What are effective treatments for gastric ulcers?

Gastric ulcers—breaks in the mucosal lining of the stomach—are most commonly caused by Helicobacter pylori infection or chronic use of nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or aspirin. Effective treatment requires a multifaceted approach tailored to the underlying etiology.

First-line therapy for H. pylori-associated gastric ulcers is a 10- to 14-day course of triple or quadruple eradication therapy. This typically includes a proton pump inhibitor (PPI)—such as omeprazole, esomeprazole, or pantoprazole—to suppress gastric acid secretion and promote mucosal healing, combined with two or three antibiotics (e.g., amoxicillin, clarithromycin, metronidazole, or tetracycline) to eliminate the bacterial infection. Confirmation of eradication via urea breath test, stool antigen test, or endoscopic biopsy is recommended at least four weeks after completing therapy.

For NSAID-induced ulcers, immediate discontinuation of the offending agent is essential when clinically feasible. Concurrent PPI therapy (usually for 8 weeks) is the cornerstone of healing and symptom relief. In patients who require ongoing NSAID therapy—for example, those with rheumatoid arthritis or cardiovascular disease—a COX-2–selective NSAID (e.g., celecoxib) plus a PPI may be considered to reduce ulcer recurrence risk.

Adjunctive measures include lifestyle modifications: avoiding tobacco use (which impairs mucosal blood flow and delays healing), limiting alcohol intake (as ethanol can irritate the gastric mucosa), and minimizing stress-related behaviors that may exacerbate symptoms—though psychological stress alone does not cause ulcers. Dietary adjustments are generally not evidence-based for ulcer healing, but patients should avoid foods that consistently provoke discomfort.

In cases of complications—including bleeding, perforation, or gastric outlet obstruction—urgent endoscopic evaluation and intervention are required. Surgical consultation may be necessary if endoscopic management fails or if malignancy is suspected (e.g., non-healing ulcers, especially in older adults, warrant biopsy to exclude gastric adenocarcinoma).

Follow-up endoscopy is recommended for all gastric ulcers diagnosed endoscopically, particularly those larger than 2 cm or with atypical features, to confirm complete healing and rule out malignancy. Long-term PPI maintenance therapy may be indicated in select high-risk patients, such as those with recurrent ulcers or continued NSAID exposure, but should be used judiciously given potential risks associated with prolonged acid suppression.
