Gastritis

Introduction:

Gastritis is an inflammation of the stomach lining due to either erosion or atrophy.
Erosive causes include stresses such as physical illness or medications such as
nonsteroidal anti-inflammatory drugs (NSAIDs). Atrophic causes include a his-
tory of prior surgery (such as gastrectomy), pernicious anemia, alcohol use, or
Helicobacter pylori infection.

PROGNOSIS
Gastritis may cause changes within the cells of the stomach lining leading to mal-
nutrition, lymphoma, or gastric cancer. Hospitalized patients, especially in criti-
cal care settings, should have preventive medications to avoid the development
of gastritis.
