Gаstritis 1. Bаckgrоund Definitiоn: Inflаmmatiоn or injury of the gastric mucosa, which may be acute (short-term mucosal irritation) or chronic (persistent inflammation leading to mucosal atrophy or metaplasia). Pathophysiology: Acute gastritis: Direct mucosal injury from acid, NSAIDs, alcohol, bile reflux, or stress → mucosal edema, erosion, hemorrhage. Chronic gastritis: Persistent inflammation, often from H. pylori infection or autoimmune destruction of parietal cells (type A). Types: Type A (autoimmune) — body/fundus predominant; leads to B12 deficiency and pernicious anemia. Type B (H. pylori–related) — antral predominant; most common form worldwide. Epidemiology: Very common; risk increases with NSAID use, age, and H. pylori prevalence. 2. History Symptoms: Epigastric pain, nausea, vomiting, early satiety, bloating; may be asymptomatic. Alarm features: Hematemesis, melena, anemia, weight loss. Risk factors: NSAIDs, aspirin, alcohol, corticosteroids, stress (ICU/trauma), H. pylori infection, autoimmune disorders, smoking. Autoimmune gastritis clues: Fatigue, pallor, glossitis, or neuropathy (vitamin B12 deficiency). 3. Exam Findings Often normal or mild epigastric tenderness. Signs of anemia (pallor, tachycardia) if bleeding or B12 deficiency. In severe stress cases: hypotension or occult GI bleeding. 4. Making the Diagnosis Gold standard: Upper endoscopy (EGD) with biopsy — shows mucosal erythema, erosions, or atrophy and allows H. pylori testing. Commonly used alternatives: Urea breath test or stool antigen for H. pylori when endoscopy not indicated. CBC to evaluate for anemia; B12 level if autoimmune suspected. Indications for endoscopy: Alarm symptoms, persistent pain, or risk factors for malignancy. 5. Management A. Lifestyle / Supportive Stop offending agents (NSAIDs, alcohol). Small, frequent meals; avoid irritant foods and caffeine. B. Medication H. pylori–positive: Eradication therapy (PPI + clarithromycin + amoxicillin or bismuth quadruple regimen). NSAID-related: Discontinue NSAID; start PPI for 4–8 weeks. Stress gastritis (ICU): IV PPI or H2 blocker prophylaxis. Autoimmune: Treat B12 deficiency; monitor for gastric carcinoma or carcinoid risk. C. Complications Peptic ulcer formation, upper GI bleeding, iron or B12 deficiency, increased risk of gastric adenocarcinoma (chronic forms). Question A 58-year-old woman presents with fatigue and mild epigastric discomfort. She denies NSAID or alcohol use. Physical examination reveals a smooth, red tongue and decreased vibratory sensation in the lower extremities. Laboratory testing shows hemoglobin of 10.2 g/dL and mean corpuscular volume of 110 fL.
