You feel fine. You go to work, spend time with your family and carry on with everyday life. Yet, inside your body, your blood pressure could be dangerously high without giving you an obvious warning.
That is one reason high blood pressure in Nigeria deserves far more attention.
Also known as hypertension, high blood pressure is sometimes called a “silent killer” because many people living with it have no noticeable symptoms. However, if it remains uncontrolled, it can gradually damage blood vessels and vital organs, increasing the risk of serious health problems such as stroke, heart disease and kidney disease.
The scale of the problem in Nigeria is significant. According to the World Health Organization’s 2025 hypertension country profile, an estimated 22 million Nigerian adults aged 30–79 were living with hypertension in 2024. Yet only about 13% had their blood pressure under control.
That means knowing your blood pressure numbers could be one of the simplest but most important things you do for your health.
As the world marks World Patient Safety Day on September 17, 2026, under the theme “Safe care for noncommunicable diseases” and the slogan “Safe care for life!”, St. Ives Specialist Hospital is encouraging individuals and families to make regular blood pressure checks part of routine healthcare.
What Is High Blood Pressure?
Blood pressure measures the force of blood pushing against the walls of your arteries as your heart pumps blood around your body.
It is recorded using two numbers. For example:
120/80 mmHg
The top number, called systolic blood pressure, measures the pressure when your heart contracts and pumps blood.
Meanwhile, the bottom number, called diastolic blood pressure, measures the pressure when your heart relaxes between beats.
According to the World Health Organization, hypertension is generally diagnosed when blood pressure readings taken on different days show a systolic pressure of 140 mmHg or higher and/or a diastolic pressure of 90 mmHg or higher.
However, blood pressure assessment is not simply about one number. Your doctor may consider repeated readings, your medical history, age, pregnancy status, other health conditions and your overall cardiovascular risk.
Therefore, one unusually high reading does not always mean you have hypertension. Persistent high readings, however, should never be ignored.
High Blood Pressure in Nigeria: Why Should We Be Concerned?
Hypertension is not a problem that affects only older adults.
Young adults, middle-aged people, older people and pregnant women can all develop high blood pressure. Moreover, factors such as family history, diet, excess body weight, physical inactivity and other medical conditions can increase a person’s risk.
The latest WHO estimates highlight the challenge facing Nigeria.
Among Nigerian adults aged 30–79 with hypertension:
- Approximately 50% have been diagnosed.
- Only about 32% are receiving treatment.
- Just 13% have their hypertension controlled.
- Approximately 19.1 million adults with hypertension do not have the condition controlled.
These figures make routine screening particularly important. After all, you cannot manage a blood pressure problem you do not know you have.
What Are the Symptoms of High Blood Pressure?
Here is something everyone should understand:
High blood pressure often causes no symptoms at all.
You can look healthy, feel energetic and still have hypertension.
This is why waiting for hypertension symptoms before checking your blood pressure can be dangerous.
When blood pressure becomes extremely high, however, some people may experience warning symptoms such as:
- Severe headache
- Chest pain
- Shortness of breath
- Changes in vision
- Weakness or numbness
- Difficulty speaking
- Dizziness or confusion
Importantly, these symptoms should not be used to diagnose hypertension yourself. A proper blood pressure measurement and medical assessment are essential.
Can You Have Hypertension Without Symptoms?
Yes. Absolutely.
In fact, many people with hypertension do not know they have it until their blood pressure is measured during a routine health check or after a complication develops.
Therefore, “I feel fine” should never replace “I know my blood pressure.”
Regular screening remains one of the most effective ways to detect high blood pressure early.
What Causes High Blood Pressure?
For many people, there is no single identifiable cause. Instead, hypertension can develop gradually as several risk factors interact over time.
Common causes of high blood pressure and contributing risk factors include:
- A family history of hypertension
- Increasing age
- Eating too much salt or sodium
- Being overweight or living with obesity
- Physical inactivity
- Tobacco use
- Excessive alcohol consumption
- Long-term stress and poor sleep
- Diabetes
- Kidney disease
- Certain medications
- Some hormonal or endocrine disorders
Genetics also matters. Therefore, having parents or close relatives with hypertension may increase your risk even when you currently feel healthy.
Rather than assuming you are safe because of your age or appearance, discuss your individual risk factors with a healthcare professional.
Does Nigerian Food Cause High Blood Pressure?
There is no single “Nigerian food” that automatically causes hypertension.
However, how food is prepared and how frequently certain foods are eaten can matter.
For example, a diet containing too much salt or sodium can contribute to raised blood pressure. Sodium may come not only from table salt but also from highly processed foods, packaged snacks, some seasonings, sauces and other sodium-rich products.
The answer is not to fear Nigerian food.
Instead, aim for balance.
Include more vegetables, fruits, whole grains and other minimally processed foods. In addition, pay attention to portion sizes, sodium intake and how frequently you consume heavily processed or salty meals.
Healthy eating should be practical enough to become a lifestyle, not a punishment you abandon after one week.
Stress and High Blood Pressure: Is There a Connection?
“Is it stress?” is a common question when someone’s blood pressure suddenly rises.
Stress can temporarily increase blood pressure. Furthermore, chronic stress may encourage behaviours that affect cardiovascular health, such as poor sleep, unhealthy eating, physical inactivity or excessive alcohol use.
However, repeatedly blaming high readings on stress can delay proper diagnosis.
If your blood pressure remains elevated, get evaluated by a healthcare professional rather than assuming work pressure, Lagos traffic or a stressful week is the only explanation.
What Blood Pressure Is Considered Dangerous?
A severely elevated blood pressure reading requires attention.
For non-pregnant adults, a reading higher than 180/120 mmHg can indicate severe hypertension.
If you get such a reading, sit calmly and repeat the measurement after at least one minute. If it remains extremely high, seek prompt medical advice.
More importantly, if a blood pressure above 180/120 mmHg occurs together with symptoms such as chest pain, shortness of breath, weakness, numbness, vision changes or difficulty speaking, it may represent a hypertensive emergency.
Seek emergency medical care immediately.
Do not wait for the symptoms to disappear on their own.
Why Untreated Hypertension Can Be Dangerous
Imagine water travelling through a pipe under excessive pressure day after day.
Eventually, the pipe can become damaged.
Something similar can happen inside the body when blood pressure remains uncontrolled for years. Persistent hypertension puts extra strain on blood vessels and organs.
Over time, uncontrolled hypertension can increase the risk of:
- Stroke
- Heart attack
- Heart failure
- Kidney disease
- Damage to the eyes
- Blood vessel damage
- Cognitive and other cardiovascular complications
This is why hypertension treatment is not simply about getting a “good number” on a blood pressure monitor. The bigger goal is protecting your heart, brain, kidneys and long-term quality of life.
Hypertension in Pregnancy: What Every Woman Should Know
High blood pressure deserves special attention before, during and after pregnancy.
Hypertension in pregnancy may already exist before conception, develop during pregnancy or occur as part of a serious pregnancy complication such as preeclampsia.
A blood pressure reading of 140/90 mmHg or higher during pregnancy is concerning and requires medical assessment. Severe hypertension during pregnancy is generally considered 160/110 mmHg or higher.
Pregnant women should seek medical attention for warning signs such as:
- A severe or persistent headache
- Changes in vision
- Pain in the upper abdomen
- Sudden swelling of the face or hands
- Difficulty breathing
- Sudden or concerning symptoms during the second half of pregnancy
Preeclampsia can sometimes develop without obvious symptoms. Therefore, regular antenatal appointments, blood pressure monitoring and appropriate laboratory checks are extremely important.
If you already have hypertension and are planning a pregnancy, speak with your doctor beforehand. Some blood pressure medicines may need to be reviewed because treatment during pregnancy requires careful medical supervision.
Can High Blood Pressure Be Treated?
Yes. Hypertension can be effectively managed.
Treatment depends on how high your blood pressure is, your overall cardiovascular risk and whether you have other conditions such as diabetes, kidney disease or heart disease.
A personalised hypertension treatment in Nigeria may involve lifestyle changes, medication or both.
Your doctor may recommend changes such as:
- Reducing excessive salt intake
- Eating a balanced, heart-friendly diet
- Exercising regularly as medically appropriate
- Maintaining a healthy body weight
- Avoiding tobacco
- Limiting alcohol
- Getting adequate sleep
- Managing stress
- Taking prescribed medication consistently
Most importantly, do not stop blood pressure medication because your numbers have improved.
A lower reading may actually mean the treatment is working.
Stopping medication suddenly or changing your dose without medical guidance can put your health at risk.
How to Check Your Blood Pressure Correctly
Getting an accurate reading matters.
Before checking your blood pressure, sit quietly for a few minutes. Keep your back supported, your feet flat on the floor and your arm supported around heart level.
Avoid talking during the measurement.
If you monitor your blood pressure at home, keep a record of your readings. This can help your doctor identify patterns and determine whether your treatment plan is working.
However, home monitoring should complement professional medical care rather than replace it.
If you are looking for a blood pressure check in Lagos, a routine health assessment can provide an opportunity to check not only your blood pressure but also other important cardiovascular risk factors where clinically appropriate.
When Should You See a Doctor About High Blood Pressure?
Do not wait until hypertension makes you feel ill.
Consider seeing a doctor if:
- Your blood pressure is repeatedly high.
- You have a family history of hypertension, stroke or heart disease.
- You have diabetes, kidney disease or another chronic condition.
- You are overweight or have other cardiovascular risk factors.
- You are pregnant and record an elevated blood pressure.
- You already take hypertension medication but your readings remain high.
- You have not had your blood pressure checked recently.
Meanwhile, extremely high blood pressure accompanied by chest pain, breathing difficulty, weakness, vision problems or difficulty speaking requires urgent emergency medical attention.
Early assessment gives your healthcare team the opportunity to identify risks, investigate possible causes and begin appropriate management before complications develop.
World Patient Safety Day 2026: Safe Care for Life
World Patient Safety Day is observed every year on September 17.
For 2026, the World Health Organization is focusing on “Safe care for noncommunicable diseases”, under the slogan “Safe care for life!”
The campaign is especially relevant to conditions such as cardiovascular disease, diabetes, cancer and chronic respiratory disease because people living with noncommunicable diseases often need care over many years.
Safe care does not end with making a diagnosis.
It also means accurate monitoring, appropriate medication, regular follow-up, clear communication between patients and healthcare professionals, and helping people understand their own health.
Hypertension is a perfect example.
Knowing your blood pressure is the beginning. Keeping it safely controlled is the long-term goal.
Your Next Blood Pressure Check Could Be More Important Than You Think
You do not need to wait for a headache.
You do not need to wait until you feel dizzy.
And you certainly should not wait for an emergency.
A simple blood pressure check takes only a few minutes, yet the information it provides could help protect your heart, brain, kidneys and future health.

Frequently Asked Questions About High Blood Pressure
Most people with high blood pressure experience no early symptoms. This is why hypertension is often described as a silent condition. The safest way to know your blood pressure is to have it measured.
Yes. You can have hypertension for years without feeling unwell. Regular blood pressure checks are therefore important, particularly if you have risk factors such as a family history of hypertension, diabetes, excess weight or kidney disease.
For non-pregnant adults, blood pressure above 180/120 mmHg is severely elevated. Repeat the measurement after at least one minute. If it remains that high, contact a healthcare professional promptly. If it occurs with chest pain, difficulty breathing, weakness, numbness, vision changes or difficulty speaking, seek emergency medical attention immediately.
Yes. High blood pressure during pregnancy can affect both mother and baby and may be associated with conditions such as preeclampsia. A reading of 140/90 mmHg or higher during pregnancy requires medical assessment, while 160/110 mmHg or higher is considered severe hypertension.
Yes. Hypertension is not limited to older adults. Young adults can also develop high blood pressure, especially when risk factors such as family history, excess weight, high sodium intake, inactivity, kidney disease or other medical conditions are present.
For many people, hypertension is a long-term condition that needs ongoing management rather than a one-time cure. Healthy lifestyle changes and prescribed medication can often control blood pressure effectively and substantially reduce the risk of complications.
The ideal frequency depends on your age, current blood pressure, medical history and risk factors. People already diagnosed with hypertension may need more frequent monitoring. Ask your doctor how often you should check yours.
