Philip De Chazal is a Sleep Medicine doctor based in Sydney, NSW, Australia. His work is centred on helping people when sleep problems start to affect day-to-day life.
Sleep issues can show up in different ways. Some people struggle to fall asleep or stay asleep. Others find they are still tired even after a full night in bed. At times, the problem is linked to breathing during sleep.
Philip looks after patients with obstructive sleep apnoea (OSA), where breathing can repeatedly pause or slow down during sleep. He also works with central sleep apnoea, which is a different type, but can still leave someone feeling worn out and unwell during the day. Symptoms like drowsiness and excessive daytime sleepiness are often front and centre in these cases.
In some situations, sleep-related breathing issues can be connected to lower oxygen levels overnight. This can lead to concerns like cerebral hypoxia. It’s also a reminder that sleep isn’t just about rest, it can affect the body’s health in more serious ways.
There are also times when sleep problems overlap with other medical concerns. For example, anaemia can contribute to tiredness and poor energy. Philip focuses on understanding what’s going on, so the right steps can be taken for sleep and for the other health factors that might be playing a role.
Sleep medicine isn’t only about adults. Philip also works with premature infants, where early health and breathing support can matter a lot. Necrotizing enterocolitis is another condition that can come up in the care of premature babies, and sleep and breathing concerns may be part of the wider picture in hospital settings.
There aren’t one-size-fits-all answers with sleep. Over time, the plan usually involves getting the details right, matching the treatment to the type of sleep problem, and keeping an eye on how symptoms change. If you’re dealing with insomnia, ongoing drowsiness, or suspected sleep apnoea, Philip’s approach is practical and based on the specific issues affecting you.
