Frequent question: Why does obesity cause obstructive sleep apnea?

In obese people, the narrowing of upper respiratory muscles occurs because of the accumulation of fatty tissues. The obstruction in breathing due to the narrowing of the upper airway causes a marked increase in intrathoracic pressure and triggers apnea and hypoxia [26].

Why does obesity cause sleep apnea?

Excess body weight contributes to sleep apnea by causing increased pressure on upper airways, leading to collapse and decreased neuromuscular control from the fatty deposits. These fatty deposits contribute to decreased lung volume and make it more difficult to breathe (Young, Skatrud & Peppard, 2013).

Why is obesity a risk factor for obstructive sleep apnea?

Obesity may worsen OSA because of fat deposition in tissues of the upper airway, resulting in a smaller lumen and increased collapsibility, and in the thorax, reducing chest compliance and functional residual capacity.

Does obesity increase the risk of Obstructive Sleep Apnea Syndrome?

How does obesity cause sleep problems?

Can skinny people have sleep apnea?

Medical conditions that are associated with obesity, such as hypothyroidism and polycystic ovary syndrome, also can cause obstructive sleep apnea. However, not everyone with obstructive sleep apnea is overweight and vice versa. Thin people can develop the disorder, too.

Will losing weight cure my sleep apnea?

Weight loss of just 10-15% can reduce the severity of OSA by 50% in moderately obese patients. Unfortunately, while weight loss can provide meaningful improvements in OSA, it usually does not lead to a complete cure, and many sleep apnea patients need additional therapies.

What BMI puts you at risk for sleep apnea?

More than half of people with obstructive sleep apnea are either overweight (body mass index, or BMI, of 25-29.9) or obese (BMI of 30.0 or above). A 10% weight gain raises your risk of OSA by six times, though the effect goes down after age 60. Another marker of obesity is the size of your neck.

Does sleep apnea ever go away?

Can Sleep Apnea Go Away? For the most part, sleep apnea is a chronic condition that does not go away. Anatomy tends to remain fixed, especially after adolescence has ended. Therefore, children with sleep apnea may retain hope for the condition being successfully and definitively treated.

Does sleep apnea cause brain damage?

OSA is a chronic disease that involves repetitive pauses in breathing during sleep. These breathing pauses can prevent your body from supplying enough oxygen to the brain. In severe cases this lack of oxygen can lead to brain damage. Signs of this damage include memory problems, difficulty concentrating, and moodiness.

What are the warning signs of sleep apnea?
