Extreme disorders dangerous
Dr Rebecca Cashmore is a consultant psychiatrist with the eating disorders team at the Leicestershire Partnership NHS Trust.
She said anorexia nervosa and bulimia were at the extreme ends of a spectrum of eating disorders she and her colleagues see among patients.
Dr Cashmore said: "The range of disorders covers people who are obsessive about their weight and shape and may use the control of eating to manage stress and emotions.
"The majority of people we see are treated as outpatients.

"A few who have very low weight come in as inpatients so that we can help with nutritional support and psychotherapy to help put them back on track.
"While the majority of those affected by anorexia are women, about one in 10 patients are men.
"Some people are more prone to suffering from eating disorders.
"They are maybe those people who set themselves very high standards or have underlying issues with their self esteem."
There is a 14-bed inpatient unit for people with eating disorders at the Brandon Unit at Leicester General Hospital.
It caters for patients from across the East Midlands.
However, new accommodation is being provided on the Glenfield Hospital site and the service is due to move in April.
Dr Cashmore said: "The patients will all have their own rooms and some will have en-suite facilities.
"It will be so much more modern."
Patients being treated in Leicestershire are also benefiting from research into anorexia nervosa.
Doctors at the partnership trust are working with colleagues at Loughborough University into researching treatment for people suffering from anorexia nervosa who compulsively exercise.
