Fainting

Fainting is an instantaneous loss of consciousness that is quickly followed by a full recovery on its own. Generally speaking, this lasts anything from a few seconds to a few minutes. This results from a momentary reduction in blood flow to the brain. Fainting occurs due to very common cardiovascular diseases due to sudden decrease in cardiac output causing cerebral ischemia, or due to cardiac diseases: aortic valve stenosis, left atrial mucinous tumor, cardiomyopathy hypertrophy,...

Anyone, regardless of age or health status, has the potential to faint. Although fainting is often not a matter of alarm, it can occasionally be a symptom of a serious disease. To determine the reason for your frequent fainting episodes, talk to your doctor. A physical examination, a review of your medical history, and questions regarding the symptoms you had before fainting will be used by your doctor to diagnose you. By evaluating the quantity of blood and the speed at which it moves through various body parts, tests will look for cardiac abnormalities.
