At a Glance

High blood pressure, also known as hypertension, is one of the leading causes of heart disease, stroke, kidney disease, and premature death worldwide. It often develops without obvious symptoms, which is why it is commonly known as the "silent killer."

Many women live with high blood pressure for years without knowing they have it. Regular blood pressure checks, healthy lifestyle choices, and early treatment can significantly reduce the risk of serious health complications.

The good news is that hypertension can often be prevented, detected early, and effectively managed.

What is High Blood Pressure?

Blood pressure is the force of blood pushing against the walls of your arteries as your heart pumps.

When this pressure remains consistently too high, your heart and blood vessels have to work harder than normal.

Over time, this extra strain can damage:

• The heart

• The brain

• The kidneys

• The eyes

• Blood vessels throughout the body

Because high blood pressure rarely causes symptoms in its early stages, regular monitoring is essential.

Why It Matters for Black African Women

High blood pressure affects Black African women at disproportionately higher rates than many other populations.

Several factors contribute to this increased risk, including:

• Family history

• Higher rates of obesity

• Diabetes

• Chronic stress

• Limited access to preventive healthcare

• Dietary habits, particularly high salt intake

• Pregnancy-related hypertension

• Socioeconomic inequalities

Earlier diagnosis and effective management can dramatically reduce the risk of stroke and heart disease.

Signs and Symptoms

Most people experience no symptoms.

When symptoms do occur, they may include:

• Persistent headaches

• Blurred vision

• Dizziness

• Shortness of breath

• Chest discomfort

• Nosebleeds (occasionally)

• Fatigue

• Heart palpitations

Symptoms usually appear only when blood pressure becomes dangerously high.

Lifestyle Factors

• Too much salt in the diet

• Physical inactivity

• Excess alcohol

• Smoking

• Obesity

• Chronic stress

Medical Conditions

• Diabetes

• Kidney disease

• Sleep apnoea

• High cholesterol

Non-Modifiable Risk Factors
