Stephen M. Riordan is a gastroenterologist based in Sydney, NSW, Australia. He looks after people with health issues that affect the gut and liver, from stomach bugs to long-term bowel and oesophagus conditions.
In day to day care, he sees patients for things like bacterial gastroenteritis, campylobacter infection, and viral gastroenteritis. These can cause symptoms such as tummy pain, diarrhoea, nausea, and dehydration. At times, he also helps people who have problems higher up, including Barrett oesophagus, which can develop after long-term reflux.
For liver and bile duct concerns, his work includes cholangitis and cholestasis. He also treats cirrhosis, which can happen when the liver has been damaged over time. This kind of care often involves careful monitoring and making sure symptoms are managed as well as possible.
Stephen also treats inflammatory bowel conditions. This includes colitis and Crohn’s disease. These conditions can be hard to live with, with flares that come and go. In many cases, the goal is to settle symptoms, support steady control, and help people understand what might trigger problems for them.
Stephen’s training is focused on gastroenterology, so patients can expect a practical approach to gut health. He works through the details in a calm way, using the information from symptoms and tests to plan the next steps.
Research and clinical trials information is not listed here, so the focus stays on clinic care and ongoing treatment planning for gastro-related conditions.
