Introduction
He felt fine. That was the problem.
For years, Mallam Usman, a trader in his early fifties from Gombe, had no symptoms. No headaches. No dizziness. No warning signs. Then one afternoon, he collapsed at his shop. The diagnosis at the hospital was a stroke caused by severely uncontrolled high blood pressure a condition he did not know he had.
Stories like this play out across Nigeria every single day. High blood pressure, medically known as hypertension, is one of the most common and most dangerous chronic diseases in the country. What makes it especially deadly is that it almost never causes symptoms. You can have dangerously high blood pressure for years without feeling a single warning sign until the day it causes a heart attack, stroke, or kidney failure.
This guide explains what high blood pressure is, who is at risk, how to know if you have it, and most importantly how to control it before it causes serious damage.
What is High Blood Pressure?
Blood pressure is the force that your blood exerts against the walls of your arteries as your heart pumps it around your body.
It is measured using two numbers:
Systolic pressure – the pressure when your heart beats
Diastolic pressure – the pressure when the heart relaxes between beats
A normal blood pressure reading is roughly 120/80 mmHg.
In Nigeria and most international guidelines, hypertension is diagnosed when blood pressure is consistently 140/90 mmHg or higher on repeated measurements. Some newer guidelines in the United States use a lower threshold (130/80 mmHg), but the 140/90 definition remains the standard used in many countries and clinical settings.
When blood pressure stays elevated over time, it places continuous strain on the heart, blood vessels, brain, kidneys, and eyes.
How Common is Hypertension in Nigeria?
The statistics are alarming.
Studies estimate that around 30% of Nigerian adults have hypertension, meaning roughly one in every three adults may have high blood pressure.
Even more concerning is how few people know they have it.
Research shows that in Nigeria:
Only about 29% of people with hypertension know they have the condition
Only around 12% are receiving treatment
Only about 2–3% have their blood pressure adequately controlled
This means millions of Nigerians are living with uncontrolled hypertension without realizing it.
Why is it Called the Silent Killer?
High blood pressure is often called the silent killer because it can cause serious internal damage for many years without producing symptoms.
The elevated pressure gradually damages:
The heart
The heart must pump harder against increased pressure, which can lead to heart enlargement and eventually heart failure.
The arteries
Blood vessels become stiff and narrowed, increasing the risk of heart attack and stroke.
The brain
A blocked or ruptured blood vessel can cause stroke, which may result in death or permanent disability.
The kidneys
Hypertension damages the delicate filtering units of the kidneys, leading to kidney failure.
The eyes
Damage to retinal blood vessels can cause progressive vision loss.
The most dangerous fact is this:
Many people with dangerously high blood pressure feel completely normal.
Symptoms often do not appear until serious damage has already occurred.
Who is at Risk?
Anyone can develop high blood pressure, but the risk increases with certain factors:
Age (risk rises after age 40)
Family history of hypertension
Diet high in salt
Overweight or obesity
Physical inactivity
Smoking
Excess alcohol consumption
Chronic stress
Diabetes
Kidney disease
Some lifestyle and dietary patterns common in many Nigerian communities, including high sodium intake and reduced physical activity, may increase risk.
Symptoms — Usually There Are None
One of the biggest misconceptions about hypertension is that people expect to feel sick when blood pressure is high.
In reality, most people experience no symptoms at all, even when blood pressure is dangerously elevated.
Occasionally, extremely high blood pressure may cause:
Severe headaches
Blurred vision
Nosebleeds
Shortness of breath
Chest pain
Dizziness
However, even among patients with very high blood pressure, these symptoms occur in only a minority of cases.
The only reliable way to know your blood pressure is to measure it.
How is High Blood Pressure Diagnosed?
Diagnosis is simple and painless.
A blood pressure cuff is placed around your upper arm and the pressure is measured as the cuff inflates and deflates.
To ensure accuracy, proper measurement technique is important:
Sit quietly for at least five minutes before measurement
Keep your feet flat on the floor
Rest your arm at heart level
Avoid talking during the measurement
Use a correctly sized cuff
Because blood pressure fluctuates naturally, doctors usually confirm hypertension after multiple readings taken on different days.
At Amkamed Pharmaceuticals in Gombe State, we offer blood pressure checks and encourage every adult over 30 to know their numbers.
How is High Blood Pressure Treated?
Lifestyle Changes The Foundation of Treatment
Healthy lifestyle habits can significantly reduce blood pressure:
Reduce salt intake (ideally less than 5 grams per day)
Exercise regularly (at least 30 minutes most days)
Maintain a healthy body weight
Stop smoking
Limit alcohol consumption
Manage stress
Eat more fruits, vegetables, and whole grains
The DASH diet has strong scientific evidence showing significant reductions in blood pressure.
Medication Often Necessary
For many patients, lifestyle changes alone are not enough.
Doctors commonly prescribe medications such as:
ACE inhibitors (e.g., lisinopril, enalapril)
Relax blood vessels.
Calcium channel blockers (e.g., amlodipine)
Widen arteries and improve blood flow.
Diuretics (e.g., hydrochlorothiazide)
Help the body remove excess salt and water.
Beta blockers (e.g., atenolol)
Reduce heart rate and the force of contraction.
Many patients require two or more medications to achieve good blood pressure control.
The Most Dangerous Mistake: Stopping Medication
One of the most common and dangerous mistakes hypertension patients make is stopping medication when they start feeling better.
Hypertension is a lifelong condition.
Medication keeps blood pressure controlled. If you stop taking it, your blood pressure usually rises again often quickly.
Never stop or change your medication without consulting a doctor or pharmacist.
At Amkamed Pharmaceuticals, our pharmacists are always available to help patients understand and manage their blood pressure medications safely.
Conclusion
High blood pressure is one of the most common causes of stroke, heart disease, and kidney failure in Nigeria.
It usually causes no symptoms, which is why so many people do not know they have it.
The good news is that hypertension can be successfully controlled with early detection, proper medication, and healthy lifestyle choices.
