Teenage boys who admit using muscle-building supplements should be sent to a psychologist to check whether they have an eating disorder, according to new guidance for GPs.
Mental health experts have told GPs to look out for young adults who consume protein or creatine powders to give their workouts a boost and quickly build muscle mass.
They fear the habit could be an early sign of body dysmorphia – a disorder that causes sufferers to agonise over self-perceived flaws in their appearance.
Typically beginning in early adolescence, the mental health condition can lead to anorexia and even suicidal thoughts.
Powders such as whey protein and creatine monohydrate have become increasingly popular as dietary supplements for those seeking to improve their athletic performance and strength.
They are mixed into smoothies after workouts to help build and repair tired muscles.
The guidelines, published by researchers at the University of Toronto, advise doctors to refer teenage patients who report using supplements for a full psychological assessment.
Researcher and eating disorder expert Kyle T. Ganson says GPs should question patients about the supplements they use – and ask why they are motivated to use them.
Psychologists have also warned that the extreme dieting habits associated with muscle-building could be causing physical harm to young men.
The over-consumption of protein can damage organs, including the kidneys and intestines.
By discussing the potential for a fitness obsession to become an eating disorder, Mr Ganson explains, GPs can better understand their patients’ motivations and educate them on the risks of their behaviour.
‘The goal is to provide strategies to reduce negative effects… while acknowledging that abstinence [from powders] may not be a realistic goal for all clients,’ he adds.
