Division of Gastroenterology Make an Appointment Ask a Question Refer Patient Jeffrey B. King, MD Division Chief What do we do? We have a comprehensive program to diagnose and treat the entire range of GI illnesses including liver disease, biliary disorders, inflammatory bowel disease, GERD and esophageal disorders, pancreatic disease, gut motility disorders and functional disorders of the gut. We also diagnose and treat digestive system disorders affecting the esophagus, stomach, small and large intestines, rectum, liver, gall bladder and pancreas. At National Jewish Health, we treat many chronic diseases that have secondary symptoms affecting the digestive system. For example, GE reflux can occur in up to 80 percent of asthma patients. There are also many gastrointestinal issues associated with food intolerances and allergies and autoimmune diseases. Why National Jewish Health? We partner with other specialty areas at National Jewish Health to determine interrelated causes of uncontrollable asthma and maximize GI therapy for improved health. The program is also concerned with the importance of colon cancer screening to ensure that this preventable disease is detected early. We offer special expertise in GI motility disorders, pulmonary related GI conditions, GI cancer screening and treating GI malignancies. Jeffrey B. King, MD + × Jeffrey B. King, MD Jeffrey B.
