Signs of low blood pressure
Would you recognise the signs of low blood pressure if you developed them?
Low blood pressure is an interesting condition and some of the signs and
symptoms are very typical - textbook almost in their predictability. However, over
the years a whole range of more unusual symptoms and signs have become
linked to low blood pressure. Some people say that these symptoms and signs
are caused by the low blood pressure - others would judge that the low blood
pressure and the other signs simply go together as part of a bigger picture - or
as two manifestations of one single underlying condition.
So what are the signs of low blood pressure?
Well, first a lesson in medical terminology. Strictly speaking "signs" are
something that a doctor or nurse can observe independently of you saying
anything about them. Signs are objective - in other words if two different
observers looked at you they would independently find the same thing and be
able to document what they found.
Symptoms on the other hand are subjective. Symptoms are the feelings that a
patient experiences - put into descriptive words for the benefit of others.
So - in that real sense - the signs of low blood pressure are different from the
symptoms of low blood pressure, although the two are closely related.

Signs of low blood pressure
The objective signs of low blood pressure therefore include:
- clamminess or sweating
- pallor
- poor balance
- impaired memory or mental ability
and of course:
- systolic blood pressure less than 90
- diastolic blood pressure less than 60
Other signs of low blood pressure are sometimes found but those listed above are the most commonly
seen.
