Hypertension affects 1 in 4 Indian adults and causes no symptoms until it's dangerous. Learn to understand your BP readings, causes, and how to control it naturally.
High blood pressure (hypertension) is called the "silent killer" because most people have no symptoms until they suffer a heart attack, stroke, or kidney failure. In India, 220 million adults are estimated to have hypertension, yet only 12% have it under control.
Understanding Blood Pressure Numbers
Blood pressure is measured in two numbers: Systolic (top) — pressure when the heart beats; Diastolic (bottom) — pressure when the heart rests between beats.
Blood pressure categories:
- Normal: below 120/80 mmHg
- Elevated: 120–129 / below 80
- Stage 1 Hypertension: 130–139 / 80–89
- Stage 2 Hypertension: 140+ / 90+
- Hypertensive Crisis: above 180/120 — seek emergency care
Causes and Risk Factors
- Excess dietary salt (Indians consume 2–3× the safe limit)
- Overweight or obesity
- Physical inactivity
- Tobacco and alcohol use
- Chronic stress
- Family history
- Diabetes and kidney disease
- Age (risk increases sharply after 40)
High BP usually causes no pain or symptoms. The only way to know is to measure it. Everyone over 18 should check their BP at least once a year.
Dangers of Uncontrolled Hypertension
- Heart attack and heart failure
- Stroke (leading cause in India)
- Kidney disease and failure
- Vision loss
- Peripheral artery disease
- Vascular dementia
Lifestyle Changes That Lower BP
DASH-inspired habits:
- Reduce salt to under 5g/day — stop adding extra salt, avoid pickles/papad/processed foods
- Eat potassium-rich foods: banana, spinach, coconut water, sweet potato
- Exercise 30+ min/day (walking, yoga, swimming)
- Lose weight — even 5kg reduction lowers BP by 5–10 mmHg
- Quit smoking — every cigarette raises BP for 30 minutes
- Limit alcohol — maximum 1 drink/day for women, 2 for men
- Manage stress — deep breathing, meditation, adequate sleep
Medications
If lifestyle changes are insufficient, your doctor may prescribe antihypertensive medications. Common classes include ACE inhibitors, ARBs, calcium channel blockers, beta-blockers, and diuretics. Never stop taking BP medication without consulting your doctor — abrupt withdrawal can be dangerous.
Buy a home BP monitor and check your reading in the morning before eating. Take readings on both arms, sit quietly for 5 minutes first, and share a 2-week log with your doctor.
