Fluctuating blood pressure can be normal, as blood pressure varies somewhat throughout the day. Stress, exercise, and sleep can all make a difference. But if your blood pressure often changes significantly from one healthcare visit to another, there may a problem.
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.
You're using the wrong-sized cuff
The most common error when using indirect blood pressure measuring equipment is using an incorrectly sized cuff. A BP cuff that is too large will give falsely low readings, while an overly small cuff will provide readings that are falsely high.
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.
Most healthy individuals have variations in their blood pressure — from minute to minute and hour to hour. These fluctuations generally happen within a normal range. But when blood pressure regularly spikes higher than normal, it's a sign that something isn't right.
Your blood pressure regularly rises and falls, but if your blood pressure changes too much within minutes, this may be one of the signs of labile hypertension.
Regular fluctuations in blood pressure can increase the risk of : a heart attack. a stroke. heart failure.
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. Write down the average of the second and third reading.
Abstract. Guidelines recommend 1 to 2 minutes between repeated, automated office-based blood pressure (AOBP) measures, which is a barrier to broader adoption.
“It's actually quite normal to have variation in blood pressure readings, even within a few minutes,” says Marjorie Willett, nurse practitioner at Aurora Lakeland Medical Center. “Factors that may create changes include physical activity, emotion, diet (especially salt and alcohol intake), and sleep deprivation.”
In the American Heart Association BP measurement guideline [12], the following statement was described without any citation: 'three readings should be taken in succession, separated by at least 1 min. The first is typically the highest, and the average should be used as the blood pressure reading.
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 is usually lower at night while sleeping.
When it comes to blood pressure, one reading may not be enough. Forty-six percent of Americans have high blood pressure, but studies show when it's taken twice at your doctor's office - with at least one minute in between - the second reading is typically lower and a more accurate measurement.
Conclusions. Single-arm measurements, compared to double-arm measurements, may underestimate the prevalence of hypertension. However, if double-arm measurements are unavailable, right arm is preferred for measurement of BP, especially in women.
Your blood pressure should be checked in the morning, about an hour after you wake up, and in the evening, about an hour before you go to sleep, using the same arm each time. Taking 3 consecutive measurements (about 1 minute apart) will provide a more accurate understanding of your "true" blood pressure.
“It's normal, of course, for a person's blood pressure to rise and fall from minute to minute with changes in posture, exercise, stress, or sleep,” says Mercado. “As a result, health care professionals consider an average reading more important than that at any one time.”
To take an average simply add the two readings together and divide by two. Divide by three if you use all three readings. Ignore the first day's readings altogether, because they might not be accurate as you're not familiar with your monitor yet.
There are two numbers involved in a blood pressure reading. The first is known as "systolic," and it measures the pressure when the heart muscle contracts. The second number is known as "diastolic," and it's the measurement of the pressure when the heart muscle is at rest.
"The two numbers should never be more than 60 points apart," Dr. Elefteriades says. "Being 70 points apart suggests there could be a deeper problem, such as a leaky valve" — a condition in which bloodflow through the heart becomes more turbulent than normal.
Surges of anxiety can cause blood pressure spikes, but these are typically temporary. Over time, however, chronic anxiety can begin to have an adverse effect on someone's baseline blood pressure. We understand your desire to manage each of these conditions without the use of medication.
The less you sleep, the higher your blood pressure may go. People who sleep six hours or less may have steeper increases in blood pressure. If you already have high blood pressure, not sleeping well may make your blood pressure worse.
And does dehydration cause high blood pressure? Drinking water can help normalize your blood pressure but doesn't necessarily lower your blood pressure unless you are dehydrated. Because your blood is made up of 90% water, the overall volume will decrease when you are dehydrated.
Your blood pressure is strongly influenced by your body's circadian rhythms, including your natural sleep cycle. Your circadian rhythm is connected to the master clock in your brain which regulates your body function throughout the day.
