Deirdre A. Collins is a gastroenterologist based in Perth, WA, Australia. Gastroenterology is the branch of medicine that looks after the digestive system, including the gut and how food is broken down and absorbed. In day-to-day care, that can mean working through gut symptoms that come and go, and also sorting out what’s going on when infections or bowel problems cause more serious illness.
Her practice focuses on conditions linked to diarrhoea and gut infections. This includes problems like pseudomembranous colitis and toxic megacolon, which can become urgent and need close attention. She also treats ongoing or severe diarrhoea, and looks at causes such as amebiasis and infections related to water or travel, including cholera. Small bowel bacterial overgrowth (often shortened to SIBO) is another issue that can affect bloating, gut discomfort and bowel habits.
At times, gut symptoms can sit alongside infections in other parts of the body. The profile lists conditions such as strep throat and viral gastroenteritis, plus yaws. When symptoms overlap like this, the work is often about getting the right diagnosis and making a clear plan for treatment, so people can feel better and avoid complications.
On the profile, details like exact years of experience, specific education, research interests, and hospital affiliations are not listed. If those details are important for you, they can usually be confirmed through the clinic directly. Clinical trials are also not specified in the information provided, so it’s best to ask if there are any current studies that may be relevant to your situation.
Overall, the goal of care is practical and supportive. Gut problems can make life hard, especially when symptoms are strong or keep coming back. Over time, good treatment often comes down to listening to what’s happening, checking the key causes, and staying on top of red flags—particularly with conditions like toxic megacolon, where timing matters.
