What Is Normal Blood Pressure According To Age

What is a Normal Blood Pressure Reading?

Blood pressure is the pressure of the blood within the arteries. It is produced primarily by the contraction of the heart muscle. Its measurement is recorded by two numbers. The first is measured after the heart contracts and is highest. The second is measured before the heart contracts and the lowest. A blood pressure cuff is used to measure the pressure. Elevation of blood pressure is called “hypertension“.

The chart shows normal blood pressure according to age both male and female. Diastolic blood pressure and Systolic Blood Pressure are included in the chart.

What Is Normal Blood Pressure

For years we have been told that a normal blood pressure reading is 120/80 however, more and more doctors have now lowered these numbers to 115/75. Blood pressure is different for everyone as many factors can have an effect on the numbers.

Our blood pressure refers to the amount of force behind the blood as it hits the arterial walls. As the heart pumps the blood, an ideal pressure sees the blood push against the walls that are flexible enough to expand and retract easily. Over time, our age, diet, and physical activity play a role on the elasticity of our blood vessels. With a loss of flexibility due to hardening of the walls, the heart needs to work harder to push the blood.

These factors determine the blood pressure numbers. The systolic number is the top number, and it indicates the pressure as the heart beats or pushes the blood throughout the body. The diastolic number is the bottom number, and refers to the pressure in the arteries when the heart rests between beats. During this time, the heart receives oxygen as it fills with blood.

Which Number Is More Important

Typically, more attention is given to systolic blood pressure as a major risk factor for cardiovascular disease for people over 50. In most people, systolic blood pressure rises steadily with age due to the increasing stiffness of large arteries, long-term buildup of plaque and an increased incidence of cardiac and vascular disease.

However, either an elevated systolic or an elevated diastolic blood pressure reading may be used to make a diagnosis of high blood pressure. According to recent studies, the risk of death from ischemic heart disease and stroke doubles with every 20 mm Hg systolic or 10 mm Hg diastolic increase among people from age 40 to 89.

Making Sense of Blood Pressure Readings

Blood pressure ranges for adults are:

  • High: Systolic of 130 or above and/or diastolic of 80 or above
  • High Blood Pressure Stage 1: Systolic of 130-139 or diastolic of 80-89
  • High Blood Pressure Stage 2: Systolic of 140 or higher or diastolic 90 or higher
  • Elevated: Systolic between 120 and 129 and diastolic of 79 or below
  • Normal: Systolic of 119 or below and diastolic of 79 or below
  • Low: Systolic of less than 100 and/or diastolic of less than 60
  • Some people may have normal or asymptomatic blood pressures lower than 100/60
  • In people who have chronically elevated blood pressure , symptoms of low blood pressure may occur at readings above 100/60
  • Hypertensive crisis: Systolic of 180 or higher and/or diastolic of 120 or higher

    Higher than 120

    The normal blood pressure for adolescents 13 years or older is less than 120/80 mmHg.

    In younger children, the normal range for blood pressure is determined by the child’s sex, age, and height. The normal range is expressed as a percentile, similar to charts used to track children’s growth.

    Blood pressure is separated into three categories based upon the child’s blood pressure percentile:

    What Causes Low Blood Pressure

    There are many possible reasons for low blood pressure, according to both Dr. Wong and Dr. Desai, including:

    • Heart problems like heart failure or low heart rates
    • Endocrine problems, such as parathyroid disease, adrenal insufficiency or hypoglycemia
    • Dehydration
    • Side effects of medications for high blood pressure, prostatic hypertrophy, Parkinsons disease, depression and erectile dysfunction
    • Massive weight loss
    • Rapid heart rate

    Ambulatory Blood Pressure Monitoring

    In some cases, your doctor may recommend 24-hour or ambulatory blood pressure monitoring .

    This is where your blood pressure is tested automatically around every 30 minutes over a 24-hour period using a cuff attached to a portable device worn on your waist.

    ABPM can help to give a clear picture of how your blood pressure changes over the course of a day.

    You should continue with your normal daily activities during the test, although you must avoid getting the equipment wet.

    What Medications Are Used To Treat High Blood Pressure

    Four classes of high blood pressure medications are considered first line when starting treatment. Sometimes other medications are coupled with these first-line drugs to better control your high blood pressure. First-line drug pressure lowering medications are:

    • Angiotensin-converting enzyme inhibitors block the production the angiotensin II hormone, which the body naturally uses to control blood pressure. When angiotensin II is blocked, your blood vessels dont narrow. Examples: lisinopril , enalapril , captopril .
    • Angiotensin II receptor blockers block this same hormone from binding with receptors in the blood vessels. ARBs work the same way as ACE inhibitors to keep blood vessels from narrowing. Examples: metoprolol , valsartan , losartan .
    • Calcium channel blockers prevent calcium from entering the muscle cells of your heart and blood vessels, allowing these vessels to relax. Examples: amlodipine , nifedipine , diltiazem .
    • Diuretics flush excess sodium from your body, reducing the amount of fluid in your blood. Diuretics are often used with other high blood pressure medicines, sometimes in one combined pill. Examples: indapamide, hydrochlorothiazide, chlorothiazide.

    Low Blood Pressure Chart

    What is a normal blood pressure reading?

    Considering low blood pressure chart in context of women, for men, during pregnancy and by age

    Low blood pressure is defined as blood pressure that is below the normal expected for a person in a given environment. You may look at the blood pressure definition for a broader definition of blood pressure. The following low blood pressure chart is applicable to adult men and women. This is because both adult male and females are expected to have a similar normal blood pressure on average of 120/80mmHg.

    This chart in discussion here may not be efficiently applicable on children because infants and children specifically have significantly lower blood pressure compared to adult men and women.

    High blood pressure which is also known as hypertension is often presented with the aid of a high blood pressure chart showing the various stages of hypertension congruent with particular blood pressure numbers. Several challenges present when attempting to do the same for low blood pressure in the form of a low blood pressure chart.

    Chief among these challenges is the widely agreed and understood relativity of a low blood pressure condition. The chart above summarizes known data of low blood pressure readings in some individuals and accompanying symptoms of low blood pressure.

    What Does It Mean To Have Low Blood Pressure

    Generally, low blood pressure or hypotension means that your blood pressure falls under 90 mm Hg systolic and 60 mm Hg diastolic. However, this should be assessed on an individual basis.

    Some people have low blood pressure with no health problems, while others could have an underlying condition in need of treatment, according to the National Heart, Lung, and Blood Institute . Other factors that can lead to high blood pressure include:

    • Dehydration
    • Certain medications for anxiety, depression, pain, or surgery
    • Diuretics
    • Alcohol
    • Conditions like diabetes, heart failure, or an abnormal heart rhythm

    If you or someone else has low blood pressure and passes out, call 911 or seek medical attention immediately. Dangerous dips in blood pressure deprive organs of oxygen and can lead to shock, a medical emergency.

    If you have symptoms such as black stools, dizziness, blurred vision, chest pain, shortness of breath, or a fever above 101°F , call your doctor ASAP, according to MedlinePlus.

    Treatment for low blood pressure involves addressing the root cause such as taking medication for an underlying condition or adjusting your current treatment plan to avoid this side effect, says Dr. Wong.

    What Are The Treatments For Low Blood Pressure

    The treatments for low blood pressure depend on what caused the condition. Your doctor will work with you to address the cause of the hypotension. In severe cases of hypotension, your doctor may give you IV fluids to raise your blood pressure.

    Depending on a variety of factors, such as your age and the type of hypotension, your doctor may recommend one or more of the following: dietary changes, lifestyle changes and/or medications.

    To make dietary changes, your doctor might tell you to:

    • Stay hydrated by drinking more water throughout the day.
    • Drink less alcohol.
    • Increase your salt intake slightly because sodium raises blood pressure.
    • Eat smaller, healthy meals and limit carbohydrates.

    You can take several steps to avoid a sudden drop in blood pressure. Your doctor may recommend that you make the following lifestyle changes:

    • Wear compression stockings.
    • Get up slowly after youve been sitting or lying down.
    • Avoid standing for long periods of time.
    • Sit up and breathe deeply for a few minutes before getting out of bed.

    How To Take Blood Pressure

    You can take your blood pressure at home using a wrist blood pressure monitor or an upper arm cuff blood pressure monitor. Experts typically recommend upper arm cuffs because they are the most accurate. Upper arm cuffs can come with either a manual or digital monitor. Both work well, but if youre measuring your blood pressure on your own regularly, a digital one will likely be easiest to use correctly.

    To take your blood pressure accurately with a digital upper arm cuff, start by sitting quietly in an upright position for a few minutes, allowing your body a moment to relax. Be mindful to uncross your legs and ankles, as well as use comfortable support for your back.

    With the monitor sitting on a table in front of you, place your arm next to itat approximately heart leveland place the cuff around your bare upper arm about one inch above your elbow. Secure the cuff so that you can only slide a fingertip under the top edge.

    Next, simply turn on the monitor, press the start button, and take normal breaths as the cuff inflates and deflates, measuring your blood pressure and producing your reading on the screen.

    What Causes High Blood Pressure

    High blood pressure usually develops over time. It can happen because of unhealthy lifestyle choices, such as not getting enough regular physical activity. Certain health conditions, such as diabetes and having obesity, can also increase the risk for developing high blood pressure. High blood pressure can also happen during pregnancy.

    You can manage your blood pressure to lower your risk for serious health problems that may affect your heart, brain, kidneys, and eyes.

    Salt Intake And High Blood Pressure

    Reducing the amount of salt you eat can also help to manage or even avoid high blood pressure. To help reduce your salt intake:

    • Ensure your diet consists of wholefoods including vegetables, fruits, wholegrains, lean meat and poultry, fish and seafood, legumes, unsalted nuts and seeds.
    • Avoid packaged and processed foods that are high in salt. You cant see the salt in these foods, so you dont know how much salt you are having. Get into the habit of checking food labels.
    • Choose low-salt food where possible. If you cant find low-salt products, those with moderate amounts of salt are ok too. Another simple alternative is to look for labels with low salt, salt reduced or no added salt.
    • Avoid adding salt to cooking or at the table flavour meals with herbs and spices instead.

    What Exactly Is Blood Pressure

    “Blood pressure is the pressure that exists within our arteries and drives blood throughout our body,” says Dr. Del Conde Pozzi. At normal levels, your heart creates just enough blood pressure to pump blood to vital organs like your eyes and kidneys without damaging your arteries over time.

    If your blood pressure is elevated, though this hinders blood flow over time and can cause organ damage, hardening of your arteries, and plaque buildup within your arteries. These changes narrow and stiffen your arteries, increasing the risk of blood clots, heart disease, stroke, heart attack, and kidney disease, per the Centers for Disease Control & Prevention .

    What Do Blood Pressure Numbers Mean

    Understanding Blood Pressure Readings | Normal BP levels |

    Blood pressure is measured using two numbers:

    The first number, called systolic blood pressure, measures the pressure in your arteries when your heart beats.

    The second number, called diastolic blood pressure, measures the pressure in your arteries when your heart rests between beats.

    If the measurement reads 120 systolic and 80 diastolic, you would say, 120 over 80, or write, 120/80 mmHg.

    Get With The Guidelines

    In 2017, the American Heart Association, the American College of Cardiology and nine other health organizations published revised guidelines for blood pressure.

    They were updated “because research suggested that you can have complications from high blood pressure at lower levels than previously thought,” says Laura Andromalos, RD, CDE, nutrition program manager at Northwest Weight and Wellness Center in Everett, Washington, and a certified diabetes educator coach in the telehealth setting for Cecelia Health. “Previously, adults over 65 years old were considered to have high blood pressure at levels over 150/80 mmHg.”

    We now know that the ideal of 120/80 lowers the risks for both heart attacks and strokes, according to the American Heart Association. However, each person is unique, so at every age, it’s important to work with your doctor to be sure your numbers fall within a range that is ideal for you and your overall health, Dr. Vaishnava says.

    Home Blood Pressure Monitoring

    Blood pressure tests can also be carried out at home using your own digital blood pressure monitor.

    This can give a better reflection of your blood pressure, as being tested in somewhere like a GP surgery can make you feel anxious and can affect the result. It can also allow you to monitor your condition more easily in the long term.

    You can buy a variety of low-cost monitors so you can test your blood pressure at home or while you’re out and about.

    It’s important to make sure you use equipment that has been properly tested. The British Hypertension Society has information about validated blood pressure monitors you can buy.

    When To Take A Blood Pressure Reading

    Blood pressure can fluctuate on a daily basis due to myriad factors and its important to consider the source, Segal said. Things like stress, exercise, laughter, medication, caffeine, illness and sex can all contribute to pressure swings that are likely not a cause for concern.

    Even the time of day blood pressure is monitored can affect the numbers.

    When youre waking up, your blood pressure is on the lower level, Segal said.

    Meanwhile, a dramatic uptick may be seen if pressure is taken during the workday, in a high-stress environment or right after exercise. Those are not the best times to monitor.

    When done properly, the best readings to understand what a persons normal range is can be found at home, according to Segal.

    To keep fluctuations at a minimum, and get a better baseline reading, there are a few things to consider:

    • Make sure the home monitor fits well
    • Take the pressure right before eating or in the evening about 30 minutes after dinner when most people are least stressed
    • Avoid taking any medications first
    • Keep as calm as possible

    Segal finds that using an arm blood pressure cuff is more reliable than one that wraps around the wrist. When checking the pressure, the arm should be at the level of the heart.

    So, if youre lying down, the arm should be beside you and if youre sitting up, put your arm, lets say, on a desk, Segal said.

    Diagnosing High Or Low Blood Pressure

    Blood Pressure Chart &  Numbers (Normal Range, Systolic ...

    Only one of your numbers needs to be higher than it should be to be diagnosed with high blood pressure, and only one needs to be lower than it should be to be diagnosed with low blood pressure.

    So if your top number is over 140 or the bottom number is over 90, you may be diagnosed with high blood pressure, regardless of the other number. If your top number is under 90 or your bottom number is under 60, you may be diagnosed with low blood pressure. Use the chart to see where your numbers sit.

    If your top number is consistently higher than 140mmHg, but the bottom number is healthy – this is known as Isolated Systolic Hypertension. If the bottom number is consistently higher than 90mmHg but the top number is healthy – this is known as Isolated Diastolic Hypertension.

    Making sure your readings arent a one-off

    A single high reading doesnt necessarily mean you have high blood pressure, as many things can affect your blood pressure throughout the day, such as the temperature, when you last ate, and if youre feeling stressed.

    Your doctor or nurse will probably want to measure your blood pressure a number of times over a few weeks to make sure the reading wasnt just a one off and that your blood pressure stays high over time.
