"Understanding the Causes of Hypertension"

Hypertension, commonly known as high blood pressure, is a serious medical condition that affects millions of people worldwide. It is an insidious ailment because it often presents with no obvious symptoms yet can lead to severe health complications like heart disease, stroke, and kidney failure if left unmanaged. This article seeks to shed light on the potential causes of hypertension, raising awareness about this silent killer and its risks. Before pinpointing the causes, it is crucial to understand what hypertension signifies.

What Is Hypertension?

In medical parlance, hypertension refers to a condition characterized by persistently elevated arterial blood pressure. Blood pressure is measured in millimeters of mercury (mmHg) and is presented as two values: systolic over diastolic. Systolic pressure, the higher value, indicates the force exerted on artery walls when the heart beats. Meanwhile, diastolic pressure, the lower figure, symbolizes the pressure in your arteries when your heart rests between beats.

Generally, normal blood pressure should be around 120/80mmHg. If the blood pressure regularly sails over 140/90mmHg, it is diagnosed as hypertension.

Primary (Essential) Hypertension

In most cases, the exact cause of hypertension is not identifiable, prompting the reference as primary or essential hypertension. This form of hypertension is by far the most widespread, accounting for about 90-95% of cases. It is believed that this hypertension type arises from a complex interaction of genetics and environmental factors. Age and family history are vital factors, as the likelihood of developing hypertension magnifies as you age or if high blood pressure is typical in your family.

Environmental influences also play a crucial part. Diet, specifically those high in sodium and low in potassium, can contribute to hypertension development. Lack of physical activity, obesity, tobacco use, and alcohol consumption are other significant risk factors.

Secondary Hypertension

On the other hand, about 5-10% of hypertension cases are secondary hypertension. In contrast to primary hypertension, secondary hypertension springs from a recognizable underlying health issue. Chronic kidney disease, hormonal disorders, certain medications such as birth control pills and over-the-counter pain relievers, and excessive alcohol or illicit drug use can instigate secondary hypertension.

Hypertension Risks

Uncontrolled hypertension can cause damage to your body for years before symptoms become noticeable, leading to severe health complications. Hypertension can damage blood vessels and your heart, leading to heart attacks or strokes. It can also cause kidney diseases and heart failure.

Managing Hypertension

Managing hypertension primarily involves lifestyle changes, such as adopting healthy dietary habits and regular exercise. In some cases, medication may be necessary. It’s important to have regular check-ups to manage hypertension effectively and lower the risks of complications.


In conclusion, while the exact causes of hypertension may vary, there are common factors associated with the condition, such as advanced age, family history, dietary habits, lack of physical activity, and other health conditions. Awareness of these factors is fundamental in mitigating the risks and managing the condition.


  1. Can hypertension be cured permanently?

    No, but it can be managed effectively through lifestyle changes and medication when necessary.

  2. At what blood pressure level should I be concerned?

    Blood pressure over 140/90mmHg on regular readings is generally deemed as hypertension and warrants medical attention.

  3. What dietary changes can help manage hypertension?

    Lowering salt intake, increasing consumption of fruits and vegetables, moderating alcohol consumption, and maintaining a healthy weight can help manage hypertension.

  4. Can stress cause hypertension?

    While stress isn’t directly linked to chronic hypertension, it can lead to behaviors that increase the risk of hypertension like unhealthy diet and excessive alcohol consumption.

  5. Do I need medication for hypertension?

    It depends on the severity of your hypertension. In some cases, lifestyle changes might be enough, but in others, medication might be required. Always consult your healthcare provider.
