What is it?

Gastrectomies are performed due to gastric cancer, peptic ulcers, trauma or in order to control obesity. Due to this surgery, anatomical changes are made, resulting in changes in the stomach emptying time. The anatomical changes make the stomach less capable to retain for long enough for digestion to occur, and food travels down too quickly. This phenomenon is referred to as dumping syndrome. There is an early dumping syndrome, in which symptoms appear 30 minutes after eating a meal and a late dumping syndrome, in which the symptoms appear 2-4 hours after eating.
