Bulimia nervosa is characterized by recurrent episodes of binge eating followed by purging behaviors, such as self-induced vomiting, misuse of laxatives or diuretics, fasting, or obsessive exercise, in an attempt to prevent weight gain.
Bulimia occurs in adolescents and young adult women but is relatively uncommon in men, and typically develops in the late teens or early 20s. Fifty percent of bulimics have or had anorexia nervosa.
Some authorities believe that as many as 10 percent of women are affected over their lifetimes. Clinically speaking, a person with bulimia nervosa binges at least twice a week, eats large amounts of food in a relatively short period of time, and then purges to rid her body of the unwanted calories.
More than half of bulimics are severely depressed and often suffer from alcohol and drug abuse in addition to their eating problems. Unlike the anorexic, who is excessively thin, the bulimic’s weight is usually average or slightly above average and often fluctuates.
