Duncan S. Mortimer is a pulmonologist based in Melbourne, working from 18 Innovation Walk, Melbourne, VIC 3800, Australia. His day-to-day work centres on the lungs and breathing, but it also reaches into areas that can affect sleep, tiredness, and day-to-day thinking.
Many people who see him have sleep and breathing problems linked to body weight. This can include Obstructive Sleep Apnoea (OSA) and Obesity Hypoventilation Syndrome (OHS). These conditions can make nights feel restless, and they can leave people feeling worn out in the daytime. In many cases, getting the breathing issue under control can make a big difference to how someone feels and how they function.
Along with sleep and breathing, his practice also looks after concerns like obesity and issues that show up after a concussion or Traumatic Brain Injury (TBI). Some people also come in with memory loss or ongoing trouble with focus after a head injury. At times, breathing and sleep problems can sit alongside these changes, so it helps to look at the full picture rather than one single symptom.
The way care is handled is usually steady and practical. Appointments focus on listening first, then sorting out what might be driving the symptoms. Breathing and sleep problems can be easy to brush off, even when they are affecting sleep quality, energy, or mood. Duncan’s approach is to keep things clear and grounded, and to make sure people understand what is happening and what the next steps are.
As a pulmonologist, he is used to working with long-term conditions that may need ongoing check-ins. That might mean making sense of how symptoms change over time, or reviewing how treatment is going. For head injury concerns, he can also help connect the breathing and sleep side of things, which can matter for recovery and overall wellbeing.
Clinical trials and research details aren’t something that are commonly shared in the information available here, so the focus stays on regular, real-world care. If you’re dealing with sleep apnoea, OHS, obesity-related breathing issues, or you’re trying to recover after concussion or a TBI with memory problems in the mix, Duncan Mortimer is one of the clinicians in Melbourne who can help you get started.
