High Blood Pressure: The Silent Killer

High blood pressure is a major cause of premature death worldwide, with an estimated 1.4 billion adults aged 30-79 years worldwide affected in 2024, representing 33 percent of the population in this age range. According to the World Health Organisation, hypertension occurs when the pressure in your blood vessels is too high (140/90 mmHg or higher), and it is common but can be serious if left untreated. Dr Brian Hoeflinger, a neurosurgeon with 26 years of experience from Ohio in the US, warns that high blood pressure is known as the 'silent killer' because it often doesn't show any symptoms, and people can go years without knowing they have the condition until a severe health issue arises.

Key Takeaways:

• High blood pressure is a major cause of premature death worldwide, affecting 1.4 billion adults aged 30-79 years worldwide in 2024, representing 33 percent of the population in this age range.
• Hypertension occurs when the pressure in your blood vessels is too high (140/90 mmHg or higher), and it is common but can be serious if left untreated.
• Dr Brian Hoeflinger warns that high blood pressure is often asymptomatic, and people can go years without knowing they have the condition until a severe health issue arises.
• Elevated blood pressure damages the blood vessel lining, leading to plaque buildup, known as atherosclerosis, which narrows vessels and reduces blood flow to vital organs.
• This can cause fatal heart attacks or strokes, and almost 50 percent of individuals with high blood pressure don't experience symptoms.
• Regular monitoring of blood pressure is crucial to prevent severe health issues.
• Dr Santosh Kumar Dora, consultant cardiologist at Mumbai's Asian Heart Institute, recommends lifestyle modifications to lower blood pressure naturally, such as adopting a healthy diet low in sodium, exercising regularly, maintaining a healthy weight, limiting alcohol consumption, and managing stress.
