Hypertension
Understand your blood pressure—and what you can do about it.
Start with the questions that matter: whether the diagnosis is confirmed, why blood pressure rises, what medical care may involve, and how daily life can help.

High blood pressure makes more sense when you begin with the right questions.
Second pillar
Lifestyle care
Build a realistic plan for food, movement, sleep, stress, connection, and substances. These actions remain part of care whether or not you take medicine.
What it is
Hypertension means blood pressure stays higher than recommended over time.
Blood pressure is the force of blood pushing against the walls of your arteries. The top number shows the pressure when the heart squeezes; the bottom number shows the pressure when it relaxes.
The important part
Most people feel no symptoms. Measuring blood pressure is how it is found.
About 45 in 100
U.S. adults have high blood pressure.
About 24 in 100
Adults with hypertension reach the recommended goal of 130/80.
Do I have it?
One high reading is a signal—not usually the whole diagnosis.
Blood pressure changes throughout the day. The aim is to find your usual pattern with correct technique and repeated readings.
Normal
Below 120
and below 80
Elevated
120–129
and below 80
Stage 1
130–139
or 80–89
Stage 2
140 or higher
or 90 or higher
The top number is the pressure when the heart squeezes. The bottom number is the pressure when it relaxes. A diagnosis is not based on this chart—or one reading—alone.
Confirm the pattern
Why readings outside the clinic matter
Some people read high in the clinic but normal at home. Others have the opposite pattern. Home readings or a 24-hour monitor can help show what your blood pressure is really doing.
The two patterns you may hear about
White coat hypertension means readings are high in the clinic but normal outside it. Masked hypertension means clinic readings are normal but readings outside it are high.
Measure well at home
Make each number more useful.
01
Use the right monitor
Choose a validated automatic monitor with an upper-arm cuff rather than a wrist device.
02
Settle first
Sit quietly for 5 minutes. Support your back and arm, keep both feet flat, and place the cuff on a bare upper arm at heart level.
03
Take two readings
Take at least two readings, at least 1 minute apart, in the morning before medicines and again in the evening.
04
Repeat the pattern
Do this for 7 days when possible; 3 days is the minimum. Record every reading so the average—not one number—guides the conversation.
Why it happens
For most people, there is no single cause—and no single person to blame.
More than 90% of high blood pressure is primary hypertension: several influences build on one another over time. A smaller group has an identifiable medical cause.
What you inherit
Age, family history, genetics, and early-life factors can change susceptibility.
How daily life adds up
Sodium, low potassium intake, inactivity, weight and insulin resistance, alcohol, nicotine, sleep, and ongoing stress can all contribute.
What deserves a closer look
Kidney or hormone conditions, sleep apnea, and certain medicines, supplements, or substances can raise blood pressure.
Medicines and substances worth reviewing
These can include anti-inflammatory pain medicines such as NSAIDs, estrogen-containing birth control, decongestants, stimulants, steroids, some transplant medicines, certain supplements, cocaine, and methamphetamine. Do not stop a prescribed medicine on your own; bring the full list to your clinician.
When another cause may need investigation
A clinician may look more closely when high blood pressure begins unusually early or suddenly, remains high despite several medicines, or comes with clues such as loud snoring and daytime sleepiness, episodes of sweating and palpitations, or kidney and hormone concerns.
Why it matters
You may feel fine while high pressure quietly strains the body.
The harm usually develops slowly. Treating high blood pressure lowers long-term risk.
Heart & blood vessels
Risk rises for heart disease, heart attack, heart failure, artery damage, and other blood-vessel disease.
Brain
Risk rises for stroke and other damage involving the brain's blood vessels.
Kidneys
Small kidney blood vessels can be damaged, leading to chronic kidney disease.
Eyes
Small blood vessels in the eyes can be damaged, sometimes affecting vision.
First pillar · Medical care
Medical care turns a number into a plan.
The work is not simply choosing a pill. It is confirming the pattern, understanding risk, checking the body, choosing treatment, and returning to see whether it works.
01
Confirm
Repeat accurate measurements and use home or 24-hour readings when appropriate.
02
Understand risk
Review heart and stroke risk, diabetes, kidney disease, cholesterol, smoking, family history, symptoms, medicines, and daily habits.
03
Check the body
Care may include an examination, blood and urine tests, and an electrocardiogram. Extra testing is used when the history suggests another cause or organ damage.
04
Choose treatment
Lifestyle care is recommended for elevated blood pressure and hypertension. Medication is added according to the number, overall risk, other conditions, and clinical judgment.
05
Follow through
Review home readings, side effects, laboratory results, barriers, and progress. Adjust the plan rather than assuming the first version is final.
The decision is individualized
When medicine may begin
Medication is recommended at 140/90 or higher. At 130/80 or higher, it may start sooner for people with cardiovascular disease, prior stroke, diabetes, kidney disease, or higher overall risk. Lower-risk adults may first have 3–6 months of lifestyle treatment, with medicine added if pressure remains high.
Four medication groups
Common first choices
Common first choices are ACE inhibitors, angiotensin receptor blockers, long-acting calcium channel blockers, and thiazide or thiazide-like diuretics. The right choice depends on the person.
Examples include lisinopril or enalapril; losartan or valsartan; amlodipine or extended-release nifedipine; and hydrochlorothiazide, chlorthalidone, or indapamide.
Why blood-pressure targets may differ
Major guidelines do not use exactly the same target for every adult. The best goal balances long-term benefit with side effects, other medical conditions, age, frailty, and personal circumstances.
Second pillar · Lifestyle care
Daily life is treatment—not an optional extra.
Choose the changes with the greatest fit and build from there. Food, movement, sleep, stress, connection, and substances can work together, and they still matter when medication is needed.
01
Eat for blood pressure
Build meals around fruits, vegetables, whole grains, and low-fat dairy, with less saturated fat. This is the core of the DASH pattern. A Mediterranean or plant-forward pattern can also help.
02
Lower sodium
Aim toward 1,500 mg a day when appropriate, stay at or below 2,300 mg, or begin by cutting at least 1,000 mg from your usual intake. Choose more fresh foods, compare labels, reduce portions of high-sodium foods, and use herbs and spices in place of salt.
03
Use potassium safely
Potassium-rich foods can help. Potassium salt substitutes or supplements may be unsafe with kidney disease or medicines that raise potassium, so check before using them.
04
Move each week
Work toward at least 150 minutes of moderate aerobic activity or 75 minutes of vigorous activity each week, plus strength work on at least 2 days. Sit less. If pressure is above 180 systolic or 110 diastolic, control it before vigorous exercise.
05
Protect sleep
Aim for 7–9 hours and pay attention to sleep quality and timing. Loud snoring, daytime sleepiness, resistant blood pressure, or possible sleep apnea deserve a clinical conversation.
06
Make room for recovery
Stress does not make high blood pressure a personal failure. Structured meditation, guided slow breathing, and yoga may help as additions to—not replacements for—medical and lifestyle care.
07
Review substances
Avoid alcohol for blood-pressure prevention or treatment when possible; do not start drinking for heart health. Tobacco, nicotine, and e-cigarettes raise cardiovascular risk. Review cannabis, medicines, and supplements with your clinician too.
A practical place to start
Change the next meal, the next walk, or tonight's bedtime—not your whole life at once.
The plan must fit real life
Food access, medicine cost, work schedules, transportation, housing, stress, and social support can shape what is possible. These are part of blood-pressure care and worth discussing.

Look for a pattern, then adjust the plan.
Blood pressure improves through repetition and follow-up—not through one perfect day or one perfect reading.
About 1 month
After a change
After medicine is started or changed, reassessment is usually needed in about 1 month and monthly until the goal is reached.
Confirm stability
Once at goal
Visits may move to 3-month intervals while the clinician confirms that pressure remains controlled with few side effects.
Keep following
Once stable
For people taking blood-pressure medicine, the interval between office visits should not exceed 6 months once control is stable.
How often should I measure once blood pressure is stable?
Once control has been stable for several months, checking at home on 1–3 days each week is probably sufficient. Follow the schedule set with your clinician.
When to get help
A very high number matters most when the body is in trouble.
A blood pressure above 180 systolic and/or 120 diastolic with signs of sudden organ damage is an emergency.
Seek emergency care
Very high pressure with severe symptoms.
Warning signs include chest pain, severe trouble breathing, sudden weakness or numbness, facial droop, trouble speaking, confusion, severe headache with concerning symptoms, sudden vision changes, fainting, severe illness, or signs of severe illness during pregnancy or soon after pregnancy.
A very high reading without these symptoms still needs prompt clinical guidance. Do not try to manage possible emergency symptoms at home.
Prepare for a visit
Bring the pattern—and the realities around it.
A useful visit includes the readings, the medicines, and the parts of daily life that make the plan easier or harder.
