What is dumping syndrome?

Dumping syndrome is a problem caused by rapid emptying of the stomach, characterized by nausea, diarrhea, and fatigue after eating. Oral food and beverages go from the stomach to the duodenum. If this transition is accelerated and the high carbohydrate content reaches the small intestine quickly, occurs. This problem can occur in patients who have had gastric bypass surgery when high levels of simple carbohydrates are ingested. The condition can also develop in people who have had esophageal surgery. About 20 percent of patients develop clinically significant dumping symptoms after pyloroplasty or distal gastrectomy. Patients younger than 35 years of age or with a BMI <25 kg/m 2 are more likely to be symptomatic than patients who are older or more obese.


Dumping syndrome symptoms can be divided into those that occur early after eating or in the later period. Early symptoms are those that appear within 10 to 30 minutes of eating. After 10-30 minutes after eating, people experience abdominal pain, cramps in the abdomen and diarrhea.

Dumping syndrome occurs especially if the meal is rich in table sugar (sucrose) or fruit sugar (fructose). Usually, early dumping is self-limiting and resolves within 7 to 12 weeks. It is possible to list the symptoms as follows:
