Esophagogastroduodenoscopy (EGD) is a diagnostic endoscopic procedure that visualizes the upper part of the gastrointestinal tract through the duodenum. When you are experiencing symptoms such as severe abdominal pain, chronic heartburn, vomiting blood, or any other GI symptoms, EGD can help determine the cause and make a clear diagnosis.
