Gastritis is defined as histological evidence of inflammation of the gastric mucosa. The broader term gastropathy encompasses lesions characterised by minimal or no inflammation.[1][2][3]

Patients may present with generalised dyspepsia or epigastric discomfort. However, these features are often non-specific.[3][30]Diagnosis is based upon clinical and relevant medical history and exclusion of benign and malignant gastrointestinal ulcerations as the cause of the symptoms.[30] Clinical guidelines have been established to aid the evaluation of patients with dyspepsia, and these should be applied to patients with suspected gastritis.[30][31] A histological diagnosis of gastritis is commonly made in patients without gastrointestinal symptoms.
