What Is High Blood Pressure What Is Normal Blood Pressure
- High blood pressure is defined as high pressure in the arteries, which are the vessels that carry blood from the heart to the rest of the body.
- Blood pressure readings are given as two numbers:
- The systolic blood pressure equals the pressure in the arteries as the heart contracts.
- The diastolic pressure is the pressure in the arteries as the heart relaxes.
Causes And Risk Factors
You may be at an increased risk for high blood pressure if you smoke, areoverweight, eat a diet thats low on produce and fiber and/or high in fatand salt, drink alcohol to excess, live with chronic stress or dont getmuch physical activity. Some causes of hypertension cannot becontrolledincluding your genes and your race . Aging also plays a role. Even if you do not have hypertensionby age 55 to 65, your lifetime risk for developing it is a whopping 90percent.
In one Johns Hopkins study of 975 older women and men with hypertension,healthy lifestyle steps helped 40 percent stop taking blood pressuremedications. Other research has shown that lifestyle changes can lower therisk for hypertension in African-Americans and others at an increasedgenetic risk.
Eat Some Dark Chocolate
Yes, chocolate lovers: Dark chocolate has been shown to lower blood pressure.
But the dark chocolate should be 60 to 70 percent cacao. A review of studies on dark chocolate has found that eating one to two squares of dark chocolate per day may help lower the risk of heart disease by lowering blood pressure and inflammation.
The benefits are thought to come from the flavonoids present in chocolate with more cocoa solids. The flavonoids help dilate, or widen, your blood vessels .
Blood Pressure Checks During Pregnancy
If you are pregnant, you should have your blood pressure checked on a regular basis, even if it is not high.
Watching your blood pressure while you are pregnant reduces your risk of developing pregnancy-induced hypertension. This can lead to a serious condition called pre-eclampsia where there is a problem with the placenta .
What About Blood Pressure Thats Too Low
Low blood pressure is known as hypotension. In adults, a blood pressure reading of 90/60 mm Hg or below is often considered hypotension.
Hypotension can be dangerous because blood pressure thats too low doesnt supply your body and heart with enough oxygenated blood.
Some potential causes of hypotension can include:
- heart problems

How Common Is High Blood Pressure
High blood pressure is a common condition, it is estimated that 18% of adult men and 13% of adult women have high blood pressure but are not getting treatment for it.
In 90-95% of cases, there is no single identifiable reason for a rise in blood pressure. But all available evidence shows that lifestyle plays a significant role in regulating your blood pressure.
Risk factors for high blood pressure include:
- poor diet
- being overweight
- excessive alcohol consumption.
Also, for reasons not fully understood, people of Afro-Caribbean and South Asian origin are more likely to develop high blood pressure than other ethnic groups.
Why Is Hypertension An Important Issue In Low
The prevalence of hypertension varies across regions and country income groups. The WHO African Region has the highest prevalence of hypertension while the WHO Region of the Americas has the lowest prevalence of hypertension .
The number of adults with hypertension increased from 594 million in 1975 to 1.13 billion in 2015, with the increase seen largely in low- and middle-income countries. This increase is due mainly to a rise in hypertension risk factors in those populations.

Causes Of High Blood Pressure
Although the exact cause is unknown, certain conditions, traits or habits may raise your risk for the condition. These are known as risk factors and include:
Non-modifiable risk factors: These factors are irreversible and cannot be changed. The more of these risk factors you have, the greater your chance of developing HBP.
- Starting at age 18, ask your doctor for a blood pressure reading at least every two years. If you’re age 40 or older, or you’re 18 to 39 with a high risk of high blood pressure, ask your doctor for a blood pressure reading every year.
- Family history/Genetics
- African Americans and non-white Hispanic Americans are at higher risk for developing high blood pressure than any other group in the U.S.
Modifiable risk factors: These factors can be modified, treated or controlled through medications or lifestyle changes.
- Excessive alcohol consumption over many years.
- Little to no physical activity
- Excessive amounts of salt in diet that excess the recommended amounts of 1,500 to 2,300 mg of sodium per day.
- Long history of smoking and/or drug abuse
- Extreme emotional stress
Other conditions that contribute to developing high blood pressure
Whats Considered High Blood Pressure In Adults
Healthy blood pressure in adults is a reading of 120/80 mm Hg or below. But, what does it mean if your blood pressure numbers are higher than this?
A blood pressure of 120 to 129 mm Hg systolic and under 80 mm Hg diastolic is considered elevated. Elevated blood pressure means you have a greater risk of developing high blood pressure later on.
Your doctor may suggest eating less salt, eating a heart healthy diet, or living a more active lifestyle.
If your blood pressure reading falls into any of the following ranges, its important to talk with your doctor about medication or other lifestyle changes that may help keep your hypertension under control.

Can High Blood Pressure Be Prevented Or Avoided
If your high blood pressure is caused by lifestyle factors, you can take steps to reduce your risk:
- Lose weight.
- Reduce your alcohol consumption.
- Learn relaxation methods.
If your high blood pressure is caused by disease or the medicine you take, talk to your doctor. He or she may be able to prescribe a different medicine. Additionally, treating any underlying disease can help reduce your high blood pressure.
Learning To Cope With Stress Can Help
Stress and hypertension have often been linked, but researchers are still looking into a direct relationship between the two. Still, the best advice to hypertensive patients: Try to relax.
When you are stressed, your body sends stress hormones adrenaline and cortisol into the bloodstream. These hormones create a temporary spike in blood pressure, causing your heart to beat faster and blood vessels to narrow. When the stressful situation is over, blood pressure goes back to its normal level.
Chronic stress, however, may cause your body to stay in this highly-charged state longer than natural.
While stress itself may or may not affect blood pressure, how you cope with stress does. For instance, overeating, smoking and drinking alcohol in response to stressful situations are direct causes of sustained high blood pressure. On the flip side, healthier coping mechanisms like exercising, practicing yoga and meditating can all help lower blood pressure.

About High Blood Pressure
High blood pressure, also known as hypertension, is usually defined as having a sustained blood pressure of 140/90mmHg or above.
The line between normal and raised blood pressure is not fixed and depends on your individual circumstances. However, most doctors agree that the ideal blood pressure for a physically healthy person is around 120/80mmHg.
A normal blood pressure reading is classed as less than 130/80mmHg.
What Are The Benefits And Risks Of Blood Pressure Medicines
The benefits of blood pressure medicines are clear: Blood pressure medicines can help you keep your blood pressure at healthy levels and therefore greatly reduce your risk of heart disease, heart attack, and stroke.
In general, the risks of taking blood pressure medicines are low. However, all medicines have risks. Talk with your doctor or health care professional about the risks of high blood pressure medicines.
Do not stop taking your current medicine without talking to your doctor or health care professional first.

How Do I Know If I Have High Blood Pressure
Theres only one way to know if you have high blood pressure: Have a doctor or other health professional measure it. Measuring your blood pressure is quick and painless.
Talk with your health care team about regularly measuring your blood pressure at home, also called self-measured blood pressure monitoring.
High blood pressure is called the silent killer because it usually has no warning signs or symptoms, and many people do not know they have it.
Choosing A Home Blood Pressure Monitor
The American Heart Association recommends an automatic, cuff-style, bicep monitor.
- Wrist and finger monitors are not recommended because they yield less reliable readings.
- Choose a monitor that has been validated. If you are unsure, ask your doctor or pharmacist for advice or find options at validatebp.org.
- When selecting a blood pressure monitor for a senior, pregnant woman or child, make sure it is validated for these conditions.
- Make sure the cuff fits measure around your upper arm and choose a monitor that comes with the correct size cuff.

High Blood Pressure: Should You Worry
You should be concerned if your blood pressure is going up, but remember that it’s possible to lower it with proper treatment and lifestyle changes.
Its a common condition, and it doesnt have any symptoms: About one out of three U.S. adults has high blood pressure, or hypertension. And nearly one out of three American adults has prehypertension blood pressure numbers that are higher than normal, but not yet in the high blood pressure range which raises the risk of developing high blood pressure.
High blood pressure is a leading cause of heart attack, stroke, heart failure, and kidney disease, so it’s a serious condition that we all must be more conscious of as we age. African-Americans in particular should pay careful attention to blood pressure: In one year, the overall death rate from high blood pressure was 40 percent for African-American females and 52 percent for African-American males more than for any other group.
When Does Blood Pressure Become High Blood Pressure?
According to guidelines followed by doctors, blood pressure is normal if it’s 120/80 or below. The range of 120/80 to 139/89, which was once classified as normal to high, is now considered to be prehypertensive.
How Can You Lower Your High Blood Pressure?
High blood pressure is a treatable condition. Most doctors recommend starting with these lifestyle changes to lower blood pressure:
- Reduce your stress levels

What Constitutes High Blood Pressure
High blood pressure, also called hypertension, happens when the heart pumps blood against the artery walls at higher pressures than normal. It doesnt cause any symptoms, so the only way to know whether its high is to check it. But it isnt diagnosed from just one reading. You need at least two or more readings on two or more separate days before you can know whether you have high blood pressure. This is because your blood pressure changes from day to day and throughout each day, depending on what youre doing. It can increase temporarily from:
Stress or anxiety

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.

Most People With Hypertension Feel Okay
Hypertension usually does not produce any symptoms, because the organs of the body can resist high blood pressure for a long time. Thats why its important to have regular medical examinations to make sure your blood pressure isnt creeping up as you grow older.High blood pressure over a period of time can contribute to many illnesses, including:
- heart attack
The effects of high blood pressure on the arteries are worsened by:
- cigarette smoking
- high levels of saturated fat in the diet
- high blood cholesterol
Responses to some types of stress may affect both blood pressure and changes in the arteries, but this remains scientifically uncertain.
Whats Considered Elevated Blood Pressure
Blood pressure numbers that are higher than 120/80 mm Hg are a warning sign. It means you need to pay attention to your blood pressure and focus on heart-healthy habits.
Although these numbers arent technically considered high blood pressure, youve moved out of the normal range. Elevated blood pressure may turn into high blood pressure, which puts you at an increased risk of heart disease and stroke.
Elevated blood pressure
When your systolic pressure is between 120 and 129mm Hgand your diastolic pressure is less than 80mm Hg, it means you have elevated blood pressure.
No medications are necessary for elevated blood pressure. But your doctor may talk with you about the importance of a healthy lifestyle, such as getting regular exercise, eating a balanced diet, and managing your weight.
You may receive a diagnosis of stage 1 hypertension if:
- your systolic blood pressure is between 130 and 139 mm Hg, or
- your diastolic blood pressure is between 80 and 89 mm Hg
However, the AHA notes that if you get only one reading this high, you may not truly have stage 1 hypertension. What determines the diagnosis of hypertension at any stage is the average of your blood pressure numbers over a period of time.
Your doctor can help you measure and track your blood pressure to confirm whether its too high.
Stage 1 hypertension
If your systolic blood pressure is 130 to 139 mm Hgor your diastolic blood pressure is 80 to 89 mm Hg, its considered stage 1 hypertension.
Can High Blood Pressure Affect Pregnancy
High blood pressure complicates about 10% of all pregnancies. There are several different types of high blood pressure during pregnancy and they range from mild to serious. The forms of high blood pressure during pregnancy include:
Chronic hypertension: High blood pressure which is present before pregnancy.
Gestational hypertension: High blood pressure in the latter part of pregnancy.
Preeclampsia: This is a dangerous condition that typically develops in the latter half of pregnancy and results in hypertension, protein in the urine and generalized swelling in the pregnant person. It can affect other organs in the body and cause seizures .
Chronic hypertension with superimposed preeclampsia: Pregnant people who have chronic hypertension are at increased risk for developing preeclampsia.
Your provider will check your blood pressure regularly during prenatal appointments, but if you have concerns about your blood pressure, be sure to talk with your provider.
How Do Blood Pressure Medicines Work
Blood pressure medicines can work several different ways. Blood pressure medicines can keep blood pressure at a healthy level by1:
- Causing your body to get rid of water, which decreases the amount of water and salt in your body to a healthy level
- Relaxing your blood vessels
- Making your heart beat with less force
- Blocking nerve activity that can restrict your blood vessels
Talk with your health care team about the best type of treatment for you. You may need to take more than one type of medicine to control your blood pressure. You can also talk to your health care team about how long it should take your blood pressure medicine to work.
It is important to take your blood pressure medicine exactly as your doctor tells you to. Do not stop taking your current medicine without talking to your doctor or pharmacist first. Stopping your blood pressure medicine without first talking to your health care team could lead to serious health consequences.
