Academy topic
Hypertension
Blood pressure understood through medicine and daily life.
This page explains high blood pressure in a calm, practical way. It starts with the main ideas. You can then learn more about diagnosis, treatment, daily habits, follow-up, and questions to ask your physician.
Epidemiology
High blood pressure is common. It often causes no symptoms, and many people do not yet have it under control.
U.S. adults
About 45 out of every 100 adults have high blood pressure.
Adults 65 and older
More than 3 out of every 4 are affected.
Control
Only about 23 to 24 out of every 100 adults with high blood pressure reach the recommended goal of 130/80 millimeters of mercury (mmHg).

Patient guide
Explore the essentials.
Learn what high blood pressure is, how it is found, and how care may change over time.
What is hypertension?+
Hypertension is the medical name for blood pressure that stays higher than recommended. Blood pressure is the force of blood pushing against artery walls.
A blood pressure reading has two numbers. The top number is the pressure when the heart squeezes. It is called systolic pressure. The bottom number is the pressure when the heart relaxes. It is called diastolic pressure.
High blood pressure is common and often causes no symptoms. Even when a person feels well, it can raise the risk of serious health problems over time.
How blood pressure works+
Blood pressure depends mainly on how much blood the heart pumps and how much resistance the arteries create.
Heart
The heart pushes blood forward with each beat.
Blood vessels
Arteries tighten and relax as blood moves through them. They can also become stiffer over time.
Kidneys
The kidneys help control salt, water, and long-term blood pressure.
Blood pressure also has a daily rhythm. For many people it falls during sleep and rises again in the morning.
Why it happens+
Most high blood pressure develops from several factors working together. This is called primary, or essential, hypertension. It does not have one single cause.
age, family history, and genetics
eating too much sodium or not getting enough potassium
physical inactivity, excess weight, and insulin resistance
alcohol, tobacco, nicotine, and other substances
ongoing stress, poor sleep, and obstructive sleep apnea
certain medicines and supplements
social or environmental conditions that make healthy care harder to reach
Sometimes another health condition, medicine, or substance causes high blood pressure. This is called secondary hypertension. Your physician decides when testing for these causes is needed.
Symptoms and signs+
Most people with high blood pressure have no symptoms. It is often found during a routine blood pressure check.
Some people with blood pressure that stays high or becomes very high may have headaches, dizziness, vision changes, nosebleeds, or shortness of breath. These symptoms can have many causes. New, severe, or lasting symptoms should be discussed with a clinician.
What can happen over time+
High blood pressure usually causes harm slowly. Over many years, extra pressure can strain blood vessels and organs even when a person feels well.
Heart and blood vessels
It can raise the risk of heart disease, heart attack, heart failure, and other blood-vessel disease.
Brain
It can raise the risk of stroke and other problems involving brain blood vessels.
Kidneys
It can damage small kidney blood vessels and lead to long-term kidney disease.
Eyes
It can damage the small blood vessels in the eyes.
High blood pressure can be treated. Lowering it can lower long-term risk.
When to seek urgent care+
Very high blood pressure with certain symptoms may be an emergency. Seek urgent medical care when high blood pressure occurs with:
- chest pain
- severe trouble breathing
- weakness, numbness, facial droop, trouble speaking, or another sudden change involving the brain or nerves
- confusion
- severe headache with concerning symptoms
- sudden vision changes
- fainting or severe illness
- signs of severe illness during pregnancy or soon after pregnancy
Do not try to manage possible emergency symptoms at home.
How hypertension is diagnosed+
Diagnosis starts with an accurate blood pressure check. The cuff must fit correctly. The person should rest first, keep both feet flat, and support the back and arm. A single reading may not show the full pattern.
A diagnosis usually requires high readings on more than one occasion. Readings taken at home or with a monitor worn for 24 hours can help confirm what happens outside the clinic.
| Pattern | Meaning |
|---|---|
| White coat hypertension | Blood pressure is high in the clinic but normal outside the clinic. |
| Masked hypertension | Blood pressure is normal in the clinic but high outside the clinic. |
Living with hypertension+
High blood pressure care usually requires follow-up. After medication is started or changed, another visit is often needed in about one month. Follow-up continues until blood pressure reaches the goal set with your clinician.
Visits may be spaced farther apart once blood pressure is stable. Home readings can help you and your physician see patterns. Your clinician should explain how often to check at home and when to return.
Medication treatment+
Medication can help lower blood pressure and long-term health risks. Whether to start it depends on the blood pressure level, overall risk, other health conditions, and physician judgment. The full Treatment section explains how medication and daily habits work together.
Lifestyle treatment+
Daily habits are a core part of preventing and treating high blood pressure. Changes should be practical, safe, and matched to the person. The full Treatment section explains the main areas to consider.
Questions to ask your physician+
- Is my high blood pressure diagnosis confirmed?
- Should I check my blood pressure at home or use a 24-hour monitor?
- What blood pressure goal is right for me?
- What is my overall risk for heart and blood-vessel disease?
- Do I need medication now, or could I start with daily habit changes and close follow-up?
- Which daily changes are most important for me?
- Could a medicine, supplement, alcohol, nicotine, cannabis, or another substance be raising my blood pressure?
- Should I be checked for sleep apnea or another cause of high blood pressure?
- What blood or urine tests do I need?
- What side effects should I watch for if I start medication?
- When should I return for follow-up?
- When should I seek urgent care?
Frequently asked questions+
Can I have high blood pressure if I feel fine?
Yes. High blood pressure often causes no symptoms. Measuring it is the main way to find it.
Does one high reading mean I have hypertension?
Not always. Blood pressure changes from moment to moment. Diagnosis usually requires careful readings on more than one occasion. Home or 24-hour monitoring may also be used.
Will daily habit changes be enough?
Sometimes. Many people need both daily habit changes and medication. The plan depends on the blood pressure level, overall risk, other health conditions, and physician judgment.
Is potassium always helpful?
No. Potassium from food can help lower blood pressure. Potassium supplements and potassium-based salt substitutes can be unsafe for people with kidney disease or those taking certain medicines.
Can I exercise if my blood pressure is high?
Regular movement helps many people with high blood pressure. If blood pressure is very high, it should generally be controlled before vigorous exercise.
Treatment
Two pillars, one plan.
Contrada treats high blood pressure through traditional medicine and lifestyle medicine together. The balance depends on the person, blood pressure pattern, overall risk, safety, and physician judgment.
Traditional medicine treatment
Measurement, risk, medication, and follow-up.
Care may include more accurate blood pressure checks, home monitoring, medication, testing for other health risks, and follow-up. A physician may also look for another cause when the history or blood pressure pattern suggests one.
Some people need medication soon. Others may begin with daily habit changes and close follow-up when their blood pressure and overall risk make that safe.
Common first-line medication classes include:
- angiotensin-converting enzyme (ACE) inhibitors
- angiotensin receptor blockers (ARBs)
- long-acting calcium channel blockers
- thiazide or thiazide-like diuretics, sometimes called water pills
Medication choice depends on the individual person and should be made with a physician.
Lifestyle medicine treatment
Daily life as part of the treatment plan.
Lifestyle medicine is a core part of preventing and treating high blood pressure. It should be practical, safe, and matched to the person.
Nutrition
The Dietary Approaches to Stop Hypertension (DASH) eating pattern emphasizes fruits, vegetables, whole grains, and other nutrient-rich foods. Reducing sodium may help. Potassium decisions require care for some people.
Movement
Regular aerobic activity and strength training can help. Ask for medical guidance before vigorous exercise when blood pressure is very high.
Sleep
Sleep length, sleep quality, insomnia, shift work, and obstructive sleep apnea can affect blood pressure.
Stress and recovery
Ongoing stress, depression, anxiety, financial strain, discrimination, and other pressures can make blood pressure harder to control.
Relationships and community
Support, access to care, food security, transportation, medicine cost, and the ability to understand health information can affect the plan.
Substances
Alcohol, tobacco, nicotine, cannabis, medicines, and supplements should be reviewed carefully.
