50% high BP patients may suffer from kidney damage: Doctors
New Delhi, May 16
About 50 per cent of people with high blood pressure (BP) or hypertension are likely to experience kidney damage in the long term and may require dialysis or transplantation, said experts on Thursday ahead of World Hypertension Day.
“Uncontrolled hypertension may narrow, harden or weaken the arteries around the kidneys disturbing the kidney’s process of filtering blood, regulating fluid and electrolytes in the body. Hypertension damages the blood vessels and filters in the kidney, and it is challenging to remove waste from the body,” said LH Suratkal, nephrologist at Lilavati Hospital.
“Unmanaged hypertension causes scarring of kidney tissue kidney failure or end-stage renal disease (ESRD) leading to negative outcomes and deaths. About 30 per cent of people with hypertension tend to suffer from kidney damage in the long run and may require dialysis or transplantation,” he added
High BP is also known to affect the heart, brain, and eyes. According to health experts, a sedentary lifestyle, obesity, physical inactivity, and stress have increased the burden of hypertension in young Indians aged 15 to 60.
“The number of patients suffering from kidney disorders is increasing. About 80 to 100 patients come for treatment every month. Of those patients who come for treatment with kidney problems, 50 to 75 per cent are found to have hypertension,” said Ruju Gala, consultant nephrologist and renal transplant physician at Zynova Shalby Hospital in Mumbai.
The doctor explained that hypertension wreaks havoc on the kidney structure by straining the blood vessels in the kidneys and causing nephrosclerosis, where the kidneys become hard and their ability to filter waste products declines
“Hypertension also leads to an imbalance in the hormones and enzymes involved in managing blood pressure and maintaining fluid balance in the kidneys,” said Ruju.
As per the World Health Organisation (WHO), if half of the people with hypertension in India keep blood pressure under control, at least 4.6 million deaths can be averted by 2040.
To manage hypertension, the experts advised eating a nutritious diet, reducing sodium intake, maintaining an optimum weight, quitting smoking and alcohol, and avoiding intake of processed foods.
