Around 30–45% of adults worldwide have hypertension, with higher rates in low- and middle-income countries
Introduction
Hypertension, or high blood pressure, is a leading global health concern. It affects over 1.3 billion people worldwide and is often referred to as the “silent killer” due to its lack of symptoms until complications arise. Hypertension is a major risk factor for cardiovascular diseases (CVD), stroke, kidney failure, and premature mortality.
Burden of Hypertension
Global Impact
- Prevalence: Around 30–45% of adults worldwide have hypertension, with higher rates in low- and middle-income countries.
- Morbidity and Mortality: Hypertension is responsible for an estimated 10.8 million deaths annually.
- Economic Impact: The condition imposes substantial healthcare costs due to its complications, including hospitalizations, medications, and lost productivity.
In the United States
- Nearly half of all adults (116 million) have hypertension.
- Only about 1 in 4 individuals have their condition under control.
Etiology of Hypertension
Hypertension arises from a combination of genetic, environmental, and lifestyle factors.
Primary (Essential) Hypertension
- Definition: Accounts for 90–95% of cases with no identifiable medical cause.
- Risk Factors:
- Age: Blood pressure typically increases with age.
- Genetics: Family history of hypertension increases risk.
- Lifestyle factors: Poor diet, sedentary lifestyle, and obesity.
Secondary Hypertension
- Definition: Caused by an underlying condition, accounting for 5–10% of cases.
- Common Causes:
- Kidney disease
- Hormonal disorders (e.g., Cushing’s syndrome, hyperaldosteronism)
- Sleep apnea
- Certain medications (e.g., oral contraceptives, NSAIDs)
Health Complications of Hypertension
Chronic high blood pressure can damage organs and lead to severe health conditions:
1. Cardiovascular Disease
- Heart Attack and Heart Failure: Excessive pressure strains the heart, leading to left ventricular hypertrophy and eventual heart failure.
- Aneurysms: Persistent high pressure can weaken arterial walls.
2. Stroke
Hypertension increases the risk of ischemic and hemorrhagic strokes by damaging blood vessels in the brain.
3. Chronic Kidney Disease (CKD)
Elevated blood pressure damages the renal arteries, impairing kidney function and potentially leading to kidney failure.
4. Vision Loss
Hypertension can damage the blood vessels in the eyes, leading to hypertensive retinopathy and, in severe cases, blindness.
5. Cognitive Decline
High blood pressure is associated with an increased risk of vascular dementia and Alzheimer’s disease.
Dietary and Lifestyle Changes to Manage or Eliminate Hypertension
1. Dietary Interventions
Adopt the DASH Diet
- Overview: The Dietary Approaches to Stop Hypertension (DASH) diet emphasizes heart-healthy eating.
- Key Components:
- Fruits, vegetables, whole grains, and lean proteins
- Low-fat dairy products
- Reduced sodium intake
- Limited saturated fats and trans fats
Reduce Sodium Intake
- Recommendation: Limit sodium to less than 2,300 mg/day; ideal intake is 1,500 mg/day.
- Sources to Avoid: Processed foods, canned soups, and salty snacks.
Increase Potassium-Rich Foods
- Sources: Bananas, spinach, sweet potatoes, and avocados.
- Mechanism: Potassium helps balance sodium levels and reduce blood pressure.
Limit Alcohol Consumption
- Guideline: No more than one drink per day for women and two for men.
Maintain a Healthy Weight
- Mechanism: Weight loss reduces strain on the cardiovascular system and lowers blood pressure.
2. Lifestyle Modifications
Increase Physical Activity
- Guidelines:
- 150 minutes of moderate-intensity aerobic exercise per week.
- Include resistance training to improve overall heart health.
- Examples: Brisk walking, cycling, swimming, and strength training.
Stress Management
- Techniques:
- Meditation, yoga, or deep breathing exercises.
- Engaging in hobbies and maintaining social connections.
Quit Smoking
- Smoking damages blood vessels and exacerbates hypertension risks.
Improve Sleep Quality
- Recommendations:
- 7–9 hours of restful sleep per night.
- Address sleep disorders like sleep apnea.
Limit Caffeine
- While effects vary, reducing caffeine can benefit those sensitive to its blood-pressure-raising effects.
