World Hypertension Day is observed on May 17th every year to educate the masses about the ill-effects of hypertension on the body. This year, the theme is ‘Measure your blood pressure accurately, control it, live longer’ which reflects on combatting low awareness rate and create more and more awareness about the disease and its management. According to a study published in the famous Lancet journal, India is ranked 156 and 164 globally in terms of hypertension prevalence among men and women respectively. Over two-third of the cases of chronic kidney disease in western countries are on account of high blood pressure and diabetes, the estimate in India is about 40–60% till today.

Our kidneys are both the victim and the cause of hypertension. High Blood pressure is one of the most common cause of kidney diseases today. Hypertension or high blood pressure causes damage to the tiny blood vessels that filters blood in the kidney, making removal of waste from the body difficult and thereby causing a damaged kidney. When the function of kidneys begins to fail, they can cause further increase in blood pressure by releasing certain hormones or by causing retention of salt and water in your body.

One who is hypertensive may not know that they have a kidney disease until their blood is tested for Blood Urea, Serum Creatinine and GFR. It is an extremely important parameter that every hypertensive individual should be tested for at least once in six months irrespective of their age to check for their renal function.
