About of Bastien Lechat

Bastien Lechat is a sleep medicine doctor based in Bedford Park, Adelaide, SA. He helps people when sleep is getting in the way of everyday life. Sleep can be tricky for lots of reasons, and in many cases the problem is not “just stress” or “just bad habits”. It can be linked to breathing, body signals, routines, and even how your brain and body reset each night.


In his practice, Bastien focuses on common sleep and health issues such as obstructive sleep apnoea, insomnia, and excessive daytime sleepiness. Sleep apnoea is when breathing keeps pausing during sleep, which can leave you feeling tired even after a full night. Hypertension can also be part of the picture, because poor sleep and breathing problems can affect blood pressure over time. For some people, regular sleep timing goes off track too, and an irregular sleep-wake pattern can make it hard to fall asleep and stay asleep at the right times.


Bastien also looks after restless legs syndrome, a condition that can bring uncomfortable urges to move the legs, especially when you’re trying to rest. He can help with drowsiness and that heavy, “can’t switch off” feeling that shows up in the daytime. At times, people describe unusual sensations, including issues like vasoconstriction, and they may also feel affected during the day because their sleep quality is not great. There are also reports in some cases of cerebral hypoxia related to sleep breathing issues, which is another reason careful assessment matters.


Not everyone fits the same pattern, and sleep problems can overlap. That’s why Bastien works in a practical way, aiming to understand what’s happening for you and what might be driving it. He takes the time to sort through symptoms such as waking up unrefreshed, feeling sleepy behind the wheel, tossing and turning, or struggling to keep a steady routine. He also supports people dealing with drowsiness and low alertness, because that can affect work, family life, and safety.


As for training and learning, the focus is on staying current with sleep medicine care and evidence-based treatment options. Even when the cause is complex, the goal stays simple: better sleep, better breathing, and more stable energy during the day. You can expect a calm, clear approach, with care guided by your symptoms and your day-to-day situation. There’s no one-size-fits-all fix, but the right plan can make a real difference.


Bastien treats adult patients who are trying to get back control of their sleep. If you’re dealing with ongoing tiredness, sleep disruption, or symptoms that keep coming back, he can help you work out what to do next.
