What is a Gastroenterologist and How Can They Help You?

  • Focuses on the alimentary canal, hepatobiliary system, and digestive organs
  • Conducts patient assessments, orders diagnostic investigations, performs endoscopic examinations, interprets tissue pathology
  • Manages gastroesophageal reflux, inflammatory bowel conditions, functional bowel disorders, hepatic disease, pancreatic disorders, and colonic polyps
