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.
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.
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
Difficulty waking up in the morning
Daytime sleepiness or irritability
Headaches in the morning
Hyperactivity and trouble paying attention
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.
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
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
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.
