Brett G. Toelle is a Pulmonologist based in Sydney, NSW, Australia.
He looks after people who have breathing problems and conditions that affect the airways. That can include asthma, and asthma in children. Asthma can change day to day, and it often needs a plan that fits real life—work, school, sleep, and sports.
Brett also cares for patients with chronic obstructive pulmonary disease (COPD). COPD can make it hard to move around, climb stairs, or even do everyday tasks without getting out of breath. In many cases, treatment is about easing symptoms and helping people breathe more comfortably day to day.
Allergic rhinitis is another common issue he treats. It can cause a blocked or runny nose, sneezing, and that annoying post-nasal drip feeling. When allergies flare up, they can also affect how well someone sleeps and how steady their breathing feels.
Some visits involve more urgent airway problems too. Brett sees patients with anaphylaxis, where quick action matters. He also assesses stridor, which is that noisy breathing you may hear, especially when a child is unwell. Over time, the goal is to work out what is causing the symptoms and what steps to take next.
He sees people across the spectrum of respiratory illness, from common colds to infections like pertussis. Even “everyday” illnesses can hit harder if someone already has asthma or COPD, so it’s not just about treating the current sickness—it’s also about keeping future flare-ups in check.
Breathing can be affected by more than just lungs. Brett also treats obesity, which can contribute to breathlessness and make it harder to stay active. In many cases, small changes can make a real difference, and he focuses on practical, doable steps.
Day to day, his work is about listening to what’s happening, checking symptoms, and helping patients and families understand their options. At times, care includes making sure plans are clear for when symptoms get worse, and when it’s time to seek more urgent help.
Overall, Brett is part of the respiratory care journey for people in Sydney who want straightforward guidance and steady support for long-term airway conditions, plus help when breathing symptoms turn up unexpectedly.
