An esophagogastroduodenoscopy (EGD) is a low-risk diagnostic test where a flexible tube with a camera attached is inserted through the throat. The endoscope helps physicians obtain high-quality images of the patient’s digestive tract with minimal invasion. The endoscope is passed through the throat and brought down along the esophagus. There are several conditions that can require an EGD test including chronic heartburn, food regurgitation, persistent nausea, or difficulty swallowing. Doctors may also conduct an EGD test to determine if a treatment plan for diseases such as cirrhosis or Crohn’s disease is working well. Prior to taking the test, it is important that you tell your doctor about your medical history and if you are currently taking any medications or supplements so that they can guide you on how to prepare yourself before the test.
