At Unihealth Southwoods Hospital’s Heart Station, we often see firsthand how high blood pressure, or hypertension, can quietly sneak up on people without any obvious symptoms.
But don’t be fooled.
It’s a silent threat that can lead to serious health problems like heart disease, stroke, and kidney failure if left unchecked.
That’s why understanding the early signs and acting fast is crucial.
That’s why understanding the early signs and acting fast is crucial. At Unihealth Southwoods Hospital, we’re committed to helping you detect, manage, and treat high blood pressure before it becomes a life-altering issue.
Let’s break down the top five reasons why you should never ignore high blood pressure symptoms and how expert care can make all the difference.
What Is High Blood Pressure?
High blood pressure (also called hypertension) is when the force of blood against your artery walls is consistently too high. If left unmanaged, it can silently cause severe health problems like stroke, kidney failure, or heart disease.
Filipinos with hypertension are growing in numbers in adults, with many unaware they have it until complications arise.
Why High Blood Pressure Is Called the “Silent Killer”?
One of the most dangerous things about high blood pressure is that it often presents no noticeable symptoms. That’s why it’s commonly referred to as the silent killer.
Although, hypertensive diseases are still one of the leading causes of death in the Philippines, according to the Philippine Statistics Authority. Many Filipinos only discover they have high blood pressure after experiencing a life-threatening event.
Reason 1: Increased Risk of Heart Disease
The Heart Works Harder
When your blood pressure is high, your heart has to pump with more force to move blood through your body. Over time, this causes your heart muscle to thicken.
How High Blood Pressure Damages the Heart
When arteries harden or narrow due to hypertension, blood flow is reduced, and eventually, the overworked heart can’t keep up, increasing your risk of:
- Coronary artery disease
- Heart attack
- Irregular heartbeat
- Heart failure
Pro Tip: Regular heart check-ups at USHMC can detect early signs of cardiac damage.
Reason 2: Stroke and Brain Damage

How Hypertension Affects the Brain
High blood pressure weakens or damages the blood vessels in your brain. If a vessel bursts or gets blocked, it can lead to a stroke.
Link Between Hypertension and Stroke
Elevated blood pressure can cause:
- Blood vessels in the brain to burst (hemorrhagic stroke)
- Blood clots that block brain flow (ischemic stroke)
Even temporary spikes in blood pressure can lead to transient ischemic attacks (TIAs) or mini-strokes.
Reason 3: Kidney Failure and Organ Damage
Understanding the BP-Kidney Connection
Your kidneys filter waste from your blood, and they rely on healthy blood vessels to do their job. High blood pressure can damage these vessels.
How Blood Pressure Affects the Kidneys
Common signs of kidney stress include:
- Swelling in ankles or feet
- Shortness of breath
- Changes frequency, appearance, and volume in urination
Without early treatment, chronic kidney disease (CKD) or complete renal failure can occur.
Reason 4: Vision Problems and Blindness
High BP Can Ruin Your Retina
The retina in your eye needs steady, gentle blood flow. Hypertension causes the blood vessels in your eyes to swell or bleed, a condition known as hypertensive retinopathy.
Hypertensive Retinopathy
This condition leads to:
- Blurry vision
- Eye pain
- Complete vision loss in severe cases
An eye check-up can reveal blood vessel damage long before symptoms appear.
Reason 5: Delayed Treatment Can Be Fatal
Many people dismiss fatigue or dizziness, not realizing these are red flags. Without timely intervention, high blood pressure can cause irreversible damage or even death.
Why Early Diagnosis Saves Lives
Timely treatment includes:
- Lifestyle changes
- Medication management
- Regular monitoring
Common Symptoms You Shouldn’t Ignore
While often asymptomatic, here are warning signs to watch out for:
- Persistent headaches
- Dizziness
- Chest pain
- Blurred vision
- Fatigue
- Nosebleeds
If you notice these, get your BP checked immediately at a nearby clinic like Unihealth Southwoods Hospital. A simple BP reading takes less than 5 minutes. But it can add years to your life if done regularly.
Diagnosing High Blood Pressure in the Philippines
Here’s how high blood pressure is diagnosed:
Blood Pressure Level | Systolic | Diastolic |
Normal | <120 | <80 |
Elevated | 120–129 | <80 |
High (Stage 1) | 130–139 | 80–89 |
High (Stage 2) | ≥140 | ≥90 |
Visit your local health center or Unihealth Southwoods for accurate blood pressure checkup.
Who’s at Risk for High Blood Pressure?
Risk Factors You Can and Can’t Control
- Uncontrollable: Age, genetics, family history
- Controllable: Diet, activity level, smoking, alcohol, stress
Filipinos and Lifestyle-Related Risks
With more processed foods, sedentary jobs, and stress-heavy lives, many Filipinos have health problems and are walking around with undiagnosed high blood pressure.
How to Manage and Prevent Hypertension

Lifestyle Changes That Work
- Eat more fruits and vegetables
- Reduce salt and fatty food intake
- Get regular exercise
- Stop smoking and limit alcohol
- Manage stress through rest and hobbies
Medication and Medical Support Sometimes lifestyle changes aren’t enough. Don’t be afraid to rely on prescribed medication to keep your numbers stable.
Why Early Diagnosis is Key
The Power of Preventive Care
Catching high blood pressure early means avoiding strokes, kidney failure, and heart attacks. It also means less expensive treatments and better quality of life.
