Gastroscopy is able to see the throat. Gastroscopy can directly observe the part being examined, when doing gastroscopy, it is necessary to pass through the pharynx and esophagus to enter the stomach, so in the process of gastroscopy, the examiner is able to see a part of the pharynx, but gastroscopy mainly observes lesions in the stomach and esophagus, and is not sufficiently comprehensive and detailed for the observation of lesions in the pharynx. If there is discomfort in the throat, it is not recommended that the patient perform a gastroscopy, and it is recommended that the patient go to the otorhinolaryngology department of the hospital for a laryngoscopy, etc., so that he or she can see the lesions in the throat more clearly, and under the guidance of the physician, he or she can carry out targeted treatment.
