Natassia P. Tan is a gastroenterologist based in Melbourne, VIC. She looks after people with health issues that involve the gut, the liver, the bile ducts, and the gallbladder. If you’ve been dealing with ongoing stomach or liver symptoms, or you’ve had scans and blood tests that need a specialist view, she can help sort out what’s going on and what to do next.
Her clinical work covers a wide range of conditions. This includes bile duct problems like cholangitis and sclerosing cholangitis. She also treats cancers of the bile duct, as well as gallbladder disease such as gallstones and other gallbladder problems. In the liver space, she helps manage concerns like liver cancer, working with you and other health professionals to plan the next steps.
Natassia also sees patients for issues that affect the digestive tract more broadly. For example, gastrointestinal bleeding can be scary and stressful, and getting the cause right matters. She looks after people with bleeding related to the gastrointestinal system, including problems like peptic ulcers. Viral gastroenteritis is another common reason people book in, especially when symptoms like vomiting and diarrhoea don’t settle as expected.
Over time, she’s built experience in helping patients navigate these conditions, including what’s urgent, what can be managed step by step, and what may need further tests. At times, care can feel like a lot to take in. That’s why the approach is usually calm and practical, with clear explanations along the way.
Education details are not listed here, but the work is clearly grounded in gastroenterology care and the day-to-day reality of treating both common and more complex gut and liver conditions. Patients often need a mix of medical care and strong coordination, especially when symptoms involve the bile ducts or when cancer is part of the discussion.
Research and clinical trials are not detailed here either. If a trial is something that might fit a person’s situation, it can be discussed directly during appointments. For now, the focus stays on the basics that matter most: getting the right diagnosis, keeping treatment on track, and looking after your overall health.
