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