Andrew D. Hayen is a pulmonologist based in North Sydney, working from 73 Miller Street, North Sydney, NSW 2060, Australia.
He helps people who have ongoing breathing problems, as well as those who need support when symptoms suddenly get worse. This includes conditions like interstitial lung disease, pulmonary fibrosis and idiopathic pulmonary fibrosis. At times, he also looks after people with acute interstitial pneumonia, where breathing can change quickly and needs close care.
Asthma is another big part of his day-to-day work. He also treats people dealing with other health issues that can affect how well the lungs and heart cope, such as flu and asthma flare-ups, plus problems like hypertension and coronary heart disease. In many cases, breathing symptoms can overlap with other conditions, so care often needs to be thought about as a whole picture, not just one diagnosis.
Alongside lung-focused problems, he also provides care for a range of common and serious medical issues listed in his practice. These can include gastroesophageal reflux disease (GERD), urinary tract infections (including in children), glaucoma, hepatitis and urinary infections. People with obesity in children, newborn jaundice, and infections like pertussis can also seek help. Some patients come in after events like cardiac arrest, while others need ongoing management for long-term problems such as chronic kidney disease or osteoporosis.
Over time, his approach is about staying calm, explaining things in plain language, and making sure the next steps are clear. When tests and results come in, he works with patients to understand what they mean, and what treatment options may help most. This is especially important with lung conditions that can be slow to change, or that can shift more quickly.
Andrew’s medical training includes specialist respiratory care, supported by real-world hospital-based experience. He also keeps up with current medical research that helps guide how lung disease is managed, even though no specific research projects are detailed in the information provided.
Clinical trials: no specific trial involvement is listed here. If a trial might be an option, that would usually be discussed case by case, based on the patient’s health and eligibility.
