This page talks about bulimia nervosa and provides information on warning signs, the physical effects, and treatment and recovery options.

What is bulimia nervosa?

Bulimia nervosa is a serious psychiatric illness characterised by recurrent binge-eating episodes (the consumption of abnormally large amounts of food in a short period of time), followed by self-induced vomiting, fasting, over-exercising and/or the misuse of laxatives, enemas or diuretics.

Bulimia nervosa differs from binge eating disorder (BED). While binge episodes in both illnesses are associated with a sense of loss of control and are followed by feelings of guilt and shame, a person experiencing bulimia nervosa will immediately engage in compensatory behaviours such a vomiting or exercise.

A person with bulimia nervosa can be of any body shape, size or weight.

Did you know?

Bulimia nervosa often starts with weight-loss dieting. The resulting food deprivation and inadequate nutrition can trigger what is, in effect, a starvation reaction — an overriding urge to eat. For some, the desire to eat is uncontrollable, leading to a substantial binge on whatever food is available, followed by compensatory behaviours. A repeat of this behaviour often follows, leading to a binge/purge/exercise cycle, which can become more compulsive over time.

Warning signs of bulimia nervosa

 Some of the more common signs and symptoms of bulimia nervosa are:

  • Difficulties with activities that involve food
  • Loneliness due to self-imposed isolation and a reluctance to develop personal relationships
  • Deceptive behaviours relating to food
  • Fear of the disapproval of others if the illness becomes known
  • Mood swings, changes in personality, emotional outbursts or depression
  • Self-harm, substance abuse or suicide attempts
  • Sensitivity to references about weight or appearance
  • Guilt, self-disgust, self-loathing
  • Anxiety
  • Depression
  • Frequent trips to the bathroom, especially after eating
  • Signs of damage due to vomiting including swelling around the cheeks or jaw, calluses on knuckles, damage to teeth and bad breath
  • Food avoidance, dieting behaviour (this may be due to a fear of gaining weight and it may also be to avoid the unpleasant ritual of purging afterwards)
  • Fluctuations in weight

Bulimia nervosa can often be missed by health professionals and can go undetected for a long period of time.
