A BP reading of 90/80 is normal as long as the higher (systolic) remains at or more than 90 up to 120. The 80 is consistent with normal diastolic pressure.
Systolic blood pressure for most healthy adults falls between 90 and 120 millimeters of mercury (mm Hg). Normal diastolic blood pressure falls between 60 and 80 mm Hg. (By convention, an individual’s blood pressure is written as systolic/diastolic blood pressure, e.g., 120/80). Current guidelines define normal blood pressure as lower than 120/80. Blood pressures between 120/80 and 140/90, which used to be considered “pre-hypertension
,” now are considered too high. High blood pressure
increases the risk of developing heart disease
, kidney disease, hardening of the arteries (atherosclerosis
), eye damage, and stroke.
