ⓘ Muscle dysmorphia
Muscle dysmorphia is a subtype of the obsessive mental disorder body dysmorphic disorder, but is often also grouped with eating disorders. In muscle dysmorphia, which is sometimes called bigorexia ", megarexia ", or reverse anorexia ", the delusional or exaggerated belief is that ones own body is too small, too skinny, insufficiently muscular, or insufficiently lean, although in most cases, the individuals build is normal or even exceptionally large and muscular already.
Muscle dysmorphia affects mostly males, particularly those involved in sports where body size or weight are competitive factors, becoming rationales to gain muscle or become leaner. The quest to seemingly fix ones body consumes inordinate time, attention, and resources, as on exercise routines, dietary regimens, and nutritional supplementation, while use of anabolic steroids is also common. Other body-dysmorphic preoccupations that are not muscle-dysmorphic are usually present as well.
Although likened to anorexia nervosa, muscle dysmorphia is especially difficult to recognize, since awareness of it is scarce and persons experiencing muscle dysmorphia typically remain healthy looking. The distress and distraction of muscle dysmorphia provoke absences from school, work, and social settings. Compared to other body dysmorphic disorders, rates of suicide attempts are especially high with muscle dysmorphia. Researchers believe that muscle dysmorphias incidence is rising, partly due to the recent cultural emphasis on muscular male bodies.
1. Signs and symptoms
Although body dissatisfaction has been found in males as young as age six, muscle dysmorphias onset is estimated at usually between ages 18 and 20. According to DSM-5, muscle dysmorphia is indicated by the diagnostic criteria for body dysmorphic disorder via "the idea that his or her body is too small or insufficiently muscular", and this specifier holds even if the individual is preoccupied with other body areas, too, as is often the case.
Psychologists have identified further clinical features of muscle dysmorphia, such as excess engagement in activities to increase muscularity, activities such as dietary restriction, over-exercise, and injection of growth-enhancing drugs. Persons experiencing muscle dysmorphia generally spend over three hours daily pondering increased muscularity, and feel unable to limit their weightlifting activities. As in anorexia nervosa, the reverse quest in muscle dysmorphia can be insatiable. Those suffering from the disorder closely monitor their body and may falsify its appearance by wearing multiple clothing layers to appear larger.
Muscle dysmorphia involves severe distress at having ones body viewed by others. Occupational and social functioning are impaired, and dietary regimes may interfere. Patients often avoid activities, people, and places to conceal their perceived deficiency of size or muscularity. Roughly half of patients have poor or no insight that these perceptions are unrealistic. Patient histories reveal elevated rates of diagnoses of other mental disorders, including eating disorders, mood disorders, anxiety disorders, and substance use disorder, as well as elevated rates of suicide attempts.
2.1. Risk factors Trauma and bullying
Versus the general population, persons manifesting muscle dysmorphia are more likely to have experienced or observed traumatic events like sexual assault or domestic violence, or to have sustained adolescent bullying and ridicule for perceived deficiencies such as smallness, weakness, poor athleticism, or intellectual inferiority. Increased body mass may seem to reduce the threat of further mistreatment.
2.2. Risk factors Sociopsychological traits
Low self-esteem associates with higher levels of body dissatisfaction and of muscle dysmorphia. Increased body size or muscularity may seem to enhance the masculine identity.
2.3. Risk factors Media exposure
As Western media emphasizes physical attractiveness, some marketing campaigns now exploit male body-image insecurities. Over the past 20 years, the number of mens-fitness magazines and of partially-undressed, well-muscled men in advertisements have increased. Such media provoke bodily comparisons and pressure individuals to conform, yet increase the gap between mens perceptions of their own muscularity versus their desired muscularity. In college-aged men, a strong predictor of a muscularity quest is internalization of the idealized male bodies depicted in media.
2.4. Risk factors Athletic participation
Athletes tend to share some psychological factors that may predispose to muscle dysmorphia, factors including high levels of competitiveness, need for control, and perfectionism, and athletes tend to be more critical of their own bodies and body weight. Athletes who also fail to achieve performance standards may resort to the extreme body-modifying measures of muscle dysmorphia. Involvement in sports where size, strength, and weight raise competitive advantage or lessen disadvantage, associates with muscle dysmorphia. Athletic ideals reinforce the social ideal of muscularity. Conversely, those already disposed to muscle dysmorphia may be more likely to participate in such sports.
Treatment of muscle dysmorphia can be stymied by a patients unawareness that the preoccupation is disordered or by avoidance of treatment. Scientific research on treatment of muscle dysmorphia is limited, the evidence largely in case reports and anecdotes, and no specific protocols have been validated. Still, evidence supports the efficacy of family-based therapy, cognitive behavioural therapy, and pharmacotherapy with selective serotonin reuptake inhibitors. Also limited is research on prognosis of the untreated.
Prevalence estimates for muscle dysmorphia have greatly varied, ranging from 1% to 54% of men in the studied samples. Samples of gym members, weightlifters, and bodybuilders show higher prevalence than do samples from the general population. Rates even higher have been found in users of anabolic steroids. The disorder is rare in women but does occur, and has been noted especially in female bodybuilders who have experienced sexual assault. Crossing cultures, muscle dysmorphia has been identified in populations in China, South Africa, and Latin America. Nonwestern populations less exposed to western media show a lower rate of muscle dysmorphia.
Muscle dysmorphia was first conceptualized by healthcare professionals in the late 1990s. In 2016, 50% of peer-reviewed articles on it had been published in the prior five years.
Although muscle dysmorphia was initially viewed as anorexia nervosas inverse - questing not to be small and thin, but to be large and muscular - later researchers fit the subjective experience to body dysmorphic disorder. Some debate continues.
The American Psychiatric Association recognized muscle dysmorphia in 2013 with the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders. This DSM-5 classifies it under body dysmorphic disorder. Muscle dysmorphia is absent from the International Statistical Classification of Diseases and Related Health Problems present edition, the tenth, published in 1992.
Muscle dysmorphias classification has been widely debated, and alternative DSM classifications have been proposed.
- Behavioral addiction: Some researchers seek muscle dysmorphias reclassification as a behavioral addiction. Muscle dysmorphias effort to maintain body image is enacted through activities such as exercise, diet, and related shopping, which may cause conflicts with others. Moreover, compulsive muscle building and dietary restriction can escalate these conflicts. Further, abstinence from these activities can provoke withdrawal symptoms, returning the individual to compulsive behavior.
- Eating disorder: Many of muscle dysmorphias traits overlap with those of eating disorders, including focus on body weight, shape, and modification, whereas body dysmorphic disorder otherwise usually lacks such dietary and exercise components. Also, persons experiencing muscle dysmorphia tend to score high on the Eating Attitudes Test and Eating Disorder Inventory, while muscle dysmorphia and anorexia nervosa share diagnostic crossover. Muscle dysmorphia and disordered eating correlate more to each other than either correlates to body dysmorphic disorder. Treatment for eating disorders may also be effective for muscle dysmorphia.
