Does it hurt to do gastroscopy? Excuse me, where can Songgang do painless gastroscopy?

Songgang People's Hospital and Songgang Fuya Hospital are both acceptable. Generally, before painless gastroscopy, you must abstain from drinking water, that is, you can't eat or drink water for at least 4 hours. If you have eaten mixed food before, you should fast for more than 6 hours; If you eat food with high fat content, you need to fast for more than 8 hours to ensure the emptying state of the stomach cavity and medical safety, and avoid suffocation due to food residue, water and other contents flowing back to the esophagus or even the oral cavity under anesthesia. Do painless gastroscopy also need someone to accompany, I wish Ankang!
