It is better to eat some easy-to-digest food after gastroscopy. If no gastric mucosal abnormality is found during gastroscopy and no relevant treatment is needed, easy-to-digest food can be used on the same day, because gastroscopy may cause some gastric discomfort, and easy-to-digest food, such as gruel, can be eaten to avoid discomfort. When eating, you should pay attention to chewing and swallowing slowly, so as to facilitate the digestion of the stomach. And after the gastroscopy must not drink alcohol, drinking may cause gastrointestinal stimulation, and pay attention to observe their stool, if there is black stool, to the hospital in time for review. But it should be noted that generally ordinary gastroscopy 1 hour after eating, painless gastroscopy 2 hours before eating, prohibit eating spicy stimulating food.
