletic Association (NCAA) has developed educational materials for coaches, athletic administrators and athletes in an effort to prevent eating disorders.82 They identify 10 strategies for coaches and administrators, which aim to reduce the likelihood of disordered eating and eating disorders among their athletes:83
Be aware of the symptoms of disordered eating.
Consult a registered dietitian who specialises in sport, particularly a Board Certified Specialist in Sports Dietetics (CSSD) to prescribe appropriate nutrition for optimal sport performance.
De-emphasise weight: Be aware of how you are communicating to athletes about weight and performance. Focus on ways for athletes to enhance their performance that do not involve weight.
Keep an open dialogue with athletes about the importance of nutrition and staying injury-free for optimal athletic performance.
Recognise that the body composition and training required for optimal health and performance are not identical for all athletes.
Screen student-athletes before the start of the season for risk factors of disordered eating using a validated screening instrument.
Ensure that all stakeholders (coaches, strength and conditioning coaches, athletic trainers, student-athletes, student-athlete affairs administrators and athletics department staff) are educated about the factors that put athletes at risk for disordered eating.
Understand your institution's referral protocol for student-athletes who are in need of assistance with nutrition or disordered eating issues.
Encourage help-seeking for all mental health concerns, including disordered eating.
Develop a plan with other stakeholders (such as university counselling services or a sports registered dietitian) for how to identify and treat student-athletes with eating disorders.
Finally, sports medicine physicians should use the preparticipation evaluation as an opportunity to educate the parents of younger athletes about disordered eating and common health consequences. Emphasising the role of nutrition in optimising performance and health is an important strategy to avoid unhealthy dietary manipulation.
Eating disorders are devastating psychiatric conditions. They have an unacceptably high mortality rate and invoke considerable morbidity among those affected. Athletes are at greater risk for eating disorders given the pressure to achieve a body composition that optimises performance. While females are affected more commonly than males (at nearly a 9:1 ratio),1 ,2 both sexes are at greatest risk for eating disorder in sports where leanness confers a competitive advantage.12 ,13
Athlete medical teams need to systematically screen athletes (both male and female) as a part of the preparticipation evaluation. Once diagnosed, referral to an experienced multidisciplinary team is considered best practice. In addition to the team physician, dietitian and mental health professional, athletic trainers play a key role as the ‘eyes and ears’ of the healthcare team on the practice field and in the training room and oftentimes serve as the confidant and support person for the athlete who is struggling with and recovering from an eating disorder.
Sports medicine physicians play a key role in evaluation, diagnosis and treatment, including clearance and return to play. Utilising established recommendations that guide clearance and return to play decision-making can ease difficult decisions, and promote transparency and accountability in support of a healthy athlete.
