Introduction
Feeling lightheaded or fainting is frightening—and often dismissed as a “one-time thing.” But repeated dizziness or passing out can indicate serious heart disease. In Brampton, Mississauga, and Milton, I frequently see patients who ignore these episodes until they worsen.
Causes of Dizziness and Fainting
Heart-Related
- Arrhythmias: Fast or slow heart rhythms reduce blood flow to the brain.
- Valve disease: Narrowed valves reduce circulation.
- Cardiomyopathy: Weak heart muscle limits oxygen delivery.
Non-Heart Related
- Dehydration or low blood pressure.
- Neurological conditions.
Medication side effects.
Red Flag Situations
- Fainting during exertion.
- Fainting with chest pain or palpitations.
- Sudden collapse without warning.
