After a painless gastroenteroscopy, you can usually prepare for pregnancy normally on the 2nd day. If there are abnormalities in the liver or kidney function, the preparation time needs to be extended. During painless gastroenteroscopy, general anesthesia is usually administered intravenously. However, for normal people, the anesthesia used during painless gastroenteroscopy can be metabolized quickly and completely, and usually does not have a greater impact on pregnancy. For safety reasons, if there is no obvious abnormality in the gastroenteroscopy examination, you can prepare for pregnancy normally after the painless gastroenteroscopy procedure with the first menstrual period. However, if there are abnormalities in liver or kidney function, you can actively find out the cause of the abnormalities in liver and kidney function after the painless gastroenteroscopy, actively treat them, and then prepare for pregnancy if there is no abnormality in the review. If you need to do painless gastroscopy or prepare for pregnancy, it is recommended to consult a doctor in time and under the guidance of the doctor.
