Gastroenterology

Gastroenterology Care at National Jewish HealthThe National Jewish Health Gastroenterology (GI) Program in Denver, Colo., treats thousands of adults each year. Our program offers comprehensive, personalized care for all gastroenterology diseases. 

Our GI specialists also are experts at early detection and prevention of colon cancer. Our detection rate for  precancerous polyps averages about 65% with the national average much lower at 39%. This means we are better at catching cancer early when it's easier to treat and at reducing risk of developing colon cancer between colonoscopies.
