HYPERTENSION

High Blood Pressure–Understanding the Silent Killer

Hypertension is called the "silent killer" because it typically has no symptoms while it quietly causes severe damage to your heart, brain, kidneys, and other organs, often until a sudden, catastrophic health crisis occurs. Hint: you cannot rely on symptoms to warn you. Proactive, regular check-ups are the essential defense against this silent threat.

DEFINITION:

Hypertension, or high blood pressure, is a condition where the force of your blood pushing against the walls of your arteries is consistently too high.

The Deadly Paradox:

The first "symptom" of uncontrolled hypertension is often a major, life-altering event—like a heart attack, stroke, or kidney failure. By the time you feel something, irreversible damage has already been done.

Risk and causes of hypertension

Biological Factors

• Age:

Prevalence increases sharply with age. Over 70% of adults aged 65+ have hypertension. However, research shows a concerning rise in prevalence among younger adults and even adolescents, linked to rising obesity rates and diet.



• Sex/Gender:

Younger Adults: Men are more likely to have hypertension than pre-menopausal women. Older Adults: Post-menopause, women's rates surpass those of men, and they often have poorer blood pressure control.



• Race/Ethnicity (with important socio-biological context):

More than one in four adults in Ghana have hypertension. This high prevalence has persisted for decades and is similar in rural and urban populations. With the low awareness and poor control of hypertension, greater investments in cardiovascular health are required if Ghana is to meet the global target for hypertension.



• Food Insecurity & Food Deserts:

Limited access to affordable fresh fruits/vegetables, high access to processed, high-sodium foods.



• Chronic Stress:

Linked to discrimination, financial insecurity, and unsafe neighborhoods. Stress activates physiological pathways that raise blood pressure.



• Lower Health Literacy & Access to Care:

preventive screenings, consistent treatment, and medication adherence.



• Environmental Factors:

Air and noise pollution are increasingly recognized as risk factors.

Behavioral & Modifiable Risk Factors

• Diet:

High sodium intake, low potassium intake (from fruits/vegetables), excessive alcohol consumption.



• Physical Inactivity:

A major driver of obesity and insulin resistance.



• Obesity & Adiposity:

Central (abdominal) obesity is a particularly strong risk factor.



• Smoking & Vaping:

Nicotine causes acute blood pressure elevation and damages arteries.



• Poor Sleep & Sleep Apnea:

Chronic sleep disruption is a significant and under-diagnosed contributor.

Genetic & Familial Risk

• Hypertension has a heritable component. Having a first-degree relative with hypertension increases an individual's risk.
• Most genetic research focuses on polygenic risk scores (many genes with small effects) rather than single-gene causes (which are rare).

Multiple Chronic Conditions,

People with certain conditions are disproportionately affected:

• Diabetes:

Hypertension and diabetes are frequently comorbid, sharing pathways like insulin resistance and exacerbating cardiovascular risk.



• Chronic Kidney Disease (CKD):

A classic bidirectional relationship—hypertension causes CKD, and CKD causes hypertension.



• Autoimmune & Inflammatory Diseases:

Conditions like lupus and rheumatoid arthritis increase risk. How to Beat the "Silent Killer" The good news is that it's detectable and controllable.
