<unk>  is an eating<unk>  characterized by the DSM-5 as self-induced vomiting, misuse of laxatives, diuretics, or enemas to forcefully evacuate matter from the body.<unk>  differs from bulimia nervosa (BN) because individuals do not consume a large amount of food before they purge. In current diagnostic systems,<unk>  is a form of other specified feeding or eating<unk> . Research indicates that<unk> , while not rare, is not as commonly found as anorexia nervosa or bulimia nervosa. This syndrome is associated with clinically significant levels of distress, and that it appears to be distinct from bulimia nervosa on measures of hunger and ability to control food intake. Some of the signs of<unk>  are frequent trips to the bathroom directly after a meal, frequent use of laxatives, and obsession over one's appearance and weight. Other signs include swollen cheeks, popped blood vessels in the eyes, and clear teeth which are all signs of excessive vomiting.<unk>  is studied far less often than anorexia nervosa and bulimia nervosa as it is not considered an independent diagnosis in the DSM-5, published in 2013. However, it has been argued that<unk>  should be considered a distinct eating<unk> , separate from bulimia nervosa. Because of this, little information is known about the risk factors for<unk> , including how gender, race, and class could contribute to the risk for<unk> . As with most eating<unk> s, it is suggested that<unk>  is gender specific because of cultural forces and social pressures. These social pressures are associated with a severe preoccupation with shape and weight, this puts women and transgender individuals at the most risk for eating<unk> s, including<unk> . In one study of the risk factors for<unk>  77% of the participants who presented with symptoms of<unk>  were female.<unk>  progressing into bulimia nervosa has been observed, while it is extremely rare for the reverse situation, bulimia nervosa progressing into<unk> . This was observed once in a transgender patient with a severe history of bulimia nervosa but presented with symptoms of<unk>  to an eating<unk>  treatment facility in New Zealand. Estimates of lifetime prevalence of<unk>  have been estimated from 1.1% to 5.3%.
