Syncope is due to a temporary reduction in blood flow and therefore a shortage of oxygen to the brain. This leads to lightheadedness or a "black out" episode, a loss of consciousness. Temporary impairment of the blood supply to the brain can be caused by heart conditions and by conditions that do not directly involve the heart: If you do not have any medical illness, you have to control mind and take care to avoid long standing and keep moving if you have to stand for long time Syncope is most commonly caused by conditions that do not directly involve the heart. These conditions include: Postural (orthostatic) hypotension: Drop in blood pressure due to changing body position to a more vertical position after lying or sitting; Dehydration causing a decrease in blood volume. Blood pressure medications leading to low blood pressure. Diseases of the nerves to the legs in older people (especially with diabetes or Parkinson's disease) when poor tone of the nerves of the legs draws blood into the legs from the brain.
