'Bigorexia': Muscle dysmorphia 'now affects one in 10 gym-going men'
Muscle dysmorphia, also known as "bigorexia", may now be affecting one in 10 men who visit gyms in the UK, according to the Body Dysmorphic Disorder Foundation.
It is an anxiety disorder which causes someone to see themselves as small, despite being big and muscular. It is sometimes described as a kind of "reverse anorexia".
The cause of muscle dysmorphia is not clear. The NHS states it may be genetic or caused by a chemical imbalance in the brain.
