Acute Gastritis Clinical Presentation
- Author: Mohammad Wehbi, MD; Chief Editor: Julian Katz, MD more...
History
- Gnawing or burning epigastric distress, occasionally accompanied by nausea and/or vomiting. The pain may improve or worsen with eating.
- Previous mucosal injury (eg, gastritis, peptic ulcer disease, endoscopic injury caused by polypectomy, injury caused by any surgery)
- History of eating raw fish
- Exposure to potentially noxious drugs or chemical agents. This includes corticosteroids or other prescription medications that can cause gastritis.
- Routine use of aspirin or NSAIDs, especially at high doses
Physical
The physical examination findings are often normal with occasional mild epigastric tenderness. The examination tends to exhibit more abnormalities as the patient develops complications in relation to gastritis.
Causes
Acute gastritis has a number of causes, including certain drugs; alcohol; bacterial, viral, and fungal infections; acute stress (shock); radiation; allergy and food poisoning; bile; ischemia; and direct trauma.
- Drugs - NSAIDs, such as aspirin, ibuprofen, and naproxen; cocaine; iron; colchicine, when at toxic levels, as in patients with failing renal or hepatic function; kayexalate; chemotherapeutic agents, such as mitomycin C, 5-fluoro-2-deoxyuridine, and floxuridine
- Potent alcoholic beverages, such as whisky, vodka, and gin
- Bacterial infections -H pylori (most frequent), H heilmanii (rare), streptococci (rare), staphylococci (rare), Proteus species (rare), Clostridium species (rare), E coli (rare), tuberculosis (rare), secondary syphilis (rare)
- Viral infections (eg, CMV)
- Fungal infections - Candidiasis, histoplasmosis, phycomycosis
- Parasitic infection (eg, anisakidosis)
- Acute stress (shock)
- Radiation
- Allergy and food poisoning
- Bile: The reflux of bile (an alkaline medium important for the activation of digestive enzymes in the small intestine) from the small intestine to the stomach can induce gastritis.
- Ischemia: This term is used to refer to damage induced by decreased blood supply to the stomach. This rare etiology is due to the rich blood supply to the stomach.
- Direct trauma
