High blood pressure is now generally defined as 130 or higher for the first number, or 80 or higher for the second number (previously it was 140/90).
As a general guide: high blood pressure is considered to be 140/90mmHg or higher (or 150/90mmHg or higher if you’re over the age of 80) ideal blood pressure is usually considered to be between 90/60mmHg and 120/80mmHg.
When treating hypertension in patients over the age of 85 years, the usual target blood pressure is 150/80 mmHg for reduction of the risk of stroke, heart attack , and other cardiovascular events.
What is normal blood pressure according to age?
A hypertensive crisis is a severe increase in blood pressure that can lead to a stroke. Extremely high blood pressure — a top number (systolic pressure) of 180 millimeters of mercury (mm Hg) or higher or a bottom number (diastolic pressure) of 120 mm Hg or higher — can damage blood vessels.
Normal pressure is 120/80 or lower. Your blood pressure is considered high (stage 1) if it reads 140/90. Stage 2 high blood pressure is 160/ 100 or higher. If you get a blood pressure reading of 180/110 or higher more than once, seek medical treatment right away.
The previous guidelines set the threshold at 140/90 mm Hg for people younger than age 65 and 150/80 mm Hg for those ages 65 and older . This means 70% to 79% of men ages 55 and older are now classified as having hypertension . That includes many men whose blood pressure had previously been considered healthy .
The new guidelines change nothing if you’re younger than 60. But if you’re 60 or older, the target has moved up: Your goal is to keep your blood pressure at 150/90 or lower. If you have kidney disease or diabetes , your target used to be 130/80 or lower; now it’s 140/90 or lower.
In severe cases, low blood pressure can be life-threatening. A blood pressure reading lower than 90 millimeters of mercury (mm Hg) for the top number (systolic) or 60 mm Hg for the bottom number (diastolic) is generally considered low blood pressure .
However, most studies show a greater risk of stroke and heart disease related to higher systolic pressures compared with elevated diastolic pressures. That’s especially true in people ages 50 and older, which is why doctors tend to monitor the top number more closely.
Research has indicated that blood vessels naturally ‘harden’ with age, losing their elasticity. This may be one explanation for why older people are more at risk of developing high blood pressure .
Here are some simple recommendations: Exercise most days of the week. Exercise is the most effective way to lower your blood pressure . Consume a low-sodium diet. Too much sodium (or salt) causes blood pressure to rise. Limit alcohol intake to no more than 1 to 2 drinks per day. Make stress reduction a priority.
Normal blood pressure: 90/60 to under 120/80 mm Hg. Prehypertension , or risk for hypertension : 120-139/80-89 mm Hg. Stage 1 hypertension : 140-159/90-99 mm Hg. Stage 2 hypertension : over 160/100 mm Hg.
Caffeine can cause a short, but dramatic increase in your blood pressure , even if you don’t have high blood pressure . It’s unclear what causes this spike in blood pressure . Some researchers believe that caffeine could block a hormone that helps keep your arteries widened.
