What Is Blood Pressure?

Blood pressure (BP) is the force of blood pushing against the walls of your arteries as your heart pumps blood around your body.

It is measured in millimeters of mercury (mmHg) and recorded as two numbers:

Example: 120/80 mmHg

• 120 = Systolic pressure (pressure when the heart beats)

• 80 = Diastolic pressure (pressure when the heart rests between beats)

Both numbers are important.

Is 120/80 Always Perfect?

Yes, 120/80 mmHg is considered ideal.

However, slight variations can still be normal depending on:

• Age

• Stress levels

• Physical activity

• Time of day

• Medication use

For example:

• 125/82 mmHg → Slightly elevated, needs monitoring

If your readings are consistently above 130/80 mmHg, you may be developing hypertension.

At this stage, you are at higher risk of:

If your reading reaches:

This is a hypertensive crisis and requires immediate medical attention.

Why Many Nigerians Don’t Know They Are Hypertensive

Hypertension is often called the “silent killer” because it usually has no obvious symptoms.

Here’s why many Nigerians don’t know:

1️⃣ No Regular Health Checkups

Many adults only visit hospitals when they feel seriously sick.

2️⃣ Lack of Home Monitoring

Few households own a digital blood pressure monitor.

3️⃣ Belief That “I Feel Fine”

High blood pressure can exist for years without pain.

4️⃣ Busy Lifestyle in Cities Like Lagos

Stress, traffic, and long working hours increase risk — but people ignore routine testing.

5️⃣ Poor Awareness

Some people believe headache must be present before BP is high. This is not true.

You can have 160/100 mmHg and still feel completely normal.
