People with bulimia nervosa consume large amounts of food and then rid their bodies of the excess calories by vomiting, abusing laxatives or diuretics, taking enemas, or exercising obsessively. Some use a combination of all these forms of purging. Because many individuals with bulimia “binge and purge” in secret and maintain normal or above normal body weight, they can often successfully hide their problem from others for years.
Now, according to 2013 DSM-5, these specifiers no longer exist (remain listed here for historical/informational purposes only). The deletion of the purging/non-purging specifier types was made with the rationale that compensatory behaviors may change from purging (e.g., using laxatives) to non-purging forms (e.g., extreme dieting) within the same individual over the course of the disorder.
