- What About Low Blood Pressure?
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: Although I can find all the information I want about high blood
- pressure, nothing much seems to be written about low pressure, which is my
- problem. What does low pressure mean, and is it dangerous? I am not on any
- medication, and frankly do not know what to do about it. Please help.

- ANSWER: An average normal for blood pressure is the famous 120/80, where the
- higher number (systolic pressure) represents the pressure in the arteries each
- time the heart contracts, and the 80 (diastolic) shows the pressure between
- beats. While this is considered the average normal, "normal" blood pressure
- depends upon many factors, including age and sex. However, any pressure above
- 140/90 is considered "high" and deserves medical attention and treatment.
- Pressure that is too high places undue stress on the arteries of the body, the
- heart, and kidneys as well. A diagnosis of "low blood pressure" may be
- considered when the pressure drops below the 120/80 mark in an adult. And it
- may not be a problem at all.
- Generally, a finding of a lower pressure in an individual who is
- otherwise in a good state of health may be a positive sign. It is frequently
- found in people who are physically fit as the result of regular exercise, or
- have recently lost weight. It is a sign of fine cardiovascular condition.
- And it is also a sign that the patient is relaxed and at ease during the
- examination. When a person is tense during the blood pressure examination,
- the blood pressure may be temporarily elevated, a condition that is referred
- to as "white coat hypertension".
- There is one type of low pressure that can be classified as a problem
- though. It is called "orthostatic hypertension". It this situation the
- pressure drops to low levels when a person stands up quickly, or gets out of
- bed too rapidly. There is a sensation of lightheadedness, or dizziness, due
- to the sudden drop in pressure. The situation can usually be avoided by
- rising more slowly and deliberately.
