Vasovagal Syncope – Causes, Symptoms, Treatment

If you have ever fainted, you’ve experienced vasovagal syncope. Vasovagal syncope occurs when over stimulation of the vagus nerve occurs. This causes the heart-rate to slow and blood pressure to drop, shutting off blood flow to the brain. It happens very quickly and then corrects itself. Temporarily losing consciousness can cause injury or even death.

An oncoming vasovagal syncope can be identified by knowing its symptoms. They can be as simple as lightheadedness and tunnel vision, or they can encompass feelings of nausea, ringing in the ears, incomplete thoughts or statements, feeling hot and beginning to sweat, and physical weakness. Many individuals suffering from vasovagal syncope have reported feeling nervous or having visual disturbances before fainting.

Determining the trigger to a vasovagal syncope is important in understanding how to identify and prevent it from occurring again. Vasovagal syncope can be caused by many things, most often by standing up very quickly, smoking, and unpleasant or painful triggers such as trauma, seeing blood, and high temperatures. Some uncommon causes of vasovagal syncope are hunger, arousal, urination, coughing, and vomiting. Every individual has a unique trigger.

It is important to see a doctor if you are experiencing vasovagal syncope to determine the cause of fainting. Doctors will check to see if the fainting is a heart-related or posture-related before proceeding to treatment. There is no specific treatment for vasovagal syncope, but since it can be dangerous to leave unmanaged, it is important to identify the triggers causing it and treat them.

Depending on the cause of the vasovagal syncope, medications can be administered to control blood pressure, fear and anxiety, and blood vessel constriction. Often times, it is advised to avoid triggers, and to become educated on how to identify an oncoming vasovagal syncope and prevent falling or collapsing to avoid injury.

Vasovagal syncope is a common occurrence, and most people have experienced it before. It is nothing to be afraid of if you are educated on what happens during the vasovagal syncope, and how to identify its triggers. The important thing is to avoid triggers and prevent injury during the onset of it.
