Alcohol and gastritis: Why your stomach hurts after drinking

Published October 29, 2024 · 6 min read · Updated April 2026

Reviewed for accuracy by licensed clinical professionals.

Alcohol directly irritates and inflames the stomach lining, producing the burning, nausea, and pain that many heavy drinkers experience.

How it happens

Alcohol increases stomach acid production while weakening the protective mucus lining. This combination produces inflammation (gastritis) that ranges from mild discomfort to bleeding ulcers.

Symptoms

Burning stomach pain, especially after eating. Nausea and vomiting. Bloating. Loss of appetite. Vomiting blood (medical emergency).

Healing

Mild gastritis often resolves within days to weeks of abstinence. The stomach lining has remarkable regenerative capacity. Severe or chronic gastritis may require medication (proton pump inhibitors). Ulcers may take weeks to months to heal.
