Bp Difference In Right And Left Arms

My BP is always higher in my left arm e.g. Left arm 150/58 - right arm 124/68, Left arm

158/61 - right arm - 120/64. These type readings are constant and taken within a few

minutes of each other. Is this type of difference normal, or something I should be concerned about and see a doctor?


Hi Realm,

It is not unusual for your blood pressure to be different in one arm than the other. Blood pressure may be slightly higher in your dominant arm. For example, if you are right-handed, you may get a higher blood pressure reading when taken on your right arm. Usually the difference between arms is 10 mm Hg or less. Now, if you have heart disease, studies show the difference between arms to be greater. The arm with the higher blood pressure, is the one you should monitor.

Here is a post that may help:

What if my blood pressure is different in both arms?

I recommend you discuss the difference you are seeing with your physician.

All the best,
