Dumping syndrome is a medical condition that occurs when food moves too quickly from the stomach to the small intestine. It is often associated with gastric surgery, such as a gastric bypass or gastrectomy. Symptoms of dumping syndrome vary, but can include abdominal cramping, nausea, vomiting, diarrhoea, lightheadedness, rapid heart rate, and sweating after eating. It is important to recognize the signs and symptoms of dumping syndrome in order to properly diagnose and treat the condition. The primary cause of dumping syndrome is thought to be a disruption of the normal digestive process. In a healthy person, food is slowly digested in the stomach before moving to the small intestine. However, after gastric surgery, food can move quickly to the small intestine, where it is not adequately digested. This causes a sudden surge of sugar in the bloodstream, triggering a number of uncomfortable symptoms. Certain foods can make dumping syndrome worse, so it is important to avoid them. These include sugary foods, processed foods, high-fat foods, and large amounts of food or fluids at one time. Eating several small meals throughout the day, rather than large meals, can help to prevent dumping syndrome. Treatment of dumping syndrome typically involves dietary changes and medications.
