Risks and complications of an EGD test


In general, an EGD is a safe procedure. There’s a very slight risk that the endoscope will cause a small hole in your esophagus, stomach, or small intestine. If a biopsy is performed, there’s also a small risk of prolonged bleeding from the site where the tissue was taken.
Some people also may have a reaction to the sedatives and painkillers used throughout the procedure. These could include:
  • difficulty breathing or an inability to breathe
  • low blood pressure
  • slow heartbeat
  • excessive sweating
  • a spasm of the larynx
However, less than one out of every 1,000 people experience these complications.
