How High Is Too High For Blood Pressure

What Does High Blood Pressure Feel Like

Blood Pressure: How High is Too High and How Do I Lower it Safely?

High blood pressure often doesn’t have any symptoms, so you usually don’t feel it.

Hypertension is usually diagnosed by a health care professional during a routine checkup. The average person should get a blood pressure reading at least once a year. As a cardiologist, I think its important for everyone to know their numbers. That means knowing what your blood pressure is. And it also means knowing your blood sugar level, cholesterol and body mass index. When you know your numbers, you can work with your doctor to make a plan to reduce any risks.

Blood pressure is even more important to pay attention to, though, if you have a close relative with hypertension or other risk factors. And know that if your blood pressure is extremely high, you may have unusually severe headaches, chest pain, difficulty breathing or get easily worn out by workouts. If you have any of these symptoms, see your doctor right away.

High Blood Pressure In Adults

Healthy blood pressure in adults is a reading below 120 systolic and 80 diastolic. Blood pressure between 120 to 129 systolic and under 80 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.

What Do Blood Pressure Readings Mean

Blood pressure readings can vary in a single person throughout the day depending on the situation. Factors such as stress, anxiety, foods are eaten , smoking or exercise can cause pressure to rise.

The American Heart Association defines normal blood pressure as less than 120/80. Elevated blood pressure ranges between 120/80 and 129/80, and high blood pressure is 130/80 and higher. In pregnancy, normal blood pressure should be below 120/80.

If your blood pressure reaches the high range, you should see your doctor about lifestyle changes, and possibly medication especially if you have other risk factors, such as diabetes or heart disease.

High blood pressure may indicate an emergency situation. If this high blood pressure is associated with chest pain, shortness of breath, headache, dizziness, or back or abdominal pain, seek medical care immediately. If you are experiencing no associated symptoms with a high blood pressure reading such as this, re-check it again within a few minutes and contact your doctor or go to an emergency room if it is still high.

If your blood pressure is lower than about 100/60 you may have low blood pressure, depending on the associated symptoms. If you are unsure, check with your doctor.

Why Is It Important To Know If You Have High Blood Pressure

Early detection of high blood pressure is very important. Often referred to as the silent killer because it may show no symptoms, high blood pressure puts you at an increased risk for heart disease, heart failure, and stroke, among other things. According to the Centers for Disease Control and Prevention, in 2013, more than 360,000 deaths in the United States included high blood pressure as a primary or contributing cause.

The Ideal Blood Pressure Levels

Diastolic Pressure Definition

Maximum blood pressure values of 120/80 when physically at rest are considered ideal for an adult. Blood pressure levels up to 139/89 are within the normal range that do not pose any health risk. Levels over 129/84, however, are already considered in the elevated-normal range.

Blood pressure readings over 159/99 are considered to be minor hypertension and require a medical attention to avoid harmful complications.

How To Measure Blood Pressure

Usually a nurse checks your blood pressure to make sure its not too low or too high before your doctors appointment. But you can also check your readings manually at home. You can use an inflatable cuff similar to those used at your doctors office. Or you can use a digital blood pressure monitor with automatic cuff inflation.

Read the directions carefully when measuring your blood pressure. Certain factors can cause a temporary rise in blood pressure. These factors include:

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.

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.

High blood pressure, also called hypertension, can damage your blood vessels, heart and kidneys. This damage can cause a heart attack, stroke or other health problems. Your blood pressure reading is based on two measurements called systolic and diastolic. The systolic and diastolic are written as a ratio, for example . A reading of more than 140/90 mmHg taken at your healthcare providers office may indicate high blood pressure. This figure is different for people with diabetes whose blood pressure should be below 130/80 mmHg. People suffering from other illnesses will have different target normal values.

Healthy lifestyle choices can help lower your blood pressure and improve your health. For information on healthy eating for lowering your blood pressure, see:

Why Is Your Blood Pressure Important

Your blood pressure is important because if it is too high, it affects the blood flow to your organs. Over the years, this increases your chances of developing heart disease, stroke, chronic kidney disease, eye disease, erectile dysfunction and other conditions.

Very occasionally, people with very high blood pressure are at serious risk of problems and need urgent treatment in hospital to reduce the risk of a stroke or heart attack.

Current Australian guidelines recommend that if you have persistent raised blood pressure over 160/100 mmHg, but are at low risk of having a stroke or heart attack, you should talk to your doctor or specialist about taking medication to lower your blood pressure.

For further information, visit the Choosing Wisely Australia website.

If youre over 18, you should have your blood pressure checked by your doctor at least every 2 years, or more often if advised.

Blood Pressure: How High Is Too High And What Can You Do

Alan Segal, MD, is a nephrologist at The University of Vermont Medical Center where he is also Director of the Nephrology Fellowship Program. He is also an associate professor at the Larner College of Medicine at UVM.

High blood pressure, clinically known as hypertension, affects nearly 75 million adults in the United States and 1 billion people globally. Although one-third of adults in the United States are affected, only half of them have their blood pressure controlled.

That has significant costs, both in terms of health and economics. The estimated economic burden for hypertension in 2014 was nearly $75 billion worldwide. It is the single largest contributor to death and disability worldwide, in large part because it dramatically increases the risk of stroke, heart attack, heart failure, and chronic kidney disease. For example, starting at a blood pressure of 115/75, the risk of death doubles for every 20 mmHg increase in systolic pressure , and for every 10 mmHg increase in diastolic pressure .

Hypertension is the most common reason for office visits in adults and more prescriptions are written for blood pressure lowering drugs than for any other drug class.

Lets review the most frequently asked questions about hypertension and how to treat it.

What is blood pressure and what is hypertension?

According to the Joint National Committee :

When To See A Doctor For High Blood Pressure

Is your blood pressure too high ? How to manage

Since the majority of individuals living with hypertension dont experience symptoms, its likely youll find out about your high blood pressure numbers during a doctors appointment. After being diagnosed with hypertension, you should continue to see your doctor, especially if you cant control your blood pressure with prescribed medication or recommended lifestyle changes.

Youre experiencing a hypertensive crisis

You should also see or contact your doctor if you experience a related high blood pressure event called a hypertensive crisis. There are two main types of hypertensive crises:

Hypertensive emergency

A hypertensive emergency is a rare medical emergency where your blood pressure is 180/120 mm Hg or higher and you are experiencing symptoms of target organ damage. If this happens to you, call emergency medical services right away.

Symptoms of target organ damage include:

  • Difficulty speaking

Hypertensive urgency

If youre experiencing elevated blood pressure of 180/120 mm Hg or higher but are not experiencing any of the above symptoms, this is called hypertensive urgency. Wait five minutes and take your blood pressure a second time. If it is just as high, call your doctors office. Your doctor might want to adjust your medications. Hypertensive urgency does not usually result in hospitalization.

What Are The Symptoms Of High 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.

Can Exercise Help Lower High Blood Pressure

Exercise and physical activity help lower blood pressure by helping you lose weight and keeping your heart and blood vessels in good condition.

Weight loss achieved through diet and exercise helps control factors such as blood sugar, and other complications of obesity. Avoiding these complications helps lower blood pressure and prevent high blood pressure.

Consult your doctor before starting any new exercise program. Cardiovascular activities including walking, jogging, biking, or swimming for 30 to 45 minutes per day can help lower blood pressure.

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.

How To Properly Interpret Blood Pressure Levels

Is Your Blood Pressure is Too High? (How High is Too High?)

Because blood pressure is different for every person, there are no specific limits except for excessively high blood pressure values for when it is advisable to see a doctor. However, if the levels rise excessively or the person has symptoms such as shortness of breath, sensations of pressure in the chest, dizziness, or nausea, they should seek medical attention immediately.

Increase Activity And Exercise More

In a 2013 study, sedentary older adults who participated in aerobic exercise training lowered their blood pressure by an average of 3.9 percent systolic and 4.5 percent diastolic . These results are as good as some blood pressure medications.

As you regularly increase your heart and breathing rates, over time your heart gets stronger and pumps with less effort. This puts less pressure on your arteries and lowers your blood pressure.

How much activity should you strive for? A 2013 report by the American College of Cardiology and the American Heart Association advises moderate- to vigorous-intensity physical activity for 40-minute sessions, three to four times per week .

If finding 40 minutes at a time is a challenge, there may still be benefits when the time is divided into three or four 10- to 15-minute segments throughout the day .

The American College of Sports Medicine makes similar recommendations .

But you dont have to run marathons. Increasing your activity level can be as simple as:

  • using the stairs
  • going for a bike ride
  • playing a team sport

Just do it regularly and work up to at least half an hour per day of moderate activity.

One example of moderate activity that can have big results is tai chi. A 2017 review on the effects of tai chi and high blood pressure shows an overall average of a 15.6 mm Hg drop in systolic blood pressure and a 10.7 mm Hg drop in diastolic blood pressure, compared to people who didnt exercise at all .

Measuring Ambulatory Blood Pressure

High blood pressure can also be diagnosed through a special device called an ambulatory blood pressure monitor. A doctor, nurse or pharmacist will get you to wear the device for a full day. The device measures blood pressure every 20 to 30 minutes and gives the doctor an average of your blood pressures during the day and while you are sleeping. These devices are not available everywhere and can be uncomfortable to wear.

What Is Considered High Blood Pressure For Older Adults

Recent updates to guidelines from the American Heart Association and the American College of Cardiology changed the definition of high blood pressure or hypertension for most people. High blood pressure is now generally defined as 130 or higher for the first number, or 80 or higher for the second number . However, there are important considerations for older adults in deciding whether to start treatment for high blood pressure, including other health conditions and overall fitness. If your blood pressure is above 130/80, your doctor will evaluate your health to determine what treatment is needed to balance risks and benefits in your particular situation.

Why Do I Need A Blood Pressure Chart

Keeping Blood Pressure from Being Too High: How

Older persons, those with a hereditary predisposition, heart problems, or systemic diseases are all especially prone to high blood pressure. A blood pressure chart helps a person to monitor their individual values, to identify abnormalities early on, and to treat unhealthy blood pressure values at an early stage.

  • What medications are you on?
  • Did you forget your blood pressure medication?
  • What symptoms do you have?
  • How long have you had these symptoms?

If youre unable to check your blood pressure, but think it might be high, dont hesitate to call 911 or go to the emergency room.
