It is not possible to eat immediately after painless gastroscopy, it is generally recommended to eat in 2~4 hours, but to do painless gastroscopy at the same time for surgical treatment or taking tissue biopsy, it is necessary to prohibit food and water, and in most cases you can consider eating after 24 hours.
Painless gastroscopy is based on normal gastroscopy using certain anesthetic agents to put the patient to sleep and complete the gastroscopy without self-consciousness.
If the painless gastroscopy is simply performed, the patient can usually eat appropriately after he/she is conscious after the examination, which takes about 2~4 hours.
If a surgery or tissue biopsy is performed at the same time as the painless gastroscopy, the time for eating needs to be extended, and in most cases, eating can be done after 24 hours.
Eating after gastroscopy should be based on light, easy-to-digest foods, and the specific diet should follow the doctor’s instructions.
