Syncope or fainting is a short loss of consciousness and usually followed by spontaneous recovery. The cause of fainting is due to decreased blood flow to the brain because of low blood pressure. Generally before the loss of consciousness occurs, the victim may experience one or more of the following symptoms, lightheaded, pale skin, sweating, nausea, vomiting and feeling warm.

There are several causes of fainting some are non-serious while others are life-threatening. There are three categories involved in this medical condition: heart or blood vessel-related, reflex, and orthostatic hypotension.

Heart-related causes are the most serious among the three categories, while the reflex or neutrally mediated are the most common. Abnormal heart rhythm, blockages of blood vessels, problems with the heart valves or heart muscles are some of the reasons why fainting can occur. Neurally mediated or reflex, fainting occurs when blood vessels expand and there is low heart rate inappropriately. The following are a few of the examples of neurally mediated syncope: exposure to blood, pain, and strong feelings in instances such death of a loved one or someone you know. Additionally, pressing the carotid sinus in the neck can also cause fainting. The final category of syncope is due to sudden drop in blood pressure when you change position from supine to standing up. Dehydration and hemorrhage can also be a cause.

To detect fainting and know the underlying cause, your doctor might need to perform the following to determine the cause. A medical history, physical examination, and ECG are the most effective ways of determining the underlying cause.
Though the cardiac syncope is considered the most fatal among the three since it is closely associated with serious heart conditions. Non-cardiac syncope is not life-threatening, however, the accidents and injuries that happen afterward are debilitating.
