Common questions
What is a normal blood pressure by age?
For most adults of any age, a reading below 120/80 is considered normal. Blood pressure does tend to creep up as arteries stiffen with age, but higher numbers are still worth treating, not just accepting. Many doctors aim for below 130/80 in older adults, though the right target depends on your health, so confirm yours with your own doctor.
Why is my blood pressure higher at the doctor than at home?
Many people run higher in a clinic because of nerves, rushing in from the parking lot, or talking during the measurement. This is called white coat effect, and it is why home readings taken calmly often give a truer picture. Bring a week of home readings to your appointment so your doctor can compare.
How do I measure my blood pressure correctly at home?
Sit quietly for five minutes first, with your back supported, feet flat on the floor, and your arm resting at heart level. Use a cuff on your bare upper arm, not your wrist, and do not talk during the reading. Take two readings a minute apart, morning and evening, and write them down.
When is a blood pressure reading an emergency?
A reading of 180/120 or higher along with chest pain, shortness of breath, a bad headache, vision changes, weakness, or trouble speaking is an emergency. Call 911 right away rather than waiting to retest. If you get 180/120 with no symptoms, rest five minutes and check again, and call your doctor the same day if it stays that high.
