How does obesity relate to sleep apnea?

• A. Obesity decreases airway resistance
• B. Obesity has no relation to sleep apnea
• C. Obesity can lead to airway obstruction during sleep
• D. Obesity prevents sleep disordered breathing

Answer: (C)

Obesity is a significant risk factor for sleep apnea primarily because it can lead to airway obstruction during sleep. Excess body weight, particularly around the neck and throat, can result in increased soft tissue that may collapse and obstruct the upper airway when a person lies down. This obstruction can disrupt normal breathing patterns and lead to episodes of apnea, where breathing temporarily stops, contributing to sleep-disordered breathing. The physiological effects of obesity, such as increased fat deposition in the neck area, can diminish the size of the airway, making it more prone to collapse during sleep. Additionally, obesity can influence the muscle tone and stability of the upper airway, increasing the likelihood of obstructive sleep apnea. Understanding this relationship underscores the importance of addressing obesity as a potential means to manage or reduce the severity of sleep apnea.
