Warning Signs for Sleep Apnoea

Sleep apnoea a potentially serious sleep disorder often goes undiagnosed due to its subtle warning signs. Recognizing these signs is crucial for timely intervention and prevention of associated health risks. In this comprehensive guide, we delve into the warning signs of sleep apnoea shedding light on its symptoms risk factors, and the importance of seeking professional help.

What is Sleep Apnoea?

Before delving into its warning signs let’s understand what sleep apnoea is. Sleep apnoea is a disorder characterized by pauses in breathing during sleep. These pauses or apnoeas can occur multiple times throughout the night disrupting the sleep cycle and leading to a host of health issues.

 Types of Sleep Apnoea

  • Obstructive Sleep Apnoea (OSA): This is the most common form of sleep apnoea occurring when the muscles at the back of the throat relax excessively causing the airway to narrow or close.
  • Central Sleep Apnoea: Unlike OSA central sleep apnoea is less common and occurs when the brain fails to send signals to the muscles responsible for controlling breathing.
  • Complex Sleep Apnoea Syndrome: Also known as treatment-emergent central sleep apnoea this type is a combination of obstructive and central sleep apnoea.

Loud and Persistent Snoring

One of the hallmark symptoms of sleep apnoea is loud and persistent snoring. While occasional snoring is common, especially among individuals with allergies or nasal congestion chronic and disruptive snoring may indicate an underlying issue such as sleep apnoea.

Pauses in Breathing

Witnessed apnoeas where breathing stops for brief periods during sleep are significant warning signs for sleep apnoea. Bed partners or family members may observe these pauses often accompanied by gasping or choking sounds as breathing resumes.

Excessive Daytime Sleepiness

Experiencing excessive daytime sleepiness regardless of the amount of sleep obtained is a common symptom of sleep apnoea. This persistent fatigue can interfere with daily activities impair concentration and increase the risk of accidents.

Morning Headaches

Waking up with a headache, especially in the morning can be indicative of sleep apnoea. Repeated interruptions in breathing during sleep can lead to oxygen deprivation and subsequent headaches upon waking.

Difficulty Concentrating and Memory Issues

Sleep apnoea can impair cognitive function leading to difficulties concentrating memory lapses and poor decision-making. If you find yourself struggling to focus or retain information it’s essential to consider the possibility of sleep apnoea as a contributing factor.

Mood Changes and Irritability

Chronic sleep deprivation due to untreated sleep apnoea can significantly impact mood leading to irritability mood swings and even depression. Addressing the underlying sleep disorder is crucial for improving overall emotional well-being.

Frequent Nighttime Urination

Individuals with sleep apnoea may experience nocturia a condition characterized by frequent nighttime urination. The disrupted sleep patterns associated with sleep apnoea can affect the body’s regulation of fluids leading to increased urine production during the night.

Dry Mouth or Sore Throat Upon Waking

Waking up with a dry mouth or sore throat can be indicative of breathing through the mouth due to obstructed airflow during sleep. This can occur in individuals with sleep apnea as they struggle to maintain an open airway.

High Blood Pressure

Sleep apnea is often associated with hypertension or high blood pressure. Repeated episodes of interrupted breathing can lead to changes in blood oxygen levels and increased strain on the cardiovascular system contributing to elevated blood pressure.

Risk Factors for Sleep Apnoea

While anyone can develop sleep apnoea certain factors may increase the risk of developing this sleep disorder. Understanding these risk factors can help identify individuals who may be at higher risk and benefit from screening and early intervention.


Excess weight particularly around the neck can increase the risk of airway obstruction during sleep making obesity a significant risk factor for sleep apnoea.

Age and Gender

Sleep apnoea is more common in older adults, particularly men. However women especially those who are postmenopausal are also at increased risk.

Family History

A family history of sleep apnoea or other sleep disorders can predispose individuals to the condition suggesting a genetic component.

Smoking and Alcohol Consumption

Smoking and excessive alcohol consumption can relax the muscles of the throat and interfere with normal breathing patterns during sleep increasing the risk of sleep apnoea.

Medical Conditions

Certain medical conditions such as nasal congestion allergies asthma and hormonal disorders can contribute to airway obstruction and increase the risk of sleep apnoea.

Seeking Professional Help

If you or a loved one experiences any of the warning signs mentioned above it’s crucial to seek professional help promptly. A healthcare provider typically a sleep specialist or pulmonologist can conduct a thorough evaluation which may include a sleep study to diagnose sleep apnoea and recommend appropriate treatment options.

 Treatment Options

  • Continuous Positive Airway Pressure (CPAP): CPAP therapy involves wearing a mask over the nose or mouth during sleep which delivers a continuous flow of air to keep the airway open.
  • Oral Appliances: These devices are designed to reposition the jaw and tongue to prevent airway obstruction during sleep.
  • Lifestyle Modifications: Weight loss smoking cessation and reducing alcohol consumption can help alleviate symptoms of sleep apnoea.
  • Surgery: In severe cases or when other treatments fail surgical procedures may be recommended to remove or reduce excess tissue blocking the airway.
