Also know, what causes a vasovagal attack?
Vasovagal syncope (also called cardio-neurogenic 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.
Also Know, how can you stop a vasovagal attack? 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.
Hereof, what is a vasovagal?
Vasovagal syncope (vay-zoh-VAY-gul SING-kuh-pee) occurs when you faint because your body overreacts to certain triggers, such as the sight of blood or extreme emotional distress. It may also be called neurocardiogenic syncope. The vasovagal syncope trigger causes your heart rate and blood pressure to drop suddenly.
Is a vasovagal attack serious?
A vasovagal attack itself is not serious; however, injury is possible during a fainting episode. Prolonged standing is associated with vasovagal attacks because blood may pool in the legs, thus reducing blood flow to the brain. Heat exposure can also lead to a vasovagal attack.
