How is chronic superficial antral gastritis treated?

Chronic superficial antral gastritis refers to long-standing, mild inflammation confined to the mucosal layer of the gastric antrum—the lower portion of the stomach near the pylorus. It is commonly associated with Helicobacter pylori infection, but may also result from prolonged use of nonsteroidal anti-inflammatory drugs (NSAIDs), excessive alcohol intake, bile reflux, or autoimmune mechanisms. Diagnosis typically requires upper gastrointestinal endoscopy with targeted biopsies and histopathological evaluation.

Treatment is tailored to the underlying cause and symptom burden. First-line management for H. pylori-positive cases involves a 10- to 14-day eradication regimen—typically a proton pump inhibitor (PPI) combined with two antibiotics (e.g., amoxicillin and clarithromycin, or metronidazole and tetracycline in regions with high clarithromycin resistance) and sometimes bismuth subsalicylate. Confirmation of eradication via stool antigen testing or urea breath test is recommended at least four weeks after therapy completion.

For H. pylori-negative patients or those with persistent symptoms despite eradication, acid suppression with a PPI (e.g., omeprazole, esomeprazole, or pantoprazole) is often used empirically for 4–8 weeks. In cases linked to NSAID use, discontinuation or substitution with a COX-2 selective inhibitor—alongside gastroprotection—is advised. Lifestyle modifications, including avoidance of tobacco, alcohol, spicy foods, and caffeine, as well as stress reduction and regular meal timing, support mucosal healing and symptom control.

Importantly, chronic superficial antral gastritis is generally benign and rarely progresses to atrophy or intestinal metaplasia—unlike chronic atrophic gastritis. However, ongoing surveillance is not routinely indicated unless there are alarm features (e.g., unexplained weight loss, gastrointestinal bleeding, dysphagia, or anemia) or histologic evidence of premalignant changes on biopsy. Patients should be reassured that with appropriate management, most experience full symptomatic resolution and excellent long-term prognosis.
