Viraj C. Kariyawasam is a Gastroenterologist based in Hospital Rd, Sydney, NSW 2139. He looks after people with gut health problems, especially conditions that affect the bowel and the lining of the digestive tract. If you’ve been dealing with ongoing stomach or bowel issues, it helps to have someone who can think it through step by step.
In his clinic, Viraj works with patients who may have inflammatory bowel conditions like ulcerative colitis, Crohn’s disease, and related issues such as colitis and hemorrhagic proctocolitis. He also helps people who have had viral gastroenteritis, and those with longer-term nutrition problems linked to the gut, including malnutrition and vitamin B12 deficiency (and B12 deficiency anaemia). At times, bowel health can get complicated, so the goal is steady care and clear next steps.
He also performs and organises checks that give a better picture of what’s happening inside. This can include colonoscopy and endoscopy. These tests can be important when symptoms don’t settle, or when doctors need to confirm what’s going on before choosing the right treatment path.
Over time, he’s learned that gut symptoms can affect everyday life in a big way. People can feel worried, run down, or unsure what caused their flare-ups. In many cases, it comes down to getting the diagnosis right, watching symptoms closely, and supporting nutrition and recovery where it’s needed.
When it comes to experience, he focuses on practical digestive care and common investigations used in gastroenterology. If you’d like details about training and past work history, it’s best to confirm what’s available through the clinic.
For research and new treatments, the information listed here is general. There’s no specific research project named on this page, but he keeps up with current approaches to care for gut conditions and nutrition-related problems.
