How Can Sleep Apnea Be Recognized in Children?

Sleep apnea in children is a sleep disorder that occurs when breathing repeatedly decreases or stops for short periods during sleep. The most common type is obstructive sleep apnea. In this condition, the upper airway narrows or closes during sleep, making it difficult for the child to breathe comfortably.

Symptoms in children may differ from those seen in adults. While daytime sleepiness may be more noticeable in adults, children may show hyperactivity, restlessness, attention difficulties, reduced school performance, or behavioral changes. For this reason, sleep apnea in children should not always be evaluated only through snoring.

What Are the Symptoms of Sleep Apnea in Children?

Symptoms of sleep apnea in children may appear differently at night and during the day. Nighttime findings may be prominent in some children, while in others, the first changes noticed by families may be related to daytime behavior.

The severity of symptoms is not the same in every child. Mild symptoms may increase during temporary nasal congestion or an upper respiratory infection. However, if regular snoring, breathing pauses during sleep, and changes affecting daytime functioning are present, evaluation by a pediatrician is important.

Symptoms That May Be Seen at Night

Symptoms that occur while the child is sleeping are usually noticed by a parent or caregiver. Changes in breathing sounds, difficulty breathing, or restless sleep may draw attention.

Symptoms of sleep apnea that may be seen at night in children include:

• Loud snoring on many nights of the week
• Breathing stopping for short periods during sleep
• Sighing, grunting, or choking sounds after a pause in breathing
• Sleeping with the mouth open and breathing through the mouth
• Frequently changing position during sleep
• Unusual sleeping positions with the head tilted backward
• Noticeable breathing effort in the chest and abdomen
• Waking frequently throughout the night
• Heavy sweating
• Restless sleep
• Behaviors such as sleepwalking or talking during sleep
• Bedwetting that starts again after toilet training has been completed
• Dry mouth or headache in the morning

Not every child who snores has sleep apnea. Temporary snoring may occur particularly during colds or allergy periods. In contrast, snoring that is persistent, occurs together with breathing pauses, or is accompanied by noticeable breathing effort may require more detailed evaluation.

Symptoms That May Be Seen During the Day

Sleep apnea in children does not always present as daytime dozing. Poor-quality and frequently interrupted sleep may appear as hyperactivity, impulsivity, or irritability in some children.

Symptoms that may be noticed during the day include:

• Difficulty waking in the morning
• Waking unrefreshed and restless
• Fatigue during the day
• Excessive activity
• Impulsive behavior
• Irritability and mood changes
• Difficulty sustaining attention
• Forgetfulness
• Difficulty following lessons
• Reduced school performance
• Behavioral changes noticed by a teacher
• An increased need for daytime naps for the child’s age
• Poor appetite or slowed growth

These symptoms are not specific only to sleep apnea. Attention deficit, anxiety, insufficient sleep duration, iron deficiency, thyroid problems, and different health conditions may cause similar complaints. Therefore, behavioral changes should not be interpreted as sleep apnea on their own.

When Should Snoring in Children Be Taken Seriously?

Occasional mild snoring in children does not always indicate a serious health problem. Nasal congestion, allergies, colds, or sleeping position may cause temporary snoring.

However, evaluation is needed when snoring occurs several nights a week, has continued for a long time, or is accompanied by breathing pauses. Noticeable use of the chest and abdominal muscles to breathe during sleep may also be an important finding.

Snoring should not be ignored in the following situations:

• Snoring is regular and loud
• Breathing pauses are noticed during sleep
• The child makes choking sounds
• Chest retractions are seen during sleep
• Mouth breathing continues during the day
• The child consistently wakes tired in the morning
• There are changes in behavior, attention, or school performance
• Growth and weight gain are slower than expected

It may be helpful for parents to record the symptoms they notice during sleep. A short video showing the child’s head, chest, and breathing sounds may also help the physician understand the symptoms. However, a video recording does not replace a sleep test or medical evaluation.

What Causes Sleep Apnea in Children?

One of the most common causes of obstructive sleep apnea in children is enlarged tonsils and adenoids. Because these tissues are located in the upper airway, they may restrict airflow during sleep when they become enlarged.

However, the cause is not the same in every child. Nasal congestion, allergic conditions, excess weight, differences in jaw and facial structure, conditions that affect muscle tone, and certain genetic disorders may also increase the risk of sleep apnea.

Enlarged Tonsils and Adenoids

Tonsil and adenoid tissue may be more prominent during childhood than in adulthood. Enlargement of these tissues may make the airway more likely to narrow, particularly when the child is asleep and the throat muscles relax.

Large tonsils do not always mean that sleep apnea is present. Snoring, breathing pauses, mouth breathing, frequent infections, and daytime symptoms are considered together during the evaluation.

Nasal Congestion and Allergies

Allergic rhinitis, enlarged nasal tissue, or chronic nasal congestion may make it difficult for a child to breathe through the nose. The child may begin breathing through the mouth during sleep, and breathing sounds may increase.

Allergy-related complaints may change seasonally. However, if persistent mouth breathing continues even during periods without nasal congestion, evaluation by a pediatrician or an ear, nose, and throat specialist may be required.

Excess Weight

Excess weight may also increase the risk of obstructive sleep apnea in children. Fat tissue around the neck and upper airway may contribute to the airway narrowing more easily during sleep.

Sleep apnea is not seen only in children with excess weight. Children with a healthy body weight may also develop sleep apnea because of enlarged tonsils and adenoids or structural causes.

Jaw, Facial, and Airway Structure

A receding lower jaw, certain developmental differences in the facial bones, or a naturally narrow upper airway may affect airflow during sleep.

The risk may be higher in children with Down syndrome, certain neuromuscular diseases, and craniofacial differences. The evaluation of these children may be planned together with the relevant pediatric specialties and a sleep center.

Can Sleep Apnea Be Confused with Hyperactivity in Children?

A child who wakes frequently throughout the night because of sleep apnea may not get sufficient and restorative sleep. While adults may appear slower and sleepier when sleep deprived, children may behave in a more active, impatient, or impulsive manner.

For this reason, the daytime effects of sleep apnea may resemble symptoms of attention deficit and hyperactivity in some children. When a child’s attention problem is evaluated, information about sleep habits, snoring, mouth breathing, and nighttime breathing should also be obtained.

Sleep apnea and attention deficit hyperactivity disorder are not the same condition. Both conditions may also occur together in a child. Diagnosis should not be based only on behavioral observation; a comprehensive assessment should be performed by a pediatrician and the necessary specialties.

Can Sleep Apnea Affect Growth in Children?

Sleep is important for growth and development. Frequent sleep interruption caused by sleep apnea may negatively affect the child’s rest and daily functioning.

Some children with severe or long-standing sleep apnea may experience poor appetite, feeding difficulty, or slowed weight gain. Spending more energy on breathing throughout the night may also be one of the factors that can affect growth.

Slowed weight or height development does not mean sleep apnea on its own. Nutritional deficiencies, digestive system diseases, hormonal problems, and chronic illnesses may also affect growth. Evaluation by a pediatrician is required when a noticeable change in the growth curve is observed.

Can Sleep Apnea Affect School Performance in Children?

Repeated breathing disturbances during sleep may interrupt sleep even when the child is not aware of them. The child may spend enough time in bed but may not get high-quality and restorative sleep.

As a result, a shorter attention span, learning difficulties, forgetfulness, difficulty completing homework, and behavioral problems at school may occur. Changes noticed by the teacher may be an important clue for the family.

There are many causes of reduced school performance. Sleep apnea may be one of these causes, but it is not the only possibility. When there is a change in school performance together with sleep symptoms, information from both the healthcare and educational environments should be evaluated together.

Can Bedwetting Be a Sign of Sleep Apnea in Children?

Bedwetting that starts again in a child who has completed toilet training may be one of the symptoms that can occur with sleep apnea. Disruption of sleep structure and physiological changes occurring throughout the night may contribute to this condition.

However, bedwetting may also have different causes, such as urinary tract infection, constipation, diabetes, stress, sleep depth, and developmental factors. Therefore, sleep apnea cannot be evaluated through bedwetting alone.

If bedwetting is accompanied by snoring, mouth breathing, breathing pauses, or daytime behavioral changes, it is important to share this information with the child’s pediatrician.

How Is Sleep Apnea Diagnosed in Children?

Sleep apnea in children is not diagnosed only on the basis of snoring or parental observation. The evaluation is performed through the child’s medical history, sleep symptoms, physical examination, and, when required, a sleep assessment.

During the examination, the size of the tonsils, nasal openness, mouth and jaw structure, growth measurements, and accompanying health conditions may be reviewed. The family’s observations about nighttime symptoms also contribute to the evaluation.

Sleep Diary

The family may be asked to record the child’s sleeping and waking times, nighttime awakenings, frequency of snoring, and daytime behaviors.

A sleep diary helps show the pattern of symptoms but does not diagnose sleep apnea on its own. Breathing may need to be objectively evaluated during sleep for diagnosis.

Nighttime Video Recording

A short video taken by a parent may help show the child’s snoring, breathing effort, and sleeping position to the physician.

It may be helpful for the recording to show chest and abdominal movements as well as the child’s face. Nevertheless, a video recording does not provide the oxygen and breathing data measured by a sleep test.

Sleep Test

A comprehensive overnight sleep test is an important evaluation method in the diagnosis of sleep apnea in children. Brain waves, eye movements, muscle activity, breathing, oxygen levels, heart rate, and sleep stages may be recorded during sleep.

The findings are evaluated using criteria appropriate for the child’s age. Because the meaning and threshold values of breathing events in children differ from those in adults, the results should be interpreted by healthcare professionals experienced in pediatric sleep.

Is an At-Home Sleep Test Suitable for Children?

An at-home sleep test is a method that may be used to evaluate obstructive sleep apnea in adults under certain conditions. In children, sleep structure, respiratory criteria, and the causes of sleep apnea differ from those in adults.

For this reason, the decision to use an at-home sleep test for a child should not be made routinely or automatically. The child’s age, symptoms, tonsil and adenoid structure, accompanying conditions, and the parameters the test can record should be evaluated. In some children, comprehensive polysomnography performed in a hospital or sleep center may be more appropriate.

Even if a limited respiratory recording performed at home gives a normal result, sleep apnea may not be completely ruled out when strong symptoms continue. In such a case, a pediatrician or sleep specialist may recommend a more comprehensive test.

Simple home breathing monitors used for babies are not the same as sleep tests intended for diagnosis. Consumer devices or smartwatch measurements should not be used to diagnose or rule out sleep apnea in children.

How Is Sleep Apnea Treated in Children?

Treatment is planned according to the cause and severity of sleep apnea, the child’s age, and accompanying health conditions. The same approach may not be suitable for every child.

If enlarged tonsils and adenoids are prominent, an ear, nose, and throat evaluation may be performed. Appropriate medical treatments may be considered for allergic nasal congestion, sustainable weight management for excess weight, and positive airway pressure devices for some children.

Approaches that may be used during treatment include:

• Evaluation of the tonsils and adenoids
• Management of allergies and nasal congestion
• Monitoring healthy growth and weight
• Planning positive airway pressure treatment in suitable children
• Evaluation of problems related to jaw and facial structure
• Follow-up of accompanying conditions
• Reassessment of symptoms after treatment
• A follow-up sleep test when required

A reduction in the child’s snoring does not by itself show that sleep apnea has completely resolved. Follow-up after treatment is important, particularly when risk factors continue.

Which Symptoms Require Emergency Evaluation?

Symptoms of sleep apnea generally require planned health assessment. However, online consultation or a routine appointment should not be awaited for certain breathing symptoms.

Emergency medical services should be contacted in the following situations:

• The child has noticeable difficulty breathing while awake
• Bluish discoloration of the lips, face, or nails
• Prolonged or repeated significant breathing pauses
• A change in the level of consciousness
• The child cannot be awakened or is unusually unresponsive
• Noticeable chest retractions and rapid breathing
• Suspected foreign body aspiration
• A whistling, wheezing, or high-pitched sound during breathing

Remote assessment may not be sufficient for these symptoms. The child should be taken directly to a healthcare institution or emergency medical services should be contacted.

This content is intended for general information. For the diagnosis and treatment of sleep apnea in children, assessment should be performed by a pediatrician, pediatric pulmonologist, ear, nose, and throat specialist, or a healthcare professional experienced in sleep health.
