About this condition
Gastritis means inflammation of the stomach lining; gastroduodenitis also involves the beginning of the small intestine. Helicobacter pylori infection, certain medicines and other factors can contribute. Burning or pain in the upper abdomen is not proof of inflammation.
How the symptom or condition presents
Some chronic changes cause few or no symptoms. When discomfort is present it may resemble functional dyspepsia, including early satiety, nausea and post-meal fullness. Understanding the cause may require previous biopsy or endoscopy findings and the overall history.
Important differences and warning signs
Do not equate every stomach complaint with gastritis or assume all gastritis is treated the same way. H. pylori should be diagnosed using appropriate validated tests when indicated; a random antibiotic regimen without evidence of infection is not advised. Ulcer disease and functional disorders need separate consideration.
Evaluation and individual care
Bring past endoscopy, histology and H. pylori results, and list painkillers such as ibuprofen, aspirin and other regular medicines. Treatment may target a confirmed infection or medication-related injury. Long-term acid suppression should be reviewed rather than continued indefinitely without reassessment.

Signs and symptoms
- Upper abdominal discomfort or burning, with or without meals.
- Nausea, belching, early satiety or post-meal heaviness.
- Some people have no noticeable symptoms at all.
Diagnosis and tests
Assessment includes symptom history, medicine exposure, possible H. pylori infection and alarm features. When justified, appropriate testing, gastroscopy or biopsy helps clarify the diagnosis; symptoms alone cannot confirm mucosal inflammation.
Care and treatment approaches
Confirmed H. pylori infection may need a clinician-selected eradication regimen and a test of cure at an appropriate interval. Medication-related injury and other causes require different management; avoid self-prescribing antibiotics or indefinite acid suppression.
When to seek urgent care
Call 103 or 112 for vomiting blood, black tarry stools, fainting or sudden severe or escalating abdominal pain. These warning signs are not routine features of uncomplicated dyspepsia.
Frequently asked questions
Does every episode of stomach pain mean gastritis?
No. Similar discomfort can occur with functional dyspepsia, ulcers or non-gastric conditions. The diagnosis must follow evaluation.
Should I take antibiotics against H. pylori without a test?
No. Treatment should follow confirmation where indicated and a clinician-selected regimen, with appropriate follow-up testing.
Do all people with gastritis need the same diet?
No. Dietary triggers and underlying causes differ. Individual recommendations are preferable to a long list of universal prohibitions.
