In the Chicago area

Our Chicago listings cover the city and its Illinois suburbs: Cook County, DuPage County, Lake County, Will County, Kane County and Kendall County. Most McHenry County providers, such as those in Crystal Lake and Woodstock, are listed under the Rockford area.

The largest share of listings is inside the City of Chicago, where Northwestern Medicine, Rush, UChicago Medicine and UI Health have their main campuses. The rest are spread across the suburbs. In the north suburbs, look at Evanston, Skokie, Park Ridge and Arlington Heights, served by Endeavor Health and Advocate. In the west suburbs, Loyola Medicine in Maywood, UChicago Medicine AdventHealth in Hinsdale and Northwestern Medicine in Winfield are large hubs, with Duly Health and Care offices across DuPage and Will counties. In the south suburbs, Oak Lawn and Orland Park have the most choices.

Ascension also has clinics in the northwest suburbs, and independent specialty groups practice all over the metro. Many large systems have several offices, so you can often see the same practice closer to home.

Gastroenterologists here practice through Northwestern Medicine's Digestive Health Institute, Rush, Endeavor Health and Loyola, plus large independent groups like GI Alliance of Illinois and Midwest Digestive Health & Nutrition. Many groups run their own endoscopy centers, so ask where your colonoscopy would be done.

How to choose a gastroenterologist

A gastroenterologist, or GI doctor, diagnoses and treats problems of the digestive tract: the esophagus, stomach, intestines, colon, liver, pancreas and gallbladder. People see one for heartburn that won't go away, ongoing belly pain, diarrhea or constipation, bleeding, Crohn's disease or ulcerative colitis, and for colonoscopies.

Start with the kind of care you need. Many GI doctors handle a wide range of problems, but some focus on one area:

  • General gastroenterologists handle most needs: reflux, ulcers, irritable bowel syndrome, screening colonoscopies and follow-up on abnormal tests.
  • Inflammatory bowel disease (IBD) specialists manage Crohn's disease and ulcerative colitis over the long term.
  • Advanced endoscopists do complex scope procedures, such as removing large polyps or treating bile duct and pancreas problems.
  • Hepatologists focus on the liver. Many are gastroenterologists with extra liver training.

If you're not sure, a general gastroenterologist is the right first stop. They'll refer you on if you need a subspecialist.

Check credentials. Board certification in gastroenterology shows a doctor has finished specialty training and passed a certification exam. You can look up any doctor's certification for free on the American Board of Internal Medicine website [1]. Our listings show the credentials doctors report in the federal NPI registry, but we don't verify board certification.

Know if you're due for a colonoscopy. Experts recommend colorectal cancer screening for adults ages 45 to 75 [2]. A colonoscopy is one option. Some people can start with a stool test instead. Ask your primary care doctor which test fits you, and whether your family history means you should start earlier.

Confirm insurance before you book. Practices change the plans they accept, so call the office or check your insurer's directory. HMO plans usually need a referral first. Medicare Part B covers medically necessary specialist visits; you typically pay 20% of the Medicare-approved amount after your deductible [5].

Ask where procedures are done. Colonoscopies and other scopes happen in a hospital or a separate endoscopy center. The location can change what you pay, so ask before you schedule.

Know when not to wait. Vomiting blood or material that looks like coffee grounds, black or tar-like stool, or feeling faint, confused or cold and clammy with belly symptoms need emergency care, not an appointment [4]. Call 911.

Frequently asked questions

Do I need a referral to see a gastroenterologist?

It depends on your insurance. Most HMO plans require a referral from your primary care doctor before they'll cover a specialist visit. PPO plans and traditional Medicare usually don't. Some GI practices also want a referral or recent test results before they book you, especially for a procedure, so call ahead and ask what to bring.

At what age should I get a colonoscopy?

The U.S. Preventive Services Task Force recommends colorectal cancer screening for adults ages 45 to 75. A colonoscopy is one way to screen, and stool tests are another. People with a family history of colon cancer, certain polyps or inflammatory bowel disease may need to start earlier or screen more often. Ask your doctor what's right for you.

Does Medicare cover a screening colonoscopy?

Yes. Medicare Part B covers a screening colonoscopy once every 120 months for most people, or once every 24 months if you're at high risk. There's no minimum age. You pay nothing for the screening if your doctor accepts assignment. If a polyp is removed during the test, you may owe a share of the cost.

What happens at a first GI appointment?

Expect questions about your symptoms, diet, bowel habits, medications and family history, plus a physical exam. The doctor may order blood work, a stool test, imaging or a scope procedure such as an upper endoscopy or colonoscopy. Bring a list of your medications and any recent lab results, scans or procedure reports.

How do I know if a gastroenterologist is board certified?

Look the doctor up on the American Board of Internal Medicine's free "Verify a Physician" tool, which shows whether they're certified in gastroenterology. Our listings show the credentials doctors report to the NPI registry, but we don't verify certification ourselves.
