Dizziness in Children: Common Causes, Symptoms and Treatment Options

Posted on by Prof. Dr. İbrahim Cansaran TANIDIR

Dizziness in children results from temporary inconsistencies in the systems that control the body’s balance center, momentary changes in blood pressure, metabolic factors, or the natural defense mechanisms of the autonomic nervous system in response to environmental triggers. Rapid bodily changes in growing children can sometimes challenge coordination between the blood vessels and the heart, causing short-term fluctuations in blood flow to the brain. This complaint may also occur due to inner ear disorders, anemia, fluid and electrolyte imbalances, or, in rare cases, abnormalities in the heart’s conduction pathways. Correctly identifying the underlying cause of the complaint is the first step toward detecting potential health problems early and safely supporting the child’s growth and development.

How Are Complaints of Dizziness in Children Medically Classified?

It is not always easy for a child to put the loss of balance or lightheadedness they experience into words. A child may describe this complex sensation simply as “I feel bad” or “I feel like I’m going to fall.” Therefore, certain basic classifications are used in clinical evaluations to understand what the child is experiencing. In cases of a true spinning sensation, the child describes feeling as though they or the objects around them are spinning like a ride at an amusement park. This condition usually results from a temporary problem in the balance center of the inner ear or the vestibular nerves. Middle ear infections or fluid imbalances in the inner ear may contribute to this condition.

Sometimes there is no spinning sensation, but the child feels an emptiness inside their head, a sense of lightness as though walking on air, or general lightheadedness. Rather than a physical illness, this condition may arise from intense stress, excessive anxiety, rapid breathing, or mild metabolic fluctuations. In another situation, the child has difficulty standing, sways from side to side while walking, and may drop objects they are holding. In this case, temporary or permanent problems involving coordination between the muscular and nervous systems become more prominent.

The group that requires the greatest attention and is closely associated with the cardiovascular system is the sensation of impending fainting. The child reports that their vision becomes dark, surrounding sounds seem muffled as though coming through a tunnel, and their knees feel weak. This sensation results from a momentary, borderline reduction in the amount of blood reaching the brain. Each of these different sensations points to a different system in the body and provides very important clues for identifying the source of the problem.

What Is the Main Cause of Dizziness and Fainting Sensations in Children?

Our brain is the organ that consumes the most energy and oxygen in our body and requires continuous, regular blood flow to function. Even an interruption lasting a few seconds in this blood flow can cause the brain to activate its protective mechanisms. The condition in which the body seemingly switches off its systems temporarily as a result of a short-term reduction in blood reaching the brain is medically called syncope and is commonly known as fainting. This condition occurs so frequently during childhood and particularly adolescence that nearly one in four young people experiences it at least once before reaching the age of eighteen.

Adolescence, when growth spurts are most intense, height increases rapidly, and hormones are constantly changing, is a period during which the body may sometimes struggle to regulate blood pressure adequately. While trying to adapt to these rapid changes, the body may experience momentary difficulty pumping blood upward against gravity toward the brain. Although a large proportion of these fainting episodes result from harmless autonomic reflexes, posture-related drops in blood pressure and problems originating directly from the heart may also be involved. The fundamental issue is whether the heart and blood vessels can respond quickly enough and appropriately to the circumstances at that moment.

Under What Circumstances Does Reflex-Related Dizziness Occur in Children?

A very large proportion of fainting episodes in childhood result from autonomic reflexes known as neurocardiogenic or vasovagal reflexes, which are generally benign. Our bodies contain a network of nerves that automatically regulates heart rate and blood vessel diameter independently of our conscious control. Sometimes this neural network produces an excessive and inappropriate response to an environmental or emotional stimulus. As a result of this incorrect signal, blood vessels suddenly dilate, the heart rate abruptly slows, and blood pressure rapidly falls, reducing blood flow to the brain.

Some everyday triggers that may activate this type of reflex include:

  • Standing motionless for long periods
  • Insufficient fluid intake
  • Poorly ventilated environments
  • Crowded places
  • Prolonged periods without eating
  • Sudden and severe pain
  • Extreme fear
  • Unexpected intense stress

When exposed to these triggers, the body does not immediately give in; it sends certain warning signals before fainting occurs. The child’s face suddenly becomes pale, cold sweating begins on their forehead, and they experience intense nausea. If these signs are recognized in time and the child immediately lies down on the ground and raises their legs, the reflex can be interrupted and fainting can most likely be prevented. Breath-holding spells seen during infancy, in which the child holds their breath while crying and turns bluish, are also a similar reflex response produced by the autonomic nervous system at an early age.

Why Do Children Experience Dizziness When Standing Up?

When a person suddenly stands up from a seated or lying position, a considerable amount of blood in the body tends to pool in the legs as a natural consequence of gravity. In a healthy functioning system, the body immediately detects this, slightly constricts the blood vessels in the legs, and makes the heart beat a little faster to redirect blood upward toward the brain. However, in some situations, the body cannot activate this defense mechanism quickly or strongly enough.

When this delay occurs, blood pressure suddenly drops as soon as the child stands up. Darkening of vision and lightheadedness result precisely from this momentary drop in blood pressure. These complaints become much more pronounced in children who do not drink enough water during the day because the volume of blood inside their vessels decreases. Another situation involves the heart responding excessively to this pooling of blood. The body sends a very strong adrenaline-like signal to draw blood from the legs upward, and the heart begins beating much faster than normal. In this condition, called Postural Orthostatic Tachycardia Syndrome (POTS), severe palpitations cause considerable discomfort to the child even if blood pressure does not decrease.

Common daily complaints in children with this condition include:

  • Severe palpitations
  • Chronic fatigue
  • Difficulty standing
  • Problems with mental concentration
  • Discomfort in the chest area
  • Frequently recurring headaches
  • Sleep pattern disturbances

Why Is Dizziness Caused by Heart Disease Dangerous in Children?

Although only a very small proportion of fainting episodes originate directly from the heart, this is the group that requires the most careful examination because of the risks involved. In heart-related problems, unlike harmless reflexes, the reason the brain is deprived of oxygen is a genuine insufficiency in the heart’s ability to pump blood. The heart may temporarily become unable to deliver the blood required by the body into circulation because of a mechanical obstruction in its structure or a malfunction in its electrical system.

Mechanical problems directly affect the heart’s structure and function. When the chambers or valves inside the heart do not function adequately, the increased demand for blood, particularly during physical activity, cannot be met. Some structural problems that require investigation include:

  • Narrowing of the heart valves
  • Thickening of the heart muscle
  • Enlargement of the heart chambers
  • Inflammation of the heart muscle
  • Coronary artery abnormalities

On the other hand, even if the heart’s structure appears completely normal, the problem may lie in its electrical conduction system. In these conditions, known as arrhythmias, the heart beats so rapidly that it contracts ineffectively before having enough time to fill with blood. Sometimes the heart’s natural pacemaker pauses momentarily, and the heartbeat stops for several seconds because the electrical current is interrupted. In both cases, blood flow to the brain is suddenly and sharply cut off, causing the child to collapse without experiencing any warning symptoms. Therefore, heart-related conditions require extremely careful investigation because they may pose a life-threatening risk.

Which Symptoms Are Considered “Red Flags” in Children with Dizziness?

During medical evaluations, certain symptoms provide very strong warnings that the complaint may indicate a condition too serious to be explained by a simple autonomic reflex. These warning signs are called “red flags,” and the presence of any one of them requires detailed cardiological investigations without delay.

The main warning signs to watch for include:

  • Fainting during sports (with exertion)
  • Sudden collapse without warning symptoms
  • Unexplained deaths at a young age in the family
  • Loss of consciousness while sitting
  • Loss of consciousness while lying down
  • Major injuries resulting from falls
  • Accompanying severe chest pain
  • Unexpected severe palpitations
  • Shortness of breath that increases with exertion
  • Bluish discoloration at rest

Loss of consciousness occurring while running, swimming, or participating in any sport is particularly critical. Under normal circumstances, the body increases blood pressure and heart rate during exertion to improve blood flow to the brain. However, if there is a heart-related narrowing or rhythm problem, the heart cannot tolerate the stress created by this exertion, and the system suddenly collapses. Similarly, if a child faints while sitting or lying in bed, this considerably increases the possibility of a primary problem involving heart rhythm or brain waves because the situation cannot be explained by gravity.

How Does the Cardiological Diagnostic Process Work for Dizziness in Children?

When a child is evaluated in a clinic, the account provided by both the child and their family is first listened to in great detail. The times of day when complaints occur, how long they last, what happened before the episode, and the sensations experienced by the child are recorded individually. The family’s medical history is also extremely important at this stage. A step-by-step testing process is then initiated to understand the overall condition of the heart.

Commonly used evaluation tools include:

  • Comprehensive physical examination and medical history
  • Surface electrocardiography (ECG)
  • Echocardiographic imaging
  • 24-hour Holter heart rhythm monitor
  • Exercise/Treadmill stress test
  • Tilt table test

The electrocardiogram (ECG) performed in the initial stage records the heart’s electrical activity at that moment on paper and reveals possible conduction blocks or additional electrical pathways. Echocardiography, which uses ultrasound waves, is then performed to examine the heart chambers, wall thickness, and condition of the valves. This procedure is completely painless and provides detailed information about the anatomical structure of the heart.

If the child’s complaints come and go intermittently throughout the day, a few seconds of ECG recording performed at the hospital will not be sufficient to detect the problem. In this situation, small adhesive electrodes are attached to the child’s chest, and a small recording device is fitted. This device, called a Holter monitor, continuously records the child’s heart rhythm for days while they continue their daily activities. For complaints occurring during exertion, the child walks on a treadmill and undergoes an exercise stress test. In cases of frequent fainting whose cause cannot be fully determined, special methods such as the tilt table test, in which the child lies on a secure table and their response to gravity is monitored, are used and greatly assist in establishing the diagnosis.

What Can Be Done at Home for Benign Dizziness in Children?

If all comprehensive examinations and assessments reveal that the problem is caused solely by a harmless autonomic reflex, this provides considerable reassurance to families. In such cases, intensive medication treatments that may burden the body are generally not used. The condition usually tends to subside on its own as the growth period is completed. Simple daily precautions help the autonomic nervous system remain more stable.

The main measures recommended at home and school include:

  • Increasing daily fluid intake
  • Adding some salt to meals
  • Limiting tea consumption
  • Avoiding coffee
  • Not consuming energy drinks
  • Avoiding prolonged periods without eating
  • Avoiding standing up suddenly
  • Avoiding hot baths
  • Avoiding poorly ventilated environments
  • Maintaining regular nighttime sleep

Water consumption is particularly critical. Maintaining an adequate volume of blood inside the vessels is the most natural way to prevent sudden drops in blood pressure. The child should be taught to lie down immediately on the ground and elevate their legs as soon as they notice their vision darkening or feel lightheaded. This movement allows blood pooled in the legs to return to the brain within seconds with the help of gravity. When fainting occurs, it is sufficient for those nearby to remain calm, safely position the child on their side, and elevate their legs. Interventions such as splashing water on the face or shaking the child should be avoided because they may cause more harm than good.

Which Treatments Are Used for Dizziness Caused by Serious Heart Problems in Children?

If cardiological examinations reveal that the complaints are directly caused by a problem in the heart’s electrical system or physical structure, more advanced treatments are planned to eliminate the risk and restore normal heart function. Thanks to the possibilities offered by medical technology, very positive outcomes are now anticipated in managing these types of problems.

Medical methods that may be preferred depending on the nature of the heart problem include:

  • Catheter ablation
  • Permanent pacemaker implantation
  • Implantable cardioverter-defibrillator placement
  • Balloon valve dilation
  • Corrective open surgeries

If a small abnormal electrical pathway or an additional conduction pathway causing unnecessary acceleration of the heart rate is detected inside the heart, catheter ablation is used to attempt to deactivate these areas with special waves. In cases where the heart’s natural rate becomes excessively slow or its conduction pathways are interrupted, permanent pacemakers are used. These small devices aim to ensure that the heart beats at the correct rate at all times.

For more life-threatening rhythm disorders, advanced devices capable of intervening automatically against the risk of cardiac arrest are implanted. When narrowing of the heart valves is detected, these stenoses are generally opened with the help of balloons using angiography-like methods without requiring surgery. In cases where structural problems are more complex, open surgical repair procedures may be planned.
