What are the risks of an endoscopy?

Endoscopy is a standard medical procedure. Although rare, all procedures have some risks.

  • The instrument may tear the wall of the throat, stomach, or upper intestine, and may require surgery.
  • There may be adverse drug reactions or heart/breathing complications.
  • Bleeding (Bleeding may occur, usually when tissue or polyps are removed).
  • There may be discomfort during and after the procedure.
