Identification

What are they?

Eating disorders: Anorexia Nervosa, Bulimia Nervosa and Binge Eating Disorder (compulsive over-eating) are serious mental illnesses affecting 1.6 million people in the UK. They are most likely to develop during teenage years and although more girls are affected, around a quarter of those who experience an eating disorder at school age are boys.

What signs and symptoms
indicate an eating disorder?

A specialist will need to diagnose an eating disorder but some
signs include those listed in the tables below.

1. Anorexia Nervosa

Anorexia Nervosa is an illness where there is a clinically established weight loss, measured either using the Body Mass Index (BMI) or weight and height criteria. There is a relentless aim for weight loss, mainly through restricted eating; excessive exercise and other behaviours aimed at weight control may also occur.

  • 1. Physical
    • Feeling tired- finding it harder to do all the things you usually do and having low immunity.
    • In girls, absence of three or more consecutive periods.

4. Other Eating Related Disorders

There are also other forms of disordered eating. Although these are not formally categorised as Eating Disorders, they are worth managing early in order to prevent them from developing into full-blown eating disorders.

  • Food Phobias
    • These include fear and avoidance of certain groups of food either due to bad association with food/eating or due to a fear of vomiting.
  • Body Dysmorphic Disorder
    • In this condition, there is an obsessive and distorted focus on how a part or the whole body is viewed.
  • Exercise Addiction
    • This is when the need to exercise becomes compulsive or has no flexibility. There is a relentless pursuit of exercise, daily, whether tired or not. There is a fear of altering or reducing exercise. There is an increase in the number of repetitions of an exercise, eg. stomach curls; using the machines that burn the most amount of calories. There is a pattern of increasing physical activity due to increasing tolerance of effort.
    • Exercise addiction occurs in both boys and girls but may be more common in boys. Sometimes in boys, exercise addiction can lead to what has been termed ‘Bigorexia’ where, just as in Anorexia there is a relentless pursuit of thinness at all cost, in ‘Bigorexia’ there is a relentless pursuit of body building.
    • Obviously exercise in moderation is healthy, over-exercising can lead to many negative effects such as its effects on bones, potentially causing fractures. In women it can affect menstruation. It can also lead to irritability, anxiety and depression.
