Low Blood Pressure
What is low blood pressure?
First of all, blood pressure refers to the pressure in the arteries throughout the body. This pressure is the driving force which sends the blood from the higher pressure regions (arteries) to the lower pressure regions (the organs and veins). When measuring an individual’s blood pressure, two values are given: the systolic and diastolic.
- Systolic pressure refers to the pressure in the arteries when the heart muscle contracts and pushes the blood into the arteries.
- Diastolic pressure refers to the pressure in the arteries when the heart is relaxed.
Blood pressure is displayed with the systolic pressure over the diastolic. Normal blood pressure is considered 90 to 120 for systolic and 60 to 80 for diastolic, with the average falling around 120/80 (systolic / diastolic).
How do I know if I have low blood pressure?
Unlike high blood pressure, low blood pressure (which is also referred to as hypotension) is not identified by taking a simple measurement. It must be determined by the presence of symptoms as well as the measured value. This is the case because “normal blood pressure” differs from one person to the next. For example, one person could have a normal blood pressure reading of 100/60, yet not exhibit any symptoms of low blood pressure. Thus, they are considered perfectly healthy. On the other hand, an individual who is normally at 120/80 and then drops to 100/60 will quite possibly display the symptoms of hypotension.
Is low blood pressure always considered unhealthy?
No, definitely not. Individuals who are physically fit with strong cardiovascular systems are considered healthy and actually have a decreased risk for heart attack and stroke. As long as these individuals don’t exhibit any of the telltale symptoms for hypotension, there is no cause for concern. However, low blood pressure accompanied by any of the symptoms discussed below could indicate that the low blood pressure is a problem.
What are the symptoms of hypotension?
The most common symptoms of hypotension are dizziness, lightheadedness and fainting, which are caused by a decrease in blood flow to the brain. This causes the brain cells to receive a less than desirable amount of oxygen and nutrients. If dizziness and / or lightheadedness are experienced after an individual stands from a lying or sitting position, the condition is referred to as orthostatic hypotension.
Orthostatic hypotension results because changing the body’s posture from sitting (or lying down) to standing causes a large volume of blood to rush to the lower extremities, resulting in a decrease in blood pressure. Someone who has low blood pressure to begin with is more likely to experience dizziness or lightheadedness when standing up. Individuals with a normal blood pressure will also experience a decrease in blood pressure when standing up, but their bodies are better able to accommodate and are much less likely to feel ...
