Natalia Rodriguez-Castano is a gastroenterologist based in Sydney, NSW (2052). She works with people who have gut and bowel symptoms that just won’t settle, or conditions that need ongoing check-ups to keep things under control.
In day-to-day care, Natalia looks after issues like indigestion and gastroesophageal reflux disease (GERD). She also helps manage long-term problems such as Barrett’s oesophagus, where the lining of the food pipe needs monitoring over time. At times, she may be involved in helping with investigations and ongoing care for stomach cancer concerns, depending on the results and the overall plan with the treating team.
She also treats inflammatory bowel conditions, including colitis, Crohn’s disease, and ulcerative colitis. When someone is dealing with flare-ups, abdominal pain, diarrhoea, bleeding, or weight loss, her focus is on making a clear plan and keeping follow-ups steady. The aim is simple: help symptoms ease, reduce the risk of complications, and support patients with treatment decisions that fit their situation.
Infections are another part of her work. Natalia treats Helicobacter pylori infection, as well as other gut infections such as campylobacter infection and viral gastroenteritis. For some patients, getting the diagnosis right early can make a big difference to how quickly symptoms improve.
She also has experience dealing with conditions like hemorrhagic proctocolitis. And while some infections and severe illness are handled with a broader team, Natalia can be part of the care for complex cases where the gut plays a key role, including neonatal sepsis in the right clinical setting.
Education-wise, Natalia’s medical training is built around digestive health and the way the gastro system works. She keeps up with updated guidelines and practical changes in care as new information becomes available, so her approach stays current without making things overly complicated.
Clinical trials can matter for some people, especially when a condition is tough to manage or keeps coming back. Natalia can talk through trial options where they fit, and explain what to expect in plain language, based on what’s suitable for that specific situation.
If you’re in Sydney and looking for a gastroenterologist to help you sort out ongoing gut symptoms or a long-term gut condition, Natalia is there to guide the next steps calmly and clearly.
