John Feenstra is a pulmonologist based in Chermside, QLD, Australia. He looks after people with lung and breathing problems, especially when the issue is more complex than a simple cold or cough. In many cases, the plan isn’t just about treating symptoms. It’s also about finding out what’s driving the problem and helping people understand what to expect next.
John’s work focuses on conditions like pulmonary hypertension, where the blood pressure in the lungs is higher than it should be. This can make everyday activities feel harder, and it can leave people feeling short of breath even with mild effort. He also works with people who have hypertension, since high blood pressure can affect the body in more than one way and may link in with other health concerns.
Breathing issues can come on slowly or suddenly, and sometimes they show up after a serious infection. John also helps with care related to COVID-19, including ongoing breathing trouble that can linger after the infection. Some people notice ongoing tiredness, tightness in the chest, or breathlessness when they didn’t have it before. Getting the right assessment early can make a big difference to how smoothly things settle.
At times, patients may need procedures as part of their care. John’s clinic includes work connected to angioplasty, which is a treatment used to help open up blocked or narrowed blood vessels. In the lung and heart area, getting the circulation right can be an important part of helping someone feel better and improving safety during recovery.
Because breathing problems can be stressful, John aims for clear communication and a steady, practical approach. He takes time to explain things in plain language, and he helps people plan next steps that make sense day to day. It’s often a back-and-forth process, with checks along the way to see if treatment is working.
John is based in Chermside, so local patients can access care without too much hassle. If you’re dealing with breathlessness, lung symptoms that aren’t going away, or health concerns linked to blood pressure and lung circulation, he can help sort through what’s going on and guide the next steps.
