What is Sleep Apnea?

Sleep apnea refers to the repeated cessation of breathing during sleep. In Hong Kong, an estimated ＊280,000 people—about 5% of the population—are affected by this condition.

The word “apnea” comes from the Greek word meaning “without breath”. Individuals with sleep apnea may stop breathing for 10 seconds to over a minute during sleep. In mild cases, this may happen around five times per hour; in severe cases, it can occur over 10 times per hour.

Due to inadequate oxygen supply, the brain and other organs may not receive enough oxygen, and some individuals may briefly wake up during sleep. Although these awakenings are not often remembered, sleep is still disrupted. Over time, this leads to sleep deprivation, excessive daytime sleepiness, and difficulty focusing. People who drive or operate heavy machinery may face increased risks of serious accidents due to fatigue.

Health Risks Linked to Sleep Apnea

More than just disrupted sleep, sleep apnea can lead to serious long-term health consequences. This is true for anyone affected, including those managing sleep apnea in Hong Kong.

Some of the most common effects include:

• Daytime drowsiness and reduced concentration
• Mood changes, irritability, or depression
• Increased risk of high blood pressure and heart disease
• Greater likelihood of type 2 diabetes
• Disrupted work performance and social life
• Higher chance of workplace or traffic accidents

3 Main Types of Sleep Apnea

Sleep apnea is not a one-size-fits-all condition. There are three main types, and understanding them can help guide the most suitable treatment approach. Identify the type of sleep apnea to receive the right care in Hong Kong from the start.

Obstructive Sleep Apnea

This is the most common type of sleep apnea. It occurs when the muscles in the throat relax excessively during sleep, causing the airway to narrow or close. Snoring is often a key symptom, and breathing interruptions may happen frequently throughout the night.

Central Sleep Apnea

Unlike obstructive types, central sleep apnea is caused by a failure of the brain to send proper signals to the muscles that control breathing. People with this type may experience pauses in breathing without noticeable physical blockage.

Mixed Sleep Apnea

Mixed sleep apnea is a combination of both obstructive and central types. It may begin as central sleep apnea and later develop characteristics of airway blockage. Diagnosis often requires more detailed testing and evaluation.

In-Home Testing for Sleep Apnea

An in-home sleep test offers a convenient way to monitor your breathing patterns overnight in a familiar setting. For individuals being evaluated for sleep apnea in Hong Kong, it provides an accessible and comfortable alternative to hospital-based sleep studies.

This test typically records airflow, oxygen levels, heart rate, and body movements to help assess the presence and severity of sleep-related breathing disorders. Early detection is key, and a home test can be the first step toward effective treatment.

How Can I Treat It?

Sleep apnea can affect your overall health, work performance, and even relationships. It is important to receive proper treatment to restore restful, uninterrupted sleep. The most effective and widely used therapy is the CPAP (Continuous Positive Airway Pressure) Machine.
