Over 50% of patients diagnosed with Obstructive Sleep Apnoea (OSA) are classified as obese. This high percentage highlights the strong correlation between obesity and sleep apnoea, where excess fat in the neck and abdomen can obstruct the airway during sleep. This relationship underscores the importance of addressing weight management as a key component in the treatment and prevention of OSA.

Understanding Obstructive Sleep Apnoea (OSA)
Obstructive Sleep Apnoea (OSA) is a serious sleep disorder characterized by repeated interruptions in breathing during sleep. One of the significant risk factors associated with OSA is obesity.
Obesity and OSA Statistics
- Studies indicate that over 50% of patients diagnosed with OSA are classified as obese.
- Obesity is defined as having a Body Mass Index (BMI) of 30 or higher, which contributes to excess fat around the neck and throat, leading to airway obstruction during sleep.
Mechanism of OSA in Obese Patients
- In obese individuals, increased fatty tissue in the neck can compress the airway during sleep.
- This compression results in decreased airflow, causing the characteristic apneas (pauses in breathing) and hypopneas (shallow breathing) associated with OSA.
Impact of Obesity on Severity
- The severity of OSA often correlates with the degree of obesity.
- Higher BMI values are linked to more severe forms of sleep apnea, leading to greater health risks such as cardiovascular disease, diabetes, and hypertension.
Conclusion
- The prevalence of obesity in OSA patients emphasizes the importance of weight management as a potential treatment strategy.
- Addressing obesity can lead to significant improvements in sleep quality and overall health for those suffering from OSA.
In summary, the correct answer is indeed over 50%, highlighting the strong association between obesity and obstructive sleep apnoea.
