==Overview==
==[[Gastritis causes|Causes]]==
'''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.


==Common Causes of Gastritis==
==[[Gastritis differential diagnosis|Differentiating Gastritis from other Diseases]]==
The following are known causes and factors related to gastritis:


[[Image:DigestiveSystem.gif|frame|left|Digestive System]]
==[[Gastritis epidemiology and demographics|Epidemiology and Demographics]]==


* [[Bacterial]] [[infection]] (most often by ''[[Helicobacter pylori]]'' and other ''[[Helicobacter]]'' spp.)
==[[Gastritis risk factors|Risk Factors]]==
* [[Fungal]] infection (most often in people with [[immunodeficiency]])
* [[Parasitic]] infection (most often by ''[[Anisakis]]'' spp. from poorly cooked seafood)
* [[Virus|Viral]] infection
* [[Bile]] reflux
* [[NSAIDs]]
* [[Cigarette]] smoke
* [[Autoimmune]] disorders
* Excessive [[alcohol]] consumption
* Excessive [[caffeine]] consumption
* Certain [[allergen]]s
* Certain types of [[radiation]]
* Stomach injury
* [[stress (medicine)|Stress]]


== Differential Diagnosis ==
==[[Gastritis screening|Screening]]==
* [[Alcoholic]] gastropathy
* [[Aortic aneurysm]] (ruptured)
* [[Bacterial infection]]s
* [[Burns]]
* [[Candida]]
* Corrosive gastritis
* [[Crohn's Disease]]
* [[Cytomegalovirus]] (CMV) in [[HIV]]
* Diseases of the biliary system
* [[Drugs]]
* [[Eosinophilic Gastritis]]
* [[Esophageal varices]]
* Functional dyspepsia
* [[Gastric carcinoma]]
* Gastritis in [[pernicious anemia]]
* [[Gastroduodenal ulcer]]
* [[Helicobacter pylori]] associated
* Intoxication
* [[Liver failure]]
* Lymphocytic gastritis
* [[Mallory-Weiss Tear]]
* [[Menetrier's Disease]]
* [[Pancreas carcinoma]]
* [[Pancreatitis]]
* [[Peptic ulcer]]
* [[Perforated ulcer]]
* [[Radiation]]
* Reflux esophagitis
* [[Renal Failure]]
* Respiratory failure
* [[Sarcoidosis]]
* [[Sepsis]]
* [[Shock]]
* [[Surgery]]
* [[Syphilis]]
* [[Trauma]]
* [[Tuberculosis]]
* [[Volvulus]]
* [[Zollinger-Ellison Syndrome]]


== Symptoms ==
==[[Gastritis natural history, complications and prognosis|Natural History, Complications and Prognosis]]==
The following symptoms can be a result of gastritis or can be related to the underlying cause:


* Upper [[abdominal pain]] or discomfort
==Diagnosis==
* Gastric [[hemorrhage]]
[[Gastritis history and symptoms| History and Symptoms]] | [[Gastritis physical examination | Physical Examination]] | [[Gastritis laboratory findings|Laboratory Findings]] | [[Gastritis x ray|X Ray]] | [[Gastritis CT|CT]] | [[Gastritis endoscopy|Endoscopy]] | [[Gastritis other imaging findings|Other Imaging Findings]] | [[Gastritis other diagnostic studies|Other Diagnostic Studies]]
* [[Hypochlorhydria]]
* [[Appetite]] loss
* [[Belching]]
* [[Nausea]]
* [[Vomiting]]
* [[Fever]]
* [[Lethargy]]


== Diagnosis ==
==Treatment==
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==
==Case Studies==
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.
