'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.
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)
★
Viral infection
★
Bile reflux
★
NSAIDs
★
Cigarette smoke
★
Autoimmune disorders
★ Excessive
alcohol consumption
★ Excessive
caffeine consumption
★ Certain
allergens
★ Certain types of
radiation
★ Stomach injury
★
Stress
Symptoms
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
urea breath test,
stool antigen test, or
blood antibody test.
Treatment
Treatment 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).
