Improve Gut Health Editorial Team • Feb 20, 2026 • 7 min read

Approach to reflux that looks beyond acid suppression to gut health drivers.

Quick answer

Reflux often reflects multi-factor drivers: stomach acid, esophageal function, gastric emptying, and gut microenvironment. Testing should be guided by symptoms and clinician input.

Testing pathways

  • H. pylori testing if symptoms suggest ulcer disease.
  • Gastric emptying studies if meals worsen symptoms.
  • Breath testing for SIBO and bile acid malabsorption as indicated.
  • Assessment of diet, weight, and sleep as contributors.
