The stomachs of competitive eaters accommodate large quantities of food by repeated rapid distension of the gastric wall during eating episodes. A Clinical Challenges and Images in GI article in the June issue of Gastroenterology presents an adverse outcome of these competitions.
Tian-Zhi Lim et al describe the case of a 30-year-old, healthy man who arrived at the emergency department with abdominal pain and distension 8 hrs after a competitive speed eating event, at which he consumed a 3.2-kg burger (about 7 lbs) in 30 minutes. The patient had vomitus that was nonbloody and nonbilious, comprising undigested food materials.
Extreme overeating can cause gastroparesis, aspiration pneumonia, GI bleeding, Mallory-Weiss tear, Boerhaave syndrome, and morbid obesity. Lim et al discourage these these competitions, stating that they test the limits of human health.
