A repeated difference of more than 10 mm Hg in blood pressure measurement between the arms can be a sign of a health problem such as: Blocked arteries in the arms, known as peripheral artery disease. Diabetes.
The sensitivity for the detection of hypertension was 90.6% when BP was measured only at right arm, and 83.4% when measured only at left arm. Corresponding sensitivity were 87.9% and 87.1% in men, and 95.4% and 76.9% in women.
As for home blood pressure monitoring, he said, if people repeatedly detect a significant difference between the arms, they should tell their doctor. Clark was also in favor of doctors checking both arms, at least once -- in part to get a more accurate gauge of patients' blood pressure.
Blood pressure has a daily pattern. Usually, blood pressure starts to rise a few hours before a person wakes up. It continues to rise during the day, peaking in midday. Blood pressure typically drops in the late afternoon and evening.
Blood Pressure Cuff Placement
If the cuff is too small, it can add 2 to 10 points to your bp measurement. Be sure to roll up your sleeve for a blood pressure test and also let your doctor know if the cuff feels too tight around your arm.
Take it first in the morning before eating or taking any medications. Take it again in the evening. Each time you measure, take two or three readings to make sure your results are the same. Your health care provider might recommend taking your blood pressure at the same times each day.
Something as simple as keeping yourself hydrated by drinking six to eight glasses of water every day improves blood pressure. Water makes up 73% of the human heart,¹ so no other liquid is better at controlling blood pressure.
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.
Your first blood pressure reading will almost always be higher than the second due to a wide range of factors, both environmental and psychological. These factors include white coat syndrome, stress, and having a full bladder.
The American Heart Association recommends repeating a BP measurement at the same clinic visit with at least 1 minute separating BP readings,2 yet in busy primary care practices BP often is measured only once.
For 30% of them, the systolic pressure—the first number of a blood pressure reading—was 5 mm Hg or more different from the office reference measurement. The diastolic pressure (second number) was similarly inaccurate. "In one patient, the pressure was off by 21 mm Hg," Dr. Hiremath says.
Call 911 or emergency medical services if your blood pressure is 180/120 mm Hg or greater and you have chest pain, shortness of breath, or symptoms of stroke. Stroke symptoms include numbness or tingling, trouble speaking, or changes in vision.
While both numbers in a blood pressure reading are essential for diagnosing and treating high blood pressure, doctors primarily focus on the top number, also known as systolic pressure.
Bananas. Bananas contain potassium, which can help manage hypertension. One medium-sized banana contains around 422 milligrams (mg) of potassium. According to the American Heart Association (AHA) , potassium reduces the effects of sodium and alleviates tension in the walls of the blood vessels.
According to the Heart Foundation of Australia, as a general guide: blood pressure below 120/80 mmHg can be classified as 'optimal'; blood pressure between 120/80 and 129/84 mmHg is 'normal'; and. blood pressure between 130/85 and 139/89 mmHg is classified as 'high-normal'.
Caffeine may cause a short, but dramatic increase in your blood pressure, even if you don't have high blood pressure. It's unclear what causes this spike in blood pressure. The blood pressure response to caffeine differs from person to person.
Don't check your blood pressure too often.
Some people find that they become worried or stressed about small changes in their readings if they take them too often. Worrying can also raise your blood pressure in the short term, making your reading higher than it should be.
The resulting anxiety can elevate blood pressure 10 points or more.” Studies have shown that clinics rarely take two or more blood pressure readings, even though the ACC/AHA guidelines suggest that doing so could reduce the effects of WCH.
“I advise people diagnosed with hypertension to check their blood pressure twice per day until they have it under control,” she says. “After that, it's fine to check it one to two times per week.”
Practice stress relief
For example, breathe deeply and exhale slowly. Try a few of these breaths before your blood pressure reading. Reciting a poem or verse in your mind may help you relax, too.
Insomnia is linked to high blood pressure and heart disease. Over time, poor sleep can also lead to unhealthy habits that can hurt your heart, including higher stress levels, less motivation to be physically active, and unhealthy food choices.
Blood pressure changes throughout the day. Your blood pressure is typically at its lowest right after waking up. It tends to vary by up to 30% across the day. This is because of hormone changes, activity level, and eating.
