Do you know what it means to have an eating disorder?
For reasons that are unclear, some people--mainly young women--develop potentially life-threatening eating disorders called bulimia nervosa and anorexia nervosa. People with bulimia, known as bulimics, indulge in bingeing (episodes of eating large amounts of food) and purging (getting rid of the food by vomiting or using laxatives). People with anorexia, whom doctors sometimes call anorectics, severely limit their food intake. About half of them also have bulimia symptoms.
The National Center for Health Statistics estimates that:
Once people begin bingeing and purging, usually in conjunction with a diet, the cycle easily gets out of control. While cases tend to develop during the teens or early 20s, many bulimics successfully hide their symptoms, thereby delaying help until they reach their 30s or 40s. Several years ago, actress Jane Fonda revealed she had been a secret bulimic from age 12 until her recovery at 35. She told of bingeing and purging up to 20 times a day.
While normal food intake for women and teenagers is 2,000 to 3,000 calories in a day, bulimic binges average about 3,400 calories in 1 1/4 hours, according to one study. Some bulimics consume up to 20,000 calories in binges lasting as long as eight hours. Some spend $50 or more a day on food and may resort to stealing food or money to support their obsession.
To lose the weight gained during a binge, bulimics begin purging by vomiting (by self-induced gagging or with an emetic, a substance that causes vomiting) or by using laxatives (50 to 100 tablets at a time), diuretics (drugs that increase urination), or enemas. Between binges, they may fast or exercise excessively.
Extreme purging rapidly upsets the body's balance of sodium, potassium, and other chemicals. This can cause

While anorexia most commonly begins in the teens, it can start at any age and has been reported from age 5 to 60. Incidence among 8- to 11-year-olds is said to be increasing.
Anorexia may be a single, limited episode with large weight loss within a few months followed by recovery. Or it may develop gradually and persist for years. The illness may go back and forth between getting better and getting worse. Or it may steadily get more severe.
Anorectics may exercise excessively. Their preoccupation with food usually prompts habits such as moving food about on the plate and cutting it into tiny pieces to prolong eating, and not eating with the family.
Obsessed with weight loss and fear of becoming fat, anorectics see normal folds of flesh as "fat" that must be eliminated. When the normal fat padding is lost, sitting or lying down brings discomfort not rest, making sleep difficult. As the disorder continues, victims may become isolated and withdraw from friends and family.
The body responds to starvation by slowing or stopping certain bodily processes. Here are some symptoms:
Reduced fat causes the body temperature to fall. Soft hair called lanugo forms on the skin for warmth. Body chemicals may get so imbalanced that heart failure occurs.
Anorectics who additionally binge and purge impair their health even further. The late recording artist Karen Carpenter, an anorectic who used syrup of ipecac to induce vomiting, died after buildup of the drug irreversibly damaged her heart.
Early treatment is vital. As either disorder becomes more entrenched, its damage becomes less reversible.
Usually, the family is asked to help in the treatment, which may include psychotherapy, nutrition counseling, behavior modification, and self-help groups. Therapy often lasts a year or more--on an outpatient basis unless life-threatening physical symptoms or severe psychological problems require hospitalization. If there is deterioration or no response to therapy, the patient (or parent or other advocate) may want to talk to the health professional about the plan of treatment.
There are no drugs approved specifically for bulimia or anorexia, but several, including some antidepressants, are being investigated for this use.
If you think a friend or family member has bulimia or anorexia, point out in a caring, nonjudgmental way the behavior you have observed and encourage the person to get medical help. If you think you have bulimia or anorexia, remember that you are not alone and that this is a health problem that requires professional help. As a first step, talk to your parents, family doctor, religious counselor, or school counselor or nurse.
