Guy B. Marks is a pulmonologist in Glebe, NSW. He works out of 431 Glebe Point Rd, Glebe, in the inner west of Sydney.
As a lung specialist, Guy looks after people with breathing problems and long-term chest conditions. This can include asthma, especially when it is hard to keep under control, and asthma in children. At times, he also helps with eosinophilic asthma, where the body’s inflammation plays a big role.
COPD is another common area of care. That includes ongoing lung issues like chronic cough, wheeze and shortness of breath. People with bronchitis, bronchiectasis, or repeated chest infections may also come in for help, including when symptoms keep coming back.
Guy also treats people after infections and during recovery. Conditions such as pneumonia, COVID-19 and the long tail some people feel after respiratory illness can be part of his work. For others, the focus is on spotting and managing more serious causes of breathing symptoms, including pulmonary tuberculosis when appropriate.
Breathing at night matters too. Obstructive sleep apnoea, obesity hypoventilation syndrome (OHS), and general breathing problems linked with obesity can affect sleep, energy and overall health. He also looks at respiratory acidosis in cases where breathing is not doing its job well.
Allergies can sit underneath a lot of breathing issues. Guy may also help when there is allergic rhinitis and other related conditions that affect the nose, eyes and airways. Sometimes skin conditions like atopic dermatitis show up alongside breathing symptoms, so it helps to view the bigger picture.
There are also less common, but important, problems that can need a careful lung-focused approach. That includes stridor, pertussis (whooping cough), and work-related lung disease such as silicosis. People with concerns about atherosclerosis may also be assessed for any breathing-related links.
Over time, good care is about more than just quick fixes. In many cases, it means getting the diagnosis right, working out what triggers the symptoms, and then building a plan that fits day-to-day life. Guy’s goal is to help people breathe easier and feel more steady, whether the issue is sudden, ongoing, or comes back in bursts.
