David R. Hillman is a pulmonologist based at 35 Stirling Highway, Crawley, WA 6009, Australia. His work centres on breathing health, especially problems that show up when people are asleep, when they’re resting, or when their body is struggling to get enough oxygen.
In many cases, patients come in with obstructive sleep apnoea or central sleep apnoea. He also looks after people with excessive daytime sleepiness, loud snoring that can’t be ignored, and ongoing tiredness that doesn’t match the amount of sleep. At times, the breathing issues can link with other health problems, like obesity or obesity hypoventilation syndrome (OHS).
Sleep and breathing don’t just affect how rested someone feels. They can also affect alertness, mood, and daily functioning. Dr Hillman supports people who are dealing with insomnia, drowsiness, or restless legs syndrome. He also helps when symptoms can be more complex, such as cerebral hypoxia, and when there are other related concerns like swallowing difficulty and reflux symptoms from gastroesophageal reflux disease (GERD).
Sometimes the reason for the appointment is a specific symptom that keeps coming back. That can include cramps and muscle twitching (cramp-fasciculation syndrome), or ongoing issues around sensation and awareness that may need careful assessment, including agnosia and adult syndrome. He also manages situations where breathing patterns can be linked to longer-term neuro and genetic conditions, such as Potocki-Lupski syndrome and Smith-Magenis syndrome.
Day-to-day care may also involve procedures like endoscopy, depending on what’s going on. The aim is usually pretty simple: to understand what’s driving the symptoms and to help people get safer, more comfortable breathing at night and better energy during the day.
