What is Anorexia Nervosa?
Anorexia Nervosa is a psychological illness with devastating physical consequences. Anorexia Nervosa is characterised by low body weight and body image distortion with an obsessive fear of gaining weight which manifests itself through depriving the body of food. It often coincides with increased levels of exercise. There are two main sub-types of anorexia:
Restricting type: this is the most commonly known type of Anorexia Nervosa whereby a person severely restricts their food intake. Restriction may take many forms (e.g. maintaining very low calorie count; restricting types of food eaten; eating only one meal a day) and may follow obsessive and rigid rules (e.g. only eating food of one colour).
Binge-eating or purging type: less recognised; a person restricts their intake as above, but also during some bouts of restriction the person has regularly engaged in binge-eating OR purging behaviour (e.g. self induced vomiting, over-exercise, misuse of laxatives, diuretics or enemas).
Who gets Anorexia Nervosa?
Anorexia Nervosa usually develops during adolescence and generally has an earlier age of onset than Bulimia Nervosa and Binge Eating Disorder (the latter are often developed during late adolescence or early adulthood). However like all eating disorders, anorexia can develop at any age or stage of life for both males and females. It is a myth that only adolescent girls experience anorexia.
There is no single cause of anorexia but there are risk factors that increase the likelihood of anorexia developing. These can be cultural, biological or psychological.

Physical Signs and Effects of Anorexia Nervosa
Recovery and Treatment
Anorexia is the most fatal of all psychiatric illnesses. Extreme food restriction can lead to starvation, malnutrition and a dangerously low body weight – all of which are synonymous with a host of health problems. Anorexia has the highest mortality rate of any psychiatric disorder.
