The risks of painless gastroscopy are generally low, but some risks do exist. Gastroscopy is able to look at the state of the mucous membranes in a number of areas, including the esophagus, stomach, and duodenum, and can help determine the presence of upper gastrointestinal tract pathology. Painless gastroscopy requires an injection of anesthetic medication, which can reduce discomfort, but the risks of gastroscopy remain. A small portion of the population is allergic to anesthesia drugs, which may cause breathing difficulties, or even respiratory arrest, and many other adverse reactions, which carry a certain degree of risk. In addition, the painless gastroscopy procedure may also cause damage to the gastric mucosa, causing bleeding, which has a certain impact on the body. Whether to perform painless gastroscopy should consult a professional physician, under the guidance of the physician to carry out the examination, not to judge on their own.
