Diagnosis is made by demonstrating delayed gastric emptying in a symptomatic patient after excluding other potential causes of the symptoms. The symptoms of gastroparesis are non-specific and can mimic other disorders, such as ulcer disease, partial gastric or small-bowel obstruction, gastric cancer, or pancreatobiliary disorders.Clinicians should also recognise that gastroparesis could be a presenting symptom of a generalised gastrointestinal motility disorder.
