, RATIONALE: This set of symptoms aligns with anorexia nervosa because it encompasses both the physical
manifestations of severe malnutrition, such as bradycardia and hypothermia, as well as the psychological and behavioral
characteristics, like intense fear of gaining weight and distorted body image, which are hallmarks of the disorder. The
presence of lanugo, a sign of malnutrition, and amenorrhea, a marker of hormonal imbalance, further supports the
diagnosis of anorexia nervosa.

erosion, enlarged parotid glands, calluses(Russell's sign).

weight gain, which is evident in the provided symptoms such as vomiting and laxative use. The combination of these
behaviors, despite maintaining a normal or slightly low weight, and physical signs like dental erosion and enlarged
parotid glands, is a hallmark of bulimia nervosa and distinguishes it from other eating disorders.

description of signs of binge-eating disorder because it accurately identifies the key characteristics of the condition,
including the occurrence of recurring episodes of excessive food consumption without purging, increased risk of obesity,
and feelings of guilt or shame after episodes.
This description is specific to binge-eating disorder, as it distinguishes it from other eating disorders such as bulimia
nervosa, which typically involves purging behaviors.
