FAQs About the Practice

What is a Gastroenterologist?

A gastroenterologist is a physician who specializes in the prevention, diagnosis, and treatment of digestive and liver diseases. To be a fully-credentialed gastroenterologist, a physician must complete an additional fellowship training beyond their general internal medicine residency.

At Providence Gastroenterology and Liver Associates, our gastroenterologists are certified to be proficient in the performance of safe and effective endoscopic procedures. They are duly licensed in the state of Texas and are board certified by the American Board of Internal Medicine with subspecialty in Gastroenterology.

What makes Providence Gastroenterology and Liver Associates different from other gastroenterology clinics?

Our gastroenterologists not only perform routine colonoscopy, they strive to provide a caring, comprehensive, and state-of-the-art evaluation and treatment of patients with an array of digestive and liver disorders. Beyond the typical gastroenterology services, we offer diagnosis and management of advanced liver disease, liver transplant evaluation, gastrointestinal cancers, and complicated pancreatic-biliary conditions. We have on staff a transplant hepatologist and an interventional endoscopist who both completed advanced training in addition to their prescribed, 3-yr fellowship in gastroenterology. Two of our gastroenterologists also hold advanced degrees in Clinical Research and Public Health; in addition to their medical doctorates. Our gastroenterologists are up-to-date with the latest clinical trials and guidelines in the care of patients with digestive and liver diseases.

What is the gastrointestinal tract?

The gastrointestinal, or “GI” tract for short, encompasses the organs related to digestion, nutrition, and metabolism. These organs include the esophagus, stomach, small and large intestines, the pancreas, liver, gallbladder, and bile ducts.

The GI system is important in the overall well-being of the human body. It is often the site of disorders such as abdominal pain, inflammation, ulcers, internal bleeding, obstruction, infection, and even cancer.

A gastroenterologist is a physician who has specialized knowledge and skill to care for you in the event that you have a GI tract disorder.
