A fainting child tumbling to the ground is a very upsetting moment for any parent, and a scary one for the child. The truth is, fainting episodes, or syncope (sin-ko-pea), is a fairly common occurrence in children and teens and–in most cases–harmless.
Fifteen percent of children will experience at least one fainting episode by the time they reach the age of 18. In younger children, an episode may occur when a child is crying or overly emotional. Teens may feel dizzy and faint when first getting out of bed in the morning, or after sitting for long periods of time. Girls are five times more likely to faint than boys. While it usually not serious, if your child faints it should not be ignored; there could be a more serious underlying cause.
Syncope, which is the medical term for fainting, happens when there is a sudden drop in blood pressure, reducing blood flow through the body and the amount of oxygen delivered to the brain. As soon as the body becomes horizontal, lying on the ground, the blood pressure returns to normal and carries oxygen back to the brain. As a result, in most cases, the child quickly recovers.
Most of the time, fainting is not a sign of a critical medical condition. There are several common causes of fainting which may cause a temporary drop in blood pressure, including:
Fainting can also be a symptom of a more serious medical condition. Children with heart or vascular disorders that restrict the flow of blood to the brain may experience syncope:
Some other serious medical conditions that might cause fainting may be:
Most kids who faint have symptoms just beforehand. These may include:
Preventing a fainting spell
If your child is prone to fainting spells, there are some things you can do to help them head off an episode.
First, know the symptoms. Some people feel dizzy immediately before they faint. They may also notice changes in vision (such as tunnel vision), a faster heartbeat, sweating and nausea. Someone who is about to faint may even throw up. If your child experiences any of these symptoms, he or she can try the following:
In the majority of cases, syncope will not be serious. However, you should still make an appointment with your child's pediatrician to rule out any causes that could put your child's life at risk. During your visit your pediatrician will take a detailed history of the event and symptoms associated with the fainting episode. He or she will also perform a careful examination, checking blood pressure and your child's heart rate lying down and standing up. This is usually all that is required. However, if your pediatrician feels there is concern, you will be referred to a pediatric heart specialist for further evaluation. With state-of-the-art testing and diagnostics, the specialists at Cook Children's Heart Center can diagnose your child's condition and work with you and your pediatrician to determine the best course of treatment for your child's particular condition.
