Mark Lust is a gastroenterologist based at St Vincent's Hospital Melbourne, in Fitzroy, VIC. He works with people who have ongoing gut and liver health concerns, from days when things feel off to problems that keep coming back over time.
As a gastroenterologist, Mark looks after conditions that affect the digestive tract and nearby organs. This can include inflammatory bowel conditions like ulcerative colitis and Crohn’s disease. He also helps manage colitis and related problems, including haemorrhagic proctocolitis, where symptoms can be distressing and sometimes hard to ignore.
GI issues aren’t always long term. At times, people come in after an infection, such as viral gastroenteritis, where the focus is on getting things under control, watching hydration, and making sure recovery is on track. Mark also deals with liver and bile-related conditions, including hepatitis and intrahepatic cholestasis of pregnancy, which can make pregnancy feel more stressful than it should be.
When symptoms show up, it can be tough to know what’s normal and what needs checks. Mark takes a practical approach to help people make sense of what’s happening, and what the next steps might be. In many cases, that means careful assessment, discussing symptoms clearly, and working out a plan that fits the person in front of him.
He understands that gut and liver problems can affect day-to-day life, not just health charts. People might be dealing with pain, bleeding, changes in bowel habits, fatigue, or skin and gut symptoms that seem to come and go. Mark focuses on calm, steady care, and aims to reduce worry by explaining things in simple terms.
Mark’s training in gastroenterology supports his work across both outpatient and hospital settings at St Vincent's Hospital Melbourne. Over time, he has built a way of working that balances medical care with the human side of illness, especially when conditions need longer follow-up.
Education and training can’t fix everything on its own, but they do set the base for safe, thoughtful care. Mark also stays up to date with current clinical guidance so treatment decisions are grounded in what’s most helpful for patients right now.
If you’re dealing with a gut or liver issue and you want support that’s clear, steady, and grounded, Mark Lust at St Vincent's Hospital Melbourne is there to help work through it.
