High blood pressure often has no noticeable symptoms until it causes severe damage to arteries, the heart, brain, and kidneys. Nearly one in three adults in urban India has high blood pressure, and over half are unaware of their condition.

Normal < 120 mmHg and < 80 mmHg
Elevated 120 – 129 mmHg and < 80 mmHg

Stage 2 Hypertension ≥ 140 mmHg or ≥ 90 mmHg

  1. Slash Sodium Intake: Limit table salt to less than 1 teaspoon (2,300 mg sodium) daily; avoid processed pickles, papads, and namkeens.
  2. Boost Potassium-Rich Foods: Bananas, coconut water, spinach, and sweet potatoes help balance sodium levels in vascular smooth muscle.
