What is Gastroenterology?

Gastroenterology is the study of the gastrointestinal (GI) tract of the body. A gastroenterologist diagnoses and treats diseases of the digestive organs, including the stomach, esophagus, intestines, pancreas, liver and gallbladder. This specialist treats conditions such as abdominal pain, nausea and vomiting, ulcers, diarrhea, cancer in the GI tract, and jaundice. A gastroenterologist also performs complex diagnostic procedures, including the use of endoscopes to see and treat internal organs.

How we work with your primary care doctor.
If you have been referred to us by your primary care physician, we send letters to your doctor to let them know what treatments we recommend and what procedures are performed.  He or she will receive a copy of your endoscopy results. 

We work together to ensure that your gastrointestinal disorder is being managed well.


Gastroenterology is a subspecialty of internal medicine.  Gastroenterologists must first complete seven or more years of medical school and postgraduate training in order to be Board Certified in Internal Medicine.  Then, for another two or three years, Gastroenterologists study conditions specific to the GI tract.
