Dumping Syndrome

Overview

• Definition: A condition where undigested food moves too quickly from the stomach to the small intestine.
• Also Known As: Rapid gastric emptying.
• Common Occurrence: Following gastric and esophageal surgeries.
• Cause: Damage or removal of the pyloric sphincter, the valve separating the stomach and small intestine.

Types of Dumping Syndrome

Early Dumping

• Timing: 10 to 30 minutes after a meal.
• Mechanism: Rapid dumping of undigested food triggers fluid movement from bloodstream to intestine.
• Symptoms:
  • Bloating
  • Abdominal cramps
  • Nausea
  • Vomiting
  • Diarrhea
  • Reduced blood volume leading to rapid heart rates, dizziness, lightheadedness, or fainting.

Late Dumping

• Timing: 1 to 3 hours after eating.
• Mechanism: Rapid sugar absorption triggers excessive insulin production, causing hypoglycemia.
• Symptoms:
  • Weakness
  • Sweating
  • Confusion
  • Tremors

Dietary Management

• Goal: Manage symptoms through diet modifications.
• Dietary Recommendations:
  • Smaller, frequent meals.
  • Avoid high simple-sugar content foods.
  • Choose protein, fiber, and complex carbohydrate-rich foods.
  • Delay liquid intake until 30 minutes after meals.
  • Use thickening agents to increase food consistency.

Other Treatment Options

• Medications: To slow gastric emptying or inhibit insulin release.
• Surgical Interventions:
  • Tube feeding to bypass upper digestive tract.
  • Corrective surgery (e.g., pyloric sphincter reconstruction) as a last resort.
