What is the symptoms of high blood pressure

One in three adults in the U.S. has high blood pressure and many don’t even know it. How can this be? Because high blood pressure rarely has any symptoms. 

“High blood pressure or hypertension is known as a silent disease because you may not feel any symptoms at all,” says Priscilla Bullen, FNP-BC, of Riverside Primary Care Hidenwood. “It increases your risk of heart disease, heart failure, stroke and heart attack.”

Blood pressure is the force of blood pushing against your blood vessel walls. High blood pressure is when that force is higher than normal. It often has no signs or symptoms and can lead to other health problems if it’s not treated.

Blood pressure is mostly a silent disease

Unfortunately, high blood pressure can happen without feeling any abnormal symptoms.

Moderate or severe headaches, anxiety, shortness of breath, nosebleeds, palpitations, or feeling of pulsations in the neck are some signs of high blood pressure. Often, these are late signs that high blood pressure has existed for some time, therefore annual checks are recommended for all adults.

Get to know your numbers

Because there aren’t any symptoms, it’s important to have your blood pressure checked regularly. Get to know the numbers and when to get help from your doctor.

Your blood pressure will have two numbers:

  • Systolic is the upper number, measuring when your heart is forcing blood through your vessels.
  • Diastolic is the lower number, measuring pressure between heart beats.

For example, 120/80 indicates a systolic blood pressure of 120 and a diastolic blood pressure of 80 mm/Hg.

What is a normal blood pressure?

Both the American Heart Association and the U.S. Preventive Services Task Force have published guidelines for defining healthy and elevated blood pressure. You can follow either guidelines, depending on what you and your doctor agree is acceptable.

USPSTF Guidelines for Blood Pressure

Normal Systolic: Less than 120 mm Hg
Diastolic:Less than 80 mm Hg
Elevated Systolic: 120-129 mm Hg
Diastolic: <Less than 80 mm Hg

AHA Guidelines for Blood Pressure

Normal Systolic: Less than 120 mm Hg
Diastolic: Less than 80 mm Hg
Elevated Systolic: 120-129 mm Hg
Diastolic: Less than 80 mm Hg
High Blood Pressure Stage 1 (Hypertension) Systolic: 130-139 mm Hg
Diastolic: 80-89 mm Hg
High Blood Pressure Stage 2 (Hypertension) Systolic: 140 mm Hg or higher
Diastolic: 90 mm Hg or higher
Hypertensive Crisis Systolic: Higher than 180 mm Hg
Diastolic: Higher than 120 mm Hg

Who is at risk for high blood pressure?

Your family history, lifestyle and medications can increase the chances you’ll develop high blood pressure. Risk factors for high blood pressure include:

  • Age
  • Overweight
  • Family history
  • Diet high in salt
  • Drinking too much
  • Some medications, nonsteroidal anti-inflammatories, also known as NSAIDS, some decongestants, weight loss medicines and stimulants)
  • Some underlying health conditions, such as obstructive sleep apnea, kidney conditions, adrenal gland tumors and thyroid diseases
  • Inactivity
  • Tobacco and illicit drug use
  • Other

Unfortunately, family history is a large contributing factor. Even if you eat well, are physically active and avoid risk factors, you may still experience high blood pressure.

When to see a doctor

Consult your doctor if you fall in the at-risk or high blood pressure categories above.

If your blood pressure is in the crisis range, contact your doctor immediately. Call 911 if you’re experiencing any other symptoms like chest pain, blurred vision or slurred speech.

How is high blood pressure treated?

Treatment for high blood pressure will commonly include medication and healthy lifestyle changes such as:

  • Losing weight
  • Eating a healthful diet
  • Quitting smoking
  • Drinking less alcohol
  • Reducing stress 

“Changing a few daily habits like walking more and eating less salt can bring blood pressure into normal range,” says Bullen.

High blood pressure, or hypertension, rarely has noticeable symptoms. But if untreated, it increases your risk of serious problems such as heart attacks and strokes.

Around a third of adults in the UK have high blood pressure, although many will not realise it.

The only way to find out if your blood pressure is high is to have your blood pressure checked.

What is high blood pressure?

Blood pressure is recorded with 2 numbers. The systolic pressure (higher number) is the force at which your heart pumps blood around your body.

The diastolic pressure (lower number) is the resistance to the blood flow in the blood vessels.

They're both measured in millimetres of mercury (mmHg).

As a general guide:

  • high blood pressure is considered to be from 140/90mmHg (or an average of 135/85mmHg at home) – or 150/90mmHg (or an average of 145/85mmHg at home) if you're over the age of 80
  • ideal blood pressure is usually considered to be between 90/60mmHg and 120/80mmHg, while the target for over-80s is below 150/90mmHg (or 145/85mmHg at home)

Blood pressure readings between 120/80mmHg and 140/90mmHg could mean you're at risk of developing high blood pressure if you do not take steps to keep your blood pressure under control.

Everyone's blood pressure will be slightly different. What's considered low or high for you may be normal for someone else.

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:

  • heart disease
  • heart attacks
  • strokes
  • heart failure
  • peripheral arterial disease
  • aortic aneurysms
  • kidney disease
  • vascular dementia

If you have high blood pressure, reducing it even a small amount can help lower your risk of these health conditions.

Check your blood pressure

The only way of knowing whether you have high blood pressure is to have a blood pressure test.

All adults over 40 are advised to have their blood pressure checked at least every 5 years. 

Getting this done is easy and could save your life.

You can get your blood pressure tested at a number of places, including:

  • at your GP surgery
  • at some pharmacies
  • as part of your NHS Health Check
  • in some workplaces

You can also check your blood pressure yourself with a home blood pressure monitor.

Things that can increase your risk of getting high blood pressure

It's not always clear what causes high blood pressure, but there are things that can increase your risk.

You might be more at risk if you:

  • are overweight
  • eat too much salt and do not eat enough fruit and vegetables
  • do not do enough exercise
  • drink too much alcohol or coffee (or other caffeine-based drinks)
  • smoke
  • do not get much sleep or have disturbed sleep
  • are over 65
  • 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.

Treatment for high blood pressure

Doctors can help you keep your blood pressure to a safe level using:

  • lifestyle changes
  • medicines

What works best is different for each person.

Talk to your doctor to help you decide about treatment.

This patient decision aid (PDF, 132kb) can also help you to understand your treatment options.

Lifestyle changes to reduce blood pressure

These lifestyle changes can help prevent and lower high blood pressure:

  • reduce the amount of salt you eat and have a generally healthy diet
  • cut back on alcohol 
  • lose weight if you're overweight
  • exercise regularly
  • cut down on caffeine
  • stop smoking

Some people with high blood pressure may also need to take 1 or more medicines to stop their blood pressure getting too high.

Medicines for high blood pressure

If you're diagnosed with high blood pressure, your doctor may recommend taking 1 or more medicines to keep it under control.

These come as tablets and usually need to be taken once a day.

Common blood pressure medicines include:

  • ACE inhibitors – such as enalapril, lisinopril, perindopril and ramipril
  • angiotensin-2 receptor blockers (ARBs) – such as candesartan, irbesartan, losartan, valsartan and olmesartan
  • calcium channel blockers – such as amlodipine, felodipine and nifedipine or diltiazem and verapamil
  • diuretics – such as indapamide and bendroflumethiazide
  • beta blockers – such as atenolol and bisoprolol
  • alpha blockers – such as doxazosin
  • other diuretics – such as amiloride and spironolactone

The medicine recommended for you will depend on things like how high your blood pressure is, your age and your ethnicity.
