When Your Child Has Obstructive Sleep Apnea (OSA)
Obstructive sleep apnea is a fairly common problem in children. However, it often goes undiagnosed. This is partly because symptoms can be different than they are in adults. OSA occurs when the airway becomes blocked during sleep. When this happens, the brain tells the body to wake up just enough to open the airway and allow breathing again. This can happen many times throughout the night, even though your child doesn't remember it. The quality of sleep can be very poor.
What are the causes of OSA?In children, enlarged tonsils and adenoids (structures in the back of the throat) are the most common cause of sleep apnea. When muscle tone is relaxed during sleep, these throat tissues collapse and cause complete or partial blockage of airflow. Being overweight can also make sleep apnea more likely, but extra weight is a less common cause in children than it is in adults. In some children, the shape of the face, jaw, or tongue leads to a blocked airway during sleep. Your child's doctor can tell you more about what's causing your child's sleep apnea.
What are the signs and symptoms of OSA?
- Snoring, gasping, or snorting, along with periods of not breathing
- Breathing through the mouth, at night and during the day
- Restless sleep, or sleeping in unusual positions
- Nighttime sweating
- Difficulty waking up in the morning
- Daytime sleepiness or irritability
- Headaches in the morning
- Hyperactivity and trouble paying attention
- Learning problems
How is OSA diagnosed?
The doctor may refer you to a doctor with special training in sleep disorders. Or, you may be referred to an ear, nose, and throat doctor (otolaryngologist). To diagnose sleep apnea, the doctor asks about your child's health history and sleep habits. He or she examines and weighs your child. An overnight sleep study (polysomnography) may also be suggested.
What is an overnight sleep study?
To confirm a diagnosis, your child will need an overnight sleep study. This is done in a sleep lab, which may be located in a hospital or special clinic. Bring pajamas for your child, as well as something that will help your child feel more comfortable, such as a stuffed animal. You will be able to sleep in a bed near your child. You can help prepare your child by describing in advance as much as you can: Tell your child who will be present and where you will be. Answer your child's questions and use pictures to help explain the procedure, if that's helpful. During the sleep study, electrodes and sensors are attached to your child's body. They measure many things, including:
- Activity of your child's brain and muscles
- Electrical activity of your child's heart
- Oxygen content in your child's blood
- Movement of the chest and abdomen
- Airflow through the mouth and nose
- Number of partial or complete airway blockages during the night
How is OSA treated?
Treatment depends on your child's age, health, and medical history, as well as any underlying conditions. Your child's doctor may suggest the following:
- Treatment to remove tonsils (tonsillectomy) and adenoids (adenoidectomy)
- Continuous positive airway pressure (CPAP), a nose or face mask that delivers steady air pressure during sleep
- Losing excess weight
What are the long-term concerns?
Left untreated, obstructive sleep apnea can cause growth, learning, or behavior problems. It can even cause heart problems. But treatment can help prevent these problems, lessen their severity, or make them go away.
