Consider Eating Disorders in the Differential Diagnosis of Acute Abdomen in the Ages of Adolescence

An adolescent girl applied to the pediatric emergency outpatient clinic with a complaint of acute abdomen. On abdominal ultrasonography, it was suspected of intussusception. However, when her medical history was expanded, it was discovered that she had a recent eating episode followed by multiple vomiting and had lost weight because of an intense food restriction causing severe constipation. Briefly, we presented an adolescent eating disorder patient who clinically mimics acute abdomen due to secondary hypokalemia, hypomotility, and constipation.
