Overview

Gastritis is inflammation of the gastric mucosa. The word comes from the Greek gastro- meaning of the stomach and -itis meaning inflammation. Depending on the cause, it may persist acutely or chronically and may coincide with more serious conditions such as atrophy of the stomach.

Historical Perspective

In 1728, a German physician named Georg Ernst Stahl first used the term "gastritis" to describe inflammation of the inner lining of the stomach.

Classification

Gastritis may be classified according to chronicity, into two categories: acute and chronic.

Pathophysiology

Causes

The most common causes of Gastritis include H. pylori infection, alcohol consumption, cigarette smoking, extended use of NSAIDs and autoimmune gastritis. Less common causes of Gastritis include cocaine addiction, bile reflux, and Crohn's disease.

Differentiating Gastritis overview from Other Diseases

Gastritis must be differentiated from peptic ulcer disease, gastric cancer, gastroesophageal reflux disease, gastroenteritis, and Crohn's disease.

Epidemiology and Demographics

Risk Factors

Common risk factors in the development of Gastritis include alcohol, NSAIDs, cocaine, autoimmune gastritis, Crohn’s disease, HIV/AIDS and bacterial infections such as Helicobacter pylori.
