10 Low Stomach Acid Symptoms
Reviewed: Dr. Gromatzky
Symptom #2: Belching
Belching one hour after meals is a common symptom of low stomach acid. Gastric acid triggers opening of the pyloric valve that leads to the duodenum and the small intestines. This happens once hydrochloric acid has broken down food in the stomach and changed it into an acidic mass of nutrients.
The increased acidity triggers the pyloric valve to open to let out the digested food into the duodenum for absorption of nutrients through the walls of the small intestines. In the absence of sufficient gastric acid, the food in the stomach does not become adequately acidic to trigger opening of the pyloric valve. Instead, the food starts fermenting. This produces chemicals and gases that flow back into the esophagus and cause belching.
