Dumping syndrome is a condition that can develop after surgery to remove all or part of your stomach or after surgery to bypass your stomach to help you lose weight. Also called rapid gastric emptying, dumping syndrome occurs when food, especially sugar, moves from your stomach into your small bowel too quickly. Most people with dumping syndrome develop signs and symptoms, such as abdominal cramps and diarrhea, 10 to 30 minutes after eating. Other people have symptoms one to three hours after eating, and still others have both early and late symptoms. Signs and symptoms of dumping syndrome generally occur right after eating, especially after a meal rich.
• Abdominal cramps
• Dizziness, lightheadedness
• Rapid heart rate
Late dumping signs and symptoms, which occur one to three hours after eating, are due to your body releasing large amounts of insulin to absorb the large amount of sugars entering your small intestine after you eat a high-sugar meal.
The disorder is diagnosed through medical evaluation of medical history of the patient, by observing the blood-sugar levels and by performing gastric emptying test where a radioactive material is added to food to measure how quickly food moves through your stomach.
Early dumping syndrome is likely to resolve on its own within three months. In the meantime, there's a good chance that diet changes will ease your symptoms. If not, your doctor may recommend medications or surgery. Octreotide is used to treat the disorder.Sometimes anti-diarrhoeals are also used in the treatment regimen.
The incidence and severity of symptoms in dumping syndrome are related directly to the extent of gastric surgery. An estimated 25-50% of all patients who have undergone gastric surgery have some symptoms of dumping. However, only 1-5% are reported to have severe disabling symptoms.
