Yanna Ko is a gastroenterologist based in Hospital Rd, Sydney, NSW 2139, Australia. If you’re dealing with gut symptoms that keep coming back, it helps to have someone who looks closely at what’s going on in the stomach and the bowel.
Her clinical focus includes inflammatory bowel conditions such as ulcerative colitis and Crohn’s disease, plus related issues like colitis and hemorrhagic proctocolitis. In many cases, these problems can affect day-to-day life, so care usually aims to bring things under control and keep symptoms steady over time.
Yanna also looks after people with ongoing stomach and upper gut problems. This can include chronic erosive gastritis, and conditions linked to long-term irritation of the stomach lining. Barrett’s oesophagus is also part of her work, which matters because the oesophagus can change over time and needs ongoing monitoring.
Infections are another part of the picture. She treats viral gastroenteritis, and she also manages Helicobacter pylori infection, a common cause of stomach irritation. At times, treating H. pylori can make a real difference to ongoing discomfort.
Some patients have immune-related gut and stomach concerns. Common variable immune deficiency (CVID) and lymphoid hyperplasia are included in her listed areas of care, along with necrosis findings seen in some bowel or digestive tissue investigations. These situations can be complex, so it often comes down to using test results in context and taking things step by step.
The profile information provided here doesn’t include details on her years of experience, formal education, or any research background. It also doesn’t list specific clinical trials.

Overall, Yanna Ko’s listed work covers a broad range of gastroenterology needs, from long-term bowel inflammation to stomach lining issues and infections. For people in Sydney and beyond who want clear, practical medical care for digestive health, that mix can be a good fit.
