Gastritis

Gastritis Overview

Gastritis, an inflammation or irritation of the lining of the stomach, is not a single disease. Rather, gastritis is a condition that has many causes. Common to all people with gastritis is pain or discomfort in the upper part of the belly (abdomen), also called dyspepsia.

Gastritis can be a brief and sudden illness (acute gastritis), a longer-lasting condition (chronic gastritis), or a special condition, perhaps as part of another medical illness.

  • An example of acute gastritis is stomach upset that may follow the use of alcohol or certain medications such as aspirin or nonsteroidal anti-inflammatory drugs.
  • Helicobacter pylori is a type of bacteria that infects the stomach. Infection with this bacteria may lead to chronic gastritis.

Gastritis is a common medical problem, with up to10% of people who come to a hospital emergency department with the complaint of abdominal pain being ultimately diagnosed with gastritis.
