| ==Overview==
| |
| '''Gastritis''' is [[inflammation]] of the [[gastric mucosa]]. The word comes from the [[Greek language|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.

| == Diagnosis ==
| |
| | |
| In suspected cases, a doctor usually orders a [[barium meal]] test and [[gastroscopy]] to determine gastritis and related conditions such as [[peptic ulcer]]s 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 [[histology|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]] [[stool test|test]], or [[blood]] [[antibody]] test.

| 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 [[antibiotic]]s, and a [[proton pump inhibitor]]). Regimens that work well include PCA or PCM triple therapy ([[PPI]], Clarithromycin, Amoxicillin) or (PPI, Clarithromycin, Metronidazole). Quadruple therapy hasa >90% success rate and includes PPIs, Bismuth subsalicylates, Metronidazole, and Tetracycline.
