Prevalence of Muscle Dysmorphia
It is unknown what proportion of the population live with muscle dysmorphia. Men represent most of those affected. Like many other mental health conditions, muscle dysmorphia onset tends to occur in late adolescence and young adulthood, a time of significant physical and emotional change.
People with muscle dysmorphia may also have other mental health conditions, such as depression, anxiety disorders, eating disorders, Body Dysmorphic Disorder (BDD), Obsessive-Compulsive Disorder (OCD), or substance use disorders.
Muscle dysmorphia is a complex disorder, and likely results from multiple interactions between genetics, psychological and environment factors. Some studies suggest that muscle dysmorphia is closely related to eating disorders or OCD.
Adverse childhood experiences involving teasing or bullying can cultivate personal beliefs linking personal attractiveness with self-worth, possibly triggering muscle dysmorphia in the face of an adverse life stressor (e.g. relationship breakup).
The key symptom of muscle dysmorphia is a preoccupation with one’s level of muscularity.
Other symptoms include covering up their body, seeking frequent reassurance from others about their level of muscularity, avoiding social situations involving having to eat food one has not prepared themselves (e.g. at a wedding), or the use of anabolic steroids.
Case-report evidence shows that cognitive behavioural therapy (CBT) or family-based therapy (for adolescents) can be useful for managing muscle dysmorphia.
Medications used to treat BDD, including selective serotonin reuptake inhibitors (SSRIs), can also help.
