Bhajan P. Singh is a pulmonologist based in Perth, WA, Australia. He looks after people who have breathing and sleep problems, especially the things that can make everyday life feel hard.
Many patients see him because of obstructive sleep apnea. This is a common issue where breathing pauses during sleep, which can lead to poor rest. It can also show up as loud snoring, restless sleep, and waking up feeling unrefreshed. In many cases, it also links in with drowsiness and excessive daytime sleepiness, where a person feels tired even after a full night in bed.
Sleep can be affected in other ways too. Bhajan P. Singh works with people who have central sleep apnea, along with insomnia that makes it tough to fall asleep or stay asleep. At times, these sleep issues can be made worse by other health concerns, including obesity hypoventilation syndrome (OHS). When breathing is not stable overnight, it can affect how the body handles oxygen, and people may feel drained, foggy, or short of breath.
He also helps manage lung conditions. For example, people with chronic obstructive pulmonary disease (COPD) may need ongoing care to support breathing and reduce flare-ups. Others may be dealing with cystic fibrosis, where the lungs can get affected over time. Pleural effusion is another condition that can come up, where fluid builds around the lungs and can make breathing feel uncomfortable.
Sometimes the reason for a visit is less obvious. Bhajan P. Singh may be involved when there are signs of low oxygen in the body, such as cerebral hypoxia, or when breathing problems connect with other health changes like hypertension. He also deals with symptoms and issues that can make people feel unwell or unsettled, including periods of drowsiness and ongoing breathing discomfort.
While sleep and lung care are different, they often overlap. The aim is usually the same: help people get steadier breathing, sleep better, and feel more like themselves during the day. Over time, treatment plans can be adjusted based on how symptoms change and how the person is doing at home.
Based in Perth, Bhajan P. Singh provides care for a wide range of breathing and sleep-related problems, from obstructive and central sleep apnea through to COPD and pleural effusion. If you’re dealing with tiredness, poor sleep, or breathing symptoms that just won’t settle, a visit can be a good starting point.
