Hypertension, often called high blood pressure, is a common condition where the force of blood pushing against the walls of your arteries is consistently too high. It’s known as a “silent killer” because it usually has no obvious symptoms but can quietly damage your heart, blood vessels, kidneys, eyes and other organs over time. This blog outlines everything you need to know about hypertension.
What is Hypertension?
The 2024 European Society of Cardiology (ESC) guidelines define hypertension as an office blood pressure (BP) of ≥140/90 mmHg. Readings of 120-139/70-89 mmHg are considered as ‘elevated BP’ because risk starts climbing at these levels.
Causes of Hypertension
The main causes of hypertension can be listed as follows:
- Primary (Essential) Hypertension: It affects about 90-95% of cases and doesn’t have one clear culprit but builds over time from a combination of: genetics (family history of hypertension), age( arteries stiffen with age, specially after 50), lifestyle (consuming too much salt from processed food, sedentary lifestyle, smoking, heavy drinking, stress), obesity, sleep apnea etc.
- Secondary Hypertension: It has a direct cause, affecting about 5-10%
- Kidney Problems: Kidney diseases and renal artery narrowing.
- Hormone Imbalances: Hyperaldosteronism (salt and fluid retention), pheochromocytoma (pumps adrenaline), thyroid hormone imbalance
- Medications: Birth control pills, NSAIDs (pain killers), steroids, decongestants used in cold flu.
- Coarctation of the Aorta: A rare birth defect narrowing the aorta
- Drugs or Toxins: Cocaine, amphetamines
- White-Coat Hypertension: BP spikes from doctor-visit nerves
- Masked Hypertension: BP is high but looks normal in the office
Nursing Assessment for Hypertension
Follow the following steps to assess your blood pressure accurately:
- Preparation: Sit quietly for about 5 minutes in a comfortable chair with your back supported and feet flat on the floor. Avoid caffeine, exercise, or smoking for at least 30 minutes beforehand. Make sure your bladder is empty.
- Positioning: Rest your arm on a flat surface (like a table) so it’s at heart level. Roll up your sleeve or wear a short-sleeved shirt—don’t let tight clothing squeeze your arm.
- Cuff Placement: Use a properly sized blood pressure cuff. It should wrap properly around your upper arm, with the bottom edge about an inch above your elbow. The cuff’s sensor or marker should align with the artery, usually indicated by a line or arrow on the cuff pointing toward the middle of your arm.
- Taking the Measurement: If using an automatic monitor, press the start button and stay still. If it’s manual (with a stethoscope), inflate the cuff by pumping the bulb until the gauge reads about 20-30 mmHg above your usual systolic pressure (or around 160-180 mmHg if you’re unsure). Then slowly release the air while listening for the first heartbeat (systolic) and the last (diastolic) through the stethoscope.
- Reading: Record the numbers—systolic (top number, when the heart beats) over diastolic (bottom number, when the heart rests). For example, 120/80 mmHg is a common healthy reading.
- Repeat: Wait a minute or two, then take a second reading. Average the two for accuracy. Blood pressure can fluctuate, so checking it at the same time daily (like morning or evening) gives a better trend.
Nursing Diagnosis for Hypertension
- Hypertension: An office blood pressure (BP) of ≥140/90 mmHg.
- Elevated BP: Blood pressure of 120-139/70-89 mmHg. Risk starts climbing at these levels.
Nursing Care Plan For Hypertension
Treating hypertension involves a mix of lifestyle changes and, when needed, medication. Here’s a practical strategy:
Lifestyle Adjustments
- Diet: Shift to a heart-friendly eating pattern. Focus on fruits, vegetables, whole grains, lean proteins (fish, poultry), and low-fat dairy. Reduce salt consumption and aim for less than 2,300 mg of sodium daily, ideally 1,500 mg. Avoid processed foods; they’re sodium bombs.
- Exercise: Get moving for at least 150 minutes a week which may be brisk walking, cycling, or swimming (about 30 minutes most days). It strengthens the heart and lowers blood pressure.
- Weight: Losing even 5-10% of your body weight can drop blood pressure noticeably. It’s less about hitting a “perfect” number and more about easing the strain on your system.
- Stress: Chronic stress can spike blood pressure. Techniques like deep breathing, meditation, or even a quick daily walk can dial it down. Aim for at least 7 hours of sleep.
- Limit Alcohol and Quit Smoking: Keep alcohol to moderation (up to one drink a day for women, two for men). Quit smoking entirely.
- Caffeine: Test how it affects you. Some people see a temporary bump in blood pressure, so if you’re sensitive, cut back.
Medication
If lifestyle changes aren’t enough and blood pressure remains above 140/90 mmHg consistently BP lowering medication is necessary. The main groups of these anti-BP medicines are:
- ACE Inhibitors: Relax blood vessels (e.g., lisinopril).
- Diuretics: Flush out excess sodium and water (e.g., hydrochlorothiazide).
- Beta Blockers: Slow the heart rate (e.g., metoprolol).
- Calcium Channel Blockers: Ease vessel tension (e.g., amlodipine).
Lifestyle Modifications for Hypertension
Lifestyle modification includes a healthy diet, regular exercise, weight loss, reducing stress, limiting alcohol and quitting smoking, reducing caffeine intake.
Conclusion
One-third of the world’s adult population has hypertension. Because it usually has no obvious symptoms, but can quietly damage your heart, blood vessels, kidneys, eyes and other organs over time, hypertension is also called a silent killer. Self-measurement of blood pressure after the age of 35 is crucial for early diagnosis and early treatment.

What are the 5 signs of hypertension?
Many people with hypertension don’t notice anything at all until a doctor checks their blood pressure. Regular monitoring is the best way to catch it early. However, some signs might show up, especially as hypertension progresses.
- Headaches: Particularly in the morning or at the back of the head
- Dizziness or lightheadedness
- Nosebleeds: Rare, but they can occur in severe cases.
- Blurred or double vision: This might signal damage to blood vessels in the eyes from prolonged high-pressure
- Shortness of breath: If the heart is strained, breathing might feel harder, especially during activity.
What are the main causes of hypertension?
Causes of hypertension can be classified into two groups:
- Primary (Essential) Hypertension: It affects about 90-95% of cases and doesn’t have one clear culprit but builds over time from a combination of genetics (family history of hypertension), age( arteries stiffen with age, especially after 50), lifestyle (consuming too much salt from processed food, sedentary lifestyle, smoking, heavy drinking, stress), obesity, sleep apnea etc.

- Beta Blockers: Slow the heart rate (e.g., metoprolol).
- Calcium Channel Blockers: Ease vessel tension (e.g., amlodipine).
What are the interventions for hypertension?
The first step in hypertension is to exclude all the secondary causes of hypertension and start lifestyle modification and appropriate antihypertensive medications whenever needed. If the blood pressure is still high despite proper adherence in lifestyle modification and taking at least three antihypertensive medications including an aldosterone receptor antagonist, then interventional therapy may be needed. These interventions include:
- Renal Denervation: A minimally invasive procedure that uses radiofrequency or ultrasound to disrupt overactive sympathetic nerves in the kidneys that can drive hypertension.
- Baroreceptor Activation Therapy: A device implanted to stimulate carotid baroreceptors, tricking the body into lowering blood pressure (rarely used, mostly in trials).
What is the health plan for hypertension?
The primary health plan for hypertension is to:
- Treat underlying causes if there are any
- Lifestyle adjustments
- Antihypertensive medications whenever lifestyle adjustments alone fail to control BP
- İntervention like renal denervation whenever medications fail to maintain optimal BP
What is the management goal of hypertension?
The management goal for hypertension is to lower blood pressure to a safe level to reduce the risk of complications like heart attack, stroke, kidney damage, and vision loss while maintaining overall health and quality of life.
- General Target: For most adults, the goal is to achieve a blood pressure below 130/80 mmHg, as recommended by organizations like the American Heart Association (AHA).
- Older Adults (over 65): A slightly higher target, like <140/90 mmHg, might be acceptable, especially if the patient is prone to side effects (e.g., dizziness from low BP), but 130/80 mmHg is still ideal if tolerated.
- High-Risk Patients: Those with diabetes, heart disease, or chronic kidney disease often aim for <130/80 mmHg to protect organs.
- Very High Readings: For someone starting with severe hypertension (e.g., >180/110 mmHg), the initial goal might be a gradual reduction (e.g., 20-30 mmHg drop) to avoid complications from rapid lowering
Broader goals include reducing cardiovascular risks, preventing end-organ damage (heart, kidney, brain, eyes) and minimizing symptoms.
What are the best practices for hypertension management?
Best practices for hypertension management include adhering to lifestyle adjustments and medications, self-monitoring of BP at regular intervals and consulting an expert whenever the blood pressure is out of track (high or low).
