Gastritis

Definition:
Gastritis is an inflammation of the lining of the stomach.

Causes, incidence, and risk factors:

Gastritis can be caused by bacterial or viral infection, autoimmune disorders, or backflow of bile into the stomach (bile reflux).

Gastritis can also be caused by irritation from:

  • Medications (such as aspirin or anti-inflammatory drugs)
  • Alcohol
  • Chronic vomiting
  • Excess gastric acid secretion (such as from stress)
  • Eating or drinking caustic or corrosive substances (such as poisons)

Gastritis can occur suddenly (acute gastritis) or gradually (chronic gastritis).
