About Us

Dr Marc Ostrofsky is a healthcare practitioner, specialising as a Physician (Gastroenterologist) at The Sandton Surgical Institution. Gastroenterology is an area of medicine that focuses on the health of the digestive system, or the gastrointestinal (GI) tract, as well as the liver. Gastroenterologists can treat everything from irritable bowel syndrome (IBS) to hepatitis C.

What does a gastroenterologist do?

Gastroenterologists primarily diagnose and treat GI conditions. If your primary care physician has noticed an issue involving your GI tract, they will most likely recommend you see a gastroenterologist for a more detailed assessment of the issue. Gastroenterologists perform endoscopic procedures, in which they use specialized instruments to view the GI tract and make a diagnosis. They don’t perform surgery, though in some cases, they may work closely with a GI surgeon. They primarily work in clinic or hospital settings.
