Gastroenterologists specialize in all aspects of gastrointestinal disease. 

Gastrointestinal disease can affect the esophagus, stomach, small intestine, colon and rectum, pancreas, gallbladder, bile ducts and liver.

Marshfield Clinic Gastroenterologists diagnose and treat all diseases and conditions that affect the gastrointestinal (GI) tract.

The GI tract is a system, beginning with the esophagus and ending with the anus, that processes food.

It extracts nutrients and expels waste.

Disease or other conditions can disrupt the process.

Gastroenterologists help determine where the problem is and recommend treatment options to patients.

You can solve some GI problems with diet and lifestyle changes. However, other​ situations require medicine to remedy.

In some cases, surgery may be the best option.

Gastroenterologists also perform preventive procedures such as colonoscopies, which is the best method of spotting colon cancer.

Most people age 50 and above need periodic colonoscopies to guard against colon cancer. Check with your doctor to see what’s right for you.

Some Gastroenterologists treat children.

Below are some of the conditions and treatments associated with Gastroenterologists.​
