Dumping syndrome is a condition characterized by the abnormally rapid emptying of stomach contents into the small intestine. This condition manifests with symptoms such as nausea, diarrhea, and post-meal fatigue, particularly after consuming high-carbohydrate foods.

The development of this syndrome is often associated with gastrointestinal operations such as gastric bypass surgery or esophageal surgeries. For instance, approximately 20% of patients undergoing pyloroplasty or distal gastrectomy may develop clinically significant dumping symptoms. Demographic factors also play a role; patients under 35 years of age or with a body mass index (BMI) below 25 kg/m² are more likely to be symptomatic compared to older patients or those with a higher BMI.
