Gastritis
From Wikipedia, the free encyclopedia
| ICD-10 | K29.0-K29.7 |
|---|---|
| ICD-9 | 535.0-535.5 |
Gastritis is inflammation of the gastric mucosa. The word comes from the Greek gastro- meaning of the stomach and -itis meaning inflammation. Depending on the cause, it may persist acutely or chronically and may coincide with more serious conditions such as atrophy of the stomach.

The following are known causes of gastritis:
- Bacterial infection (most often by Helicobacter pylori and other Helicobacter bacteria)
- Fungal infection (most often in people with AIDS)
- Parasitic infection (most often from poorly cooked seafood)
- Viral infection
- Bile reflux
- NSAIDs
- Cigarette smoke
- Autoimmune disorders
- Excessive alcohol consumption
- Certain allergens
- Certain types of radiation
The following symptoms can be a result of gastritis or can be related to the underlying cause:
- Upper abdominal pain or discomfort
- Gastric hemorrhage
- Appetite loss
- Belching
- Nausea
- Vomiting
- Fever
- Fatigue
A doctor may order a barium meal test which are in some cases reliable in determining gastritis. However, the most reliable method for determining gastritis is a biopsy check during gastroscopy. For Helicobacter infection (the most common cause), one can test using a blood antibody test, stool antigen test, or a urea breath test.
Treatment usually consists of removing the irritant or the infection. In the case of Helicobacter infection, a doctor may prescribe antibiotics.
