Simon Ghaly is a Gastroenterologist based in Sydney. He works at St Vincent's Hospital Sydney and St Vincent's Clinical School, in NSW. This is a busy hospital setting, so patients often come in with issues that need clear answers and steady care.
Simon looks after people with bowel and gut conditions, especially ongoing bowel inflammation. This can include ulcerative colitis and Crohn’s disease, as well as related problems like proctocolitis. He also supports patients who have colitis from infections, including viral gastroenteritis, where symptoms can hit hard and make it hard to keep fluids up.
At times, care needs to cover complications that come along with gut illness. That may involve malnutrition and vitamin D deficiency, and issues like iron deficiency anaemia. Simon also helps patients who have had bowel surgery and now live with stomas, such as colostomy or ileostomy, focusing on day to day comfort and getting the right plan for ongoing health.
While his main work is gastroenterology, the hospital environment means he also deals with the wider picture when other parts of the body are affected. Some patients may come with concerns that involve bleeding in the bowel area, tissue necrosis, or other health problems that need careful follow up. In a smaller number of cases, he may be involved when people have heart-related inflammation, like pericarditis, especially when it connects to their overall illness and symptoms.
Over time, Simon’s work has centred on listening, explaining what’s going on in plain language, and helping patients understand their options. Gastro symptoms can be stressful and tiring, so having a calm plan matters. In many cases, that means sorting out tests, managing flare-ups, and adjusting treatment when things change.
Because he’s based at a clinical school, he’s also part of a teaching hospital. That often brings a practical, learning-focused approach to care, with doctors and teams working together across disciplines. It’s not just about one appointment. It’s about making sure the whole pathway makes sense for the person in front of him.
If you’re looking for care for bowel inflammation, gut infection, nutritional problems, or stoma support, Simon Ghaly is there to help guide you through the next steps.
