is more common in women than in men. Bulimia generally starts at about 16 to 18 years of age. Any given woman has a 1-4% chance of developing this condition throughout her lifetime.
Bulimia is often found in association with other eating disorders such as anorexia nervosa.
Risk Factors for
There are few predisposing factors for the development of this eating disorder. The main risk factor of bulimia is a family history of psychiatric illness or a co-existing psychiatric problem. If another close family member has suffered from depression or eating disorder in the past, the risk of developing bulimia is increased.
If the patient has suffered or is suffering from depression, they are also more likely to develop an eating disorder. Whether this trend represents a genetic or environmental link is not entirely known.
Progression ofExcessive dieting by bulimia patients commonly have a history which progresses to bulimia-type behaviour (induced vomiting) with repeating diet failure. The patient will regularly engage in eating binges followed by the bulimia behaviours of vomiting and use of purgatives/laxatives to avoid the calorie content of the food.
Excessive vomiting and laxative induced diarrhoea may result in an electrolyte imbalance which could be potentially life-threatening if left untreated. Binge eating disorder is bulimia without the vomiting and other weight-reducing strategies.
How is Diagnosed?Without the occurrence of complications, investigations such as blood tests are not warranted for this bulimia.
Unless sufferers come forward with their condition it can be hard for even the closest of friends and family to see any signs completely out of the ordinary.
Prognosis of
Prognosis for is better than for anorexia nervosa. With treatment for bulimia, approximately 60% of patients will recover.
There is usually no requirement for hospital admission for bulimia illness sufferers, unless the patient is suffering from an electrolyte disturbance that can be induced by long-term vomiting and diarrhoea. It must be stressed that the electrolyte complications of bulimia can be life-threatening.
Bulimia treatment tends to focus on breaking the binge-purge cycles.
Patients will benefit most from psychotherapy in a number of settings. Individual and group psychotherapy have been proven to imporve the outcome of patients with . The use of anti-depressants such as fluoxetine, in combination with psychotherapy increases the overall outcome of this eating disorder.

Anorexia nervosa is a psychological disease.
Anorexia nervosa treatment can be conducted on an outpatient basis unless the weight loss is severe and accompanied by marked physical symptoms such as dizziness, weakness and/or electrolyte and vitamin disturbances. Hospital admission may then be unavoidable and may need to be on a medical ward initially. Rarely the patient's weight loss may be so severe as to be life-threatening. If the patient cannot be persuaded to enter hospital, compulsary admission may have to be used.
