Hypertension in India

Hypertension in India 

  • High blood pressure (BP) is a major public health problem in India and its prevalence is rapidly increasing among both urban and rural populations.1, 2 In fact, hypertension is the most prevalent chronic disease in India.
  • The prevalence of hypertension ranges from 20-40% in urban adults and 12-17% among rural adults. The number of people with hypertension is projected to increase from 118 million in 2000 to 214 million in 2025, with nearly equal numbers of men and women.3  
  • A survey of 26,000 adults in South India showed a hypertension prevalence of 20% (men 23% and women 17%) but 67% of those with hypertension were unaware of their diagnosis. Majority of hypertensive subjects still remain undetected and the control of hypertension is also inadequate. This calls for urgent prevention and control measures for hypertension.4 See Figure 107.
  • Recent (2012) studies show that for every known person with hypertension there are two persons with either undiagnosed hypertension or prehypertension (Figure 106).8
  • Reducing blood pressure can decrease cardiovascular risk and this can be achieved by lifestyle measures in mild cases and should be the initial approach to hypertension management in all cases. This includes dietary interventions weight reduction, tobacco cessation, and physical activity.1
  • Dietary interventions include; reducing salt, increasing potassium, and alcohol avoidance. But unlike in Western countries, stress management is often given greater emphasis in India.
  • A number of safe and effective medications are available for treatment of high blood pressure. These include older molecules such as thiazide diuretics, beta-blocking agents, calcium channel blockers (CCB) and newer molecules, such as, angiotensin converting enzyme (ACE) inhibitors, and angiotensin receptor blockers (ARB). In view of the recent clinical trials data, some international guidelines suggest that CCB, ACE inhibitors or ARB and not beta-blockers or diuretics should be the initial therapy in hypertension management.1 The former however, are much more expensive and beyond the affordability in many poor income countries.
  • Because of the heightened risk, the recommended targets are lower for all Indians<130/85 and <120/80 for those with diabetes or heart failure.5, 6
  • Comprehensive hypertension management should focus not only on reducing the blood pressure, but reducing the cardiovascular risk by lifestyle measures, lipid management, smoking cessation, and regular exercise.1, 7

One thought on “Hypertension in India

  1. blood pressure generally flows with 160-170 / 90- 95 in age of 32 years (female). No salt intake with normal weight and no smoking.

    Q. What are reasons for such high blood pressure and how it can be prevented ?
    Q. What are range for such high blood pressure according to age ?
    Q. Is there any medicines/ measures to cure high blood pressure ?
    Q. Whether it increases according to increase of age ?
