Question 1

What is a normal blood pressure reading at home?

Accepted Answer

Under 120/80 mmHg is normal, per the American Heart Association's categories. 120-129/under 80 is elevated, 130-139/80-89 is Stage 1 hypertension, and 140/90 or higher is Stage 2. Above 180/120 with symptoms is a hypertensive crisis and needs emergency care.

Question 2

How many times a day should I check my blood pressure?

Accepted Answer

Twice a day is the usual pattern: once in the morning before medication or food, once in the evening. Take two readings, a minute apart, each time and average them, then log all four numbers.

Question 3

Can I check my blood pressure right after waking up?

Accepted Answer

Yes, morning is one of the two recommended times, but sit quietly for 5 minutes first and check before coffee, exercise, or your morning medication, since any of those can raise the number.

Question 4

Does a wrist monitor work as well as an upper-arm monitor?

Accepted Answer

No. The American Heart Association recommends a validated upper-arm cuff. Wrist and finger monitors are more sensitive to arm position and give less reliable readings.

Question 5

Why is my blood pressure higher at the doctor's office than at home?

Accepted Answer

This is called white coat hypertension, a reading that runs higher in a clinical setting than it does at home. The reverse, masked hypertension, is a normal clinic reading with a higher home average. Both are why a pattern of home readings matters more than a single number.

Question 6

What cuff size do I need?

Accepted Answer

Measure around your bare upper arm at the midpoint. A cuff that's too small inflates the reading, and one that's too large can understate it. Most monitors come in standard and large-arm sizes, check the package before buying.

Question 7

Should I sit or lie down to check blood pressure?

Accepted Answer

Sit. Back supported, feet flat on the floor, legs uncrossed, and your arm resting on a table at heart level. Lying down or letting your arm hang unsupported both skew the number.
