Stomach pain, blood in stool, or constant heartburn — these are signs many people ignore until they get worse. A gastroenterologist is the doctor who deals with your digestive system: esophagus, stomach, liver, pancreas, small and large intestines. If your gut is giving you trouble, a specialist can find answers faster than a generalist.
Common problems include acid reflux, ulcers, irritable bowel syndrome (IBS), inflammatory bowel disease (IBD) like Crohn’s and ulcerative colitis, gallbladder issues, hepatitis, and unexplained weight loss. They also handle colon cancer screening and follow-up after abnormal tests. Many tests are outpatient and routine, but they tell you exactly what’s going on.
How they diagnose you
Expect a clear sequence: medical history, focused exam, and targeted tests. Blood work checks for infection, inflammation, and liver function. Stool tests look for bleeding or infection. Imaging like ultrasound, CT, or MRI can spot structural problems. Endoscopy and colonoscopy are common tools — thin scopes let the doctor look inside and take tiny biopsies if needed. These procedures are usually done with sedation and quick recovery.
Bring a list of symptoms with timing and triggers. Note medications, supplements, and past surgeries. Track food that seems to cause symptoms for a week or two before the appointment. If you’ve had recent tests, bring the results or arrange to have them sent. Ask about insurance coverage and sedation plans for procedures.
Questions worth asking
What tests do you recommend and why? Is this likely temporary or chronic? Are there simple lifestyle changes I should try first? What side effects should I watch for with suggested medications? How often should I get screening tests like colonoscopies based on my age and risk?
Treatment options you might see
Treatments range from diet changes and over-the-counter meds to prescription drugs, procedures, or surgery. A gastroenterologist will try the least invasive effective option. For example, acid reflux often starts with diet tweaks and proton pump inhibitors. IBD usually needs stronger, longer-term medication. Colon polyps found on a colonoscopy are often removed during the same procedure.
Finding the right specialist
Look for a board-certified gastroenterologist with experience in the issue you have. Ask your primary care doctor for referrals, read clinic reviews, and check if the specialist accepts your insurance. Telehealth can be useful for follow-ups and medication checks, but many diagnoses need in-person tests.
When to seek emergency care
Head to the ER for severe abdominal pain, high fever with belly pain, fainting, persistent vomiting, or large amounts of blood in vomit or stool. These signs can mean a serious problem that needs urgent attention.
This straightforward approach helps you get the right care from a gastroenterologist without guessing.
If cost is a concern, ask about generic medicines, patient assistance programs, and local clinics that offer sliding-scale fees. SingleCare lists coupons and price comparisons that may lower your out-of-pocket costs for tests and medicines and lab fees.
