4. Dizziness or Fainting: An Alarming Symptom of Impaired Blood Flow
Dizziness and fainting, also known as syncope, can be alarming symptoms of severe aortic stenosis. These episodes occur when the narrowed aortic valve prevents adequate blood flow to the brain, causing a temporary drop in blood pressure. This reduced blood flow can lead to lightheadedness, dizziness, or even fainting.
Fainting episodes often occur during physical activity, as the heart struggles to meet the increased demand for oxygen-rich blood. However, they can also happen at rest or when changing positions suddenly, such as standing up from a seated position.
If you experience unexplained dizziness or fainting, it is crucial to consult a healthcare professional immediately. These symptoms could indicate severe aortic stenosis or another serious heart condition that requires prompt attention. (4)
