What is Syncope or Fainting?

Syncope or fainting means losing consciousness temporarily resulting from a sudden decline in the flow of blood to our brain. Such a thing usually requires only some minutes or seconds. A majority of such episodes are not hugely concerning although frequent fainting may require the doctor’s attention immediately. This is also known as Syncope as mentioned or loss of consciousness or reduced/decreased consciousness along with passing out. 

Some of the pre-fainting symptoms include feeling clammy/cold, light-headed, dizzy, nauseous, sweaty, hot, weak, anxious or stressed and so on. Someone fainting may sometimes fall down or have a severe headache along with having changes in vision including black or whiteouts or seeing stars as well. They hear a ringing sound in the ears along with losing control of the muscles alongside. 

Causes of Syncope (Fainting)

There could be a few causes of fainting that you should learn more about, before venturing into possible syncope treatments. Fainting may happen due to a sudden blood pressure fall, leading to a lower flow of oxygen and blood to your brain. There are several reasons leading to this loss of consciousness in case of a blood pressure dip:

  • Carotid Sinus Syncope: It takes place when the neck’s carotid artery gets pinched or constricted. The blood vessel supplying the brain gets constricted if someone is wearing a really tight collar or has stretched the neck excessively or even has a neck bone that pinches the artery in question. 
  • Cardiac Syncope: This means fainting owing to heart issues. Several conditions may impact the amount of oxygenated blood that is pumped to your brain. 
  • Situational Syncope: This happens from specific body functions or movements leading to a blood pressure drop. This may lead to periodic fainting as well. 
  • Vasovagal Syncope: This may take place when someone witnesses something that is really stressful. This includes seeing any blood, emotional anxiety or stress, emotional or physical trauma, pain and so on. This leads to a reflex action that is known as the vasovagal reaction. The heart eventually slows down and pumps a lower quantity of blood, leading to a reduction in blood pressure levels. Hence, the brain does not get ample oxygenated blood and the individual faints as a result.
