For cardiac concerns, you trust a cardiologist. For a broken bone, you see an orthopedic surgeon. Similarly, your gastrointestinal concerns are best-entrusted to a GI Specialist. Unlike doctors from other specialties who perform GI procedures without specialty training in gastroenterology, GI doctors train for years on endoscopy and the conditions being evaluated. With a colonoscopy, for example, research shows that gastroenterologists are more likely to evaluate the entire colon for colon disease and detect what’s wrong, and their patients experience fewer complications.
