When doctors take a person’s blood pressure, they measure the force that blood exerts on the walls of the arteries as it flows through them.

If blood pressure is too high for too long, it can cause serious damage to the blood vessels.

This damage can result in a range of complications, some of which can be life threatening. They include heart failure, vision loss, stroke, kidney disease, and other health problems.

There are ways of managing high blood pressure, or hypertension. High blood pressure often does not cause symptoms, but regular screening can help a person know if they need to take preventive action.

In the United States, around 75 million people, or 29% of the population, have high blood pressure, according to the Centers for Disease Control and Prevention (CDC).

In this article, we look at the causes of high blood pressure and how to treat it. We also explain the blood pressure measurements that health authorities consider to be healthy and too high.

 What is high blood pressure? 

 

                   Leaving high blood pressure untreated may damage the blood vessels.

The heart could be a muscle that pumps blood round the body. because it travels, the blood delivers gas to the body’s very important organs.

Sometimes, a tangle within the body makes it tougher for the guts to pump the blood. this might happen, for instance, if associate degree artery becomes too slender.

Persistent high vital sign will place a strain on the walls of the arteries. this may cause a range of health issues, a number of which might be life threatening.

High blood pressure chart

The chart below shows measures for normal and high blood pressure, according to the American Heart Association (AHA).

Doctors measure blood pressure in millimeters of mercury (mm Hg).

Systolic pressure measures the pressure in the arteries as the heart contracts and is the top number on a blood pressure reading. Diastolic, which is the lower number, represents the blood pressure when the heart is resting between beats.

Sometimes, there's no apparent cause. during this case, a doctor can diagnose primary high blood pressure.

Consuming a high fat diet, carrying excess weight, drinking heaps of alcohol, smoking tobacco, {and the and therefore the and additionally the} use of some medications also increase the chance.

How to lower blood pressure

Treatment can rely upon many factors, including:

  • how high the blood pressure is

  • the risk of upset or a stroke

The doctor can advocate totally different treatments as force per unit area will increase. For slightly high force per unit area, they'll counsel creating modus vivendi changes and watching the force per unit area.

If force per unit area is high, they'll advocate medication. the choices could amendment over time, in keeping with however severe the cardiovascular disease is and whether or not complications arise, like renal disorder. Some individuals might have a mix of many totally different medications.

Medications

Conventional medicine for treating high force per unit area include:

1) Angiotensin converting enzyme inhibitors

Angiotensin changing protein (ACE) inhibitors block the actions of some hormones that regulate force per unit area, like angiotensin. angiotensin causes the arteries to constrict and will increase blood volume, leading to inflated force per unit area.

ACE inhibitors will cut back the blood offer to the kidneys, creating them less effective. As a result, it's necessary for individuals taking ACE inhibitors to own regular blood tests.

People shouldn't use ACE inhibitors if they:

    •   are pregnant

    •   have a condition that affects the blood offer to the kidneys

    ACE inhibitors could cause the subsequent aspect effects, that typically resolve when some      days:

    •  fatigue

    •   weakness

    •  headaches

    •  a persistent dry cough

If the aspect effects square measure persistent or too unpleasant to manage, a doctor could inflict Associate in Nursing angiotensin receptor antagonist instead.

These various medications usually cause fewer aspect effects, however they'll embody vertigo, headaches, and inflated atomic number 19 levels within the blood.

2) Calcium channel blockers (CCBs)

Calcium channel blockers (CCBs) aim to decrease metal levels within the blood vessels. this may relax the tube-shaped structure sleek muscle, inflicting the muscle to contract less forcefully, the arteries to widen, and force per unit area to travel down.

CCBs might not invariably be appropriate for individuals with a history of heart condition, disease, or circulation problems. A doctor will advise on taking CCBs and which kind of CCB is safe to use.

3) diuretic drug diuretics

Thiazide diuretics facilitate the kidneys get obviate atomic number 11 and water. This lowers blood volume and pressure.

The following aspect effects will occur, and a few of them could persist:

  • low blood atomic number 19, which may have an effect on heart and excretory organ perform
  • impaired aldohexose tolerance
  • erectile pathology

People taking diuretic drug diuretics ought to have regular blood and water tests to watch their glucose and atomic number 19 levels.

4) Beta-blockers

Beta-blockers were once fashionable for treating cardiovascular disease, however doctors solely tend to inflict them currently once different treatments haven't been prosperous.

Beta-blockers slow the center rate and cut back the force of the heartbeat, inflicting a call force per unit area.

Side effects could include:

  • fatigue

  • erectile pathology

Beta-blockers square measure usually the quality medication for someone with terribly high force per unit area, referred to as a hypertensive crisis.

5) peptidase inhibitors

Aliskiren (Tekturna, Rasilez) reduces the assembly of peptidase, Associate in Nursing protein that the kidneys turn out.

Renin helps turn out a secretion that narrows blood vessels and raises force per unit area. Reducing this secretion causes the blood vessels to widen and force per unit area to fall.

This drug is comparatively new, and health care professionals square measure still determinative its best use and dose.

Possible aspect effects include:

  • diarrhea
  • dizziness
  • flu-like symptoms
  • fatigue
  • a cough

It is essential to browse the packaging of any medication to examine for interactions with different medicine.

Diastolic and blood pressure

There area unit 2 elements to a pressure measurement:

Systolic pressure: this can be the pressure once the center contracts.

Diastolic pressure: this can be the pressure between heartbeats.

If pressure is 120/80 mm Hg, it implies that the blood pressure is one 120 mm Hg and also the blood pressure is 80 mm Hg.

Learn additional here regarding what makes beat and blood pressure.

 

Diagnosis

There area unit totally different devices for activity pressure. A doctor can usually use a manual pressure gage with a medical instrument. This contains a pressure cuff that they place round the person’s arm.

Digital devices area unit appropriate for home use, and that they on the market from pharmacies and for purchase on-line.

Read our review of the most effective home pressure monitors presently on the market for home use.

When an individual gets a pressure reading, they'll have one in all the following:

Normal: but 120/80 mm Hg.

Elevated: 120–129/80 mm Hg. At this stage, a doctor can advise the individual to form way changes to come back their pressure to the traditional vary.

Stage 1 hypertension: 130–139/80–89 mm Hg.

Stage 2 hypertension: Over 140/90 mm Hg

Hypertensive crisis: 180/120 mm Hg or on top of

A person with a hypertensive crisis desires immediate medical attention.

A person can generally would like over one reading to substantiate a diagnosing, as numerous factors will have an effect on the result.

Blood pressure will fluctuate:

  • according to the time of day
  • when an individual feels anxiety or stress
  • after intake

However, a doctor can take immediate action if a reading shows terribly high blood pressure vital sign ,pressure level force per unit area unit or if there are signs of organ injury or different complications.

Additional tests

Other tests will facilitate make sure a diagnosing.

Urine and blood tests: These will check for underlying issues, like a body waste infection or urinary organ injury.

Exercise stress test: A aid skilled can live a person’s pressure before, during, and once employing a stationary bicycle or a treadmill. The results will provide vital clues regarding heart health.

Electrocardiogram (ECG): AN electrocardiogram tests electrical activity within the heart. For an individual with cardiovascular disease and high steroid alcohol levels, a doctor could order AN electrocardiogram as a baseline for comparison future results.

Changes in future results may show that artery unwellness is developing or that the center wall is thickening.

Holter monitoring: for twenty-four hours, the individual carries AN electrocardiogram transportable device that connects to their chest through electrodes. This device will give an outline of pressure throughout the day and show however it changes because the level of activity varies.

chocardiogram: Ultrasound waves show the heart in motion. The doctor will be able to detect problems, such as thickening of the heart wall, defective heart valves, blood clots, and excessive fluid around the heart.

Dangers and side effects of hypertension

A healthy blood pressure is essential for maintaining bodily functions.

High blood pressure can have a severe impact on:

The cardiovascular system: High blood pressure can cause the arteries to harden, increasing the risk of a blockage.

The heart: A blockage can reduce blood flow to the heart, increasing the risk of angina, heart failure, or a heart attack.

The brain: A blockage in the arteries can lower or prevent blood flow to the brain, leading to a stroke.

The kidneys: High blood pressure can result in kidney damage and chronic kidney disease.

All of these effects can be life threatening.

Can you take decongestants?

Decongestants are a useful over-the-counter remedy when people have a stuffy or runny nose, but some decongestants can raise blood pressure.

Ingredients that can have this effect include:

  • oxymetazoline
  • phenylephrine
  • pseudoephedrine

A person should explain to their pharmacist that they have high blood pressure and ask them to recommend a suitable option.

Is high blood pressure genetic?

The main risk factors for high blood pressure are likely to be environmental, but genetic factors may play a role. Hypertension can run in families, and people from certain ethnic and racial backgrounds appear to have a higher risk.

According to the CDC, however, people in a family often share similar lifestyles, such as dietary choices.

If a person has genetic factors that increase their susceptibility to high blood pressure, and they also make lifestyle choices that increase this risk, they will likely have a greater chance of developing hypertension.

How much sodium per day?

The AHA recommend that people limit their salt intake to no more than 2,300 milligrams (mg) a day and preferably reducing it to 1,500 mg. On average, people in the U.S. currently consume more than 3,400 mg of sodium daily.

For most people, the natural sodium content in vegetables, for example, is enough for their body’s needs. Avoiding the salt shaker and eating less processed and premade food are good ways to cut salt intake.

Complications

Without treatment or taking measures to manage force per unit area, excessive pressure on the artery walls will cause injury of the blood vessels, that could be a variety of disorder. It may also injury some important organs.

Possible complications of high force per unit area include:

  • stroke
  • heart attack and failure
  • blood clots
  • aneurysm
  • kidney malady
  • thickened, narrow, or torn blood vessels within the eyes
  • metabolic syndrome
  • brain perform and memory issues

Seeking early treatment and managing force per unit area will facilitate stop several health complications.

Risk factors

The risk factors for top force per unit area embody the following:

Age: the danger will increase with age as a result of the blood vessels lessen versatile.

Family history and genetic factors: those that have shut members of the family with high blood pressure square measure additional possible to develop it.

Ethnic background: African Americans have the next risk of developing high blood pressure than different teams within the us.

Obesity and being overweight: individuals with overweight or fleshiness square measure additional possible to develop high force per unit area.

Physical inactivity: A inactive life style will increase the danger.

Smoking: once individuals smoke, the blood vessels slender, and force per unit area rises. Smoking additionally reduces the blood’s chemical element content, that the heart pumps quicker to compensate. This, too, will increase force per unit area.

Diabetes: High force per unit area usually happens aboard kind one polygenic disorder. Following a treatment conceive to manage polygenic disorder will scale back the danger.

Pregnancy: High force per unit area is additional possible throughout physiological state thanks to secretion changes. high blood pressure is additionally a signal of pre-eclampsia, a doubtless severe placental disorder.

Sleep apnea: individuals with sleep disorder momentarily stop respiratory whereas they sleep. specialists say there square measure links with high blood pressure.

 

When to examine a doctor

Many people with high force per unit area don't have symptoms. For this reason, they need to have regular screening, particularly those with the next risk.

This cluster includes:

  • people with fleshiness or overweight
  • African Americans
  • those with a previous history of high force per unit area
  • those with force per unit area that's at the high finish of traditional (from 130–139/ 85–89 millimeter Hg)
  • people with bound health conditions
  • The U.S. Preventive Services Task Force (USPSTF) advocate annual screening for:
  • adults aged 40 years or older
  • those with Associate in Nursing elevated risk of high force per unit area
  • Persons with the next risk embody those who:
  • have high to traditional force per unit area (130 to 139/85 to 89 millimeter Hg)
  • have overweight or fleshiness
  • are African Americans

Adults aged 18–39 years United Nations agencyse force per unit area is traditional (less than 130/85 millimeter Hg) and who don't produce other risk factors ought to have additional screening each 3–5 years.

If rescreening within the doctor’s workplace shows that force per unit area has up, the USPSTF advocate that the person use Associate in Nursing mobile force per unit area monitor for twenty-four hours to assess their force per unit area additional. If this continues to indicate high force per unit area, the doctor can diagnose high blood pressure.

The USPSTF don't presently advocate routine screening for those aged seventeen years and below.
