Hello, I went through your, Syncope refers to a sudden loss of consciousness often accompanied with collapse, more commonly known as a blackout or faint. Syncope is caused by a lack of blood or oxygen to the brain. When this happens, the brain attempts to increase blood flow to itself by diverting blood away from the rest of the body. There are a number of situations that can induce syncope. Too little food or water, low blood sugar (hypoglycaemia), intense physical exercise, and standing up too quickly can all cause an episode of fainting. Additionally, low blood pressure (hypotension) and an abnormal heart rhythm (arrhythmia) can also cause a lack of blood to the brain or lesions in brain or carotid artery could induce syncope. You need to be undergo physical examination and some tests to find cause. Please consult MD medicine physician.
