Understanding Dumping Syndrome: Causes, Symptoms, & Management

Gastric sleeve surgery is a popular choice for people looking to manage obesity. While the results can be life-changing and has the longest evidence regarding safety and durability. Having said that there are some side effects to be mindful of, like dumping syndrome. This condition, often linked to gastric bypass, can also rarely happen after a gastric sleeve procedure.

Dumping syndrome can be uncomfortable, even distressing, but with the right approach, it can be managed effectively.

Let’s explore the symptoms and how you can handle them effectively, patients can continue their weight loss journey with more confidence and fewer interruptions.

What is Dumping Syndrome?

When food, especially sugar and carbohydrates, moves from the stomach into the small intestine too quickly, it can result in some symptoms, collectively known as “dumping syndrome.”

There are two variations, early or late dumping syndrome. While late dumping syndrome can develop 1-3 hours after a meal, early dumping syndrome typically happens within 10–30 minutes of eating. Patients may have varying degrees of severity and frequency of symptoms.

Symptoms of Dumping Syndrome

The symptoms of dumping syndrome can be quite diverse and may include both gastrointestinal issues as well as vasomotor symptoms. Most of these are mild, transient and can be easily managed with dietary modifications

Early dumping syndrome symptoms:

• Nausea and vomiting
• Abdominal pain and cramping
• Diarrhoea
• Bloating
• Dizziness
• Rapid heartbeat
• Sweating
• Flushing

Late dumping syndrome symptoms:

• Weakness
• Confusion
• Hunger
• Shakiness
• Rapid heartbeat
• Sweating
• Fainting (in severe cases)

Changes in Stomach Function Post-Surgery is the main cause behind dumping syndrome

After a sleeve gastrectomy, the stomach is reduced in size to approximately 150 mL, which allows food to pass into the intestines more quickly even if the pylorus valve, which helps control the flow of food, is still there. This rapid emptying may cause dumping syndrome symptoms.

In gastric bypass, the size of the stomach pouch is reduced to 50-80 mls which is then connected directly to the small intestine.

Comparing Dumping Syndrome: Gastric Sleeve vs. Gastric Bypass Surgery

While both gastric bypass and gastric sleeve surgeries are effective weight loss procedures, they differ in their approach and potential side effects.
