BULIMIA NERVOSA

Bulimia Nervosa | Overview
Bulimia nervosa is eating disorder that characterized by episodes of binge-eating that recur, uncontrolled and involve the ingestion of a large amount off foot in a short time. This binge eating is usually followed by some form of purging behavior such as vomiting and the excessive use of laxatives or diuretics.

Like anorexic, the clients with bulimia nervosa has an intense fear of fatness. This intense fear distinguishes the bulimic from people who binge-eat for pleasure or to reduce stress.

Some controversy exist about whether bulimia nervosa is separate syndrome from anorexia nervosa because the clinical manifestation of bulimia nervosa - binge eating and purging- occur in people at varied body weights ranging from starved to overweight.

Some client with anorexia nervosa maintain low weight by food restriction alone but others use purging behaviors to rid themselves of unwanted calories and at times indulge in an eating binge.

Normal weight bulimia nervosa client's who experience the binge-purge cycle frequently have a 10-pounds weight fluctuation. The height-weight bulimic experiences the binge-purge cycle and overlaps with the obese client who may binge-eat but purge or have a morbid fear of fatness

Bulimia Nervosa | Pathophysiology
The bulimia nervosa client's secretly eats enormous quantities of food - often concentrated sweets or fats - very rapidly without appreciating the taste. The onset of binge may be precipitated by a variety of factors such as hunger, boredom, anger, anxiety and depression

Eating bingers may also be triggered by physical causes that are not yet understood. Bouts of overeating may be provoked or facilitated by hypothalamic reactions to starvation.

Bulimic spend much of their day in a starved stated and may actually suffer from chronics malnutrition with resulting metabolic and endocrine symptoms of starvation.

Binger eating behavior usually results in feeling of depression and self-deprecating thoughts. Approximately half of the people with bulimia nervosa binge-eat daily or more often.

During a binge most bulimic consume far more calories than would be eaten in a normal meal. Binge-purge episodes are interspersed with periods of minimal food intakes and many bulimics do not eat normal meals.

Purging behaviors is an attempt to regain a senses of control and to eliminate the calories ingested. Most people with bulimia nervosa report that vomitting is their preferred method of purging
