What is the most common cause of syncope?

The type you have depends on what causes the problem. Vasovagal syncope is the most common type of syncope. It is caused by a sudden drop in blood pressure, which causes a drop in blood flow to the brain. When you stand up, gravity causes blood to settle in the lower part of your body, below your diaphragm.

What is the ultimate cause of syncope?

Vasovagal (Cardioneurogenic) Syncope. Vasovagal syncope (also known as cardioneurogenic syncope) is the most common cause of syncope. 6 It is caused by the sudden dilation of blood vessels in the legs in response to an exaggerated neurological reflex.

What are the 4 classifications of syncope?

Syncope is classified as neurally mediated (reflex), cardiac, orthostatic, or neurologic (Table 1).

How do you stop syncope attacks?

To prevent fainting, stay out of hot places and don't stand for long periods. If you feel lightheaded, nauseous, or sweaty, lie down right away and raise your legs. Most people with occasional vasovagal syncope need to make only lifestyle changes such as drinking more fluids and eating more salt.
