High Blood Pressure in Adults
A high reading can leave you with questions. Understand what the numbers mean, how to measure them properly and when a family physician can help.
Pressure when your heart contracts.
Pressure when your heart relaxes between beats.
Illustrative example, not a diagnosis or a personal target. Where and how you measure matters.
High blood pressure often causes no obvious symptoms.
Repeated, correctly measured readings help guide assessment.
The aim is to reduce the risk of stroke, heart and kidney disease.
What blood pressure is considered high?
Blood pressure is the force of blood against your artery walls. Hypertension means that pressure remains higher than it should. A single reading cannot tell the whole story: stress, pain, recent activity and measurement technique can affect it.
The two numbers describe different parts of the heartbeat. Either number can be high; you do not need both to exceed a threshold.
A systolic reading of 140 or more, or a diastolic reading of 90 or more, warrants assessment. WHO uses this threshold for hypertension confirmed on different days.
NICE uses a home or daytime ambulatory average of 135 systolic or 85 diastolic or more to support diagnosis alongside raised clinic readings.
AHA/ACC calls 130–139 systolic or 80–89 diastolic Stage 1 hypertension. Assessment and treatment also consider your overall cardiovascular risk.
These are assessment thresholds, not a personal treatment target. Your doctor considers repeated readings, where they were taken, your age, other conditions and treatment tolerance before agreeing on a plan.
When should you see a family physician?
Book a review for a pattern of raised readings, a change in your usual blood pressure or concerns about treatment. You do not need to wait for symptoms.
“My readings are repeatedly high.”
Repeated clinic readings around 140/90 or above, or a raised home average, deserve assessment. Persistent readings around 130/80 also merit discussion, especially with diabetes, kidney disease or previous heart disease or stroke.
“I take tablets, but it is still high.”
Bring your readings and medicine list. A review can check measurement technique, treatment consistency, doses and possible contributing conditions.
“Several health problems overlap.”
Blood pressure may sit alongside diabetes, cholesterol, weight concerns or kidney problems. A family physician can consider these together and coordinate specialist care when needed.
“I am younger, or my readings are changing.”
Persistent high blood pressure deserves attention at any adult age. A new rise, unusually variable readings or dizziness on treatment can also justify a review.

Feeling well does not tell you your blood pressure.
Most people with hypertension have no warning symptoms. Over time, persistently raised pressure can damage blood vessels and increase the risk of stroke, heart attack, heart failure, kidney disease and problems affecting the eyes.
Checking and treating blood pressure is about protecting future health. It is also an opportunity to review cholesterol, diabetes, smoking and other risks that influence the bigger picture.
How to measure blood pressure at home.
Use a validated automatic upper-arm monitor with the correct cuff size. Ask your clinician to check your technique and device. Smartwatch or other cuffless estimates should not replace a validated cuff for treatment decisions.
Prepare before checking
Avoid smoking, caffeine and exercise for 30 minutes beforehand. Empty your bladder and put the cuff on your bare upper arm.
Sit quietly for five minutes
Support your back, keep both feet flat and uncrossed, and rest your arm so the cuff is at heart level.
Take two measurements
Do not talk during the reading. Wait at least one minute between measurements and record both numbers.
Keep a consistent record
Record the date, time and any relevant symptoms. Follow your doctor's schedule rather than repeatedly checking every few minutes.
If your doctor requests a diagnostic home record: a common NICE approach is two readings each morning and evening for at least four days, ideally seven. Keep all readings; the first day's measurements are excluded when calculating the diagnostic average. Do not delay help for very high readings or concerning symptoms while completing a log.
High in the clinic, lower at home? This may be a white-coat effect. The opposite pattern can also occur, called masked hypertension. A home record or a 24-hour ambulatory monitor can help clarify the pattern; your clinician can advise what is appropriate.
What will your doctor assess?
A consultation brings your blood-pressure pattern together with symptoms, medical history, family history, medicines and cardiovascular risk. Weight, activity, salt intake, smoking, alcohol and sleep can be relevant.
Some medicines and products can raise blood pressure, including certain anti-inflammatory painkillers, decongestants, steroids and stimulants. Bring the full list, including supplements. Do not stop a prescribed medicine without advice.
Tests selected for your situation
Assessment may include kidney function and electrolytes, blood glucose or HbA1c, a lipid profile, urine testing and an ECG. Further tests depend on the findings.
Tests are arranged according to clinical need; this does not imply that every test is performed at the clinic.Possible contributing conditions
Kidney disease, sleep apnea and some hormonal conditions may contribute. A young age at diagnosis, a sudden rise or difficult-to-control readings may prompt further investigation or specialist referral.
Lifestyle changes and medicines can work together.
The most useful changes are practical ones you can keep doing. Medication may still be needed, and healthy habits remain valuable when you take it.
Reduce salt, improve food choices
Use less added salt and reduce frequent high-salt foods such as pickles, salty snacks and instant noodles. Include vegetables, fruit, pulses and other minimally processed foods suited to your health needs.
Move regularly and manage weight
Build activity into your routine at a level appropriate for your health. If you are overweight, a realistic weight-management plan can help blood pressure and wider health.
Address the wider risks
Stop smoking or using tobacco, reduce or avoid alcohol, and discuss poor sleep or ongoing stress. Persistent high readings should not be dismissed as “just stress.”
When might medication be recommended?
Your doctor considers confirmed average readings, existing heart or kidney disease, diabetes and overall risk. Medicines are commonly needed for persistent hypertension; some people need more than one. Treatment can also be appropriate at lower readings in certain situations.
Ask what each medicine is for, what side effects to watch for and when you need follow-up or blood tests. If readings improve, keep taking treatment as prescribed: improvement may mean it is working. Do not start, stop or change doses on your own.
Targets differ between guidelines and individuals. Ask for your own clinic and home targets, especially if you are older, have several conditions or feel dizzy on treatment.
Could sleep be part of the picture?
If blood pressure stays high despite treatment, the first steps include checking technique, regular medicine use, doses and other medicines or lifestyle factors.
Obstructive sleep apnea can contribute to difficult-to-control blood pressure. Mention loud snoring, witnessed breathing pauses, morning headaches or excessive daytime sleepiness. A sleep assessment or study may be appropriate, depending on your history.

What patients often ask.
Can I have hypertension without symptoms?
Yes. Many people feel completely well. Symptoms alone cannot tell you whether your blood pressure is high or controlled; measurements and clinical assessment are needed.
Is one high reading enough to diagnose hypertension?
Usually not. If you feel well and the reading is moderately raised, rest and repeat it correctly. Your doctor may request a home record or ambulatory monitoring. Very high readings or concerning symptoms need prompt attention rather than a wait-and-see approach.
Is 130/80 automatically a reason to take tablets?
No single reading determines treatment. Repeated readings, the guideline used, other conditions and cardiovascular risk matter. Discuss a persistent pattern with your doctor rather than starting or stopping medication yourself.
Why is the home threshold different from the clinic threshold?
Measurements taken in different settings can differ. NICE uses a clinic threshold of 140/90 and a home or daytime ambulatory average of 135/85 to help confirm hypertension. An average is more useful than comparing one isolated home reading with one clinic reading.
Can lifestyle changes replace my blood-pressure medicine?
They can improve blood pressure, but many people still need medication. Continue your prescribed treatment and review the results with your doctor before making changes.
Could stress or poor sleep explain my readings?
Stress can temporarily raise readings and affect habits. Persistent hypertension still needs assessment. Snoring, breathing pauses and daytime sleepiness may also suggest sleep apnea, which can contribute to difficult-to-control blood pressure.
