Hypertension

Hypertension, or high blood pressure, is a condition in which the force of the blood against the artery walls is consistently too high. It’s often called the “silent killer” because it typically has no symptoms until significant damage has been done to the heart and arteries. Managing and preventing hypertension is crucial because it increases the risk of heart disease, stroke, kidney disease, and other health problems.

Types of Hypertension

1. Primary (Essential) Hypertension: The most common type, develops gradually over many years without a specific identifiable cause.
2. Secondary Hypertension: Caused by an underlying condition, such as kidney disease, hormonal disorders, certain medications, or sleep apnea. It tends to appear suddenly and causes higher blood pressure than primary hypertension.

Risk Factors

• Age: Risk increases with age.
• Genetics: Family history of hypertension.
• Lifestyle Factors: Lack of physical activity, poor diet (high in salt, fat, and cholesterol), smoking, and excessive alcohol consumption.
• Obesity: Excess weight increases the strain on the heart.
• Chronic Conditions: Such as diabetes, kidney disease, and sleep apnea.
• Stress: High levels of stress can contribute to transient increases in blood pressure.

Symptoms

Most people with hypertension have no symptoms, but in some cases, it can cause:

• Headaches
• Shortness of breath
• Nosebleeds

These symptoms usually occur only when blood pressure has reached a dangerously high level.

Diagnosis

• Blood Pressure Measurement: Using a sphygmomanometer to measure blood pressure over several visits.
• Ambulatory Blood Pressure Monitoring: Wearing a device that measures blood pressure at regular intervals over 24 hours.
• Home Blood Pressure Monitoring: Regular measurements at home to track blood pressure levels.

Blood Pressure Categories (in mm Hg)

• Normal: Systolic <120 and Diastolic <80
• Elevated: Systolic 120-129 and Diastolic <80
• Hypertension Stage 1: Systolic 130-139 or Diastolic 80-89
• Hypertension Stage 2: Systolic ≥140 or Diastolic ≥90
• Hypertensive Crisis: Systolic >180 or Diastolic >120 (requires immediate medical attention)

Treatment and Management

• Lifestyle Changes:
• Diet: Eating a balanced diet low in salt (DASH diet), rich in fruits, vegetables, whole grains, and lean proteins.
• Exercise: Regular physical activity, such as 150 minutes a week of moderate-intensity exercise.
• Weight Management: Maintaining a healthy weight.
• Reducing Alcohol Intake: Limiting alcohol to moderate levels.
• Quitting Smoking: Smoking cessation to improve overall cardiovascular health.
• Stress Management: Techniques such as relaxation, meditation, and yoga.
• Medications:
• Diuretics: Help the kidneys remove sodium and water.
• ACE Inhibitors: Relax blood vessels by blocking the formation of a natural chemical that narrows blood vessels.
• Angiotensin II Receptor Blockers (ARBs): Relax blood vessels by blocking the action of a natural chemical that narrows blood vessels.
• Calcium Channel Blockers: Prevent calcium from entering the heart and blood vessel cells, relaxing blood vessels.
• Beta-Blockers: Reduce the workload on the heart and open blood vessels.
• Other Medications: Alpha-blockers, alpha-2 receptor agonists, central agonists, peripheral adrenergic inhibitors, and vasodilators.

Monitoring and Follow-up

Regular check-ups with a healthcare provider to monitor blood pressure and adjust treatment as needed are crucial. Home monitoring can also help track progress and ensure blood pressure remains within a healthy range.

Effective management of hypertension involves a combination of lifestyle changes, medication, and regular monitoring to prevent complications and improve overall health.
