Overview

Hypertension, or high blood pressure, occurs when the force of blood against artery walls is consistently too high. Often called a silent killer, it can lead to heart disease and stroke if left unmanaged.

Understand this condition

The heart pumps blood through a network of tubes called arteries. Blood pressure measures the resistance the heart faces when pumping that blood. When arteries are narrow or stiff, the heart must work much harder to circulate blood.

Why it happens

It usually progresses as arteries lose elasticity and become narrowed by plaque. This can be triggered by a high-salt diet, lack of exercise, or genetic factors. Over years, the constant pressure causes micro-tears in vessel walls, leading to scarring and further hardening.

Real-world scenarios

  • This often appears as a surprising reading during a routine physical exam.
  • People may notice symptoms only when blood pressure reaches dangerously high levels.
  • This frequently occurs alongside other conditions like high cholesterol or diabetes.

Common vs serious explanations

Common
  • Temporary stress or intense exercise
  • High caffeine consumption recently
  • White coat syndrome during doctor visits
  • Lack of sleep or fatigue
Serious
  • Hypertensive crisis requiring immediate medical attention
  • Underlying kidney failure or renal artery stenosis
  • Preeclampsia during pregnancy
  • Adrenal gland tumors or hormonal disorders

Causes

  • High salt intake
  • Physical inactivity
  • Genetics and family history
  • Excessive alcohol consumption

Risk factors

  • Older age
  • Family history of heart disease
  • Obesity
  • High-stress lifestyle
  • Tobacco use

How it progresses

3 stages
  1. Stage 1 — Early
    Mild or intermittent symptoms; easily mistaken for something minor.
    Often missed
  2. Stage 2 — Progressive
    Symptoms become more frequent or severe.
  3. Stage 3 — Established
    Daily life affected; medical care strongly recommended.

How it's diagnosed

  • Blood pressure cuff readings (sphygmomanometer)
  • Ambulatory blood pressure monitoring
  • Blood and urine tests for organ function
  • Electrocardiogram (ECG)

Treatment options

General educational information only — no dosage advice. Always follow guidance from a qualified clinician.

Medical

  • ACE inhibitors or ARBs
  • Diuretics (water pills)
  • Calcium channel blockers
  • Beta-blockers
Home care
  • Reducing daily sodium intake
  • Regular aerobic exercise
  • Maintaining a healthy body weight
  • Stress management techniques

Complications

  • Long-term damage if untreated

  • Recurrence of hypertension

Prevention

  • Manage stress and sleep
  • Stay hydrated
  • Avoid known triggers
