What should I do if I experience heartburn one hour after eating?

Heartburn occurring one hour after eating requires treatment based on the underlying cause. Common contributing factors include dyspepsia, gastroesophageal reflux disease (GERD), and chronic erosive gastritis.

1. Dyspepsia

If improper dietary habits lead to dyspepsia, gastric motility typically slows down, prolonging gastric emptying time and causing food to remain in the stomach for an extended period—resulting in heartburn approximately one hour after a meal. In such cases, patients may take acid-suppressing medications as prescribed by their physician; commonly used agents include famotidine and ranitidine.

2. Gastroesophageal Reflux Disease (GERD)

When gastric chyme, gastric acid, pepsin, and duodenal bile reflux into the esophagus, they can cause physical damage to the esophageal mucosa, manifesting as heartburn and acid regurgitation. Mucosal protective agents, prescribed per medical guidance, can help alleviate symptoms; commonly used medications include colloidal bismuth pectin and sucralfate.

3. Chronic Erosive Gastritis

In patients with chronic erosive gastritis, excessive gastric acid secretion often irritates the gastric mucosa, leading to heartburn approximately one hour after eating. Under physician supervision, patients may be prescribed proton pump inhibitors (PPIs) such as rabeprazole or omeprazole for treatment.
