Obstructive sleep apnea

Definition

Obstructive sleep apnea (OSA) is a condition characterized by repeated episodes of partial or complete obstruction of the upper airway during sleep, leading to disrupted breathing. It is commonly associated with reduced oxygen levels in the blood and poor sleep quality, impacting overall health.

5 Must Know Facts For Your Next Test

1. OSA can exacerbate pulmonary conditions like chronic obstructive pulmonary disease (COPD) due to intermittent hypoxia.
2. Excess body weight is a significant risk factor for OSA and can worsen its severity.
3. Proper nutrition, including weight management and avoiding alcohol before bedtime, can help mitigate OSA symptoms.
4. Untreated OSA increases the risk of cardiovascular diseases such as hypertension and stroke.
5. Continuous Positive Airway Pressure (CPAP) therapy is a common treatment for OSA that helps keep airways open during sleep.
