Our focus is on the digestive system. Colonoscopy; acid reflux; Barrett's esophagus; Dr. Abram Eisenstein

Today's focus is on the digestive system.  When should we get our first colonoscopy and which procedure is better – the traditional or virtual colonoscopy? We'll also talk about the best way to avoid acid reflux, and how to treat it if we get it.  We'll also answer why Barrett's esophagus is becoming a more common condition. Dr. Abram Eisenstein, a clinical professor of medicine at The University of Texas Southwestern Medical School and the director of gastroenterology at Cooper Clinic in Dallas, joins us today. Dr. Eisenstein answers calls.
