High Blood Pressure and its consequences
If you have high blood pressure, then this higher pressure can definitely put extra strain on your brain and blood vessels.
Over time, this extra strain will increase your risk of a heart attack or stroke. High blood pressure can also cause heart and kidney disease and later affect your health.
The number of people having this problem of high blood pressure across the globe has almost doubled over the past four decades.
“High blood pressure is the leading risk factor for stroke and heart disease, and kills around 7.5 million people worldwide every year,” said lead author Professor Majid Ezzati from Imperial College in London.
Moreover, between 1975 and 2015, the tally of adults who are having high blood pressure rose from 594 million to over 1.1 billion, according to the overview which was published in The Lancet medical journal.
High income countries shown impressive reductions
At the same time, high income countries such as Canada, Australia, Germany and Japan have made “impressive reductions” in the prevalence of high blood pressure, the study found.
In the year 2015, more than half of all adults having high blood pressure—some 590 million people—were living in east, southeast and south Asia. Of that number, 226 million were found in China and 199 million in India.
Around a third of woman living in most West African countries also suffer from high blood pressure.
According to the World Health Organization (WHO), blood pressure is also considered as high when it rises to 140/90 and over.
Ezzati said that without further introducing “effective policies” which has allowed the poorest to improve their diet, particularly by reducing salt intake and making fruit and vegetables affordable, the WHO’s 2025 target of reducing high blood pressure cases by 25 percent was “unlikely to be achieved”.
At the other end of the scale, Canada, Australia, Britain and the United States, Peru, South Korea and Singapore had the lowest proportion of the adults living with high blood pressure in the year 2015, with around or fewer than one in eight women and one in five men affected.
The data used in the study had come from 19.1 million people, who were aged 18 or older, living in 200 countries.
