Fainting in children - why do they occur?

High temperatures and dehydration often provoke fainting in children. Their appearance, however, may also indicate changes that are taking place in the body. Should we be afraid of them?

1. Types of syncope

Fainting is a sudden, transient, short-term and spontaneous loss of consciousness. It is caused by a reduction in brain perfusion, i.e. temporary hypoxia. Consciousness returns a few minutes after its occurrence.

Often the term syncope is called a temporary imbalance. This is a mistake because a person who faints cannot keep their body upright.

The incomplete loss of consciousness is a pre-syncope state - the child's muscle tone is then reduced, but contact is not lost.

You can talk about fainting when a person falls limp. It is often associated with head injuries. The autoregulation of the circulatory system is most often disturbed then - it is then a reflex syncope and it is not life-threatening.

Cardiogenic syncope is much more serious. It can be a symptom of a serious illness or even a factor leading to death. This is because these fainting are triggered by: arrhythmias, obstructed outflow of blood from the ventricles and other diseases related to the heart and coronary vessels.

The last type of syncope is orthostatic syncope, which occurs immediately after the body is upright. Patients with this type of loss of consciousness experience an increased heart rate.

2. Fainting in children and adolescents

In children and adolescents, fainting occurs most often as a result of a sudden drop in blood pressure or a slow heart rate. This may be due to stress or unexpected events that the children are a part of. Fainting can also be the result of severe coughing attacks in asthma.

Statistically, they constitute 1-3 percent. from all emergencies that occur in the youngest patients. Even 15 percent. children between the ages of 8 and 18 have passed out at least once in their lives.

Fainting symptoms are visual disturbances (spots in front of the eyes), dizziness, nausea, sweating or feeling hot. Children often show a pale face. Some people experience mild seizures after a fall. You should then protect the child's tongue against chewing.

3. Fainting in infants

Babies also faint. In this case, there are attacks of cyanotic apnea: the baby cries for a long time, then becomes breathless, and pale apnea: the baby screams, turns pale and loses consciousness.

In 85 percent in children, these symptoms disappear spontaneously by the age of 5. Some doctors believe that fainting in children may be related to a lack of iron in the blood.

4. Find the cause of the loss of consciousness

Fainting in children and adolescents, although common, in most cases is not dangerous. They most often pass spontaneously and do not affect health in adulthood. However, it is worth checking the cause of their occurrence. Check-ups at a pediatrician will certainly not hurt.
