Do I Have High Blood Pressure

Good Question: What Do Your Blood Pressure Numbers Mean?

Anyone can have high blood pressure. Some medical conditions, such as metabolic syndrome, kidney disease, and thyroid problems, can cause high blood pressure. Some people have a greater chance of having it because of things they can’t change. These are:

  • Age. The chance of having high blood pressure increases as you get older, especially isolated systolic hypertension.
  • Gender. Before age 55, men have a greater chance of having high blood pressure. Women are more likely to have high blood pressure after menopause.
  • Family history. High blood pressure tends to run in some families.
  • Race. African Americans are at increased risk for high blood pressure.

High blood pressure often has no signs or symptoms, but routine checks of your blood pressure will help detect increasing levels. If your blood pressure reading is high at two or more check-ups, the doctor may also ask you to measure your blood pressure at home.

There are important considerations for older adults in deciding whether to start treatment for high blood pressure if it is above 130/80, including other health conditions and overall fitness. Your doctor may work with you to find a blood pressure target that is best for your well-being and may suggest exercise, changes in your diet, and medications.

How Is High Blood Pressure Diagnosed

High blood pressure is diagnosed with a blood pressure monitor. This is a common test for all doctor visits. A nurse will place a band around your arm. The band is attached to a small pump and a meter. He or she will squeeze the pump. It will feel tight around your arm. Then he or she will stop and watch the meter. This provides the nurse with 2 numbers that make up your blood pressure. The top number is your systolic reading . The bottom number is your diastolic reading . You may also hear the doctor or nurse say a blood pressure is 120 over 80.

  • Normal blood pressure is less than 120 on top and less than 80 on the bottom.
  • Prehypertension levels are 120-139 on top and 80-89 on the bottom.
  • High blood pressure, stage 1 is 140-159 on top and 90-99 on the bottom.
  • High blood pressure, stage 2 is 160 or higher on top and 100 and over on the bottom.

The higher your blood pressure is, the more often you need to have it checked. After age 18, have your blood pressure checked at least once every two years. Do it more often if you have had high blood pressure in the past.

The Basics Of Blood Pressure

A blood pressure reading is made up of two numbers expressed as a fraction. The top number, or systolic pressure, measures how much pressure is in the arteries when the heart contracts. The bottom number, or diastolic pressure, measures the blood pressure between beats.

When your heart pumps, all that blood rushes and fills your arteries, Baker said. Its just like plumbing: if youre pumping more water into the system, the pressure inside the plumbing goes up. Thats your systolic reading. When the heart relaxes and fills, the reading falls and you get the lower number, or your diastolic reading.

Top 10 Best Blood Pressure Monitors Buying Guide and ...

The diastolic reading, or the bottom number, is the pressure in the arteries when the heart rests between beats. This is the time when the heart fills with blood and gets oxygen.

This is what your diastolic blood pressure number means:

  • Normal: Lower than 80
  • Stage 2 hypertension: 90 or more
  • Hypertensive crisis: 120 or more. Call 911.

Our chart below has more details.

Even if your diastolic number is normal , you can have elevated blood pressure if the systolic reading is 120-129.

What Are The Symptoms Of High Blood Pressure

What Do the Blood Pressure Numbers Mean and What Is a Target Blood Pressure?

Most people who have high blood pressure do not have symptoms. This is why its sometimes called the silent killer. It is very important to have your blood pressure checked regularly.

Some people experience headaches, nosebleeds, or shortness of breath with high blood pressure. However, those symptoms can mimic many other things . Usually, these symptoms occur once blood pressure has reached a dangerously high level over a period of time.

Medicines For High Blood Pressure

Why are different people given different medicines?

People respond differently to blood pressure medicines. A number of things can affect how you respond to each medicine, including your ethnic background, age and how much salt you eat. It can take some trial and error to find the medicine or combination of medicines that works best for you.

Younger, non-black people tend to respond slightly better to ACE inhibitors and angiotensin receptor blockers. Older people and those of African or Caribbean origin tend to respond better to calcium-channel blockers and thiazide diuretics.

These will usually be the first medicines youre offered, aiming to keep the number of medicines needed to a minimum. Read more about .

Should I be taking aspirin as well?

If you have high blood pressure, your doctor might recommend that you take aspirin if you are at a higher risk of heart attacks or strokes, for example, if you have had an ischaemic stroke caused by a blood clot or heart attack in the past. This is because aspirin thins your blood and prevents blood clots from forming.

Do not start taking aspirin regularly unless your doctor advsises you to because aspirinâs ability to prevent clots can raise the risk of bleeding from the stomach and intestines, it might also be linked to a higher risk of strokes caused by burst blood vessels.

What Does A Blood Pressure Reading Look Like

When you have your , you will be given two numbers, a top number and a bottom number.

  • Systolic blood pressure. This is the first, or top, number. This is the highest level your blood pressure reaches when your heart beats, forcing blood around your body.
  • Diastolic blood pressure. The second number, or bottom number, is the lowest level your blood pressure reaches as your heart relaxes between beats.

Blood pressure is measured in millimetres of mercury . If the first number is 120 and the second number is 80, this would be written as 120/80mmHg, and youd call it 120 over 80.

Doctors: Beware Of Low Diastolic Blood Pressure When Treating Hypertension

High blood pressure: Like an over
  • Low diastolic blood pressure linked to heart damage. â
  • Physicians, be aware of not dropping the bottom blood pressure number. â
  • Overtreated high blood pressure could be dangerous in certain patients. â

The researchers caution that their findings cannot prove that very low diastolic blood pressure a measure of pressure in arteries between heartbeats when the heart is resting and also the lower number in a blood pressure reading directly causes heart damage, only that there appears to be a statistically significant increase in heart damage risk among those with the lowest levels of diastolic blood pressure.

A summary of the findings was published Aug. 30 in the Journal of the American College of Cardiology and coincides with the release of a similar analysis at the European Society of Cardiology Meeting by physicians from Hôpital Bichat in Paris, France.

Released last fall, the SPRINT trial showed protective cardiovascular benefits to patients when physicians aggressively treated high blood pressure down to 120/80 millimeters of mercury, with a primary emphasis on keeping systolic pressure the top number, representing arterial pressure when the heart is pumping at no more than 120.

Researchers followed the participants for 21 years in a series of five visits, with the last check-in in 2013. Each visit included blood pressure measurement, and several included blood testing.

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.

High Systolic Blood Pressure Stage 1

A high systolic blood pressure stage 1 reading is when systolic blood pressure is between 130-139 mmHg, regardless of the diastolic number 3.

Doctors will recommend lifestyle changes and may consider prescribing medicine based on the risk of cardiovascular disease.

How Does Your Circulatory System Work

Your circulatory system is an amazing, complicated and efficient way your body delivers oxygen and nutrients to every part of your body. Following is a simplified version of how it works.

Your heart consists of four chambers: the left and right atrium and the left and right ventricle . When the heart relaxes, blood flows from the atria to the ventricles. Then the ventricles pump, sending oxygen-rich blood to the arteries.

The arteries send blood throughout your bodys network of capillaries, where it releases nutrients. The blood then gathers carbon dioxide and returns to the heart through the veins where the process starts over again.

Which Blood Pressure Number Is Important

What do the numbers mean on Blood Pressure? | Gina Eubank

Q.When I am monitoring my blood pressure, which number is most important top, bottom, or both?

A. 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.

Systolic pressure reflects the force produced by the heart when it pumps blood out to the body, while diastolic blood pressure is the pressure in your blood vessels when the heart is at rest.

Over the years, research has found that both numbers are equally important in monitoring heart health. However, most studies show a greater risk of stroke and heart disease related to higher systolic pressures compared with elevated diastolic pressures. That’s especially true in people ages 50 and older, which is why doctors tend to monitor the top number more closely. The reason for the difference in risk may be related to the force put on the arteries when blood rushes out of the heart.

The American Heart Association now defines high blood pressure as 130/80 mm Hg or higher. The new guidelines recommend you check your blood pressure often, ideally with a home monitor, to help your doctor determine if you need to make lifestyle changes, begin medication, or alter your current therapy.

Isolated Systolic Hypertension In The Elderly

Systolic blood pressure rises steadily with age. This is due to the increasing stiffness of large arteries, long-term plaque buildup and an increased incidence of cardiovascular disease.

According to a recent study, persons who reached age 65, if they lived another 20 years, had a 90% lifetime risk of developing isolated systolic hypertension or high blood pressure 5.

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.” It’s a real condition. The stress of being in a doctor’s office raises your blood pressure, but when you’re home, it’s 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 aren’t 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, it’s a good idea to take it to your doctor’s 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.

What Do The Numbers Mean

What do the blood pressure noumbers Mean

When a healthcare professional takes your blood pressure, its expressed as a measurement with two numbers, one number on top and one on the bottom , like a fraction. For example, 120/80 mm Hg.

Blood pressure is measured in millimeters of mercury. Thats what the mm/Hg stands for. Heres what the numbers mean:

  • Your systolic pressure is the pressure of the blood in your arteries when your heart contracts or beats.
  • Your diastolic pressure is the pressure of the blood in your arteries between beats, when your heart relaxes.

Both numbers are important in determining the state of your heart health.

Numbers greater than the ideal range may be a sign that your heart is working too hard to pump blood to the rest of your body.

For a normal reading, your blood pressure needs to show:

  • a systolic pressure thats above 90 mm Hg and less than 120 mm Hg, and
  • a diastolic pressure thats between 60 mm Hg and less than 80 mm Hg

The American Heart Association considers blood pressure to be within the normal range when both your systolic and diastolic numbers are in these ranges.

If youre in the normal range, no medical intervention is needed. However, its important to maintain a healthy lifestyle and moderate weight to help prevent high blood pressure from developing.

You may need to be even more mindful of your lifestyle if high blood pressure runs in your family.
