Can Low Stomach Acid Cause GERD?

Yes, low stomach acid (hypochlorhydria) can contribute to gastroesophageal reflux disease (GERD). While GERD is typically associated with excess stomach acid, low stomach acid can also be a factor. Here’s how low stomach acid can lead to GERD:
- Inadequate Digestion: Stomach acid is essential for breaking down food, especially proteins. Low stomach acid can lead to poor digestion, resulting in undigested food particles. These particles can cause bloating and increased pressure in the stomach, which can push stomach contents, including acid, back up into the esophagus.
- Bacterial Overgrowth: Low stomach acid can lead to bacterial overgrowth in the stomach and small intestine. This can cause fermentation of carbohydrates, leading to gas production, increased intra-abdominal pressure, and reflux.
- Lower Esophageal Sphincter Function: Stomach acid helps to signal the lower esophageal sphincter (LES) to close properly after food enters the stomach. With low stomach acid, the LES may not function correctly, allowing stomach contents to reflux into the esophagus.
- Imbalance of Digestive Enzymes: Low stomach acid can affect the production of digestive enzymes from the pancreas and bile from the gallbladder, further impairing digestion and leading to symptoms that mimic or exacerbate GERD.
Addressing low stomach acid often involves dietary changes, lifestyle modifications, and possibly supplementation with hydrochloric acid (HCl) or digestive enzymes under the guidance of a healthcare professional. If you suspect low stomach acid is contributing to your GERD symptoms, it is best to consult with a healthcare provider for proper diagnosis and treatment.
