Painless gastroscopy is performed on the basis of general anesthesia, the patient will be in a state of loss of consciousness to carry out gastroscopy, and after the end of the examination the patient’s state of consciousness needs a period of time to recover, the whole process needs to be accompanied by a family member or a friend, which will help to observe the changes in the condition in time, and notify the doctor in time once you find any uncomfortable symptoms. General gastroscopy generally does not need to be accompanied. It is also important to note that before the gastroscopy, you need to prepare your diet and ensure that you cannot eat for 8 hours. Patients who need a painless gastroscopy are advised to do so under the guidance of a doctor.
