Syncope
Syncope is the medical word for fainting. It happens when less blood reaches the brain for a short time, causing a child to pass out.
What Is Syncope?
If your child has fainted, or passed out, their doctor or health care provider may call it syncope. Syncope happens when a person briefly loses consciousness and then wakes up again. Fainting is common in children and teens. Most children who faint don’t have a serious health problem.
What Causes Syncope?
Fainting can happen for many reasons. Common causes include:
- Not drinking enough fluids (dehydration)
- Not eating enough
- Standing for a long time
- Certain health problems
- Being too hot
- Stress, anxiety, or fear
- Being tired
- Pain
What Are the Signs and Symptoms of Syncope?
Before fainting, your child may have:
- Dizziness
- Light-headedness
- Visual blackout
- Paleness
- Sweating
- Nausea
- Feeling of warmth
- Tingling in fingers
- Racing heartbeat
If your child faints or feels dizzy often, their doctor or health care provider may recommend treatment, including medicines.
What Do I Do if My Child Faints?
If your child faints:
- Let them stay on the ground until they’re fully awake.
- Loosen any tight clothing.
- Offer small sips of water when your child is awake.
How Do You Prevent Syncope?
- Sitting and standing
- If your child feels dizzy or light-headed, have them sit or lie down right away.
- Encourage your child to stand up slowly after sitting or lying down.
- Squeezing the leg and thigh muscles while standing may help prevent fainting.
- Food and drink
- The best liquid for your child to drink is water. Ask your child’s doctor if certain drinks with vitamins and electrolytes are okay for your child to have.
- Ask your child’s doctor how much liquid your child should drink each day. Encourage your child to drink that much during the day.
- Your child’s body needs more fluids during hot weather and physical activity.
- Avoid drinks with caffeine and a lot of sugar, like soft drinks or soda.
- Your child’s doctor may recommend drinking more fluids and increasing sodium in their diet.
- Activities
- Take breaks during exercise and other activities.
- Avoid standing in one place for long periods of time. If standing for a long time can’t be avoided, shift weight from one foot to the other or move the legs often.
- Avoid hot or stuffy places when possible. Open windows, use fans, or stay in the shade.
