Anorexia and bulimia is affecting an increasing number of men, experts have warned.
Healthcare professionals have been urged to identify possible cases among males, who are often reluctant to admit a problem normally associated with teenage girls.
NHS figures back up the concerns, with a 66% increase in hospital admissions for male eating disorders over the last 10 years.
The rise in male eating disorders has been blamed on increasing pressure on men to look good.
The eating disorder charity Beat said men’s reluctance to be open about their health is hampering efforts to address the problem.
A spokesman said: “We need GPs to be much more aware of the fact that males also these days are experiencing problems with eating disorders. They are not as good at recognising the symptoms in men as they should be.”
