Hypertension
Managing hypertension starts with understanding it. Our resources provide key information about hypertension, its risks, and how to monitor and control it. Discover tips and lifestyle changes to help manage your blood pressure and improve your health
Hypertension
What is hypertension?
Hypertension happens when blood pressure stays at a high level constantly.
Why is it dangerous?
Consistently high blood pressure can notably impair your health, potentially damaging your blood vessels and organs, notably your heart, brain, eyes, and kidneys. It’s essential to understand the stages of hypertension.
What causes hypertension?
Hypertension can arise from several causes, including age, family history, obesity, and unhealthy lifestyle habits such as smoking and excessive alcohol consumption.
Blood Pressure + Measurements
What is blood pressure?
Blood Pressure is the force your blood exerts on the arteries when your heart pumps.
How do you measure it?
Blood pressure (BP) measurement is displayed as two numbers. BP readings below 120/80 mmHg* are ideal for heart health and well-being.
Systolic pressure, which is the top number (here, 120), represents the level of arterial pressure when your heart is beating.
Diastolic pressure, the bottom number (here, 80), signifies the pressure when your heart is stopped between beats.
* “mmHg” stands for millimeters of mercury. It’s an old unit of measurement used to express blood pressure. Early blood pressure devices used mercury columns to measure the force of blood against the walls of the arteries.
Stages of Hypertension – Why is it a health problem?
Normal Blood Pressure (Exactly or less than 120/80 mmHg*)
Blood pressure is within a healthy range, allowing the heart and blood vessels to function efficiently. Organs such as the brain, kidneys, and heart experience no additional stress, promoting overall good health and quality of life.
Elevated Blood Pressure (120-129/80 mmHg)
-
-
- Blood pressure is slightly elevated but not yet in the danger zone. While there may be no immediate damage, prolonged pressure at this level places unneeded stress on blood vessels, gradually increasing the risk of heart disease and organ strain.
-
Stage 1 Hypertension (130-139/80-90 mmHg)
Blood pressure is consistently elevated, and organs like the heart and kidneys begin to experience strain. If this persists, there’s an increased risk of developing heart disease, stroke, or kidney problems in the future.
Stage 2 Hypertension (140/90 mmHg or higher)
Blood pressure is dangerously high, causing significant stress on blood vessels. This can lead to gradual damage to vital organs like the heart, kidneys, and brain, potentially decreasing life quality and increasing the risk of life-threatening conditions.
Hypertensive Crisis (180/120 mmHg or higher)
Blood pressure has reached emergency levels and can cause immediate damage to organs. The risk of heart attack, stroke, or kidney failure is extremely high, and immediate action is required to prevent serious harm.
*As per American Health Association (AHA) standards, low blood pressure is a measurement below 90/60 mmHg.
Normal Blood Pressure
Blood pressure is normal.
The heart pumps blood efficiently, delivering oxygen and nutrients to vital organs like the brain, kidneys, and muscles while minimizing stress on blood vessels.
Doctor’s recommendation: Continue healthy lifestyle habits.
Pre-Hypertension
Blood pressure is slightly elevated but not yet in the hypertension range.
Doctor’s recommendation: Focus on lifestyle changes to prevent progression to hypertension.
Stage 1 Hypertension
Blood pressure measurements consistently fall between 130/80 mmHg and 139/89 mmHg, indicating the initial hypertension stage.
Doctor’s recommendation: Lifestyle changes and medication may be required to lower blood pressure.
Stage 2 Hypertension
Blood pressure measurements consistently fall higher than 140/90 mmHg, indicating a more severe level of hypertension that requires urgent management to prevent damage to vital organs.
Blood pressure is dangerously high, causing significant stress on blood vessels. This can lead to gradual damage to vital organs like the heart, kidneys, and brain, potentially decreasing life quality and increasing the risk of life-threatening conditions.
Doctor’s recommendation: Stronger or multiple medications and lifestyle changes are often necessary to bring blood pressure down to safer levels.
Stage 3 Hypertensive Crisis
Blood pressure measurements consistently fall higher than 140/90 mmHg, indicating a more severe level of hypertension that requires urgent management to prevent damage to vital organs.
Blood pressure is dangerously high, causing significant stress on blood vessels. This can lead to gradual damage to vital organs like the heart, kidneys, and brain, potentially decreasing life quality and increasing the risk of life-threatening conditions.
Doctor’s recommendation: Stronger or multiple medications and lifestyle changes are often necessary to bring blood pressure down to safer levels.
Healthy Lifestyle Habits
Eat a balanced diet: Focus on fruits, vegetables, whole grains, and low-fat dairy; limit salt and saturated fats.
Exercise regularly: Aim for at least 5 sessions of moderate-intensity activity (like brisk walking) per week.
Manage stress & sleep well: Practice relaxation techniques, get 7-9 hours of sleep, and manage stress through activities like meditation or hobbies.
Healthy Lifestyle Habits
Improve diet: Reduce salt intake, eat more fresh foods like fruits, vegetables, and whole grains, and avoid saturated fats.
Increase physical activity: Go for at least 150 minutes of moderate aerobic exercise (e.g., brisk walking, swimming) weekly. 30 minutes x 5 times weekly.
Reduce stress & maintain sleep: Practice relaxation techniques and ensure good quality and duration of sleep each night to help regulate blood pressure.
Healthy Lifestyle Habits
Medications: Common prescriptions include thiazide diuretics, ACE inhibitors, or calcium channel blockers to help lower blood pressure.
Diet modifications: Continue reducing salt intake, and choose fresh foods like fruits, vegetables, and lean proteins instead of processed foods.
Regular exercise: 30 minutes x 5 times weekly of moderate physical activity per week is very important. Walking, cycling, or swimming are all suitable activities to help reduce BP.
Regular monitoring of blood pressure: Track improvements and adjust medication as needed.
Lifestyle Changes & Medication
Medications: Common prescriptions include thiazide diuretics, ACE inhibitors, or calcium channel blockers to help lower blood pressure.
Lifestyle modifications: Continue with the same recommendations from Stage 1 Hypertension
Weight loss: For those who are overweight, even a tiny amount of weight loss can significantly impact lowering blood pressure.
Frequent monitoring of blood pressure: home blood pressure monitoring and regular follow-ups with the doctor are key.
Stage 2 hypertension is more serious and can lead to severe complications if not managed properly. Therefore, patients must follow a strict treatment plan and communicate closely with their healthcare provider.
Emergency Treatment and Ongoing Care
Emergency Medications + Hospitalization: Doctors may use intravenous (IV) medications to lower blood pressure rapidly. Hospitalization is very likely. Common drugs include nitroglycerin, labetalol, and sodium nitroprusside.
Complications: Doctors will check for complications such as heart attack, stroke, or kidney failure, which can be caused or worsened by extremely high blood pressure.
Long-Term Management After Crisis:
Refer to lifestyle changes taken to manage Stage 1 and Stage 2 Hypertension
A hypertensive crisis is a life-threatening condition that requires swift and aggressive treatment. After the emergency is resolved, patients need to adhere to a comprehensive care plan, including medication and lifestyle changes, to reduce the risk of another crisis and prevent serious complications like heart attack or stroke.
Who should monitor blood pressure at home?
Home monitoring is recommended for all people with high blood pressure to help their healthcare professionals know if treatments are working. Home monitoring does not replace regular doctor visits.
Choose the correct device for an accurate reading at home and then learn to take good measurements.
1. The Right Device:
> Use an automatic, cuff-style monitor for the upper arm (wrist and finger monitors are less accurate).
> Check that the monitor is validated, especially for seniors, pregnant individuals, or children. Ask your doctor or check options on validatebp.org.
> Get the correct cuff size: measure your upper arm to ensure a proper cuff fit; an incorrect size affects accuracy.
> Have your device checked: take your new monitor to a healthcare appointment to confirm it gives accurate readings. Plan to bring it once a year for a check-up.
2. Take Good Measurements:
> Prepare: avoid caffeine smoking, and exercise for 30 minutes before measuring. Empty your bladder beforehand.
> Follow the correct measurement steps: sit with your back supported, feet flat, and arm at heart level on a table. Don’t talk, cross your legs, or move.
> Record Consistent Results: take readings at the same time each day. Do two measurements one minute apart, and keep a record. Some monitors allow you to store or upload readings for easy tracking.
Did you know? White coat syndrome, or white coat hypertension, happens when you get a high blood pressure reading in a doctor’s office and a normal reading at home. The term comes from the tradition of doctors wearing white coats. For some people, the anxiety of being around doctors can make their blood pressure rise. Most people don’t need treatment if their blood pressure is normal at home.
Self Care and Monitoring
💪 Proactive Self-Care: Managing hypertension means taking charge of your health and well-being by consistently practicing healthy habits to keep blood pressure under control.
⏲️ Consistency Challenges: It can be difficult for some people, especially those with busy lives or limited access to resources, like healthy, fresh foods and community support, to stay consistent with their self-care routines.
🤷 What works for you? Self-care is personal—things like relaxation methods and food preferences vary widely from one person to another.
🕯️Stress Management: Managing stress is essential for controlling blood pressure. Techniques like mindfulness, meditation, and breathing exercises can help. A healthy diet and regular physical activity are key, too – it’s easier to care for your mental health when the body feels good – that’s the mind-body connection.
🍲 Diet and Nutrition: Eating a balanced diet, rich in fruits and vegetables and low in sodium, is crucial for managing hypertension.
DASH Diet – What You Need to Know
What is it?
The DASH diet stands for “Dietary Approaches to Stop Hypertension.” It was created to help lower high blood pressure and is recommended by the U.S. National Heart, Lung, and Blood Institute.
Why was it designed?
The DASH diet was designed based on research showing that certain foods can help lower blood pressure. It is also a heart-healthy eating plan recommended for the general public.
What do you eat?
The DASH diet focuses on:
> Fruits and vegetables
> Whole grains
> Low-fat dairy products
> Lean meats, fish, and poultry
> Nuts, beans, and seeds
> It LIMITS sugar-sweetened foods, red meat, and added fats.
Why is it important?
The DASH diet has been shown to lower blood pressure and improve overall heart health. It’s a balanced eating method that can help with weight management and other conditions like diabetes.
💡A closer look at treatment protocols
Treatment protocols are the guidelines or strategies healthcare providers follow to treat patients.
When developing a personalized plan to manage hypertension, healthcare providers typically consider the following factors:
Initial Evaluation and Risk Assessment:
> Start with getting an accurate blood pressure reading! (determine whether the patient is in Hypertension Stage 1 or 2).
> Look at other cardiovascular risk factors (such as age, family history, smoking, and diabetes).
> Look into the patient’s daily habits, such as diet, physical activity, alcohol intake, smoking, stress levels, and sleep quality.
Lifestyle Changes:
> Dietary Changes: Recommending a heart-healthy diet such as the DASH diet and limiting processed foods.
> Physical Activity: Encouraging regular exercise, such as moderate-intensity aerobic exercise.
> Weight Management: Weight loss for overweight individuals has been shown to reduce blood pressure.
> Stress Management: techniques such as meditation, deep breathing, or yoga also help to reduce stress-induced hypertension.
Pharmacological Treatment (Medication):
Stage 1 Hypertension: Doctors may often recommend lifestyle changes as the primary intervention. However, if there are additional risk factors (like diabetes or heart disease), medications may be prescribed.
Common medications include:
> ACE inhibitors (e.g., lisinopril)
> Calcium channel blockers (e.g., amlodipine)
> Thiazide diuretics (e.g., hydrochlorothiazide)
Stage 2 Hypertension (140/90 mmHg or higher): This stage almost always requires medication alongside lifestyle changes. Often, combination drug therapy is introduced (e.g., two or more medications).
> Combination therapy: Single-pill combinations may include a diuretic with an ACE inhibitor or a calcium channel blocker to reduce the pill burden and increase adherence.
Special Considerations:
> Elderly Patients: The protocols for older patients may have more relaxed blood pressure targets, especially if they have other frailties.
> High BP in combination with other health conditions: If patients have other health conditions like chronic kidney disease or heart failure, the choice of medication may vary. For example, beta-blockers may be used more frequently in patients with coronary artery disease.
Ongoing Monitoring and Adjustments:
> Regular Blood Pressure Monitoring: Patients must regularly monitor their blood pressure at home and check in with their healthcare provider to adjust medication if required.
> Follow-up Appointments: Ensuring the treatment is working effectively or making adjustments based on side effects or changes in health status.
FAQ
Can hypertension be reversed?
Yes, in many cases, hypertension can be managed and even reversed through lifestyle changes such as a balanced diet, regular exercise, and weight loss for those who are overweight. These adjustments can help reduce blood pressure naturally and decrease the risk of needing medication.
What are the first signs of high blood pressure?
High blood pressure is often called a “silent killer” because it usually has no noticeable symptoms! However, in some cases, people may experience headaches, shortness of breath, or nosebleeds, but these signs often occur when blood pressure is dangerously high.
How often should I check my blood pressure?
Healthy individuals should consider checking their blood pressure at least once a year, or as their doctor recommends, to ensure levels remain within a safe range.
For people with hypertension or at risk of it, checking blood pressure at home daily or weekly is recommended. If blood pressure is well-managed, healthcare providers may suggest less frequent monitoring, such as monthly checks.
How do I know if I’m in the at-risk group for hypertension?
You may be at higher risk for hypertension if you have a family history of high blood pressure, are overweight, lead a sedentary lifestyle, consume too much salt, or experience high stress. Some studies show that African American and Latino populations are also at higher risk, possibly due to genetic, socioeconomic, and environmental factors. Conditions like diabetes can further increase the risk of hypertension.
Can I manage hypertension without medication?
Yes, many people manage hypertension without medication through lifestyle changes, including a low-sodium diet, regular physical activity, stress reduction, and weight management. However, in some cases, medication may still be necessary.
What about extremely low blood pressure (hypotension)?
Low blood pressure (90/60 mmHg or lower) is usually not dangerous, but it may need treatment if it causes dizziness, fainting, or weakness. Causes of hypotension vary and can include dehydration, certain medications, or health conditions requiring medical attention.
What if my bottom blood pressure reading (diastolic pressure) is normal, but the top number (systolic pressure) is high?
The bottom blood pressure reading is sometimes normal (less than 80 mm Hg), but the top number is high. This is called isolated systolic hypertension. It’s a common type of high blood pressure in people over 65.
What is the connection between cholesterol and high blood pressure?
High cholesterol causes plaque build-up in the arteries, making them narrow and forcing the heart to pump harder, raising blood pressure. When high cholesterol and high blood pressure occur together, they significantly increase the risk of heart disease, heart attack, and stroke, as both conditions strain the heart and blood vessels.
