Posted by Callie Torres
April 01, 2025

A gastroenterologist is a medical specialist who focuses on diagnosing, treating, and managing disorders of the gastrointestinal (GI) tract, which includes the esophagus, stomach, liver, pancreas, small and large intestines, and rectum. Becoming a gastroenterologist requires extensive training: completing a Doctor of Medicine (MD) or Doctor of Osteopathic Medicine (DO) degree, a 3-year internal medicine residency, and a 3-year gastroenterology fellowship. On a day-to-day basis, gastroenterologists perform a wide range of diagnostic and therapeutic procedures including endoscopies and colonoscopies, manage chronic conditions like inflammatory bowel disease and liver disorders, and provide preventive care such as cancer screenings. Their work is critical in identifying and treating complex GI conditions, improving patients’ digestive health, and ensuring timely intervention in life-threatening situations. In this article, we will discuss what is a gastroenterologist, what they do, how to become one, their salary, training specifics, lifestyle and more.

What is a Gastroenterologist?

A gastroenterologist is a medical specialist who manages diseases of the gastrointestinal tract, pancreas, and liver. They perform tasks such as diagnosing conditions through consultations, reviewing medical histories, and interpreting diagnostic tests. Common conditions they treat include gastroesophageal reflux disease (GERD), peptic ulcers, irritable bowel syndrome (IBS), Crohn’s disease, ulcerative colitis, liver diseases like hepatitis, and pancreatic disorders. Gastroenterologists perform critical procedures such as endoscopic ultrasounds, sigmoidoscopies, polypectomies, and liver biopsies, as well as advanced interventions like endoscopic retrograde cholangiopancreatography (ERCP) to diagnose and treat bile duct and pancreatic duct conditions. Their role is pivotal in providing both preventive care—such as colorectal cancer screenings—and acute care for emergency GI issues.

What do Gastroenterologists do?

Gastroenterologists are medical specialists focused on diagnosing, treating, and managing conditions of the GI tract, which includes the esophagus, stomach, liver, pancreas, intestines, and rectum. In the office setting, GI docs conduct comprehensive patient evaluations, including detailed medical histories and physical examinations. They use a range of diagnostic tests, such as blood tests, stool tests, and imaging techniques like abdominal ultrasounds and CT scans. They also perform in-office procedures, like administering breath tests for detecting bacterial overgrowth or lactose intolerance and performing hemorrhoid banding or ligation for hemorrhoid treatment.

In addition to in-office care, GI docs perform various procedures to diagnose and treat GI conditions. Endoscopic procedures are a significant part of their practice, which include supper endoscopy (esophagogastroduodenoscopy or EGD), colonoscopy, and sigmoidoscopy, which allow for direct visualization and biopsy of the GI tract. They manage conditions such as gastroesophageal reflux disease (GERD), inflammatory bowel disease (IBD) including Crohn’s disease and ulcerative colitis, celiac disease, irritable bowel syndrome (IBS), peptic ulcer disease, and liver disorders like hepatitis. Beyond diagnostics, they can perform therapeutic procedures such as polypectomy during colonoscopy, treating GI bleeding, and placing feeding tubes or stents within the liver, gallbladder, and pancreas. These interventions are critical for detecting early signs of cancer, managing chronic GI conditions, and improving patient quality of life.

How to become a Gastroenterologist?

To become a gastroenterologist, one must complete pre-medical requisites, attend medical school, pass board examinations, match into internal medicine residency, match into gastroenterology fellowship, and complete additional subspecialty board exams. The journey will start well before medical school. As a pre-medical student, you should focus on excelling in your undergraduate studies, particularly in the sciences, to build a strong academic foundation. It’s essential to complete pre-med requirements, which often include courses in biology, chemistry, physics, and mathematics. Participating in extracurricular activities such as volunteering in healthcare settings, shadowing physicians, and engaging in research can further bolster your medical school application. After gaining admission to medical school, the next four years will involve rigorous coursework and clinical rotations to provide a comprehensive understanding of various medical fields. During this time, it’s crucial to perform well academically and gain exposure to specialties that interest you, including gastroenterology. Joining interest groups and seeking out mentors in the field can provide invaluable guidance and early insight into the specialty.

Following medical school, the next step is to enter an internal medicine residency, which typically lasts three years. During residency, you will receive broad training in diagnosing and managing a wide array of medical conditions, honing your clinical skills through rotations in various subspecialties, including cardiology, pulmonology, and, importantly, gastroenterology. Residents must balance patient care responsibilities with ongoing education through lectures, conferences, and self-study. Developing strong relationships with mentors and demonstrating a keen interest in gastroenterology can lead to opportunities for specialized training and research in GI-related fields. Throughout residency, it is vital to excel in both clinical performance and on standardized tests, such as the Internal Medicine Board Exam, as this will make you a competitive candidate for fellowship programs.

After completing an internal medicine residency, you will need to apply for a gastroenterology fellowship, which typically lasts three years. This specialized training program focuses specifically on diseases of the gastrointestinal tract, liver, and pancreas. During your fellowship, you’ll receive extensive training in advanced diagnostic and therapeutic procedures, such as endoscopies, colonoscopies, and liver biopsies. Fellows also engage in research projects to contribute to the field’s body of knowledge and may have the opportunity to present their findings at national conferences. Throughout the fellowship, you’ll gain in-depth knowledge and hands-on experience in managing complex GI disorders, allowing you to develop the expertise required to excel as a gastroenterologist. Completing a fellowship is the final step before obtaining board certification in gastroenterology, which signifies that you have met all the requirements and are fully qualified to practice as a specialist in this field.
