High Blood Pressure (Hypertension) Explained

High Blood Pressure (Hypertension) Explained

What is High Blood Pressure (Hypertension)?

High blood pressure, also known as hypertension, occurs when the force of blood against the walls of your arteries is consistently too high. Over time, this condition can lead to serious health problems such as heart disease, stroke, and kidney failure. Blood pressure is measured in millimeters of mercury (mmHg) and consists of two numbers: systolic (pressure when your heart beats) and diastolic (pressure when your heart rests between beats).

Classifying High Blood Pressure (Hypertension)

Hypertension is classified as a chronic condition that requires long-term management. It can be categorized into two main types:

1. Primary (Essential) Hypertension: This type has no identifiable cause and tends to develop gradually over years.
2. Secondary Hypertension: This type is caused by an underlying condition, such as kidney disease, hormonal disorders, or medication use, and it tends to appear suddenly.

Types of High Blood Pressure (Hypertension)

1. Primary (Essential) Hypertension: The most common type with no specific cause.
2. Secondary Hypertension: Caused by underlying health conditions like kidney disease, sleep apnea, or hormonal imbalances.
3. Resistant Hypertension: High blood pressure that remains elevated despite treatment with three or more medications.
4. Hypertensive Crisis: A severe, sudden spike in blood pressure that requires immediate medical attention.

High Blood Pressure (Hypertension) Health Signs and Symptoms

Hypertension is often called the “silent killer” because it can develop without obvious symptoms. However, in severe cases, you may experience:

• Headaches
• Shortness of breath
• Nosebleeds
• Blurred vision
• Dizziness
• Chest pain
• Fatigue

High Blood Pressure (Hypertension) Causes

• Genetics: Family history of hypertension increases risk.
• Age: Blood pressure tends to increase with age.
• Obesity: Excess weight forces the heart to work harder.
• Sedentary lifestyle: Lack of physical activity can raise blood pressure.
• Diet: High salt intake, low potassium levels, and excessive alcohol consumption contribute to hypertension.
• Stress: Long-term stress can lead to chronic high blood pressure.
• Underlying conditions: Kidney disease, sleep apnea, and thyroid problems can cause secondary hypertension.

High Blood Pressure (Hypertension) Stages

1. Elevated Blood Pressure: 120-129 systolic and less than 80 diastolic.
2. Stage 1 Hypertension: 130-139 systolic or 80-89 diastolic.
3. Stage 2 Hypertension: 140 or higher systolic or 90 or higher diastolic.
4. Hypertensive Crisis: Above 180 systolic or 120 diastolic (requires emergency care).

How to Prevent High Blood Pressure (Hypertension)?

• Maintain a healthy weight: Obesity is a major risk factor.
• Exercise regularly: Aim for at least 150 minutes of moderate-intensity exercise per week.
• Eat a heart-healthy diet: Include fruits, vegetables, whole grains, and low-fat dairy products.
• Reduce salt intake: Limit sodium to less than 2,300 mg per day, or even lower.
• Limit alcohol: Drink in moderation, if at all.
• Quit smoking: Smoking damages blood vessels and raises blood pressure.
• Manage stress: Relaxation techniques like meditation and deep breathing can help.

High Blood Pressure (Hypertension) Diagnosis

• Blood Pressure Reading: Your doctor will use a sphygmomanometer to measure your blood pressure in a clinical setting.
• Ambulatory Blood Pressure Monitoring: A portable device measures your blood pressure over 24 hours to assess fluctuations.
• Blood Tests: These can help identify secondary causes of hypertension, such as kidney or thyroid problems.
• Electrocardiogram (ECG): Assesses the electrical activity of the heart and checks for any strain caused by high blood pressure.

How to Test for High Blood Pressure (Hypertension)?

• Blood Pressure Cuff (Sphygmomanometer): The most common test in a doctor’s office or home setting.
• Ambulatory Monitoring: Tracks blood pressure over a full day to detect hypertension that may not show up in the doctor’s office.
• Blood Tests: To rule out secondary hypertension caused by other health conditions.
• Urinalysis: Checks for kidney problems that may be linked to high blood pressure.

What Type of Health Professionals Treat High Blood Pressure (Hypertension)?

• Primary Care Physicians: Often the first to diagnose and treat hypertension.
• Cardiologists: Specialists in heart health who manage complex hypertension cases.
• Nephrologists: Treat high blood pressure linked to kidney disease.
• Endocrinologists: Specialize in hormonal conditions that may cause secondary hypertension.

Reasons to See a High Blood Pressure (Hypertension) Health Professional

• If you have consistently high readings over 130/80 mmHg.
• When lifestyle changes are not enough to control blood pressure.
• If you have symptoms like chest pain, dizziness, or shortness of breath.
• When diagnosed with an underlying condition like kidney disease or diabetes that can worsen hypertension.

Process to Find the Right Specialist for High Blood Pressure (Hypertension)

• Referrals: Ask your primary care provider for a referral to a cardiologist or nephrologist if necessary.
• Research: Look for specialists with experience managing hypertension, particularly resistant hypertension or secondary causes.
• Insurance: Check with your insurance provider to ensure your specialist visits are covered.

How to Prepare to See a Health Specialist?

• Symptom log: Keep track of your blood pressure readings and any symptoms like headaches or chest pain.
• Medical history: Note any family history of hypertension or related conditions.
• Lifestyle details: Be prepared to discuss your diet, exercise, and stress levels.
