GERD & Acid Reflux: Why Antacids Make It Worse and What Actually Works

The short answer

GERD & Acid Reflux: Why Antacids Make It Worse and What Actually Works

Most acid reflux is caused by too LITTLE stomach acid, not too much. Here's why antacids are making your GERD worse and what to do instead.

The Acid Reflux Paradox

Most GERD is caused by too little stomach acid, not too much. Low acid means food sits longer, ferments, creates gas, and pushes the sphincter open.

Root Causes of GERD

  • Hypochlorhydria — chronic stress, aging, H. pylori, zinc deficiency
  • H. pylori Infection — suppresses acid while causing inflammation
  • SIBO — fermentation increases abdominal pressure
  • Food Sensitivities — gluten, dairy, and other triggers
  • Hiatal Hernia — structural sphincter compromise

Our GERD Resolution Protocol

  1. H. pylori and SIBO testing
  2. Stomach acid assessment — too much or too little?
  3. Digestive enzyme and HCl support (when appropriate)
  4. Food sensitivity identification
  5. Gut healing — repair esophageal and stomach lining. See our leaky gut healing protocol
  6. Stress management — vagus nerve controls acid production
  7. Gradual PPI tapering (if applicable, under supervision)
