Understanding Bulimia Nervosa

Bulimia nervosa is a condition characterised by binge eating usually followed by some form of purging. It affects 1-2% of adolescent and young adult women.

Individuals experience a sense of lack of control over volume of food intake or food intake within short time frames which is followed by inappropriate behaviour to prevent weight gain such as self-induced vomiting, misuse of laxatives and diuretics, fasting or excessive exercise.
Self-evaluation is excessively influenced by body shape and weight.
People struggling with bulimia nervosa usually appear to be of average body weight.

Consequences of Bulimia Nervosa include:
  • Menstrual irregularities
  • Metabolic alkalosis
  • Electrolyte imbalance
  • Constipation/diarrhoea
  • Acid reflux and esophagitis
  • Dental erosion
  • Anxiety and depressed mood
  • Low self-esteem
  • Irritability

Causes of Bulimia nervosa
Personality: low self-esteem, fear of becoming fat, sensitivity to rejection, perfectionism
Genetic and environmental factors
Biochemistry: serotonin and noradrenaline activity are lower in patients with Bulimia nervosa. The abnormal levels could be a result, rather than cause, of the behavior.
