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.
