What is dizziness?
Dizziness is a sensation of light-headedness or feeling faint.
What are the causes of dizziness in children?
Main Cause. Usually due to reduced blood flow to the brain for a short time. It can be triggered by many normal events:
- Standing too long in one place. Reason: This causes pooling of blood in the legs.
- Standing up suddenly. Reason: This causes sudden drop in blood pressure.
- Dehydration. This can be from losing fluids and/or from not drinking enough fluid.
- Low oxygen (such as when running and out of breath). Reason: Lower than normal oxygen levels can't meet body's needs for a short time.
- Too much sun or hot tub use. Reason: Increased sweating causes fluid loss.
- Sweating from sports or hard work. Reason: Sweating causes fluid loss.
- Fasting. Skipping a meal causes low blood sugar.
- Motion sickness. Main symptoms are dizziness and nausea.
- Viral Syndrome. Patients with viral illnesses (e.g., colds, flu) often say they are a bit dizzy. This is never the only symptom. It may relate to weakness from being sick.
- Vertigo (Serious). In addition to dizziness, the child complains that the room is spinning. They can't walk if they have vertigo. True vertigo is very rare in children. It's usually caused by middle ear disease.
