John Croese is a Gastroenterologist based in Cairns, QLD, Australia. He looks after people with bowel and gut issues, from ongoing stomach problems to things that need closer checks.
In this part of Queensland, some gut problems can be linked to infections you might not see as often elsewhere. John helps manage conditions such as hookworm infection, whipworm infection, angiostrongyliasis, and other types of helminthiasis. He also treats tropical sprue and can support patients dealing with malabsorption, where the body struggles to take in food and nutrients properly.
John also sees people for gut conditions closer to home. This can include coeliac disease, eosinophilic enteropathy, and other causes of long-lasting tummy symptoms. At times, people come in after viral gastroenteritis too, especially when symptoms hang around and they need a plan to get back on track.
If something needs a closer look inside, John offers endoscopy and colonoscopy. These tests help find what’s going on in the gut, and they can guide next steps. For some patients, that means checking for colorectal cancer, while for others it’s about understanding bleeding, bowel habit changes, or ongoing pain that hasn’t settled.
He also treats conditions like creeping eruption, which can be confusing and stressful when it shows up on the skin. Getting the right diagnosis matters, and John works to connect the skin symptoms with what’s happening in the body.
John’s care is practical and steady. Gastro symptoms can take a big toll on your day to day life, so he focuses on clear explanations and sensible next steps. Over time, many people find it helps to have someone who understands both the gut side of things and the way infections and nutrition issues can overlap.
Details like research work and clinical trials aren’t listed here, but John’s approach is still based on good medical practice and keeping decisions grounded in what helps most for each person’s situation.
