Doctors often warn about the dangers of high blood pressure or hypertension, as just under 30 percent of adults in the US have high blood pressure, according to the Centers for Disease Control and Prevention. Many people are unaware low blood pressure or hypotension is also a serious problem which can result in dizziness, seizures, or shock. Those who are health-conscious should regularly check and track their blood pressure — search for the best blood pressure monitor of 2016 online, for example, or ask a family doctor to recommend a device.
Blood pressure monitors give a reading of two numbers that indicate how hard the heart beats to push blood through the circulatory system. New research suggests healthy blood pressure should be no higher than 115/75 mmHg, according to Harvard Medical School and the National Institutes of Health, while 90/60 mmHg or lower is considered too low a blood pressure. With low blood pressure, oxygenated blood may not be reaching the brain and other vital organs quickly enough. This can cause nausea, lightheadedness, or fainting, which can then result in shock or falls. While a significant portion of the population needs to lower their blood pressure, too-low blood pressure is a real health issue that cannot be overlooked.
Low blood pressure becomes more common as people age. Seniors often suffer from orthostatic hypotension, which is hypotension that occurs when they shift positions, such as going from sitting to standing or vice versa, according to the National Heart, Lung, and Blood Institute. Orthostatic hypotension happens because the body does not adjust the blood pressure in time. The resulting dizziness and blurry vision can then lead to falls, fractures, and other injuries, which can be potentially fatal for the elderly.
Blood pressure normally drops during sleep, but can also be lowered by diabetes, anemia or blood loss, dehydration, long periods of sitting, and certain medications. To accurately measure blood pressure, use a blood pressure monitor and take readings throughout the day. If the numbers become too low or change unexpectedly, consult a doctor right away — even low blood pressure can be high-concern.
