Do gastroscopy and colonoscopy painful

Gastroscopy and colonoscopy are painful to analyze on a case-by-case basis.

For general gastroscopy and colonoscopy, a catheter is inserted into the patient's stomach from the mouth, which may cause cough, nausea, vomiting, pain, etc. For colonoscopy, a catheter is inserted into the patient's intestine from the anus, which may cause abdominal pain, bloating, nausea, etc., which is relatively painful. However, if painless gastroscopy and enteroscopy are used, anesthesia is required, and patients will lose consciousness during the examination, so they will not feel pain.
