What Is Obstructive Sleep Apnoea and Why Does It Matter?

Sleep apnoea is a sleep disorder where breathing repeatedly stops and starts during sleep. These pauses in breathing can last several seconds and may occur many times an hour. Each time breathing stops, oxygen levels drop, and the brain briefly wakes the body to restart breathing.

Most people are not aware that these awakenings are happening, but they prevent deep, restorative sleep and place strain on the body.

What Causes Obstructive Sleep Apnoea?

Sleep apnoea is most often caused by the airway becoming narrowed or blocked during sleep. This can happen when the throat muscles relax too much, reducing airflow and limiting the amount of oxygen reaching the lungs. In response, the brain briefly wakes the body to restore normal breathing—often without you even noticing.

Risk Factors For Obstructive Sleep Apnoea (OSA)

You may be at higher risk of obstructive sleep apnoea if you have any of these factors:

A naturally narrow airway

A naturally narrow airway

A thicker neck, smaller jaw, enlarged tonsils, or nasal blockage can all reduce airflow during sleep.

### Lifestyle triggers

Lifestyle triggers

Alcohol, smoking, and some sedatives can relax throat muscles and make snoring and breathing pauses worse.

### Being overweight

Being overweight

Overweight can increase pressure around the throat, making the airway more likely to narrow or collapse at night.

### Age and gender

Age and gender

Sleep apnoea is more common in men, and the risk tends to increase with age.

Severity is measured using the Apnoea-Hypopnoea Index (AHI) — the number of breathing interruptions per hour of sleep. Mild OSA is classified as 5–14 events per hour, moderate as 15–29, and severe as 30 or more. Your AHI score shapes your treatment pathway: CPAP is typically recommended for moderate to severe OSA, while milder cases may respond to lifestyle changes or a mandibular device.

How is sleep apnoea diagnosed

How Is Sleep Apnoea Diagnosed?

Accurate diagnosis is the first step. At LIPS Healthcare, our clinic near Battersea Power Station is led by Dr Amit Patel, a specialist respiratory consultant with extensive experience in diagnosing and managing sleep apnoea. Our team provides thorough assessments to confirm sleep apnoea and build a personalised treatment plan around your results. As a private clinic, we offer rapid access to specialist assessment — typically within days — without the delays of an NHS referral pathway.

Sleep apnoea is usually diagnosed with a sleep study, which measures breathing patterns overnight and helps identify the type and severity of sleep apnoea.
