Every two years.The frequency with which you should check your blood pressure will depend on your current health. But the average adult who has normal blood pressure levels should have their blood pressure checked at least once every 5 years. However, as you get older, it becomes more likely that you will develop high blood pressure, so you will want to check your blood pressure more frequently; for older men and women, it is best to get your blood pressure checked every year, at least.
For those with high blood pressure and other health problems, you may need to check your blood pressure much more frequently. Some individuals even need to check their blood pressure multiple times a day. So follow your doctor’s instructions and check as frequently as he or she recommends.
