The diagnosis criteria of gastroparesis syndrome include clinical manifestations, endoscopic examination, gastric emptying examination results, etc.

1. Clinical manifestations

If the patient has nausea, vomiting, early satiety, postprandial satiety, abdominal pain and other symptoms after eating, it is considered to be related to gastroparesis syndrome.

2. Endoscopic examination

If the patient has no obvious abnormalities after gastroscopy, it should also be highly suspected to be related to gastroparesis syndrome.
