Surgery that alters your stomach can increase your risk of dumping syndrome. These surgeries are most commonly performed to treat obesity, but are also  part of treatment for stomach cancer and other conditions. These surgeries include:

  • Gastrectomy, in which a portion or all of your stomach is removed.
  • Gastric bypass surgery (Roux-en-Y operation), which is performed to treat morbid obesity. It surgically creates a stomach pouch smaller than the stomach, meaning you're no longer able to eat as much as you once did. It connects the small intestine to this pouch in the form of a gastrojejunostomy.
  • Esophagectomy, where all or part of the tube between the mouth and the stomach is removed.
