It is generally not recommended for patients to repeat gastroscopy within a short period of time, but patients may need to repeat gastroscopy if their situation is urgent. As gastroscopy is an invasive examination, it will cause some irritation to the mucous membrane of the digestive tract, and patients may also experience nausea, vomiting, foreign body sensation in the throat, hoarseness and other uncomfortable symptoms, and some patients may also experience blood in the stool. These uncomfortable symptoms need time to recover. If the second gastroscopy is continued within a short period of time, it may aggravate the damage to the body, due to the need for gastric polyps and biopsy of some patients, there will be a certain impact. Therefore, it is not recommended to repeat the gastroscopy within a short period of time, and it is recommended to have an interval of about 3 months, after the digestive mucosa has basically recovered. However, if the patient’s situation is urgent, for example, if it is a gastrointestinal hemorrhage, it is necessary to perform gastroscopy as well as gastroscopic treatment when it is needed, and it is also necessary to repeat the gastroscopy. Therefore, whether the patient needs to repeat gastroscopy still depends on the specific situation, and it is recommended to follow the doctor’s instructions.
