Question: Why is blood pressure higher in left arm than right arm?

Generally, a small difference in blood pressure readings between arms isn’t a health concern. However, a difference of more than 10 millimeters of mercury (mm Hg) for either your top number (systolic pressure) or bottom number (diastolic) may be a sign of blocked arteries in the arms, diabetes or other health problem.

Why is blood pressure higher in left arm?

But large ones suggest the presence of artery-clogging plaque in the vessel that supplies blood to the arm with higher blood pressure. Such plaque is a signal of peripheral artery disease (cholesterol-clogged arteries anywhere in the body other than the heart).

Which arm usually has higher blood pressure?

Higher pressures are more frequent in the right arm and range in most individuals from 10 to 20 mmHg or greater in systole, and to a similar extent but less often in diastole. A BP difference between the left and right arms—even when large—is statistically a normal variant and need not necessarily cause concern.

Which hand is more accurate for blood pressure?

Abstract. Guidelines for the management of hypertension recommend that blood pressure (BP) should be measured twice at every visit; it should be measured in both arms at the first visit, and the right arm BP or higher BP should be recorded.

Why is my BP different in each arm?

Generally, a small difference in blood pressure readings between arms isn’t a health concern. However, a difference of more than 10 millimeters of mercury (mm Hg) for either your top number (systolic pressure) or bottom number (diastolic) may be a sign of blocked arteries in the arms, diabetes or other health problem.

Does dehydration cause high blood pressure?

Hypertension- High blood pressure is common in people who are chronically dehydrated. When the body’s cells lack water, the brain sends a signal to the pituitary glad to secrete vasopressin, a chemical that causes constriction of the blood vessels. This causes blood pressure to increase which leads to hypertension.

Does arm position affect blood pressure?

Can you take blood pressure multiple times in a row?

Check it twice

It’s ideal to measure your blood pressure twice a day for two weeks leading up to a doctor’s appointment, or following a change in medication. At each sitting, measure your blood pressure three times, but discard the first reading as it tends to be inaccurate.
