High blood pressure, commonly known as hypertension, is often called the “silent killer” because it typically presents no obvious symptoms until it causes serious health complications. Many adults and even children remain unaware they have high blood pressure until routine health checks detect it. In India, the prevalence of hypertension is rising alarmingly, making awareness and early intervention crucial.
Did you know? According to the World Health Organization (WHO), approximately 1 in 3 adults in India has high blood pressure, and nearly half of them are unaware of their condition.
At Deepa Hospital, a trusted multispeciality hospital ayapakkam, we emphasize early detection, education, and proactive management of blood pressure for patients of all ages, including children and adolescents.
What Is High Blood Pressure?
Blood pressure is the force of blood pushing against the walls of arteries as the heart pumps. It is measured in millimeters of mercury (mmHg) and recorded with two numbers:
- Systolic Pressure (upper number): Pressure in the arteries when the heart beats.
- Diastolic Pressure (lower number): Pressure in the arteries when the heart rests between beats.
Normal vs High Blood Pressure:
| Category | Systolic (mmHg) | Diastolic (mmHg) |
|---|---|---|
| Normal | <120 | <80 |
| Elevated | 120–129 | <80 |
| Hypertension Stage 1 | 130–139 | 80–89 |
| Hypertension Stage 2 | ≥140 | ≥90 |
Regular monitoring is vital because untreated hypertension can silently damage vital organs, including the heart, kidneys, and brain.
Types of High Blood Pressure
- Primary (Essential) Hypertension
- Accounts for 90–95% of all hypertension cases.
- Develops gradually over years due to lifestyle, diet, stress, and genetic factors.
- Secondary Hypertension
- Caused by underlying medical conditions such as kidney disease, hormonal disorders, or certain medications.
- Can occur suddenly and is often more severe than primary hypertension.
- Pediatric Hypertension
- High blood pressure in children and adolescents is increasingly common due to obesity and sedentary lifestyles.
- Early identification is critical to prevent long-term cardiovascular risks.

Prevalence of High Blood Pressure in India
Hypertension is a growing public health challenge in India:
- Adults: Approximately 33.9% of adults in Tamil Nadu have high blood pressure.
- Children & Adolescents: Around 7–10% of children show elevated blood pressure readings, often linked to obesity and poor lifestyle habits.
- Urban vs Rural: Urban areas like Chennai report higher prevalence due to sedentary lifestyles and high-stress environments.
Insight: Early detection in children and adults reduces long-term complications like heart disease, stroke, and kidney failure.
Causes and Risk Factors
High blood pressure can be triggered by multiple factors, often a combination of genetics and lifestyle:
- Age: The risk rises with age, especially after 40.
- Family History: Genetics plays a significant role; children of hypertensive parents are more likely to develop it.
- Obesity & Sedentary Lifestyle: Excess weight and inactivity increase heart strain and blood pressure.
- High Salt Diet: Sodium-rich foods contribute to fluid retention and elevated BP.
- Stress & Mental Health: Chronic stress releases hormones like cortisol and adrenaline, which elevate blood pressure.
- Alcohol & Tobacco: Both increase blood pressure and damage blood vessels.
- Underlying Health Conditions: Kidney disease, diabetes, and hormonal disorders can trigger hypertension.
Pro Tip: Regular lifestyle checks, a healthy diet, and monitoring stress levels can significantly reduce risk.
Signs and Symptoms: Why It’s Called the “Silent Killer”
High blood pressure often shows no symptoms in the early stages. However, chronic hypertension may eventually present:
- Headaches or dizziness
- Shortness of breath
- Nosebleeds
- Fatigue or confusion
- Visual disturbances
Because symptoms are often subtle, regular blood pressure monitoring is crucial, especially for adults and children at risk.
Complications of Untreated Hypertension
Untreated or poorly managed high blood pressure can have serious consequences:
- Heart Attack & Heart Failure: The heart works harder, leading to left ventricular hypertrophy and cardiac complications.
- Stroke: Increased pressure can cause artery damage or clot formation.
- Kidney Disease: High BP damages kidney filtration, potentially causing renal failure.
- Vision Loss: Hypertensive retinopathy can lead to blindness if untreated.
- Cognitive Decline: Chronic hypertension is linked to memory loss and dementia.
Diagnosis and Monitoring
Accurate diagnosis requires consistent measurements:
- Clinical Readings: Blood pressure taken during clinic visits.
- Home Monitoring: Using validated home BP monitors ensures accurate tracking.
- Ambulatory BP Monitoring (ABPM): 24-hour monitoring gives a detailed picture of BP fluctuations.
- Lab Tests: Blood tests, urine tests, and ECG may be conducted to assess organ function.
Managing High Blood Pressure: Lifestyle and Medical Interventions
Lifestyle Modifications
- Balanced Diet (DASH or Mediterranean Diet):
- Reduce salt intake to <5g/day.
- Include vegetables, fruits, whole grains, lean proteins.
- Limit processed foods and sugary drinks.
- Regular Physical Activity:
- 30–45 minutes of moderate exercise, 5 days a week.
- Activities like brisk walking, yoga, swimming, and cycling.
- Weight Management:
- Achieve a healthy BMI.
- Even 5–10% weight loss can reduce BP significantly.
- Stress Management:
- Meditation, deep breathing exercises, mindfulness.
- Engage in hobbies or counseling if needed.
- Avoid Smoking & Limit Alcohol:
- Smoking damages arteries; alcohol raises BP.
- Moderation or cessation is key.
Medical Management
- Medications: ACE inhibitors, beta-blockers, calcium channel blockers, or diuretics may be prescribed.
- Regular Monitoring: Follow-up every 3–6 months for controlled hypertension.
- Combination Therapy: Sometimes, more than one drug is needed for effective BP control.

High Blood Pressure in Children: What Parents Should Know
Pediatric hypertension is on the rise due to lifestyle changes. Early detection and management prevent adult cardiovascular risks.
Key Points for Parents:
- Monitor BP during regular pediatric visits.
- Encourage physical activity (1 hour/day for children).
- Maintain a healthy diet low in processed foods and high in fruits and vegetables.
- Reduce screen time and promote outdoor activities.
- Educate children about healthy habits early.
