How Is High Blood Pressure Diagnosed

High Systolic Low Diastolic Blood Pressure – What happens? Solution!

To figure out your blood pressure rate, your health care provider takes blood pressure readings at different times. You need more than 1 reading because blood pressure changes depending on what you are doing and varies during the day. For example, your blood pressure can increase when you are nervous or in a hurry.

If your blood pressure is high while with your health care provider but normal otherwise, you may just be nervous. This effect is common. Even people already being treated for high blood pressure go through this.

What matters is what happens to your blood pressure outside your health care providers office. If you have high blood pressure, you should use a home blood pressure monitor. Ask your health care provider how to use the monitor correctly.

Medications That Can Cause Low Blood Pressure

Several medicines may cause low blood pressure, including some medications used to control high blood pressure.

Working with your doctor or other health care provider to change your medication or adjust your dosage can help control low blood pressure. You should never modify a dose or stop taking a medication without first consulting your health care provider.

Alpha and beta blockers, diuretics, erectile dysfunction drugs, Parkinsons disease drugs and some types of antidepressants can cause low blood pressure.

Medications that can cause low blood pressure include:

  • Benicar a prescription blood pressure medication
  • Cialis an erectile dysfunction drug risk is especially high when taken with nitroglycerin heart medication
  • Cymbalta a serotonin and norepinephrine inhibitor antidepressant
  • Hydrochlorothiazide a widely used generic diuretic
  • Inderal, Innopran XL and other versions of propranolol beta blockers
  • Lasix a diuretic
  • Confusion

Systolic Blood Pressure Facts

  • Both blood pressure numbers are important and either number, including systolic, can be used as a diagnosis for high blood pressure.
  • For people aged 50 or older, doctors tend to monitor systolic blood pressure more closely.
  • High systolic blood pressure is a risk factor for cardiovascular disease.
  • Isolated systolic hypertension is the most common form of high blood pressure 1.
  • Its more typical for the elderly to have high systolic blood pressure but younger people can get it too.

Symptoms Of Low Blood Pressure

Most doctors will only consider chronically low blood pressure as dangerous if it causes noticeable signs and symptoms, such as:

  • Dizziness or lightheadedness
  • Fainting
  • Dehydration and unusual thirst
  • Dehydration can sometimes cause blood pressure to drop. However, dehydration does not always cause low blood pressure. Fever, vomiting, severe diarrhea, overuse of diuretics and strenuous exercise can all lead to dehydration, a potentially serious condition in which your body loses more water than you take in. Even mild dehydration can cause weakness, dizziness and fatigue.
  • Lack of concentration
  • Depression

What To Do If Your Blood Pressure Is Too Low

Blood Pressure Readings Explained

Drops in blood pressure occur when less blood reaches the brain than usual and, therefore, oxygenation is also lower. Although some people have hypotension, drops in blood pressure or faintingnormally occur in a timely manner, being more common in summer. It is necessary to know what should be done if a person is in this situation, so on OneHowTo we explain what to do if your pressure is too low.

When a drop in blood pressure occurs, symptoms such as dizziness, vertigo, nausea, blurred vision, weakness, fainting… are presented. At the appearance of the first signs it will be necessary that the person suffering from hypotension lies down on the floor with legs raised. Thus, they will help blood to flow more easily get to the brain.

Keep the person with their legs about 45 degrees to the ground for a few minutes to facilitate oxygenation, which has been reduced due to the lipothymy or drop in blood pressure.

It will also be convenient to loosen the clothing of the person who has suffered from a drop in blood pressure, to facilitate breathing. You may need to fan them and it will be essential to avoid crowds around them.

If conscious, give them a sugary or caffeinated drink -such as coke or some sweets to revitalize them and increase their blood glucose level.

What Causes High Blood Pressure

The cause of high blood pressure, or hypertension, is often unknown. It develops over time and often happens as a result of unhealthy lifestyle choices, according to the Centers for Disease Control and Prevention .

Occasionally, some people have hypertension caused by an underlying condition, such as kidney disease, adrenal gland tumors or thyroid disorders, says Dr. Wong. Other conditions like pregnancy, diabetes and obesity can also increase your risk.

Some people are susceptible to high blood pressure from certain medications, such as birth control pills, some decongestants and even some over-the-counter pain relievers, says Wong. Illicit drugs, such as cocaine and amphetamines may also raise blood pressure.

High blood pressure is extremely common. A 2017 to 2018 survey conducted by the National Center for Health Statistics found 45.5% of U.S. adults have hypertensionOstchega Y, et al. Hypertension prevalence among adults aged 18 and over: United States, 2017-2018. National Center for Health Statistics. Accessed 7/16/2021. .

Postural Or Orthostatic Hypotension

Postural or orthostatic hypotension occurs when your blood pressure falls after a sudden movement. For example, you may feel dizzy or faint after changing posture, such as sitting up from a lying position, or standing up from a sitting position. This may cause you to lose your balance and fall over. You may also feel light-headed, have blurred vision, or lose consciousness.

The symptoms of postural or orthostatic hypotension should only last a few minutes as your blood pressure adjusts to your new position. This type of low blood pressure tends to affect people more as they get older when it can lead to more frequent falls. Similar symptoms may also occur after exercise.

Blood Pressure: How Low Can You Go

What’s considered low blood pressure for you may be normal for someone else. Most doctors consider blood pressure too low only if it causes symptoms.

Some experts define low blood pressure as readings lower than 90 mm Hg systolic or 60 mm Hg diastolic. If either number is below that, your pressure is lower than normal.

A sudden fall in blood pressure can be dangerous. A change of just 20 mm Hg a drop from 110 systolic to 90 mm Hg systolic, for example can cause dizziness and fainting when the brain fails to receive enough blood. And big drops, such as those caused by uncontrolled bleeding, severe infections or allergic reactions, can be life-threatening.

Your Blood Pressure Numbers And What They Mean

Lower Your Blood Pressure – Information About Blood Pressure Numbers

Your blood pressure is recorded as two numbers:

  • Systolic blood pressure indicates how much pressure your blood is exerting against your artery walls when the heart beats.
  • Diastolic blood pressure indicates how much pressure your blood is exerting against your artery walls while the heart is resting between beats.

What Is High Blood Pressure

Blood pressure is defined as the force of blood pushing against the walls of the arteries as the heart pumps blood. High blood pressure also known as hypertension is a disease in which blood flows through blood vessels at a higher than normal pressure.

Blood pressure is measured with two numbers. The first, or top number, is the pressure in your blood vessels when your heart beats, called the systolic pressure. Systolic pressure is the higher of the two numbers. The second, or bottom number, measures the force of blood in your arteries while your heart is relaxed between beats. The bottom number is the lower of the two and is called the diastolic pressure.

Normal pressure is 120/80 or lower. Your blood pressure is considered high if it reads 130/80. Stage 2 high blood pressure is 140/90 or higher. If you get a blood pressure reading of 180/110 or higher more than once, seek medical treatment right away. A reading this high is considered hypertensive crisis.

Readings between 120/80 and 129/89 are considered pre-hypertension. People with pre-hypertension do not have blood pressure as low as it should be but are not yet considered to have high blood pressure.

Dangers Of Low Blood Pressure

Low blood pressure may not be discussed as often as high blood pressure, but it should be addressed, as prolonged low blood pressure can negatively affect your organs.

A certain amount of blood pressure is needed to maintain blood flow to the organs, says Dr. Wong. The blood supplies oxygen and nutrients to these organs. If the blood pressure is too low, an adequate blood supply cannot get to these organs.

If left untreated, low blood pressure can increase your risk of fainting, heart attack and organ damage, adds Dr. Desai.

British Columbia Specific Information

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.

Some people, especially if you have diabetes, are at a higher risk of your blood pressure temporarily dropping after eating or when getting up from a chair or from lying down in bed, for example. The former is whats called postprandial hypotension and the latter is orthostatic hypotension. Normally, when you’re digesting food, or when you change your body position from sitting to standing, your cardiovascular system adapts by beating harder as well as more rapidly, and constricting the diameter of certain blood vessels, such as those far from your intestine where digestion occurs. These physiological changes all collaborate to maintain your blood pressure. But, if these changes do not occur fast or adequately enough, your blood pressure can drop, sometimes to dangerous levels.

How Is Low Blood Pressure Diagnosed

Your doctor will ask about your symptoms and take your blood pressure by placing a blood pressure cuff around your upper arm. The cuff will tighten on your arm, and the monitor will measure your systolic and diastolic pressure. A blood pressure reading of 90/60 mm Hg is considered low blood pressure.

Low blood pressure may be a sign of an underlying condition, so your doctor will try to determine what caused your blood pressure to drop. Depending on your medical history and symptoms, your doctor may also check your heart using an echocardiogram, electrocardiogram, or stress test. Your doctor may also perform blood tests to check for:

  • Hormonal imbalances.

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.

Which Blood Pressure Number Is Important

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.

High Blood Pressure Numbers: Normal vs. Dangerous

According to Luke Laffin MD, a preventive cardiologist at the Cleveland Clinic, There are many normal reasons for lower blood pressure, including younger age and small stature. Some people just have a genetic predisposition to low blood pressure.

Generally, if there are no symptoms, low blood pressure is not considered a problem. Though some people do naturally have blood pressure that tends to be on the low side and have no symptoms.

The ‘bottom’ Blood Pressure Number Matters Too

HealthDay Reporter

THURSDAY, July 18, 2019 — When it comes to blood pressure readings, the “top” number seems to grab all the attention.

But a large, new study confirms that both numbers are, in fact, critical in determining the risk of heart attack and stroke.

Blood pressure measurements are given as a “top” and “bottom” number. The first reflects systolic blood pressure, the amount of pressure in the arteries as the heart contracts. The second reflects diastolic blood pressure, the pressure in the arteries between heart muscle contractions.

For years, systolic blood pressure has been seen as the one that really matters. That’s based on studies — including the famous Framingham Heart Study — showing that high systolic blood pressure is a stronger predictor of heart disease and stroke.

At the same time, though, doctors measure both systolic and diastolic blood pressure, and treatment guidelines are based on both. So just how important is that diastolic number?

“The idea behind this new study was to address the confusion,” said lead researcher Dr. Alexander Flint, an investigator with Kaiser Permanente Northern California’s division of research.

Using medical records from 1.3 million patients, his team confirmed that, yes, high systolic blood pressure was a stronger risk factor for heart attack and stroke. But those risks also climbed in tandem with diastolic pressure and people with normal systolic readings were still at risk if their diastolic pressure was high.

Why Diastolic Pressure Is Important Too

The findings about low diastolic blood pressure are intriguing, and they make sense intuitively, Dr. Conlin says. Diastolic pressure is measured during the point in the heart cycle when blood flows into the coronary arteries that feed the heart. When those arteries are clogged with fatty deposits, blood pressure beyond the narrowed areas will drop as blood works its way through the narrowed channels. As a result, part of the heart muscle may not get enough blood. Starved for oxygen and nutrients, the heart may become weak and prone to damage.

Rates Of High Blood Pressure Vary By Geography

High blood pressure is more common in some areas of the United States than in others. Below is a map showing the self-reported rate of hypertension by state in 2011 . However, this map likely underreports the true effect of hypertension in each state, because about 1 in 5 adults with high blood pressure is unaware of it and would not report having it.5

Elevated Systolic Blood Pressure

An elevated blood pressure reading is when systolic blood pressure is between 120-129 mmHg and diastolic is less than 80 mmHg.

If systolic blood pressure is elevated, the risk of developing high blood pressure is greater. For consistent readings in this range a doctor will typically recommend the following:

  • Recommend lifestyle changes.
  • Attend scheduled physician visits.

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.
