Gastritis

Gastritis is the inflammation, irritation, or erosion of the protective mucosal lining of the stomach. It is broadly categorized into acute gastritis, characterized by sudden, severe mucosal inflammation, and chronic gastritis, which involves long-term, low-grade inflammatory changes that can lead to mucosal atrophy and epithelial metaplasia.

Infectious: Helicobacter pylori* infection is the most common cause globally.

• Pharmacological: Prolonged use of Nonsteroidal Anti-inflammatory Drugs (NSAIDs), aspirin, and corticosteroids.


• Toxic/Chemical: Excessive alcohol consumption, chronic bile reflux, and cocaine use.


• Physiological Stress: Severe burns (Curling's ulcers), central nervous system trauma (Cushing's ulcers), sepsis, or major surgery.


• Autoimmune: Autoimmune metaplastic atrophic gastritis, where antibodies attack gastric parietal cells and intrinsic factor.

The stomach lining is protected by a mucus-bicarbonate barrier that resists degradation by gastric acid and pepsin. Gastritis develops when noxious agents disrupt this barrier or when acid secretion overwhelms mucosal defenses.

• NSAID-induced: NSAIDs inhibit cyclooxygenase-1 (COX-1) enzymes, reducing prostaglandin synthesis, which decreases mucus and bicarbonate production and impairs mucosal blood flow.


• H. pylori-induced: The bacteria produce urease, neutralizing stomach acid to survive. They release cytotoxins (e.g., CagA, VacA) that recruit inflammatory cells, causing chronic mucosal damage.


• Autoimmune: T-cell mediated destruction of parietal cells leads to achlorhydria and loss of intrinsic factor, causing vitamin B12 deficiency (pernicious anemia).

Gastritis is a highly prevalent condition worldwide. H. pylori colonizes approximately 50% of the global population, with higher rates in developing countries. Chronic gastritis prevalence increases with age. Autoimmune gastritis is rarer, showing a female-to-male ratio of 3:1, typically presenting in individuals over 60 years old.

• Chronic NSAID or aspirin use

• Advanced age (>65 years)
• Heavy alcohol consumption and tobacco use
• History of autoimmune disorders (Type 1 diabetes, Hashimoto's thyroiditis)
• Severe physical stress (intensive care unit hospitalization)

• Vital Signs: Typically normal; tachycardia and hypotension may be present in cases of acute upper gastrointestinal bleeding.
• Inspection: Abdomen is usually non-distended unless severe bloating is present.
• Palpation: Mild to moderate tenderness localized to the epigastric region without guarding, rigidity, or rebound tenderness.
• Auscultation: Normal or hyperactive bowel sounds.

Esophagogastroduodenoscopy (EGD / Upper Endoscopy): Purpose: Direct visualization of the esophageal, gastric, and duodenal mucosa; allows for targeted biopsies. Typical Findings: Erythema, mucosal friability, subepithelial hemorrhages, erosions, or loss of rugal folds. Clinical Importance: The gold standard diagnostic modality for identifying and typing gastritis.

• Peptic Ulcer Disease (PUD): Differentiated by deep focal mucosal defects extending through the muscularis mucosae on endoscopy.
• GERD: Characterized by retrosternal burning pain (heartburn) and acid regurgitation, whereas gastritis pain is primarily epigastric and gnawing.
• Cholecystitis: Presents with right upper quadrant pain radiating to the right scapula, positive Murphy's sign, and abnormal biliary ultrasound.

• Peptic ulcer disease
• Gastric outlet obstruction (secondary to edema or scarring)
• Pernicious anemia (vitamin B12 deficiency)

Acute gastritis typically carries an excellent prognosis, resolving rapidly once the causative agent is eliminated. The prognosis for chronic gastritis is generally good but depends on the etiology; eradication of H. pylori cures the condition in most patients, whereas autoimmune atrophic gastritis requires lifelong monitoring due to irreversible mucosal changes.

• Rational, minimized use of NSAIDs.

• Moderate alcohol consumption.
