Dr. Kai Xia obtained her MD and PhD degrees magna cum laude from Harvard Medical School in 1999. She completed her residency in internal medicine and fellowship in gastroenterology/hepatology at the Brigham and Women’s Hospital, a Harvard Medical School teaching hospital in Boston. Following her residency, she became a faculty member and an attending physician at the Harvard Medical School and the Brigham and Women’s Hospital. Dr. Kai actively participated in teaching residents and fellows, attending both inpatient and outpatient services and conducting translational research. She published in multiple prestigious professional journals.
In 2005, Dr. Kai joined the Trinity Mother Frances Hospitals and Clinics as an attending physician. Subsequently she established the health system’s first Liver Clinic which now has instituted a well-established network and collaborations with two major academic centers, Baylor University Medical Center and University of Texas Southwestern Medical Center and their liver transplant programs in Dallas. In 2006, Dr. Kai was named the chief of the Department of Gastroenterology, Hepatology and Endoscopy at Trinity Mother Frances and in 2009 she was elected a member of the Trinity Clinic Board of Directors. She also holds three academic appointments as an associate professor of clinical medicine in the Division of Digestive and Liver Diseases at The University of Texas Southwestern Medical Center; at The University of Texas Health Science Center at Tyler; and as an active community faculty member at the Baylor University Medical Center and the Baylor Regional Transplant Institute.
Her clinical interests include liver diseases, general digestive diseases, women’s digestive health and preventive health. She does clinical consultation in all liver-related diseases and general digestive problems as well as performing screening, diagnostic and therapeutic upper endoscopies and colonoscopies. Dr. Kai Xia strives to provide the best quality and the most efficient patient care.
For our patients’ comment on care provided by Dr. Kai, please visit tmfhc.org/MyLife and watch the videos “My Life, My Health and My Journey”. Besides her clinical activities, she also promotes physician education and participates in national multi-center clinical trials and studies on liver diseases. She hosted the first Gastroenterology and Hepatology Updates in Tyler on April 25, 2009. Dr. Kai invited nationally and internationally distinguished speakers from Harvard Medical School in Boston, Mayo Clinic in Rochester and UT Southwestern Medical School in Dallas to update our regional physicians’ knowledge in the diagnosis and management of commonly encountered gastrointestinal and liver diseases. For the detailed program, please visit website tmfhc.org. Because of her achievements and contribution to the field, Dr. Kai has won awards and recognition from the Harvard Medical School in Boston, American College of Gatroenterology (ACG), American Society for Gastrointestinal Endoscopy (ASGE) and Trinity Mother Frances Hospitals and Clinics.
