Upper endoscopy, also called EGD, allows a gastroenterologist to examine the upper digestive tract. Biopsies or selected treatments can be performed during the examination.
What to expect
An empty stomach is needed. Follow the endoscopy team’s exact fasting and medicine instructions, including advice about diabetes medicines and anticoagulants. Arrange transport if sedation is used.
A flexible endoscope is guided through the mouth into the esophagus, stomach and duodenum. Throat-numbing medicine and sedation may be used. Tissue samples are taken when indicated.
You are observed while sedation wears off. Temporary sore throat, bloating or nausea may occur. Follow the team’s advice on eating, driving and work. Biopsy results may take longer than the initial findings.
