Gastritis
Epidemiology

Caused by drugs, chemicals, or Helicobacter pylori infection
-
-
Pathophysiology
Acute gastritis
-
H.pylori causes inflammation, increased gastric secretion in antral gastritis, decreased gastric section in fundal gastritis
Chronic gastritis
The gastric mucosa degenerates extensively in the body and the fundus of the stomach, leading to gastric atrophy. The feedback mechanism that normally inhibits gastrin secretion is impaired.
Treatment
Acute gastritis
-
Discontinue injurious drugs, using antacids, or decreasing acid secretion with H2 receptor anatagonists
Chronic gastritis
Symptom management
Eating smaller meals with soft, bland diet
