Bulimia nervosa

Bulimia nervosa is a syndrome characterized by recurrent bulimia and a strong preemptive concept of weight control, which leads patients to take extreme measures to weaken the ldquo; fat rdquo; effect of the food they eat. Anorexia nervosa and bulimia nervosa are both weird behavioral eating diseases. Although the clinical manifestations and prognosis of the two are different, the root cause and the essence of the disease are the same and both originate from the fear of obesity. Therefore, some people regard these two diseases as different manifestations of the same disease. Both diseases occur in young women. As early as 1959, Stunkard in the United States reported the phenomenon of overeating, followed by vomiting and catharsis among obese and normal weight people, and called it ldquo; Eating Syndrome rdquo; Disease rdquo ;. The term ldquo; bulimia nervosardquo; was first proposed by Russell in the United Kingdom in 1979, and was gradually accepted by the public. At present, there is an independent classification and diagnosis standard for the disease, but the relationship with anorexia nervosa is still divided.
