You are not allowed to eat 1 hour after gastroscopic polyp removal and usually need to fast for at least 8 hours – 12 hours.
In this case after gastroscopic polypectomy, the time to eat needs to be determined by the size and number of polyps as well as the size of the surgical wound; the more severe the trauma, the longer the time needed to fast. Usually at least 8-12 hours of fasting is required. Eating too soon can irritate the wound in the gastric mucosa, leading to mucosal bleeding and stomach pain.
After 8-12 hours, patients can properly eat some liquid food, such as soups and porridges, and try not to eat raw and hard food. As the mucosal wound recovers, normal diet can be resumed gradually, but it should also be based on soft and non-stimulating food, do not eat raw and cold as well as spicy and stimulating food, otherwise it will increase the burden on the stomach and intestines, and it will have an impact on the recovery of gastric mucosa.
If you experience stomach discomfort after gastroscopic polyp removal, it is recommended that you go to the hospital as soon as possible and get relevant treatment with the help of your doctor.
