Idiopathic Anaphylaxis and Undiagnosed Anorexia Nervosa

This report describes an association between anorexia nervosa and idiopathic anaphylaxis. While eating disorders affect 0.6% of the population1, and idiopathic anaphylaxis occurs in approximately 1 in 10,000 individuals2 an association between anorexia nervosa and mast cell dysfunction has not previously been described. Features of anorexia nervosa include restriction of eating and energy intake, intense fear of gaining weight, and distorted perception of body weight and shape.1 We describe a fourteen-year-old girl with a history of well controlled hypothyroidism who developed sudden lip and eyelid edema, abdominal pain, stool urgency, lethargy, diarrhea, vomiting, throat tightness, and presyncope.
