When we take the blood pressure, we usually do it on the right arm, and although this tends to be a little higher, the truth is that the ideal is to do it on both arms, since discovering a considerable pressure difference could save our lives. Just as you read it! Discover why blood pressure is different in each arm.

How much can blood pressure vary from one arm to the other?
Normally, the variation in blood pressure between one arm and the other usually has a slight difference of about five points or less between both. However, in most people, blood pressure readings on the right arm and the left arm they should be quite similar.
Systolic difference: difference in systolic blood pressure (the highest figure) between one arm and the other is usually less than 10 mm Hg. For example, if the systolic blood pressure in the right arm it is 120 mm Hg, in the left arm it could be 110-130 mm Hg without being a cause for concern. Diastolic difference: the difference in diastolic blood pressure (the lowest number) between both arms is also generally less than 10 mm Hg. For example, if the diastolic blood pressure in the right arm it is 80 mm Hg, in the left arm it could range between 70-90 mm Hg.

Although it is normal to have a slight blood pressure difference between the arms, the reality is that the right arm is usually a little higher. According to a article published by National Library of Medicine, The right arm is usually the strongest, but the position of the arm or resistance to blood flow also interferes.
What does it mean to have different pressure in each arm?
In some cases, there are health problems as the atherosclerosis (hardening of the arteries) or arterial stenosis (narrowing of the arteries) that can cause considerable differences between a blood pressure reading from one arm to the other. However, these are not the only conditions that could cause it:
Risk of cerebral embolism: a difference in blood pressure It could be due to blockage or stenosis in an artery that supplies blood to the brain. However, there is a risk of causing a stroke. This occurs when a clot breaks away from a narrowed artery and travels to the brain, causing a cerebrovascular accident.Increased risk of thrombosis: if there is a significant discrepancy in the blood pressure between arms Due to atherosclerosis or arterial stenosis, the likelihood of blood clots forming in affected arteries may increase. Blood clots can completely block an artery, which can lead to a heart attack or stroke, in the worst case. Indicator of arterial disease: a noticeable difference in the blood pressure in both arms It may indicate underlying arterial disease, such as atherosclerosis or arterial stenosis. These conditions can reduce blood flow to the heart and brain, increasing the risk of cardiovascular problems.

On the other hand, if a major artery supplying the heart shows a lower blood pressure Due to a blockage or stenosis, the heart may have to work harder to pump blood. This can increase stress on the heart and raise the risk of a heart attack.
Which arm to choose to measure blood pressure?
The most recommended is measure blood pressure in both arms in case you notice a considerable difference; Otherwise, it is recommended to choose a specific arm and use it consistently for all measurements.
Now that you know why there can be a large difference in blood pressure between one arm and the otherdo not hesitate to follow our recommendations and take good care of your heart.
