Gastritis — inflammation of the stomach lining — affects millions of people around the world, often without them realizing it. Whether caused by H. pylori infection, stress, autoimmune reactions, or long-term use of medications like NSAIDs, gastritis can silently progress from mild irritation to serious complications like ulcers or even gastric cancer.
Understanding the science behind gastritis helps you take control of your digestive health — and prevent long-term damage.

Gastritis refers to inflammation, irritation, or erosion of the gastric mucosa — the protective lining of your stomach. It can appear suddenly (acute gastritis) or develop slowly over time (chronic gastritis).
