Gastritis:  inflammation of the stomach.  This inflammatory disorder of the gastric mucosa may be acute or chronic.  Acute gastritis is the most common stomach disorder.  In a patient with epigastric discomfort or other GI symptoms (particularly bleeding), a history suggesting exposure to a GI irritant suggests gastritis.  Gastritis usually accompanies pernicious anemia (as chronic atrophic gastritis).  Gastritis is more prevalent in the elderly, but can occur at any age.

Cause:  Acute gastritis may be caused by:
Chronic ingestion of irritating foods or an allergic reaction to them.
Alcohol or drugs, such as aspirin
Poisons, such as: DDT, ammonia, mercury, and carbon tetrachloride
Hepatic disorders, such as: portal hypertension
Gi disorders, such as: spure
Infectious disorders
Curling's ulcer (after a burn)
Cushing's ulcer
Gi injury may be thermal such as:  ingesting a hot fluid, or mechanical - such as: swallowing a foreign object.

Corrosive gastritis may be caused by ingestion of strong acids or alkalies.

Acute phlegmonous gastritis may be caused by a rare bacterial infection of the stomach wall (usually streptococcal)


GI bleeding
Mild epigastric discomfort


Symptoms are usually relieved by eliminating the gastric irritant or other cause.

Corrosive gastritis:  to neutralize with the appropriate antidote (emetics are contraindicated).

Gastritis cause by poisons:  emetics, anticholinergics such as methantheline bromide

GI distress:  histamine anatagonists such as cimetidine, and antacids

When gastritis causes massive bleeding, treatment includes blood replacement; iced saline lavage, possibly with norepinephrine; angiography with vasopressin infused in normal saline solution; and surgery.

Bacterial gastritis:  antibiotic therapy, bland diet, and antiemetic.

Acute phlegnonous gastritis:  Vigorous antibiotic therapy followed by surgical repair.

NOTE:  with all medication use as directed by your doctor.
