Unveiling the Sleep Thief: Exploring the Top 10 Causes of Sleep Apnoea

Sleep apnoea, a sleep disorder characterised by interrupted breathing during sleep, can significantly impact an individual’s health and well-being. Understanding the causes behind this condition is crucial for effective prevention and management. In this blog post, we will delve into the various factors contributing to sleep apnoea, exploring how gender, age, weight, physical attributes, lifestyle choices, and medical conditions can influence its onset.

  1. Gender:
  • Men are more susceptible to sleep apnoea than women.
  • After menopause, the frequency of sleep apnoea in women increases, highlighting the role of hormonal changes. The intricate dance between hormones and sleep architecture provides a nuanced understanding of why women face an increased risk after this pivotal life stage.
  1. Age:
  • Sleep apnoea can affect individuals of any age, but its prevalence rises with age.
  • Muscle tone alterations and the cumulative impact of aging on the respiratory system contribute to the heightened susceptibility observed in older individuals.
  1. Weight:
  • Obesity is a significant risk factor for sleep apnoea.
  • The excessive accumulation of adipose tissue, especially around the neck, imposes a mechanical burden on the airways, increasing the likelihood of obstructive events during sleep.
  1. Physical Attributes:
  • Certain physical attributes can elevate the risk of sleep apnoea.
  • Individuals with a small upper airway, a receding jaw, a long soft palate, a high tongue position, a deviated septum, or enlarged tonsils and adenoids face an augmented risk due to anatomical predispositions.
  1. Smoking:
  • Smokers face a triple threat – the addictive habit itself, the associated inflammation, and fluid retention in the upper airway. Unraveling the impact of smoking on sleep apnoea highlights the intricate relationship between lifestyle choices and respiratory health.
  1. Alcohol, Sedatives, or Tranquilizers:
  • These substances induce muscle relaxation in the throat, exacerbating the condition and providing insights into the delicate balance between relaxation and airway stability
  • Understanding the impact of these substances is crucial for those at risk.
  1. Neck Circumference:
  • Individuals with thicker necks may have narrower airways, increasing the likelihood of sleep apnoea.
  • A neck circumference greater than 17 inches /  43.2 cm in men or 16 inches / 40.6 cm in women is associated with a higher risk.
  1. Nasal Congestion:
  • Breathing difficulties through the nose, whether caused by anatomical issues or allergies, form a significant contributor to obstructive sleep apnoea.
  1. Medical Conditions:
  • The tapestry of medical conditions contributing to sleep apnoea encompasses heart failure, hypertension, diabetes, Parkinson’s disease, polycystic ovary syndrome, hormonal disorders, strokes, and chronic lung diseases.
  • Unraveling this complex web of health conditions illuminates the diverse paths leading to sleep apnoea.
  1. Family History:
  • Having family members with sleep apnoea may increase an individual’s susceptibility to the condition.
  • Genetic factors play a role in predisposing certain individuals to sleep apnoea.

Sleep apnoea is a complex disorder with multifaceted causes. Recognising the interconnectedness of factors such as gender, age, weight, lifestyle choices, and genetic predispositions is crucial for both prevention and effective management. By addressing these contributing factors, individuals can take proactive steps to improve their sleep quality and overall well-being.
