> 140/90 mmHg. Definition of hypertension - high blood pressure - is > 140/90 mmhg.
140/90. The american heart association has recommended guidelines to define normal and high blood pressure. Normal blood pressure less than 120/80 pre-hypertension 120-139/ 80-89 high blood pressure (stage 1) 140-159/90-99 high blood pressure (stage 2) higher than 160/100.
Depends on how old. Optimal blood pressure is under 120/80. Risk for heart disease and stroke begins to rise at 115/75. The elderly are "allowed" a bit higher blood pressure because the arteries may be stiff and not tolerant of 'normal' blood pressure. However, if well tolerated, it's best to stay under 120/80 for life. Allowance in the elderly should be considered by your doctor based on your health.
What is considered high blood pressure? Mine normally ranges from 125/145 over 78-97. 24 yo, female, secondary activity.
For you. Try to stay below 140 / 90. You may be able to do this by cutting salt intake, have an appropriate weight for your height. If you can not keep it under see your doctor.
Blood pressure. Presently true hypertension is defined as several blood pressures above the range of 140 mmHg (top/systolic) and above 90 mmHg (bottom/diastolic). Prehypertension, those who at risk for developing hypertension, is defined in the ranges of 120-139/80-89.
Teen BP. Among adults, there are clear numerical guidelines for diagnosis, but this is not true for teenagers. This is mostly because teenagers do not have the same risks (such as a heart attack) as adults. As with adults, adolescents with BP levels greater than or equal to 120/80 mmHg should be considered prehypertensive. “Hypertension is defined as average SBP and/or DBP that is greater than or equal to the 95th percentile for sex, age, and height on three or more occasions” “Prehypertension in children is defined as average SBP or DBP levels that are greater than or equal to the 90th percentile, but less than the 95th percentile”
Varies with age. The normal blood pressure for children increases as they grow older. Certainly any systolic blood pressure greater than 135 in a near adult would be worrisome and lower pressures in children who are younger. You can do a google search for "blood pressure tables for children".
Above 140/90. The blood pressure is considered high when it is persistently above 140/90; however if someone always has a blood pressure that is at 90/60 (without medication), for example and feels fine but start having symptoms (headache, light headed etc...) when the BP goes above the usual 90/60, it can be considered high blood pressure for this particular person even when the BP does not go above 140/90.
L40/90. Most would agree that a pressure over 140/90 would be high for a 20 year old.
