Low Blood Pressure | Hypotension Low blood pressure or hypotension is persistent abnormally low blood pressure. Blood pressure is the pressure of blood in your arteries. The blood circulation is a closed system in which the pressure varies constantly. It rises to a peak, called the systolic pressure, at the height of the contraction of each heartbeat. Then it falls to a lower level, called the diastolic pressure, which it reaches just before each heartbeat. The diastolic pressure is the running pressure between beats. Blood pressure varies between individuals and throughout the day. Blood pressure is normally above 90/60 mmHg. Your blood pressure varies by large amounts, depending on what you are doing. The lowest blood pressures occur when you are asleep or if you relax all your muscles. Standing up, exercising or anxiety all cause an increase in blood pressure. In a single day your blood pressure may vary by 30 to 40 mmHg systolic with similar proportionate changes in diastolic pressure. This is why when you have your blood pressure level assessed it is so important to have it measured under the same conditions every time. What are the symptoms of low blood presure? Hypotension usually means blood pressure that is lower than 90/60 mmHg (millimeters of mercury) or is low enough to cause symptoms.
