Can I have high blood pressure if I feel great?

Yes, absolutely. Most people with hypertension have no symptoms at all and feel perfectly fine. This is why it is called a silent killer. You can have high blood pressure for years without knowing it, while it quietly damages your heart and kidneys. The only way to know your status is to have your blood pressure measured by a professional.

What does a hypertension headache feel like?

A typical hypertension headache often occurs in the early morning and is felt at the back of the head. It is usually described as a dull, throbbing pain rather than a sharp one. However, most headaches are not caused by high blood pressure. If you have a sudden, "worst ever" headache, you should seek medical help immediately to rule out serious issues.

Does high blood pressure cause nosebleeds?

Generally, high blood pressure does not cause nosebleeds unless the pressure is extremely high. While some people with hypertension may have more frequent nosebleeds, most medical experts believe this is due to damaged vessels rather than the pressure itself. If you have a nosebleed that is difficult to stop and your blood pressure is high, you should contact a healthcare provider.

How often should I check my blood pressure?

If your blood pressure is normal (below 120/80), a checkup once every year or two is usually enough. If you have been diagnosed with hypertension, your doctor may ask you to check it daily or weekly at home using a digital monitor. Regular checks help your doctor determine if your current lifestyle changes or medications are working effectively to protect your health.

Can stress cause temporary symptoms of hypertension?

Stress causes a temporary spike in blood pressure as part of the "fight or flight" response. This may lead to a fast heartbeat, sweating, or a flushed face. However, these symptoms usually fade once the stressor is gone. Chronic stress can contribute to long-term hypertension, but the symptoms people feel during stress are often the body's reaction to adrenaline, not the blood pressure itself.

Are there symptoms of high blood pressure in the eyes?

Early hypertension rarely affects vision. However, long-term or very high blood pressure can cause hypertensive retinopathy. Symptoms include blurred vision, eye swelling, or burst blood vessels in the whites of the eyes. An eye doctor can often detect high blood pressure during an exam by looking at the small vessels in the retina, even if you do not notice any changes.

🩺 Cardiovascular

Hypertension (High Blood Pressure)

Persistently elevated blood pressure that increases long-term cardiovascular risk.

Overview

Hypertension is sustained blood pressure of 140/90 mmHg or higher (or 130/80 by some guidelines). It is usually asymptomatic and is detected on routine measurement. Long-term control reduces stroke, heart attack, kidney disease and dementia risk.

Symptoms

• Often silent — most people have no symptoms
• Occasional headache, especially in the morning
• Visual disturbance in severe cases
• Chest discomfort or breathlessness if complications develop

Risk factors

• Age over 45
• Family history of hypertension
• High salt intake
• Excess body weight
• Physical inactivity
• Excess alcohol
• Chronic kidney disease or diabetes

Causes

• Primary (essential) — no single cause; combination of genetics and lifestyle
• Secondary — kidney disease, endocrine disorders, certain medications, sleep apnea

🚨 Red flags — seek urgent care

• BP ≥180/120 with chest pain, breathlessness, weakness, or visual change — emergency
• Sudden severe headache with very high BP
• New neurological symptoms (weakness, slurred speech)

When to seek care

• Repeated readings ≥140/90 over several days
• Symptoms suggesting end-organ damage
• Side effects from BP medication

Diagnosis

• Clinic BP ≥140/90 mmHg confirmed with ambulatory (ABPM) or home (HBPM) monitoring
• Stage 1 (clinic ≥140/90, ABPM ≥135/85), Stage 2 (clinic ≥160/100), Severe (clinic ≥180/120)
• Baseline tests: U&E, eGFR, urine albumin:creatinine, HbA1c, lipids, ECG, fundoscopy
• Consider secondary causes if young, treatment-resistant, or features suggest endocrine/renal disease

Treatment

• Lifestyle: salt <6 g/day, weight loss, ≥150 min/week activity, alcohol reduction, DASH-style diet
• Step 1 (<55 / not Afro-Caribbean): ACE inhibitor or ARB; otherwise CCB
• Step 2: add the other of ACEi/ARB + CCB, or add thiazide-like diuretic
• Step 3: ACEi/ARB + CCB + thiazide-like diuretic
• Step 4 (resistant): add spironolactone if K+ ≤4.5, or alpha/beta blocker; specialist referral
• Targets: <140/90 in clinic (<135/85 ABPM/HBPM); <130/80 if diabetes or high CV risk

Prevention

• Maintain healthy weight (BMI 18.5–24.9)
• Limit sodium and processed foods; increase potassium-rich fruit and vegetables
• Regular aerobic activity and resistance training
• Limit alcohol (≤14 units/week, spread across the week)
• Avoid tobacco; manage stress and sleep apnoea

Complications

• Stroke and transient ischaemic attack
• Heart attack and heart failure
• Chronic kidney disease
• Aortic aneurysm and dissection
• Hypertensive retinopathy and vision loss
• Vascular dementia

Education & self-care

Lifestyle: reduce salt to <5 g/day, aim for 150 minutes of moderate activity weekly, limit alcohol, maintain a healthy weight, manage stress, and stop smoking. These steps can reduce systolic BP by 10–20 mmHg.

Frequently asked questions

Is hypertension curable?

Primary hypertension is managed, not cured — but it can be controlled with lifestyle changes and medication when needed.

Do I need medication?

It depends on your overall cardiovascular risk and BP level. Lifestyle changes are the first step for most stage 1 hypertension.

How often should I check my BP?

If newly diagnosed, daily for 1–2 weeks then weekly. Once stable, monthly home checks are reasonable.
