What is gastroenterology?

Have you ever thought about how food moves through your body? A gastroenterologist has, along with how the body absorbs nutrients and removes waste. Gastroenterology focuses on the health of the digestive system—esophagus, stomach, small intestine, colon and rectum, pancreas, gallbladder, and bile ducts—and liver. 

St. Luke’s Health is committed to advancing gastroenterology while helping our communities grow healthier and stronger. Our expertise and our belief in the power of humankindness allows us to care for patients with some of the most complex conditions. 

Our experienced board-certified gastroenterologists serve patients throughout our health system. No matter where you live or which location you choose, you can trust that we will provide the same patient-centered standards of quality care to everyone.

Frequently asked questions

You would be referred to a gastroenterologist by a primary care provider if you're experiencing unexplained or frequent digestive issues. A gastroenterologist also performs colorectal cancer screenings.

The type of insurance plan you use will determine if you need a referral from your primary care physician to see a gastroenterologist. For example, a PPO generally does not require a referral, whereas HMOs typically do.

Your first appointment will be used to assess your symptoms and conditions. Come prepared with a list of medications you currently take, your personal and family medical history, and the symptoms you’ve been experiencing.

A few steps you might need to follow before your first gastroenterology appointment include:

  • Follow any pre-appointment dietary restrictions
  • Prepare a list of your symptoms and any medications you take
  • Bring a support person
  • Make a list of questions for your physician
  • Be prepared to take notes
