Taking Your Pulse Versus Checking Your Blood Pressure
While both are indications of health, blood pressure and heart rate are two separate measurements. Learn more about the difference between blood pressure and heart rate.
Systolic is less than 120 and my diastolic is less than 80
Great job! Your blood pressure is normal. To keep your readings in this range, stick with heart-healthy habits like following a balanced diet and getting regular exercise.
Systolic is 120 129 and my diastolic is less than 80
The good news is that you dont have high blood pressure. However, your numbers fall within the Elevated category, making you more likely to develop high blood pressure unless you take action to control it. Ready to make some small changes that have big impacts? Healthy lifestyle choices are a great place to start.
Systolic is 130 139 or my diastolic is 80 89
You are in the first stage of hypertension, but there are actions you can take to get your blood pressure under control. Your doctor will speak to you about small changes that can make a big difference and other BP Raisers. In addition, monitoring blood pressure outside of the doctors office is important for BP control.
Systolic is 140 or higher or my diastolic is 90 or higher
Systolic is higher than 180 and/or my diastolic is higher than 120

Risks Of High Blood Pressure
If your blood pressure is too high, it puts extra strain on your blood vessels, heart and other organs, such as the brain, kidneys and eyes.
Persistent high blood pressure can increase your risk of a number of serious and potentially life-threatening health conditions, such as:
- have a relative with high blood pressure
- are of black African or black Caribbean descent
- live in a deprived area
Making healthy lifestyle changes can sometimes help reduce your chances of getting high blood pressure and help lower your blood pressure if it’s already high.
Check Your Blood Pressure At Home
The new guidelines note that blood pressure should be measured on a regular basis and encourage people to use home blood pressure monitors. Monitors can range from $40 to $100 on average, but your insurance may cover part or all of the cost. Measure your blood pressure a few times a week and see your doctor if you notice any significant changes. Here are some tips on how to choose and use a monitor.
Choosing
- Select a monitor that goes around your upper arm. Wrist and finger monitors are not as precise.
- Select an automated monitor, which has a cuff that inflates itself.
- Look for a digital readout that is large and bright enough to see clearly.
- Consider a monitor that also plugs into your smartphone to transfer the readings to an app, which then creates a graph of your progress. Some devices can send readings wirelessly to your phone.

Learn more about ways to manage and prevent high blood pressure.
In addition to making positive lifestyle changes, some people with high blood pressure need to take medicine to manage their blood pressure. Learn more about medicines for high blood pressure.
Talk with your health care team right away if you think you have high blood pressure or if youve been told you have high blood pressure but do not have it under control.
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:
| Blood Pressure by Age |

Mean Arterial Pressure Significance
As mentioned earlier, a normal range for mean arterial pressure is 70 to 110 mm Hg. A mean arterial pressure in the high range could be an indication that the heart has to work much harder than it should. This is causing stress on the heart. High MAP can result in advanced heart disease, blood clots, heart attack, and stroke. When high mean arterial pressure is ongoing, heart muscles will enlarge and grow thicker, and jeopardize life expectancy. When MAP goes up quickly in a short period of time, organs can fail. A mean arterial pressure in the high range isnt the only concern though, low is also problematic.
Low MAP can also be fatal if left untreated. Pressure readings less than 60 mm Hg must be addressed. In this case, when organs are not getting the blood they need, you can go into shock and organs can fail. Low MAP can be caused by sepsis, hemorrhaging, stroke, or some sort of trauma.
Here are some situations where perfusion of organs might come into play and impact MAP:
- Head injuries
- Abdominal aneurysm
High Blood Pressure Categories
You can divide high blood pressure into five categories, according to guidelines from the American College of Cardiology:
- Normal: Normal blood pressure in adults is any blood pressure below 120/80.
- Elevated: In adults, elevated blood pressure is a systolic reading of 120-129 and a diastolic reading below 80.
- Hypertension stage I: This stage includes blood pressures ranges of 130-139 or 80-89 .
- Hypertension stage II: This stage includes blood pressures ranges above 140 or above 90 .
- Hypertensive crisis: Severely elevated blood pressure is defined as greater than 180 and/or 120 and associated with new or worsening organ damage.

Diagnosing High Or Low Blood Pressure
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.

What Diet Helps Control High Blood Pressure
- Eat foods that are lower in fat, salt and calories, such as skim or 1% milk, fresh vegetables and fruits, and whole grain rice, and pasta.
- Use flavorings, spices and herbs to make foods tasty without using salt. The optimal recommendation for salt in your diet is to have less than 1500 milligrams of sodium a day. Don’t forget that most restaurant foods and many processed and frozen foods contain high levels of salt. Use herbs and spices that do not contain salt in recipes to flavor your food do not add salt at the table.
- Avoid or cut down on butter and margarine, regular salad dressings, fatty meats, whole milk dairy products, fried foods, processed foods or fast foods, and salted snacks.
- Ask your provider if you should increase potassium in your diet Discuss the Dietary Approaches to Stop Hypertension diet with your provider. The DASH diet emphasizes adding fruits, vegetables, and whole grains to your diet while reducing the amount of sodium. Since it is rich in fruits and vegetables, which are naturally lower in sodium than many other foods, the DASH diet makes it easier to eat less salt and sodium.

What Causes Low Blood Pressure
The cause of low blood pressure isn’t always clear. It may be associated with the following:
- Pregnancy
- Some prescription medicines such as for high blood pressure, depression or Parkinsonâs disease
- Heart failure
- Heart arrhythmias
- Widening, or dilation, of the blood vessels
- Severe dehydration from vomiting, diarrhea, or fever
- A reaction to medication or alcohol
- A severe allergic reaction called anaphylaxis that causes an irregular heartbeat
Who Gets Postural Hypotension?
Postural hypotension, which is low blood pressure when standing up suddenly, can happen to anyone for a variety of reasons, such as dehydration, lack of food, or being overly fatigued. It can also be influenced by genetic make-up, aging, medication, dietary and psychological factors, and acute triggers, such as infection and allergy.
Postural hypotension occurs most frequently in people who are taking drugs to control high blood pressure . It can also be related to pregnancy, strong emotions, hardening of the arteries , or diabetes. The elderly are particularly affected, especially those who have high blood pressure or autonomic nervous system dysfunction.
Hypotension after meals is a common cause of dizziness and falls after eating. This is most common after large meals containing a lot of carbohydrates. Itâs believed to be caused by blood pooling into the vessels of the stomach and intestines.
Common causes of naturally occurring postural hypotension include:
Associations Between Blood Pressure And Brainage
Associations between BrainAGE and mean, diastolic and systolic BP are presented in Figure 2. None of the analyses revealed an interaction between BP and Time-in-Study or a random effect of blood pressure on BrainAGE indicating that a change in BrainAGE over time was not predicted by baseline BP or by a change of BP over time . Therefore, only fixed effects are reported below.

Which Number Is Most Important
Both. Having a high number in either systolic or diastolic pressure can lead to a diagnosis of hypertension . However, systolic pressure tends to get more attention because high systolic blood pressure is a risk factor for cardiovascular disease for people over 50, and it can indicate major cardiac events.
Also note: Heart rate and blood pressure are not the same, and they can indicate different issues. The American Heart Association reports that blood pressure measures the force that blood moves through blood vessels, and heart rate measures the amount of times your heart beats per minute. Having a healthy heart rate does not necessarily mean your blood pressure is in a healthy range. Both measurements are important, but one does not replace the other.
Signs And Symptoms Of High Blood Pressure
High blood pressure may not have any symptoms and so hypertension has been labeled “the silent killer.” Longstanding high blood pressure can lead to multiple complications including heart attack, kidney disease, or stroke.
Some people experience symptoms with their high blood pressure. These symptoms include:
- Headache
- The Feeling of pulsations in the neck or head
- Nausea

Habits For Promoting Healthy Blood Pressure
Blood pressure is greatly influenced by lifestyle, so most healthy people can properly manage blood pressure without medical intervention.
Keeping body weight within a normal range, eating a heart-healthy diet, decreasing mental stress and having a regular aerobic exercise routine can have a profound effect on blood pressure, Kazemi said.
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 Are The Causes Of High Blood Pressure
Elevated blood pressure increases your risk of chronic high blood pressure as you age. Taking steps to manage your blood pressure helps decrease this risk.
There are also some health conditions that increase your risks of chronic high blood pressure, including obesity and diabetes. Other causes include:
- Genetics/family history
- Lack of exercise
- Alcohol or tobacco abuse
As adults age, their odds of high blood pressure increase, with 90% of Americans forecasted to develop high blood pressure in their lifetimes. Black people tend to develop high blood pressure more often and earlier in life compared to white people. Hispanics, Asians, American Indians, and Pacific Islanders also stand an increased risk of high blood pressure compared to other ethnicities.
How Can I Be More Active
- Check first with your healthcare provider before increasing your physical activity. Ask your provider what type and amount of exercise is right for you.
- Choose aerobic activities such as walking, biking or swimming.
- Start slowly and increase activity gradually. Aim for a regular routine of activity 5 times a week for 30 to 45 minutes each session.

Blood Pressure Reading Chart
Below is a blood pressure reading chart for you.
*Remember that the larger figure in your reading represents the systolic value the smaller figure represents your diastolic value. Systolic is the measurement of pressure when the heart is beating. Diastolic is the measurement of pressure when the heart is resting.
Achieving Blood Pressure Goals
During the preparation of the Sixth Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure , the investigators focused on the goal of reducing morbidity and mortality caused by hypertension-related events, that is, cardiovascular disease, cerebrovascular disease, and renal failure. We concluded that more stringent blood pressure goals and more aggressive approaches to reducing blood pressure were needed to achieve better control of hypertension worldwide. An SBP < 140 mm Hg and a DBP < 90 mm Hg was proposed as the goal for most patients. For patients with diabetes, even lower goals for optimal blood pressure were recommended . The overriding message of the JNC VI report was to establish an appropriate blood pressure goal and work to meet that goal through aggressive treatment with multiple agents, if needed.

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.
