What Causes Syncope Episodes: How To Prevent Fainting Spells

Many people may not be familiar with the term syncope. Syncope in a true sense is a medical term for a bout of blackout and fainting that is usually the result of poor blood supply to the brain. Loss of consciousness for a fraction of second or in some cases for few seconds or minutes happens when your heart rate slows down and your blood pressure drops. During this period, the blood supply to your brain may be hampered.

There are several triggering factors that can cause syncope attack. Sudden trauma to your finger tip or sight of blood can be a reason for syncope attack.

You may find many people suffering from such type of fainting spells which are usually harmless, except for an unwanted injury. A person regains his consciousness within seconds.

Causes Of Syncope Episodes

Syncope usually can occur at any age; however elderly individuals are more prone to this condition in comparison to young individuals. Almost 3 to 4 percent of elderly individuals may have the history of such episodes some time in their old age. What happens in a syncope attack is that certain portion of the nervous system is not functioning normally due to situational crisis. It may lead your heart to work slowly and widening of the blood vessels of the lower limbs. The blood that has to flow to your brain now flows more towards the lower limbs causing the person to faint.

Often the cause of syncope is not related to any disease but can be due to the following reasons:

  • Standing for long time as it happens during a parade (that is the reason many soldiers may faint while they are marching for a parade).
  • Some people faint at the sight of blood.
  • Emotional stress, fear and anxiety may be the cause.
  • Straining hard at bowel movements.
  • Fainting while standing for a long time in sun is common.
  • Rarely syncope may indicate a serious health trouble such as heart disease (irregularity in rate and rhythm of the heart known as arrhythmia), severe loss of blood, low blood sugar in a diabetic patient etc.

Certain risk factors that can cause syncope are:

  • Elderly age.
  • Use of recreational drugs.
  • Person who already suffers from heart disease, blood pressure.
  • Pregnant women.

Chances of syncope increase among elderly because:

  • They often take sedatives and other drugs such as diuretics, anti hypertensive etc. for age related diseases.
  • Physiological changes in their blood vessels and heart.
