Upper endoscopy, also known as EGD, is a procedure in which a thin scope with a light and camera at its tip is used to look inside the upper digestive tract—the esophagus, stomach, and first part of the small intestine, called the duodenum.  

This procedure is used to identify causes of abdominal or chest pain, nausea and vomiting, ulcers, tumors, heartburn, inflammation, bleeding and swallowing problems.


In his free time, he enjoys running, ice hockey, and spending time with his wife and children.
