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).

Symptoms

     
  • hiccups  
  • abdominal indigestion  
  • loss of appetite

  • dark stools

Signs and tests
Tests vary depending on the specific cause. An upper GI X-ray, EGD, or other tests may be advised.

Treatment
Treatment depends on the specific cause. Some of the causes will resolve over time. Medications to decrease stomach acid secretion may be recommended.

Expectations (prognosis)
The outlook depends on the cause, but is usually good.

Complications
