"I am excited about the latest advances in the field of gastroenterology. New technologies and techniques allow us to treat, cure, and prevent GI diseases in ways that were previously unthinkable."
Dr. Ketan K. Shah is a board-certified, fellowship-trained gastroenterologist. His extensive and unique training, skills, and accomplishments make him among the top young gastroenterologists in the nation.
Dr. Shah has expertise treating a broad range of gastrointestinal conditions, including GERD, eosinophilic esophagitis, H. pylori infections, gastritis, Barrett’s esophagus, motility disorders, liver disease, pancreatic and bile duct conditions, celiac disease, irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), and GI cancers. He regularly performs diagnostic and advanced endoscopy and colonoscopy procedures, including underwater polyp removal for higher patient comfort and success rates. He is also skilled at performing colonoscopies without sedation for select patients, so they may comfortably observe their own exam while avoiding the risks and inconvenience associated with sedation.
Dr. Shah maintains an extremely high polyp-detection rate – which is something like a batting average – during colon cancer screenings of more than 50%, compared to the national average of 20%. Patients of physicians with higher detection rates have a lower risk of developing colon cancer, advanced-stage colon cancer, and dying from colon cancer.
Dr. Shah received his bachelor of science in biology with a specialization in computing at UCLA, where he graduated with honors. He earned his medical degree from USC’s Keck School of Medicine. While at USC, he concurrently obtained his master of business administration. Dr. Shah continued his postgraduate medical training at Duke University, where he completed a dual residency in internal medicine and pediatrics. Finally, he completed his fellowship training in gastroenterology from UC Irvine, where he trained under world-renowned GI specialists.
Dr. Shah has received advanced training in pediatric gastroenterology, including pediatric endoscopy and pediatric IBD. He has also published studies in peer-reviewed medical journals and spoken at national conferences. His research has led to the discovery of multiple childhood risk factors that increase the chance of developing adult-onset gastrointestinal illnesses. Dr. Shah’s research team was the first in the world to establish a direct link between pediatric GERD, Barrett's esophagus, and esophageal cancer. Dr. Shah was selected to present his research at the North American Conference of Gastroenterology Fellows.
Dr. Shah has been honored with several national awards and achievements. He won the American College of Gastroenterology’s "GI Jeopardy" national championship and received the Fellowship2Leadership award, as well as the UC Irvine Excellence in Research award.
Dr. Shah lives with his family in Orange County. He is fluent in Spanish and proficient in Gujarati and Hindi. In his spare time, Dr. Shah enjoys photography, technology, and skiing. He is also an accomplished violinist.
