Do gastroscope colonoscopy have risk

Gastroscopy and enteroscopy are risky, but usually the risk is relatively low.

Anesthesia is required for painless gastroscopy and enteroscopy. Anesthetics may cause adverse reactions such as respiratory depression, hypotension, arrhythmia, etc. Secondly, biopsy may be required for gastroscopy and enteroscopy, which may cause bleeding. In addition, if the stomach wall and intestinal mucosa are excessively dilated or the instrument is damaged during gastroscopy and enteroscopy, it may cause gastric and intestinal perforation. However, if the patient himself is not allergic to anesthetics and is operated by an experienced doctor in a regular hospital, the above risks generally do not occur.
