Bulimia nervosa, often just called bulimia, is a disorder characterized by rapid, out-of-control binge-eating past the point of fullness or comfort, followed by purging.
Purging can take a couple of different forms: one is self-induced vomiting, performed by manually stimulating the gag reflex or drinking ipecac syrup; the other is defecation with the aid of laxatives or diuretics.
To fit the diagnosis, the cycle of binging and purging must be repeated consistently at least once a week for a period of 3 months, but can happen as often as multiple times per day.
The onset of bulimia typically happens around adolescence, usually in individuals with low self-esteem who have a strong desire to have control over key aspects of their life including their weight.
They are often fixated on food, including the amount of food they consume as well as the caloric and fat content of that food.
The pattern of bulimia is often cyclical, with someone setting unrealistic goals for themselves (like getting a 100 percent on every exam they take).
When they don’t reach those goals, they binge, and then they purge to try to “fix” the binging episode.
Individuals with bulimia will also try to control their weight in other ways—by taking stimulants, by going on extreme diets such as “water fasts” where they consume only water, and by exercising excessively.
These symptoms of binging and purging with bulimia nervosa can be confused with another eating disorder, anorexia nervosa, where they might also binge and purge.
The main distinction between these two disorders has nothing to do with this act of binging and purging; it’s actually defined by an individual's weight.
People with bulimia are usually normal weight or overweight, whereas people with anorexia are underweight.
Because of this, people can more easily hide the fact that they suffer from bulimia, and can also potentially start out with bulimia, which progresses into anorexia over time.
The binging and purging cycles associated with bulimia can result in a number of serious side effects.
Repeated vomiting can lead to erosion of dental enamel, sialadenosis (swelling of the parotid or salivary gland), and halitosis (very bad breath).
