Free Blood Pressure, BMI

 

Blood pressure (BP) is the pressure (force per unit area) exerted by circulating blood on the walls of blood vessels, and constitutes one of the principal vital signs. The predominantly used unit for blood pressure measurement is mmHg (millimeter of mercury).


The following classification of blood pressure applies to adults aged 18 and older. It is based on the average of seated blood pressure readings that were properly measured during 2 or more office visits.

The body mass index (BMI) is a controversial statistical measurement which compares a person's weight and height. It may be a useful tool to estimate a healthy body weight based on how tall a person is.
Adults whose BMI is between 18.5 and 22.9 have a low risk of developing heart disease and other health problems such as diabetes. Those with a BMI between 23 and 27.4 are at moderate risk while those with a BMI of 27.5 and above are at high risk of heart disease and other health problems.
