Siobhain A. Mulrennan is a pulmonologist based in Crawley, Western Australia, working from M581, 35 Stirling Hwy, Crawley WA 6009.
Respiratory health can be complex, and it often affects day to day life in a big way. Dr Mulrennan looks after adults and children with ongoing lung problems, as well as conditions that can flare up and settle back down.
Her care focuses on the lungs and airways, including asthma and ongoing breathing issues such as bronchitis and stridor. She also helps patients with long-term conditions where there is ongoing damage or inflammation in the airways, like bronchiectasis. Over time, these issues can lead to mucus build-up, repeated infections, and trouble clearing the airways, so follow-up and a steady plan matter.
She also manages people with more specific lung and immune-related conditions. This can include sarcoidosis, which may affect the lungs and other parts of the body. At times, lung symptoms can be linked to allergies and immune reactions, such as allergic bronchopulmonary aspergillosis. Cystic fibrosis is another area of focus, where breathing issues often come with added challenges like thick secretions and recurring chest infections.
Some patients she sees have breathing problems that relate to other health changes too. For example, gastroesophageal reflux disease (GERD) can affect the airways, and exocrine pancreatic insufficiency can create nutritional challenges that also impact overall health. There are also conditions where the airway may become swollen or inflamed, including tracheitis.
Dr Mulrennan’s work includes looking at more urgent and complex situations as well, such as saddle pulmonary embolism and risks around lung damage. She can also be involved in care for people exposed to dust and particles, including silicosis. And where needed, care may extend to heart-related causes that can affect blood flow through the lungs, such as tricuspid atresia.
Care is usually built around clear, practical plans. Treatment can involve breathing tests, monitoring symptoms, and coordinating support so patients know what to watch for and when to seek help. Evidence-based care is important, and in some cases research and clinical trials may be considered as part of the wider treatment picture.
