Does it hurt to do gastroscopy

Gastroscopy

is a common endoscopic examination used to examine lesions in the digestive tract such as the esophagus, stomach, and duodenum. Gastroscopy generally needs to be carried out under fasting state. Before the examination, doctors usually give patients local anesthesia, such as spraying anesthetics in the throat or containing anesthetic tablets in the mouth, etc., to alleviate discomfort during the examination, and then insert a soft endoscope into the patient's mouth, esophagus, stomach and duodenum. During insertion, nausea and other discomfort may be caused, but there is usually no obvious pain, and most patients can tolerate this feeling.
