High Blood Pressure Causes

High blood pressure, also known as hypertension, is a condition in which the force of the blood against the walls of the arteries is consistently too high. It’s often referred to as the “silent killer” because it may not cause noticeable symptoms for years while gradually damaging the heart, blood vessels, and other organs. Here are some common causes and symptoms of high blood pressure:


  1. Age: The risk of high blood pressure increases with age.
  2. Family History: A family history of hypertension can increase the likelihood of developing the condition.
  3. Race/Ethnicity: Some ethnic groups, such as African Americans, are more prone to developing high blood pressure.
  4. Gender: Men are generally more likely to develop high blood pressure than women, but the risk for women increases after menopause.
  5. Lifestyle Factors:
    • Unhealthy Diet: High sodium intake, low potassium intake, and a diet high in saturated fats can contribute.
    • Physical Inactivity: Lack of regular exercise is a risk factor.
    • Obesity: Being overweight or obese increases the risk of hypertension.
    • Excessive Alcohol Consumption: Drinking too much alcohol can raise blood pressure.
    • Smoking: Tobacco smoke can damage blood vessels and raise blood pressure.
  6. Chronic Kidney Disease: Kidney problems can lead to hypertension.
  7. Sleep Apnea: Untreated sleep apnea can contribute to high blood pressure.
  8. Certain Chronic Conditions: Conditions such as diabetes and high cholesterol can contribute to hypertension.
  9. Hormonal Factors: Hormonal changes, such as those related to pregnancy or hormonal contraceptives, can influence blood pressure.


Hypertension is often asymptomatic, meaning people may not experience noticeable symptoms. However, extremely high blood pressure levels may lead to:

  1. Headaches: Severe headaches, especially in the morning.
  2. Fatigue or Confusion: Feeling tired or confused.
  3. Vision Problems: Blurred or double vision.
  4. Chest Pain: Chest pain may occur in extreme cases.
  5. Irregular Heartbeat: Palpitations or a feeling of a fluttering heart.
  6. Difficulty Breathing: Shortness of breath.

It’s crucial to note that these symptoms are not specific to high blood pressure and can be associated with other health issues. The only way to diagnose hypertension is through regular blood pressure monitoring.

If you suspect you have high blood pressure or have risk factors, it’s important to consult with a healthcare professional. Lifestyle changes, medications, or a combination of both may be recommended to manage blood pressure and reduce the risk of complications. Regular check-ups are essential for monitoring and managing hypertension effectively.

The high blood pressure explained

Blood pressure is a measure of the force of blood against the walls of your arteries as your heart pumps it around your body. It is expressed as two numbers: systolic pressure over diastolic pressure, measured in millimeters of mercury (mmHg). The normal range for blood pressure is typically considered to be around 120/80 mmHg.

Blood pressure levels can be categorized as follows:

  1. Normal: Systolic < 120 mmHg and diastolic < 80 mmHg
  2. Elevated: Systolic 120-129 mmHg and diastolic < 80 mmHg
  3. Hypertension Stage 1: Systolic 130-139 mmHg or diastolic 80-89 mmHg
  4. Hypertension Stage 2: Systolic ≥140 mmHg or diastolic ≥90 mmHg
  5. Hypertensive Crisis: Systolic >180 mmHg and/or diastolic >120 mmHg

Persistently high blood pressure, especially in the hypertensive range, can lead to serious health problems. It increases the risk of heart disease, stroke, and other cardiovascular diseases. Additionally, it can damage organs such as the kidneys and eyes over time.

Low blood pressure (hypotension) can also be a concern, as it may result in inadequate blood flow to vital organs, leading to dizziness, fainting, and other symptoms.

It’s important to note that blood pressure can fluctuate throughout the day, and a single elevated reading does not necessarily mean you have hypertension. Diagnosis is typically based on multiple readings over time.

If you are concerned about your blood pressure, it’s advisable to consult with a healthcare professional. They can provide guidance on lifestyle changes, medications, or other interventions to help manage blood pressure and reduce associated health risks. Regular monitoring and check-ups are essential for maintaining cardiovascular health.
