You can eat the night before the gastroscopy, but it is recommended to eat some liquid or semi-liquid food.
When patients undergo gastroscopy, they need to ensure that the digestive system is clean and free of debris, and to ensure that the gastric mucosa is adequately visualized, so dietary control is usually carried out before gastroscopy. The day before the gastroscopy, it is recommended to eat well-digested food during the day to ensure the supply of energy, but also to promote the digestion and absorption of food, and reduce food residue.
In the evening, you can also eat, but it is recommended to eat earlier, eat some especially well-digested fluids, semi-fluids, food with less food residue, to avoid large amounts of food, resulting in food residue, obscuring the field of view of the gastroscope, affecting the results of gastroscopy.
