Early in my career, I did not immediately recognize binge eating as a behavior that could carry acute medical risk. Learning about acute gastric dilatation changed that perspective.
Many clinicians associate binge eating primarily with long-term metabolic consequences. Yet a binge episode may precede acute massive gastric dilatation — a potentially life-threatening condition requiring urgent medical intervention.
This complication has been reported in patients with eating disorders as well as in individuals with no prior eating disorder history. Failure to consider the condition promptly can lead to serious consequences, including death.
Binge Eating May Not Be Disclosed
Recognizing binge eating in clinical settings can be challenging because patients may not disclose the behavior.
In a qualitative study of psychotherapy clients who concealed eating or body image concerns, many described seeking treatment for other issues — most commonly depression or anxiety — while leaving eating-related problems unspoken. Shame, including fear of the therapist’s judgment, was the most frequently cited reason for nondisclosure.
Research suggests that individuals often avoid discussing eating and body image struggles in healthcare settings, particularly when they anticipate weight stigma. As a result, binge eating and other eating disorder behaviors can remain unidentified unless clinicians ask directly and create conditions that reduce shame.
One approach my psychotherapypatients have suggested medical providers can take to lower this barrier is to focus clinical guidance on behaviors and health rather than weight.
Binge Eating Can Occur at Any Body Size
Binge eating episodes can occur at any body size. Clinical eating disorders — including binge-eating disorder, bulimia nervosa, anorexia nervosa, and atypical anorexia nervosa (anorexia in a not-emaciated body) — also span the weight spectrum.
However, stereotypes and the long-standing focus on emaciated presentations of anorexia nervosa have shaped assumptions about how people with eating disorders might look. In the case of binge eating, reliance on physical appearance can delay recognition of risk and potential acute complications.
Published case reports demonstrate that acute gastric dilatation can arise in a range of clinical contexts.
Illustrative Case Examples
No Known Eating Disorder
A 17-year-old boy presented with acute abdominal pain and distension after fasting for approximately 24 hours (reportedly for religious reasons) and then consuming a large meal. Imaging revealed massive gastric dilatation. Emergency laparotomy demonstrated a gangrenous, necrotic stomach with perforation requiring surgical management.
High-Volume Eating Environment
A 28-year-old woman presented with diffuse abdominal pain, nausea, and inability to vomit after consuming five meals within 3 hours at a food festival. Imaging demonstrated severe gastric distension consistent with acute gastric dilatation. She initially left the hospital against medical advice due to concerns over medical expenses but returned hours later with persistent symptoms, including constant nausea, inability to vomit, and obstipation. Her clinical course was complicated by gastric necrosis and perforation, requiring multiple laparotomies during a prolonged hospitalization.
History of Atypical Anorexia Nervosa
A 16-year-old girl presented with acute gastric dilatation after a binge episode. She had a history of obesity followed by atypical anorexia nervosa but no longer met diagnostic criteria at presentation. Daily binge eating had occurred for approximately 1 month prior. Surgical treatment was required.
History of Anorexia Nervosa
A 26-year-old woman presented with severe abdominal pain, nausea, and inability to vomit for approximately 2 hours. She initially reported consuming four beers and a Cobb salad. Imaging revealed acute massive gastric dilatation, and surgical intervention removed approximately two gallons of partially digested food. She later disclosed a history of anorexia nervosa and a preceding binge episode.
Bulimia Nervosa
A 22-year-old woman presented with abdominal pain and vomiting after a binge eating episode. Massive gastric dilatation was identified, and decompression removed approximately 11 liters of gastric contents. She died approximately 36 hours postoperatively from related complications. A history of recurrent bulimic episodes was disclosed by family members following her death.
Clinical Implications
I spoke with Jennifer Gaudiani, MD, internationally recognized expert on this topic, and author of Sick Enough: A Guide to the Medical Complications of Eating Disorders and Undernutrition.
She noted that symptom severity does not always reflect medical risk, explaining, “I’ve taken care of patients who experience excruciating abdominal pain yet who have normal imaging, and others whose massive gastric dilatation — definitely a surgical emergency — is found incidentally on imaging done for other reasons. They maybe had mild nausea at most.”
Dr Gaudiani emphasized that clinicians cannot rely on symptoms alone to determine safety.
“Binge eating can cause gastric dilatation, especially when patients have underlying gastroparesis, or slowed stomach emptying, due to undernutrition or other causes,” she said. “Patients, loved ones, and clinicians should have a high index of suspicion. A simple x-ray can diagnose this problem.”
Conclusion
Patients benefit when clinicians remain alert to acute abdominal pain following large food intake, whether or not a history of an eating disorder is disclosed.
Individuals at risk for gastric dilatation do not have a consistent or recognizable appearance and therefore may hide in plain sight. Early recognition and intervention can be lifesaving.
