Gastritis is inflammation of the gastric mucosa of the stomach. Depending on the cause, gastritis may persist acutely or chronically and may coincide with more serious conditions such as atrophy of the stomach.
Causes
The following are known causes and factors related to gastritis:
- Bacterial infection (most often by Helicobacter pylori and other Helicobacter spp.)
- Fungal infection (most often in people with immunodeficiency)
- Parasitic infection (most often by Anisakis spp. from poorly cooked seafood)
- Bile reflux
- NSAIDs
- Cigarette smoke
- Autoimmune disorders
- Excessive alcohol consumption
- Excessive caffeine consumption
- Certain allergens
- Certain types of radiation
- Steroid treatments for other conditions
- Stomach injury
- Stress
The following symptoms can be a result of gastritis or can be related to the underlying cause:
- Upper abdominal pain or discomfort
- Gastric hemorrhage
- Hypochlorhydria
- Appetite loss
- Belching
- Nausea
- Vomiting
- Fever
- Lethargy
Diagnosis
In suspected cases, a doctor usually orders a barium meal test and gastroscopy to determine gastritis and related conditions such as peptic ulcers and gastric cancer. It is always important that the doctor reviews a patient's history regarding medications, alcohol intake, smoking, and other factors that can be associated with gastritis. In some cases, the appearance of the stomach lining seen during gastroscopy and the results of the barium meal test are reliable in determining gastritis and the cause. However, the most reliable method for determining gastritis is doing a biopsy during gastroscopy and checking for histological characteristics of gastritis and infection. For Helicobacter infection (the most common cause), one can test non-invasively with a ure breath test, stool antigen test, or blood antibody test.
If diarrhea is present also, the correct diagnosis may be not gastritis but rather gastroenteritis.
Treatment
Treatment for gastritis usually consists of removing the irritant or the infection. In cases of infection, a doctor will most often prescribe antimicrobial drugs. Helicobacter infection typically responds well to the triple therapy protocol (consisting of two antibiotics, and a proton pump inhibitor). Regimens that work well include PCA or PCM triple therapy (PPI, Clarithromycin, Amoxicillin) or (PPI, Clarithromycin, Metronidazole). Quadruple therapy has a >90% success rate and includes PPIs, Bismuth subsalicylates, Metronidazole, and Tetracycline.
