Treatment of Gastritis
The treatment of gastritis depends on the underlying cause, symptom severity, and whether the condition is acute or chronic. Most people with gastritis respond well to a combination of medications, lifestyle changes, and—in the case of bacterial infection—antibiotic therapy.
Medications
1. Proton Pump Inhibitors (PPIs)
Reduce stomach acid production and promote healing of the lining
Common examples include omeprazole, lansoprazole, and pantoprazole
Usually taken for 4–8 weeks, depending on severity
2. H2-Receptor Blockers
Alternative to PPIs, with similar effect but slightly milder
Examples: ranitidine (withdrawn in many countries), famotidine
3. Antacids
Provide short-term relief by neutralising existing stomach acid
Useful for mild, infrequent symptoms
4. Antibiotics
Used to eradicate H. pylori if present
Common regimen includes a combination of two antibiotics (e.g. clarithromycin and amoxicillin) plus a PPI
Full course must be completed to prevent resistance
Treatment of Autoimmune Gastritis
Requires vitamin B12 injections to correct deficiency
Ongoing monitoring for anaemia and stomach cancer risk is essential
Immunosuppressants may be used in rare severe cases
Lifestyle and Dietary Modifications
Avoid spicy, acidic, and greasy foods that trigger symptoms
Limit caffeine, alcohol, and smoking
Eat smaller, more frequent meals
Avoid eating late at night or lying down immediately after meals
Manage stress through exercise, relaxation techniques, or counselling
Natural and Supportive Therapies
Probiotics may help balance gut bacteria, particularly after antibiotic use
Treatment of Gastritis
Herbal remedies such as liquorice root or chamomile tea may offer mild soothing effects—though medical advice should be sought before use
Most patients with gastritis experience relief within a few weeks of starting treatment. Persistent or recurrent cases may require further investigation or long-term acid suppression therapy.
