Vasovagal syncope occurs when a person faints. Certain things trigger the body to overreact. It can be from something as simple as the sight of blood or something as serious as a trauma. It is sometimes referred to as neurocardiogenic syncope. Vasovagal syncope causes the sufferer’s blood pressure and heart rate to drop suddenly. This prevents the blood from flowing to the brain and can cause a brief loss of consciousness. There is no cure for vasovagal syncope, and in most cases, it is not harmful.
Vasovagal occurs when the nervous system malfunctions and can no longer regulate blood pressure or heart rate. This happens due to a trigger. These triggers can vary, and there sometimes is no clear trigger at all. There are a few other things that can also cause this reaction. Those things include:

Most people will only experience vasovagal syncope a few times in their lives. It may be unpredictable, but the only dangers associated with it are injuries that may occur as a result of falling. People who experience vasovagal syncope often can work on preventative treatment methods to help reduce the episodes. Once other health problems are ruled out and triggers are determined, patients can learn to avoid the triggers and live normal lives. People who are affected by the condition often have it for the rest of their lives and simply have to learn to live with it.
