About OSA
Adequate sleep is one the most important aspects for a healthy life. Several medical conditions may affect sleep. Sleep breathing disorders are one of them and may occur at any age. Usually, if observed in kids can be the result of obstruction of the airway due to enlarged adenoids and/or malocclusion (‘bad bite’). Adequate treatment at early age can correct the problem and avoid serious problems that can occur later in life.
The most common breathing disorder in adults is OSA (Obstructive Sleep Apnea). In this case breathing is interrupted during sleep due to obstruction of the airway. This can develop because either the muscles relax too much during sleep compromising the airway, or the airway is blocked by the tongue and soft palate collapse. The severity of OSA is measured by how many times the person’s breathing is interrupted during sleep. In severe cases a person can stop breathing up 60 or more times per hour.
These disruptions impair your ability to reach the desired deep, restful phases of sleep, and you will probably feel sleepy during your waking hours.
As a result of interrupted breathing there can be a drop in the amount of oxygen in the blood stream. This can create other problems, such as cardiovascular diseases.
Signs and symptoms of Obstructive Sleep Apnea (OSA) include:
- Excessive daytime sleepiness
- Loud snoring
- Observed episodes of breathing cessation during sleep
- Abrupt awakenings accompanied by gasping or choking
- Awakening with a dry mouth or sore throat
- Morning headache
- Difficulty concentrating during the day
- Experiencing mood changes, such as depression or irritability
- High blood pressure
Risk factors
Anyone can develop obstructive sleep apnea. However, certain factors put you at increased risk:
- Excess weight: Around half the people with obstructive sleep apnea are overweight. Fat deposits around the upper airway may obstruct breathing.
- Narrowed airway: You may inherit naturally narrow airways. Or, your tonsils or adenoids may become enlarged, which can block your airway.
- High blood pressure (hypertension): Obstructive sleep apnea is relatively common in people with hypertension.
- Chronic nasal congestion: Obstructive sleep apnea occurs twice as often in those who have consistent nasal congestion at night, regardless of the cause. This may be due to narrowed airways.
- Smoking: People who smoke are more likely to have obstructive sleep apnea.
- Diabetes: Obstructive sleep apnea may be more common in people with diabetes.
- Gender: In general, men are twice as likely as women to have obstructive sleep apnea.
- A family history of sleep apnea: If you have family members with obstructive sleep apnea, you may be at increased risk.
- Asthma: Recent research has found an association between asthma and the risk of obstructive sleep apnea.
Treatment
Screening for OSA
There are different questionnaires available for a fast screening and to check if you are at risk for OSA (Obstructive Sleep Apnea)
