Know about low blood pressure, diagnose and treatment


Normal blood pressure is 120/80 mm hg where 120 is the systolic pressure and 80 is the diastolic pressure. Low blood pressure is an abnormal condition where a person’s blood pressure is much lower than usual, which can cause symptoms such as dizziness or lightheadedness.

When the blood pressure is too low, there is inadequate blood flow to the heart, brain, and other vital organs. A blood pressure level that is borderline low for one person may be normal for another.

The most important factor is how the blood pressure changes from the normal condition. Most normal blood pressures fall in the range of 90/60 mm Hg to 130/80 mm Hg, but a significant change, even as little as 20 mm Hg, can cause problems for some persons.

How to find out low Blood Pressure ?

We find out the Blood pressure by measurement using two numbers – the systolic first and others the diastolic.
Blood pressure is measured using an inflatable cuff. This is situated around the upper arm. The cuff is inflated and the doctor or nurse listens to the artery just below the cuff as the air is then released. When they can hear the heart beat, they will record the systolic pressure. When the sound disappears, they will record the diastolic pressure. Sometimes an automatic blood pressure recording machine is used.

Blood pressure may be measured while lying down and then while standing. Blood pressure has to be checked regularly.

How can control low blood pressure?

The treatment of low blood pressure is directed toward the underlying cause. Checking whether you are drinking enough and are not dehydrated may be important.

If an underlying disorder, such as a heart condition is suspected then it may be advisable to go to hospital for tests and treatment. If medications are suspected of causing hypotension the doctor will probably advise a change of drug or dosage. Bed rest and assistance with daily activities are needed until the condition improves.
