Which professional specializes in diseases of the digestive system?

• A. Endoscopy technician
• B. Gastroenterologist
• C. Surgeon
• D. Dietitian

Answer: (B)

Gastroenterology is the medical field focused on diseases of the digestive system. A gastroenterologist is a physician who specializes in diagnosing and treating conditions that affect the entire GI tract—from the esophagus through the stomach, small intestine, and colon, as well as the liver, gallbladder, and pancreas. They manage common problems like GERD, ulcers, inflammatory bowel disease, hepatitis, and pancreatitis, and they often use procedures such as endoscopy and colonoscopy to visualize or sample parts of the digestive tract.

An endoscopy technician, while skilled with the equipment, does not diagnose or manage diseases. A surgeon may treat GI diseases surgically, but their role isn’t limited to the digestive system’s diseases as a specialty. A dietitian focuses on nutrition and dietary management to support health and disease treatment, not on diagnosing or treating digestive diseases.
