Why Hypertension is Called the "Silent Killer"
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.
Blood Pressure Categories (AHA Guidelines)
| Category | Systolic (Upper #) | Diastolic (Lower #) |
|---|---|---|
| Normal | < 120 mmHg | and < 80 mmHg |
| Elevated | 120 – 129 mmHg | and < 80 mmHg |
| Stage 1 Hypertension | 130 – 139 mmHg | or 80 – 89 mmHg |
| Stage 2 Hypertension | ≥ 140 mmHg | or ≥ 90 mmHg |
| Hypertensive Crisis (Emergency) | > 180 mmHg | and/or > 120 mmHg |
Symptoms When Blood Pressure Reaches Critical Levels
- Severe morning headaches localized to the back of the head.
- Shortness of breath during routine activities.
- Nosebleeds without apparent nasal injury.
- Blurred vision or visual floating spots.
- Chest tightness or irregular palpitations.
The DASH Diet Plan to Reduce Blood Pressure
The Dietary Approaches to Stop Hypertension (DASH) diet is clinically proven to lower blood pressure within two weeks:
- Slash Sodium Intake: Limit table salt to less than 1 teaspoon (2,300 mg sodium) daily; avoid processed pickles, papads, and namkeens.
- Boost Potassium-Rich Foods: Bananas, coconut water, spinach, and sweet potatoes help balance sodium levels in vascular smooth muscle.
- Include Magnesium and Calcium: Almonds, flaxseeds, low-fat curd, and legumes improve arterial elasticity.
