QuestionHello doctor, can I ask why I've been back from a gastroscopy for more than a day but my mouth is always bitter?

Hello, usually before gastroscopy, the doctor will spray anesthetic into the oropharynx to reduce irritation when the bronchoscope is inserted. Usually, 1 hour after the anesthetic is injected, sensation will return to the pharynx. In your case, it may be because you are quite sensitive to the anesthetic or because the amount of local anesthetic spray is too much, so you still have a bitter taste in your mouth. If the next day or two you still have a bitter taste in your mouth, you should see an otolaryngologist. And you are sure that before the endoscopy you did not have a bitter taste in your mouth.
