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
- Acid reflux and esophagitis
- Dental erosion
- Anxiety and depressed mood
- Low self-esteem
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.
