What Do The Readings Mean
As a general guide:
140/90mmHg or over you may have high blood pressureMost doctors use 140/90mmHg as the cut off for point for diagnosing high blood pressure . This is the point where your risk of serious health problems goes up. They might prescribe medications and advise you to make changes to your lifestyle to bring your blood pressure down. 120/80mmHg up to 140/90mmHg pre-high blood pressureAlso called high-normal blood pressure. This is not high blood pressure, but it is a little higher than it should be and means you could go on to develop high blood pressure. See how you can make healthy changes to your lifestyle to lower it. 90/60mmHg up to 120/80mmHg ideal blood pressureAlso called normal blood pressure. Your blood pressure reading is healthy. At this level you have a much lower risk of heart disease and stroke. Following a healthy lifestyle will help you to keep it in the healthy range. 90/60mmHg or lower you may have low blood pressureLow blood pressure usually isnt a problem, but it can sometimes make you feel faint or dizzy or could be a sign of another health problem.
The video below explains how your blood pressure numbers are linked to the risk of stroke and other disease.
Symptoms And Causes Of Low Blood Pressure
Many different conditions and situations can cause low blood pressure, from standing up too fast to being pregnant. Sometimes, low blood pressure is linked to an underlying problem. Thats why its important to see your doctor right away if you experience the signs of low blood pressure.
Symptoms of low blood pressure can include:
- Dizziness
- Fatigue
- Depression
Low blood pressure can be a sign of serious heart, endocrine or neurological conditions. If left untreated, the brain and other vital organs do not get the oxygen and nutrients they need. In extreme cases, this can cause shock, a life-threatening condition.
If you show signs of low blood pressure, your doctor will conduct an exam and may perform tests to determine whats causing the condition. Low blood pressure can occur with many other conditions.
Some causes of low blood pressure are:
Normal Blood Pressure For Men And Women By Age
A normal blood pressure reading indicates that the heart and blood vessels are not working too hard pushing blood and that the blood is not exerting too much pressure on the walls of the vessels, says Aseem Desai, M.D., a cardiologist at Providence Mission Hospital in Southern California. Recent data from the American Heart Association suggests the optimal normal reading for adults over 20 is lower than 120/80 mmHgVirani S, et al. Heart disease and stroke statistics 2021 update . American Heart Association Journal. 2021 143:e254-e743. .
Dr. Desai notes blood pressure can vary depending on a persons age, gender, race and ethnicity, but it should still fall within the general normal range. While numbers lower than 120/80 are generally considered normal, Dr. Desai adds, The target blood pressure for treatment varies depending on age and associated co-morbidities .
Previously, guidance for normal blood pressure for adults varied by gender and specific age, but new data states normal blood pressure for adults as a collective is less than 120/80 mmHgHigh Blood Pressure Symptoms and Causes. Centers for Disease Control and Prevention. Accessed 7/16/2021. .
When it comes to race and ethnicity, Dr. Desai says certain groups have a higher rate of hypertension. Non-Hispanic Black people have a significantly higher rate of hypertension compared to non-Hispanic white people, and Hispanics and non-Hispanic Asians have lower rates than the first two, he says.

How To Lower Blood Pressure
If youâre over 70 and have been told that your blood pressure is too high, donât let the conditionâs lack of symptoms keep you from working to get it into a healthy range. Make it a point to:
Review all your medications with your doctor.âMany people will need medication to manage their blood pressure,â Andromalos says. But be sure to tell your doctor about all other prescriptions you may have and any over-the-counter medications that you take, such as non-steroidal anti-inflammatory drugs or decongestants because they can raise your blood pressure, Dr. Vaishnava says.
Move more. Regular, moderate exercise can help you lower your blood pressure, the Mayo Clinic states. Find an activity you enjoy so that youâll stick with it cycling, walking, swimming or dancing, for instance. Strength training and high intensity interval training also can help lower your blood pressure.
Lose weight. The higher your body mass, the harder your heart has to work to pump critical blood. Losing even a small amount of weight can help lower your blood pressure, the Mayo Clinic states.
Low Blood Pressure In Elderly People: The Vital Facts You Should Know
Most people are aware that high blood pressure in seniors can lead to serious medical issues, but low blood pressure in elderly individuals gets far less attention. However, blood pressure that drops too low can have equally serious effects on your health. It’s important to know the facts so that you can take proper care of yourself.
A low blood pressure reading is not necessarily cause for panic. While high blood pressure is harmful even if you don’t know you have it, low blood pressure is generally not a problem unless you start experiencing symptoms like dizziness or blurred vision. If that happens, you need to take action. Symptomatic low blood pressure in the elderly can be very dangerous because it raises the risk of a fall. At its most extreme, it can lead to shock and even death.
This article explains the basic facts about blood pressure, including how it’s measured and what the measurements mean. It also describes common symptoms of low blood pressure and outlines a variety of factors that can cause such a condition. And it provides information about different ways that low blood pressure in older adults can be treated or managed.

Causes Of Low Blood Pressure
Your blood pressure can vary depending on the time of day. It gradually increases throughout the day.
What you’re doing and how you’re feeling can also affect it.
There are many possible causes of low blood pressure. It may be low because you’re fit and healthy, or you may have inherited it from your parents.
Some people develop low blood pressure as they get older.
It can also be caused by:
- being pregnant
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.

How Do You Treat Low Blood Pressure
When people are otherwise healthy and low blood pressure doesnt cause symptoms, no treatment is necessary. Even if symptoms occur occasionally or are mild, doctors may not recommend treatment. This is because low blood pressure is generally a healthy thing for your heart.
When people have concerning symptoms, treatment will depend on the cause. If medications are causing the problem, your doctor may adjust the dose or switch to another drug. For other underlying causes, treating them may help resolve your symptoms.
Serious Injuries And Shock
Low blood pressure can also be caused by serious injuries or burns, particularly if you have lost a lot of blood. This can mean that there is less blood being pumped around your body. Low blood pressure can also occur if you go into shock after having a serious injury.
Other kinds of shock are described below.
Anaphylactic shock
Anaphylactic shock, or anaphylaxis, is caused by an allergic reaction to something – for example, a wasp sting or a peanut. During an allergic reaction, your body produces a large amount of a chemical called histamine, which causes your blood vessels to widen and leads to a sudden, severe drop in blood pressure.
Cardiogenic shock
Cardiogenic shock occurs when your heart cannot supply enough blood to your body, so your blood pressure drops. This can happen during a heart attack.

What Can I Do For Myself
There are other things you can do for yourself to help with your symptoms.
- Wear supportive elastic stockings . They put extra pressure on your legs which helps to improve circulation and raise your blood pressure. For some people this can be enough, but speak to your GP first because they arent suitable for everyone.
- Stand up slowly from sitting or lying down. You can try other simple movements to get the blood flowing before you stand up, such as straightening and bending your legs.
- Avoid standing for long periods of time.
- Drink enough water throughout the day, around 2 litres, so you dont get dehydrated.
- Eat little and often throughout the day. This avoids low blood pressure after eating.

About Low Blood Pressure
The heart pumps a constant supply of blood around the body. The blood flows through different networks in the body, for example, arteries, veins and capillaries. Blood pressure is a measure of the force of the blood on the walls of the arteries as the blood flows through them.
It’s measured in millimetres of mercury and recorded as two measurements:
- systolic pressure the pressure when your heart beats and squeezes blood into your arteries
- diastolic pressure the pressure when your heart rests between beats
For example, if your systolic blood pressure is 120mmHg and your diastolic blood pressure is 80mmHg, your blood pressure is 120 over 80, which is commonly written as 120/80.
Normal blood pressure is between 90/60 and 140/90. If you have a sustained reading of 140/90 or more, you have high blood pressure . This puts you at greater risk of developing serious health conditions, such as heart attack or stroke.
People with a blood pressure reading under 90/60 are usually regarded as having low blood pressure.

Blood Pressure Monitor Vs Blood Pressure Cuff
Blood pressure monitor and blood pressure cuff are two phrases often used to describe the same blood pressure measurement tool. The blood pressure cuff is the element that wraps around either the upper arm, wrist or finger to measure blood pressure. The blood pressure monitor is the element in charge of inflating and deflating the cuff, as well as providing your blood pressure reading on an easy-to-read display.
Most experts recommend using a blood pressure monitor with an upper arm blood pressure cuff for at-home readings because they tend to be more accurate than wrist cuffs and finger cuffs.
New Findings Focus On Diastolic Blood Pressurethe Second Number In Your Blood Pressure Reading

Of the two numbers that make up your blood pressure reading, the first one typically gets more attention. That’s because as people age, their arteries lose their elasticity, and the inner walls are more likely to accumulate cholesterol-laden plaque. These factors tend to raise systolic blood pressure, a measure of the pressure inside the arteries when the heart contracts to pump blood throughout the body.
Current guidelines suggest that most people should aim for a systolic blood pressure reading of 140 millimeters of mercury or lower. But last year, a widely publicized clinical trial suggested that a target of 120 mm Hg could further reduce the dangers associated with high blood pressure .
Yet reaching that lower target required an average of three blood pressure medications, which resulted in more side effects. Now, two recent observational studies highlight some concerns about blood pressure that’s too low, particularly with regard to diastolic blood pressure. Diastolic blood pressure represents the pressure between beats when the heart relaxes.

Checking Blood Pressure At Home
Keeping track of blood pressure at home is important for many people, especially if you have high blood pressure. This helps you and your doctor find out if your treatment is working.
Your doctor may also suggest that you check your pressure at home if they think you may have white coat hypertension. Its a real condition. The stress of being in a doctors office raises your blood pressure, but when youre home, its normal.
Ask your doctor to recommend an easy-to-use home blood pressure monitor. Make sure the cuff fits properly. If your arm is too big for the cuff, the reading may be higher than your blood pressure really is. Ask your doctor for a larger cuff or make sure you buy a home monitor with a cuff that fits you.
You also can use a wrist blood pressure monitor, but they often arent as accurate. Follow the directions that come with the device to make sure you are using it correctly.
No matter which type of blood pressure monitor you have, its a good idea to take it to your doctors office. You can compare its reading to the numbers your doctor gets. Avoid caffeine, cigarettes, and exercise for at least 30 minutes before the test.
When you take your blood pressure at home, sit up straight in a chair and put both feet on the floor. Ask your doctor or nurse to show you the right way to position your arm so you get accurate readings.
How Blood Pressure Is Measured And What The Readings Mean
Blood pressure is expressed as two numbers, with one over the other. The first, or top, number is the systolic blood pressure. This indicates the amount of pressure your blood exerts against the walls of your arteries when your heart contracts. The second, or bottom, number is the diastolic pressure, which refers to the amount of pressure in your arteries when your heart refills between beats.
Your healthcare provider typically measures your blood pressure using a stethoscope and an inflatable cuff that wraps around your upper arm. The cuff is inflated until it is tight enough to stop the blood from flowing, then it is slowly deflated. Through the stethoscope, your doctor or nurse will hear the whooshing sound of the blood returning this is the systolic pressure. The moment the whooshing sound disappears marks the diastolic pressure.
The commonly accepted ideal blood pressure for adults is 120/80 mm Hg or lower. But since blood pressure naturally rises with age, your BP might be higher than that without any cause for concern. For instance, according to a chart from Disabled World, a normal blood pressure reading for an 80-year-old woman could be 134/84 mm Hg.
So, what is considered low blood pressure in elderly people? Typically, the low blood pressure range is anything below 90/60 mm Hg. This is called hypotension. The Disabled World chart shows that a dangerous blood pressure level is 50/33 mm Hg.

Average Blood Pressure By Age
As you get older, your blood vessels tend to become stiffer and plaque can build up in them, which can raise your blood pressure. If your blood pressure becomes too high, you’re at a greater risk for heart disease, strokes, and more.
In 2015, the average blood pressure worldwide was 127/79 mm Hg in men, and 122/77 mm Hg in women, according to a study analysis published in Lancet.
When researchers for the National Center for Health Statistics looked at average blood pressure in U.S. adults between 2001 and 2008, the average reading was 122/71 mm Hg. The breakout was 124/72 mm Hg for men, and 121/70 mm Hg in women. It rose by age and was significantly higher in Black people.
The researchers found the following breakdown by age, sex, and race or ethnicity:
