BP Range. BP of 120/80 is the 'normal' for most people. It varies by age, time of the day, activity level, ingestion of sodium in foods and drinks, use of alcohol, illicit and prescription drugs. Low BP is of no concern unless producing symptoms such as dizziness, weakness, fatigue, etc. Lower bps causes less cardiovascular stress, reducing heart, brain and kidney disease.
No. No, if this is the larger number(systolic bp) it is ok, if it is smaller number (diastolic bp) , then it is too high.
Blood pressure. No, the top (systolic) BP number at 116, would be very acceptable and normal, not low.
