Signs of hypertension
Many people have high blood pressure but are unaware of their health condition. It will help to know some of the warning signs of hypertension so you can get early treatment.
High blood pressure is also called hypertension. Blood pressure is the force that blood exerts on a blood vessel as it flows through it. High blood pressure describes the condition in which the force of blood flowing through the blood vessels is always high.
High blood pressure is a dangerous condition that can affect the heart as it makes the heart work harder to pump blood to all parts of the body. It can also cause the hardening of arteries and can lead to stroke.
High blood pressure can be genetically inherited. Age and race can also play a role in its development. According to a study, older people are disproportionately affected by hypertension, and the majority of them die from non-communicable diseases like hypertension, diabetes and heart diseases.
The fact that hypertension cannot be seen nor felt most times makes it more dangerous. It is a silent killer. Your blood pressure could be high, and you won’t know. In fact, according to the CDC, about one in five adults with hypertension are unaware of their condition.
This article discusses what high blood pressure means, the blood pressure range chart, warning signs of high blood pressure and how to lower high blood pressure naturally.
Blood pressure range chart
Your blood pressure is considered normal if you have a systolic blood pressure of less than 120 and a diastolic blood pressure of less than 80 (120/80 mm Hg).
According to the American Heart Association, there are five blood pressure ranges:
- Normal blood pressure
- Elevated blood pressure
- Hypertension stage 1
- Hypertension stage 2
- Hypertensive crisis
Below is a blood pressure range chart. Learn what is considered normal, elevated or high blood pressure using the blood pressure range chart.
Blood Pressure Category
Systolic mm Hg (upper number)
Diastolic mm Hg (lower number)
Less than 120
Less than 80
Less than 80
High blood pressure stage 1
High blood pressure stage 2
140 or higher
90 or higher
Hypertensive crisis (needs urgent medical attention)
Higher than 180
Higher than 120

Warning signs of high blood pressure
While hypertension is prevalent among adults, younger people can develop the condition too. This is why it is vital that you constantly check your blood pressure level. Constant monitoring of your blood pressure will help prevent medical emergencies and make you live a more healthy life.
Below are some common warning signs of blood pressure to always watch out for.
One of the common warning signs of prolonged high blood pressure is sudden dizziness and loss of coordination or balance.
Dizziness is usually a sign of stroke in people with hypertension. A stroke occurs due to a loss of blood supply to the brain. Sometimes, hypertension medications also cause dizziness
2. Shortness of breath
People with pulmonary hypertension may feel out of breath and may experience difficulties carrying out their daily activities. Pulmonary hypertension is a type of hypertension that affects the arteries in the lungs and the heart.
Prolonged high blood pressure can cause shortness of breath and fatigue. However, sudden shortness of breath can also be a sign of other severe health complications like heart attack and stroke.
3. Facial flushing
Facial flushing happens when blood vessels on the face dilate. Causes of facial flushing include cold weather, sun exposure, taking hot drinks and spicy foods and some skin-care products.
Also, things that affect blood pressure such as alcohol consumption, emotional stress and exercise (which can raise blood pressure temporarily) can cause facial flushing. Note that facial flushing may occur with hypertension, but hypertension is not the cause of facial flushing.
5. Blood spots in the eyes

This is another warning sign of high blood pressure that must not be ignored. Blood spots occur as red spots in the eye. Such red spots are also called subconjunctival haemorrhages. A subconjunctival haemorrhage occurs when tiny blood vessels under the conjunctiva break, causing blood to be trapped.
In the case of hypertension, subconjunctival haemorrhage occurs when too much pressure on the tiny arterial walls stretches the arteries' tissues, causing them to damage and break. The arteries and optical nerves of the eyes might get damaged if left untreated.
High blood pressure can cause you to throw up. Vomiting is more common with hypertensive crises. A hypertensive crisis is an extremely high blood pressure that requires immediate medical attention. Other symptoms of a hypertensive crisis include bleeding from the nose, confusion and blurred vision.
One of the subtle warning signs of high blood pressure is anxiety. Anxiety is not normal. It is a disorder just like depression. Unfortunately, high blood pressure can also cause feelings of anxiety.
Severe anxiety causes symptoms of sweating, breathlessness, heavy breathing and trembling. If you are experiencing these symptoms, it will help to see a physician for a proper diagnosis. Anxiety itself can cause a spike in blood pressure levels; therefore, it needs to be treated.
Other warning signs of high blood pressure to look out for include fatigue, confusion, blood in urine and trouble sleeping.
How to lower high blood pressure naturally
Taking antihypertensive medication is one way to lower your blood pressure, but not everybody likes taking drugs all the time. There are ways to control or reduce blood pressure without taking medication, such as:
- Exercise regularly
- Reduce caffeine intake
- Manage or reduce stress
- Drink less alcohol
- Reduce sodium intake (don’t eat too much salt)
- Lose some weight
- Cut out added sugar and refined foods
- Quit smoking
- Practise deep breathing and yoga
- Get enough sleep
- Eat calcium-rich foods
- Eat natural supplements like garlic extract and whey protein
- Take zobo drinks to lower blood pressure
Note that these natural ways of reducing blood pressure don’t have to replace medications. They are only health management techniques.
If you have been diagnosed with hypertension, talk with your doctor first and know if it is okay to stay off medication. Whether you will take antihypertensive medicines will depend on your blood pressure range.
