Warning Signs Of Hypotension (Low Blood Pressure)

Loss Of Consciousness

Loss of consciousness can occur as a result of hypotension, usually after patients experience dizziness and nausea. This form of consciousness loss is medically called syncope, and occurs when individuals temporarily lose consciousness, with the most common underlying cause being a lack of sufficient blood flow to the brain. The most common type of syncope is neutrally mediated syncope. This occurs when an individual suffers neutrally mediated hypotension after standing for long periods and passes out. It's a very common reason for emergency room visits. Young adults and children are more likely to experience neutrally mediated syncope, though it is possible to have an episode regardless of age. Postural orthostatic tachycardia syndrome patients sometimes lose consciousness immediately after standing up if their drop in blood pressure is severe enough. To receive a POTS diagnosis, an individual's blood pressure must drop at least thirty points when they stand.
