High blood pressure—hypertension—is so common that many people discover it only during a routine check. That quiet start is exactly why screening matters: untreated pressure strains arteries, heart, kidneys, eyes, and brain over years.
What counts as high blood pressure?
Blood pressure has two numbers: systolic (pressure when the heart beats) and diastolic (between beats). Clinicians use thresholds that may vary slightly by country and age. If your readings are repeatedly above your clinician’s target, you may be diagnosed with hypertension even when you feel fine.
Symptoms: often none until late
Most people have no obvious symptoms. Severe or sudden high pressure can cause headaches, vision changes, chest pain, or shortness of breath—treat these as urgent. Do not wait for symptoms to justify a check.
Common causes and risk factors
- Age and family history
- Excess salt, low activity, overweight
- Heavy alcohol, smoking, poor sleep
- Chronic kidney disease, thyroid or adrenal disorders
- Some medicines (always review with a prescriber)
How hypertension is diagnosed
Diagnosis usually requires several readings over time—in clinic, at home, or with ambulatory monitoring. Home cuffs help but must be validated and used with correct cuff size. Bring a log to appointments.
Treatment and lifestyle
First steps often include salt reduction, regular movement, weight management, sleep, and limiting alcohol. When lifestyle alone is not enough, evidence-based medicines are commonly prescribed—never stop or change doses without medical advice.
Prevention that actually helps
- Know your numbers yearly (more often if advised)
- Follow a heart-friendly eating pattern rich in vegetables and whole grains
- Stay active most days of the week
- Manage stress and sleep—not as a cure-all, but as real contributors
Questions to ask your doctor
- What is my target blood pressure based on my age and conditions?
- Should I monitor at home, and which cuff do you recommend?
- Could any of my current medicines raise pressure?
- When do I need blood tests or kidney checks?
- What symptoms mean I should seek urgent care?
