Gastroscopy general anesthesia for 5-year-old children is very little harm to the body, occasionally children have adverse reactions, but if the child itself has no underlying disease, the incidence is very low.
The hazards of general anesthesia for gastroscopy include the adverse reactions of anesthetic drugs and the hazards caused by the gastroscope itself, the former including cardiac arrhythmia, mental disorders, transient hypoxia, allergies, etc., and the latter including reflux of gastric juices, severe vomiting, and edema of the vocal cords.

Currently under general anesthesia gastroscopy technology has been more mature, the incidence of adverse reactions is very low, parents do not need to worry too much.
