Thomas Lyles, M.D.

Dr. Lyles is a board-certified gastroenterologist at HEB Hospital in Bedford, TX. After graduating from medical school, he completed both an internal medicine residency and GI fellowship at the University of Texas-Southwestern/Parkland in Dallas. During his fellowship, he had a special interest in inflammatory bowel disease (IBD) and trained in an IBD-specific clinic. Dr. Lyles has been practicing as a general gastroenterologist with Digestive Health Associates of Texas since July 2013.

He has worked as both a GI hospitalist and in a traditional office-based practice, which gives him a unique perspective in evaluating GI conditions. Dr. Lyles has been trained in upper endoscopy, colonoscopy, polyp removal, and treating gastrointestinal bleeding in both the upper and lower GI tract. He has a special interest in inflammatory bowel disease (IBD), including ulcerative colitis and Crohn’s disease.

Dr. Lyles sees most of his patients through physician referrals from primary care physicians (PCPs), internists, general surgeons, and OB/GYNs. He is happy to see any patient suffering from a GI condition.
