Obstructive Sleep Apnoea (OSA): Causes, Symptoms and Treatment

Focus Keyword: Obstructive Sleep Apnoea (OSA)

Sleep is essential for maintaining good physical and mental health. However, some people struggle to get restful sleep because of breathing problems during the night. Obstructive Sleep Apnoea (OSA) is one of the most common sleep-related breathing disorders. It occurs when the muscles in the throat relax during sleep and partially or completely block the airway, causing breathing to stop and restart repeatedly.

If left untreated, Obstructive Sleep Apnoea (OSA) can affect sleep quality, daytime energy, concentration and overall health. Understanding its symptoms, causes and treatment options can help people seek appropriate medical care.

What Is Obstructive Sleep Apnoea (OSA)?

Obstructive Sleep Apnoea (OSA) is a condition in which the upper airway becomes blocked repeatedly while a person is sleeping. When the airway is blocked, airflow to the lungs decreases or stops temporarily. The brain may briefly wake the person to restore normal breathing, although these awakenings are often so short that the person does not remember them.

These repeated interruptions can occur many times during the night. As a result, the person may not get enough deep, restorative sleep even if they spend several hours in bed.

Common Symptoms of Obstructive Sleep Apnoea (OSA)

The symptoms of Obstructive Sleep Apnoea (OSA) can occur during both sleep and waking hours. Some common signs include:

• Loud and persistent snoring

• Pauses in breathing during sleep

• Gasping or choking sounds at night

• Excessive daytime sleepiness

• Morning headaches

• Dry mouth or sore throat after waking

• Difficulty concentrating

• Irritability or mood changes

• Restless sleep

• Frequent nighttime awakening

A person may not always notice these symptoms themselves. In many cases, a partner or family member may first observe loud snoring or pauses in breathing.

What Causes Obstructive Sleep Apnoea?

Several factors can contribute to Obstructive Sleep Apnoea (OSA). The condition commonly develops when the muscles supporting the throat and tongue relax excessively during sleep.

Factors that may increase the risk include:

1. Excess Body Weight

Being overweight can increase fatty tissue around the upper airway, making it easier for the airway to become narrowed or blocked during sleep.

2. Enlarged Tonsils or Other Airway Structures

Enlarged tonsils, adenoids or certain anatomical characteristics can reduce the space available for airflow.

3. Sleeping Position

For some people, sleeping on the back can make airway obstruction more likely because the tongue and soft tissues may move backward.

4. Age

The risk of sleep apnoea may increase with age because muscle tone and other physical changes can affect the airway.

5. Family History and Anatomy

A naturally narrow airway, certain facial structures or a family history of sleep apnoea may increase the likelihood of developing the condition.

How Is Obstructive Sleep Apnoea Diagnosed?

If symptoms suggest Obstructive Sleep Apnoea (OSA), a healthcare professional may recommend a sleep evaluation. Diagnosis commonly involves assessing symptoms, medical history and sleep patterns.

A sleep study, also known as polysomnography, may be recommended. Depending on the individual's circumstances, testing may be performed in a sleep centre or with a home sleep-apnoea test.

The test can monitor factors such as breathing patterns, oxygen levels, heart rate and other sleep-related measurements. The results help healthcare professionals determine whether sleep apnoea is present and how severe it may be.

Treatment Options for Obstructive Sleep Apnoea (OSA)

Treatment for Obstructive Sleep Apnoea (OSA) depends on the severity of the condition and the individual's overall health.

Continuous Positive Airway Pressure (CPAP)

CPAP therapy is a commonly used treatment for moderate to severe obstructive sleep apnoea. The device delivers a continuous flow of air through a mask, helping keep the airway open during sleep.

Lifestyle Changes

For some people, lifestyle changes may improve symptoms. These may include maintaining a healthy weight, exercising regularly, avoiding alcohol close to bedtime and following healthy sleep habits.

Oral Appliances

Certain specially designed oral appliances can help reposition the jaw or tongue to keep the airway open during sleep. These may be suitable for some people with mild to moderate sleep apnoea.

Positional Therapy

If symptoms are worse when sleeping on the back, positional therapy may help encourage sleeping on the side.

Surgery

In selected cases, surgery may be considered when structural problems contribute significantly to airway obstruction or when other treatments are not suitable or effective.

Why Should Obstructive Sleep Apnoea Be Treated?

Untreated Obstructive Sleep Apnoea (OSA) can interfere with normal sleep and daytime functioning. Repeated breathing interruptions may lead to excessive daytime sleepiness and difficulty concentrating.

Over time, untreated sleep apnoea may also be associated with serious health problems, including high blood pressure and cardiovascular complications. It can also increase the risk of accidents related to excessive sleepiness.

Early evaluation and appropriate treatment can help improve sleep quality and daytime wellbeing.

When Should You See a Doctor?

You should consider speaking with a healthcare professional if you regularly experience loud snoring, breathing pauses during sleep, nighttime choking or excessive daytime sleepiness.

It is especially important to seek medical advice if a partner or family member notices that you repeatedly stop breathing during sleep.

Do not ignore persistent symptoms simply because you are able to sleep for several hours. The quality of sleep and uninterrupted breathing are also important for good health.

Conclusion

Obstructive Sleep Apnoea (OSA) is a common sleep-related breathing condition that can significantly affect sleep quality and daily life. Recognizing symptoms such as loud snoring, breathing pauses, morning headaches and daytime sleepiness can encourage early evaluation.
