Bulimia Nervosa is a serious, potentialy life-threatening eating disorder characterized by a secretive cycle of bingeing and purging.

• Eating large quantities of food in short periods of time, often secretly, without regard to feelings of "fullness" or "hunger," and to the point of feeling "out of control" while eating.
• Following these "binges" with some form of purging or compensatory behavior to make up for the excessive calories taken in:  self-induced vomiting, laxative or diuretic abuse, fasting, and/or obsessive or compulsive exercise.
• Extreme concern with body weight and shape.

• Bulimia nervosa affects 1-3% of middle and high school girls and 1-4% of college age women.
• Approximately 80% of bulimia nervosa patients are female (Gidwani, 1997).
• People struggling with bulimia nervosa will often appear to be of average body weight.
• Often, people struggling with bulimia nervosa will develop complex schedules or rituals to provide opportunities for binge-and-purge sessions.
• Many people struggling with bulimia nervosa recognize that their behaviors are unusual and perhaps dangerous to their health.

Bulimia nervosa can be extremely harmful to the body. The recurrent binge-and-purge cycles can affect the entire digestive system and can lead to electrolyte and chemical imbalances in the body that affect the heart and other major organ functions. Some of the health consequences of bulimia nervosa include:

• Electrolyte imbalances that can lead to irregular heartbeats and possibly heart failure and death. The electrolyte imbalances are caused by losses of potassium and sodium from the body and dehydration as a result of purging behaviors.
• Inflammation and possible rupture of the esophagus from frequent vomiting.
• Chronic irregular bowel movements and constipation as a result of laxative abuse.
• Tooth decay and staining from stomach acids released during frequent vomiting.
• Peptic ulcers and pancreatitis.
• Potential for gastric rupture during periods of bingeing.

The chances for recovery increase the earlier bulimia nervosa is detected  Therefore, it is important to be aware of some of the warning signs of bulimia nervosa.

• Evidence of binge-eating, including disappearance of large amounts of food in short periods of time or the existence of wrappers and containers indicating consumption of large amounts of food.
• Evidence of purging behaviors, including frequent trips to the bathroom after meals, signs and/or smells of vomiting, presence of wrappers or packages of laxatives or diuretics.
• Excessive, rigid exercise regimen--despite weather, fatigue, illness, and injury, the need to "burn off" calories taken in.
• Unusual swelling of the cheeks or jaw area.
• Calluses on the back of the hands and knuckles from self-induced vomiting.
• Discoloration, staining of the teeth.
• Creation of complex lifestyle schedules or rituals to make time for binge-and-purge-sessions.
• Withdrawal from usual friends and activities.
• In general, behaviors and attitudes indicating that weight loss, dieting, and control of food are becoming primary concerns.
