Introduction
High blood pressure, also known as hypertension, is a common condition that affects millions of people worldwide. It is a major risk factor for heart disease, stroke, and other serious health issues. Understanding the causes, symptoms, and treatment options for hypertension is crucial for managing and preventing this condition.
What is High Blood Pressure?
High blood pressure occurs when the force of the blood against the artery walls is consistently too high. This condition is typically measured using two numbers: systolic and diastolic pressures. The systolic pressure (the top number) measures the pressure in your arteries when your heart beats, while the diastolic pressure (the bottom number) measures the pressure in your arteries when your heart is at rest between beats. A normal blood pressure reading is typically around 120/80 mm Hg.
Causes of High Blood Pressure
There are several factors that can contribute to the development of high blood pressure, including:
- Genetics: A family history of hypertension increases your risk.
- Age: Blood pressure tends to increase with age.
- Diet: High intake of salt, fat, and cholesterol can lead to hypertension.
- Lifestyle: Lack of physical activity, obesity, and excessive alcohol consumption are significant risk factors.
- Stress: Chronic stress can contribute to elevated blood pressure levels.
- Underlying Conditions: Conditions like diabetes and kidney disease can also cause hypertension.
Symptoms of High Blood Pressure
Hypertension is often called the "silent killer" because it typically has no symptoms until significant damage has been done. However, some people may experience:
- Headaches
- Dizziness
- Shortness of breath
- Nosebleeds
These symptoms are not specific to high blood pressure and usually occur when blood pressure has reached a dangerously high level.
Diagnosis of High Blood Pressure
High blood pressure is diagnosed through regular blood pressure readings. It is recommended to have your blood pressure checked at least once every two years if you are over 18, and more frequently if you have risk factors for hypertension. Blood pressure monitors are available at most pharmacies and can also be used at home for regular monitoring.

Medications for High Blood Pressure
There are several types of medications available to treat high blood pressure, including:
- Diuretics: Help the kidneys remove excess sodium and water.
- Beta-blockers: Reduce the workload on the heart and open blood vessels.
- ACE inhibitors: Relax blood vessels by blocking the formation of a natural chemical that narrows blood vessels.
- Calcium channel blockers: Help relax the muscles of your blood vessels.
Your doctor will work with you to determine the best medication or combination of medications for your specific condition.
Complications of Uncontrolled High Blood Pressure
If left untreated, high blood pressure can lead to serious health problems, including:
- Heart Disease: Increased risk of heart attacks and heart failure.
- Stroke: Hypertension is a major risk factor for stroke.
- Kidney Damage: High blood pressure can cause damage to the kidneys, leading to kidney failure.
- Vision Loss: Hypertension can damage the blood vessels in the eyes, leading to vision problems.
Preventing High Blood Pressure
Preventing high blood pressure involves adopting a healthy lifestyle, including:
- Healthy Diet: Eating plenty of fruits, vegetables, and whole grains.
- Regular Exercise: Engaging in at least 150 minutes of moderate exercise each week.
