Managing High Blood Pressure: A Complete Patient Guide

What Is High Blood Pressure?

Blood pressure is the force your blood exerts against your artery walls. A reading above 130/80 mmHg is now classified as high blood pressure (hypertension) by most international cardiology guidelines.

It is often called the “silent killer” because it produces no obvious symptoms — yet over time it dramatically increases the risk of:

• Heart attack and stroke
• Heart failure
• Chronic kidney disease
• Vision loss

Understanding Your Numbers

Category	Systolic		Diastolic
Normal	< 120	and	< 80
Elevated	120–129	and	< 80
High BP Stage 1	130–139	or	80–89
High BP Stage 2	≥ 140	or	≥ 90
Hypertensive Crisis	> 180	and/or	> 120

A single high reading is not a diagnosis. Your doctor will measure BP multiple times over several visits before confirming hypertension.

Lifestyle Changes That Work

1. Reduce Sodium Intake

Target under 2,300 mg of sodium per day (about one teaspoon of salt). Hidden sodium in processed foods, pickles, and papads is the biggest culprit in Indian diets. A low-sodium diet can reduce systolic BP by 5–6 mmHg.

2. The DASH Diet

The Dietary Approaches to Stop Hypertension (DASH) diet emphasises:

• Fruits, vegetables, and whole grains
• Low-fat dairy
• Lean poultry and fish
• Nuts, seeds, and legumes
• Minimal red meat, sweets, and sugary drinks

Studies show DASH can lower systolic BP by up to 11 mmHg — comparable to a single medication.

3. Regular Physical Activity

Aim for at least 150 minutes of moderate-intensity exercise per week — brisk walking, cycling, or swimming. Regular aerobic exercise reduces systolic BP by 5–8 mmHg.

4. Limit Alcohol

Even moderate alcohol raises BP. If you drink, limit to one standard drink per day for women and two for men.

5. Quit Smoking

Each cigarette causes a temporary spike in BP. Long-term smoking damages artery walls, accelerating hypertension and atherosclerosis.

6. Manage Stress

Chronic stress contributes to sustained BP elevation. Proven stress-management techniques include:

• Mindfulness meditation (even 10 minutes daily)
• Yoga and pranayama
• Adequate sleep (7–8 hours)

When Medication Is Needed

Lifestyle changes are the first line of treatment, but many patients also need medication. Our cardiologists follow evidence-based protocols to select the most appropriate agent for your specific profile:

• ACE inhibitors / ARBs — protect the kidneys, preferred in diabetics
• Calcium channel blockers — good first-line option for many patients
• Thiazide diuretics — particularly effective in South Asian populations
• Beta-blockers — used when heart rate or heart failure is also a concern

Never stop BP medication without consulting your doctor. Abrupt discontinuation can cause dangerous rebound hypertension.

Monitoring at Home

Home BP monitors are affordable and effective. Tips for accurate readings:

1. Sit quietly for 5 minutes before measuring
2. Use the same arm each time
3. Take two readings one minute apart and average them
4. Measure in the morning before medication and in the evening
5. Log readings in a diary or app to share with your doctor

When to Seek Emergency Care

Go to the nearest emergency department immediately if your reading exceeds 180/120 mmHg, especially with:

• Chest pain
• Severe headache or vision changes
• Shortness of breath
• Neurological symptoms (weakness, slurred speech)
