Marian P. Kumarasinghe is a Gastroenterologist based in Nedlands, WA, working out of Hospital Avenue, Nedlands, WA 6009, Australia.
Marian looks after people with stomach, bowel, and gut related health issues. This can include long-term problems like colitis, and things that show up during checks such as colorectal polyps. At times, care may also involve issues higher up in the gut, like Barrett’s oesophagus and ongoing reflux-related irritation.
When symptoms need a closer look, endoscopy is often part of the plan. Endoscopy helps doctors see what’s going on and guide next steps. Marian also provides care for cancers of the digestive system, including cancers of the oesophagus, gastro-oesophageal junction, stomach, and the pancreas. In many cases, treatment plans are made with other health professionals so patients get coordinated support.
Some patients are managing more complex or rare conditions. Marian’s practice includes care for people with bowel and cancer risk syndromes, like Cowden syndrome, Turcot syndrome, and Bannayan-Riley-Ruvalcaba syndrome. There are also situations where conditions such as toxic megacolon need careful attention, along with other inflammatory and infection-related gut problems like viral gastroenteritis.
Over time, the work can involve diagnosing problems early, keeping an eye on changes, and helping people understand results in plain language. It can be a stressful space to be in, so the focus is usually on clear explanations and steady, practical next steps.
Education and work experience details aren’t listed on this page, but the service includes endoscopy and ongoing gastroenterology care for a wide range of gut conditions. If you’d like the exact training background or specific experience for a certain condition, it’s best to contact the clinic for the most up-to-date info.
Research and clinical trials are not listed here, so there may be none mentioned publicly, or they may be handled through the wider hospital and specialist networks. When relevant, Marian can discuss options and referrals as part of care planning.
For anyone in the Nedlands area needing help with gut health—whether it’s ongoing inflammation, findings from scopes, or concerns about cancer—Marian aims to make the process feel less confusing and more manageable.
