What is a Gastroenterologist?
A gastroenterologist is a physician who specializes in diagnosing and treating conditions of the gastrointestinal (GI) tract and liver. This specialty requires extensive training beyond medical school, including a three-year internal medicine residency and a fellowship of three or more years focused on gastroenterology. Their expertise covers a wide range of issues within the complex digestive system.
The Organs of the Digestive System
The digestive system is responsible for processing food, absorbing nutrients, and eliminating waste. Gastroenterologists address problems in all its components:
- The Esophagus: Moves food to the stomach.
- The Stomach: Digests food with acid and enzymes.
- The Small Intestine: Absorbs most nutrients.
- The Large Intestine (Colon): Absorbs water and stores waste.
- The Rectum and Anus: The terminal part of the GI tract.
- Accessory Organs: The liver, pancreas, and gallbladder, which support digestion.
Conditions Treated by a Gastroenterologist
Gastroenterologists manage a broad spectrum of digestive disorders. Common conditions include GERD, IBD (Crohn's and ulcerative colitis), IBS, and Celiac Disease. They also treat liver disease, stomach ulcers, pancreatitis, gallstones, and are involved in colorectal cancer screening and detection.
When to Consider Seeing a Specialist
While your primary care physician can handle many digestive concerns, a gastroenterologist is recommended for persistent, severe, or unexplained symptoms such as chronic abdominal pain, heartburn unresponsive to treatment, changes in bowel habits, blood in stool, difficulty swallowing, unexplained weight loss, or chronic nausea/vomiting. They are also the specialists for routine colon cancer screenings or if you have a family history.

What to Expect at a Gastroenterology Appointment
Your first appointment will typically involve a detailed discussion of your health history and symptoms, followed by a physical examination. The gastroenterologist may then order diagnostic tests like blood work, stool samples, or imaging studies. If necessary, they may recommend endoscopic procedures, such as an upper endoscopy or colonoscopy, to visually inspect the digestive tract and potentially take biopsies. Following the diagnosis, a personalized treatment plan will be developed, which may include lifestyle adjustments, medication, or further procedures.
How to Find a Reputable Gastroenterologist
To find a suitable specialist, consider getting a referral from your primary care physician. Medical association websites like the American College of Gastroenterology (ACG) offer search tools for finding board-certified specialists. Checking hospital affiliations and reading patient reviews can also be helpful.
