Name one major risk factor for developing sleep apnea.

Obesity is a significant risk factor for developing sleep apnea due to the way excess weight can impact the respiratory system. Increased body mass, especially around the neck, can lead to airway obstruction during sleep. This occurs because fatty tissues can constrict the airway passages, making it more difficult to breathe at night, which is a hallmark of sleep apnea.

Obesity is also associated with inflammation and hormonal changes that can further exacerbate the condition. While factors such as age, gender, and activity levels can play a role in sleep apnea development, obesity stands out as a modifiable risk factor that has a substantial impact on the severity and prevalence of sleep apnea. Addressing obesity through weight loss can significantly improve or even resolve symptoms of sleep apnea, highlighting its critical role in the disorder.
