Last Updated: July 3, 2026

Key Points

  • Stomach lining becomes irritated or inflamed
  • Common symptoms include tummy pain and indigestion
  • Caused by infection, certain painkillers, or alcohol
  • Untreated gastritis can lead to stomach ulcers

Overview

Gastritis refers to the inflammation of the stomach's inner lining. This condition can lead to discomfort, including pain, indigestion, and feelings of sickness. The most common causes include infection with H. pylori bacteria, regular use of anti-inflammatory painkillers like ibuprofen, excessive alcohol consumption, or severe stress. In some cases, it can also be due to an immune system issue where the body attacks its own stomach lining. Treatment for gastritis depends on its underlying cause. It often involves medications to reduce stomach acid, antibiotics for bacterial infections, and significant lifestyle adjustments. Early diagnosis and management are crucial to prevent complications like stomach ulcers.
