Simon R. Knowles is a Gastroenterologist based in Melbourne, VIC, Australia. He works with people who have ongoing tummy and gut problems, as well as some issues that affect what the body can absorb and how the bowel works day to day.
In clinics across Melbourne, he looks after patients with conditions like Crohn’s disease, colitis and ulcerative colitis. He also helps people manage irritable bowel syndrome (IBS), chronic constipation, and long-term gut discomfort that can be hard to explain to others. At times, symptoms like bloating, bowel changes, pain, and trouble going to the toilet can come and go, and that’s where having a consistent plan matters.
Some people see him for celiac disease, especially when food choices and day-to-day symptoms affect energy and wellbeing. Others come in with malabsorption concerns, heavy metal poisoning, or digestive issues such as gastroparesis and ongoing indigestion. He takes a practical approach, focusing on how symptoms are showing up and what might be causing them, rather than rushing into labels.
He also supports patients with bowel incontinence and bowel management needs. This can be a sensitive topic, so appointments are usually kept calm and straightforward. For patients who have stomas, like colostomy or ileostomy, his care can include guidance around daily living, monitoring, and handling changes when they happen. Over time, he helps people feel more confident about routines, diet, and when to get help.
Simon has experience caring for a broad mix of digestive and related health concerns. His work is grounded in real-life situations, from long-running gut conditions to times when infections or sudden flare-ups cause things to shift quickly. He also looks after people dealing with viral gastroenteritis and other serious stomach and gut illness, including COVID-19, where digestive symptoms may be part of a larger picture.
On the education side, his training is in gastroenterology and digestive health. Details about degrees, research, and any clinical trial involvement aren’t listed here, but the day-to-day focus stays on safe, sensible care that fits with what patients are dealing with at home.
