Understanding What a Gastroenterologist Does

A gastroenterologist is a medical doctor who specializes in treating diseases and conditions of the digestive system. This system includes your mouth, esophagus, stomach, small intestine, large intestine (colon), rectum, pancreas, and liver. According to the American College of Gastroenterology, there are approximately 13,000 gastroenterologists practicing in the United States. These doctors receive at least 13 years of training after high school: four years of medical school, three years of general internal medicine residency, and three years of gastroenterology fellowship training.

Gastroenterologists diagnose and treat a wide range of conditions. Common reasons people see these specialists include chronic heartburn, irritable bowel syndrome (IBS), inflammatory bowel disease (IBD) like Crohn's disease and ulcerative colitis, celiac disease, gallstones, pancreatitis, liver disease, and colorectal cancer screening. They also manage conditions like gastroparesis, which affects how the stomach moves food, and Barrett's esophagus, a precancerous condition.

These specialists perform both diagnostic procedures and treatments. Diagnostic procedures help doctors see inside your digestive tract and collect tissue samples. Treatment procedures may involve removing polyps, stopping bleeding, dilating narrowed areas, or placing stents. About 14 million colonoscopies are performed each year in the United States, making this one of the most common gastroenterology procedures.

Your primary care doctor may refer you to a gastroenterologist when symptoms persist despite initial treatment, when conditions require specialized equipment or expertise, or when screening procedures are needed. Common referral reasons include persistent diarrhea lasting more than four weeks, difficulty swallowing, unexplained weight loss, persistent abdominal pain, and signs of gastrointestinal bleeding.

Practical Takeaway: Before your appointment, write down what digestive symptoms you've experienced, how long they've lasted, and what seems to make them better or worse. This information helps your gastroenterologist understand your condition from the start.

Preparing Your Medical History and Records

Your gastroenterologist needs detailed information about your medical background to provide appropriate care. Start by making a list of all current medications you take, including over-the-counter drugs, vitamins, and supplements. Be specific about dosages and how often you take each item. Some medications affect digestive function or can interfere with diagnostic procedures. For example, blood thinners may need to be stopped before certain procedures, and some diabetes medications require adjustment on procedure days.

Compile information about your surgical history, including any previous abdominal or digestive surgeries. Previous surgeries can affect how procedures are performed or interpreted. For instance, if you've had your gallbladder removed, your bile duct anatomy differs from someone who hasn't. Document previous digestive procedures you've had, including colonoscopies, upper endoscopies, or imaging studies. Knowing when your last colonoscopy was performed helps determine if another screening is needed, since current guidelines recommend screening colonoscopies every 10 years for average-risk adults, or more frequently for those with certain risk factors.

Keep records of any food allergies or medication allergies you have, especially reactions to sedatives or contrast dyes used in imaging procedures. Note any family history of digestive diseases, as conditions like colorectal cancer, celiac disease, and IBD often run in families. Research from the National Institutes of Health shows that having a first-degree relative with colorectal cancer increases your own risk, potentially affecting screening recommendations.

Request copies of previous medical records from other providers, particularly imaging reports, lab results, and specialist notes. If you've been evaluated for your condition elsewhere, these records provide valuable context. Many medical offices can send records electronically to your gastroenterologist's office before your appointment. You might also request these records to bring with you in case electronic transfer doesn't occur in time.

Practical Takeaway: Create a one-page document listing all medications (with doses), allergies, surgeries, and relevant family history. Bring this to your appointment along with any imaging films, lab reports, or previous procedure reports you have available.

What to Bring and How to Prepare for Your Visit

Several items should accompany you to your gastroenterology appointment. Bring your insurance card and photo identification, as the office staff need this information for billing and verification purposes. Arrive at least 10 to 15 minutes early to allow time for check-in and paperwork. Many offices now offer online check-in through their patient portal, which can streamline this process.

Wear comfortable, loose-fitting clothing that allows easy access to your abdomen if the doctor needs to perform a physical examination. Avoid tight belts or restrictive clothing. If you're having a procedure scheduled during your visit or if one is planned for soon after, follow specific preparation instructions your doctor provides. For colonoscopies, patients typically fast for 24 hours and use a bowel preparation solution to clear the colon. For upper endoscopies, fasting for 6 to 8 hours beforehand is standard. These preparations are essential for the procedure to be effective and safe.

Bring a list of questions you want to ask, as appointments often move quickly and it's easy to forget what you wanted to discuss. Questions might include: "What do you think is causing my symptoms?", "What tests or procedures do I need?", "What are my treatment options?", "What lifestyle changes might help?", "When will I get results?", and "Do I need follow-up appointments?" Having these written down ensures you cover important topics.

If you're anxious about your appointment, consider letting office staff know when you call to schedule. They can provide information about what to expect and may note your anxiety in your chart so the doctor is aware. Some patients benefit from bringing a trusted family member or friend to appointments, particularly if procedures are planned, since sedation may be used and you'll need someone to drive you home afterward.

Practical Takeaway: Check in with your doctor's office one to two days before your appointment to confirm you have correct preparation instructions and to ask any preliminary questions about what to expect.

During Your Appointment: What to Expect

When you enter the examination room, the medical assistant or nurse will check your vital signs (blood pressure, heart rate, temperature, and respiratory rate) and may ask you to describe your symptoms. They'll verify your medication list and allergies against your previous paperwork. This typically takes 10 to 15 minutes. Be honest about your alcohol use, smoking history, and any symptoms you might feel embarrassed discussing, as this information affects your care. Gastroenterologists regularly discuss digestive issues and don't make judgments about bathroom habits or digestive symptoms.

The doctor will review your medical history, ask detailed questions about your symptoms, and perform a physical examination. The physical exam typically involves pressing on different areas of your abdomen to check for tenderness, masses, or other abnormalities. The doctor listens to your abdomen with a stethoscope to evaluate bowel sounds. This examination usually takes 5 to 10 minutes. The doctor may ask about diet, stress levels, and how symptoms affect your daily life.

Based on your symptoms and examination, the doctor will explain their initial assessment and recommend diagnostic tests or procedures. Common diagnostic approaches include blood tests, stool samples, imaging studies (ultrasound, CT scans, MRI), or endoscopic procedures. The doctor will explain why each test is being recommended and what it will show. You'll learn about the risks and benefits of each option. This discussion allows you to make informed decisions about your care.

If a procedure is recommended, the doctor will describe exactly what happens during the procedure, how long it takes, what preparation is needed, and what recovery looks like. For procedures involving sedation, the doctor discusses which sedation method will be used and arranges for someone to drive you home. If you have questions or concerns about any recommended procedure, this is the time to discuss them. Never feel rushed to agree to a procedure you don't understand.

Practical Takeaway: Ask the doctor to explain their findings and recommendations in plain language. Request written instructions for any preparation or follow-up care needed, and confirm the date and time of any scheduled procedures before leaving.
