World Hypertension Day is observed every year on 17 May to raise awareness about the “silent killer” that affects 188.3 million people in India.

"Uncontrolled high blood pressure can narrow, harden or weaken the arteries around the kidneys, which can disrupt the kidneys' process of filtering blood and regulating fluids and electrolytes in the body. High blood pressure can damage the blood vessels and filters in the kidneys. “It causes damage to the kidneys, and it is challenging to remove waste from the body,” L H Suratkal, nephrologist at Lilavati Hospital, told IANS.

“Unmanaged high blood pressure causes scarring on the kidney tissue.Renal failure leads to negative outcomes and death due to end-stage renal disease (ESRD). About 3 percent of people with high blood pressure suffer long-term kidney damage and may require dialysis or a transplant. ," He added

High BP is known to affect the heart, brain and eyes as well. According to health experts, sedentary lifestyle, obesity, physical inactivity and stress have increased the burden of hypertension among young Indians aged 15-60 years.

Consultant Ruju Gala said, “The number of patients suffering from kidney disorders is increasing.Every month around 8 to 100 patients come for treatment. Of the patients who come for treatment of kidney problems, 50 to 75 per cent are found to have high blood pressure," Nephrologist and Renal Transplant Physician Zinova Shalby Hospital Mumbai told IANS.

The doctor explained that high blood pressure wreaks havoc on the structure of the kidneys and puts pressure on the blood vessels in the kidneys and causes nephrosclerosis, where the kidneys become stiff and their ability to filter out waste products is reduced.

"High blood pressure also causes imbalances in hormones and enzymes involved in controlling blood pressure and maintaining fluid balance in the kidneys," Ruju said.,

According to the World Health Organization (WHO), if half of the people suffering from hypertension in India kept blood pressure under control, at least 4.6 million deaths could be prevented by 2040.

To manage high blood pressure, experts recommend eating a nutritious diet, reducing sodium intake, maintaining optimal weight, quitting smoking and alcohol, and avoiding processed foods.
