2. Examination precautions: Before the general gastroscopy, it is necessary to prohibit food and water for 4 hours, and try not to eat fried chicken and other indigestible food the day before the examination. After the examination, you can leave if there is no discomfort, and you can eat if there is no discomfort in your throat.
