Keeping the co-relation between the two in view, the theme for this year’s World Kidney Day (March 9) is ‘Obesity and Kidney disease: Healthy lifestyle for healthy kidneys’.

For every one point increase in BMI, the risk for developing chronic kidney disease (CKD) goes up by 7-10 per cent. Among those coming to us with kidney ailments, we find out of every 10 patients 3-4 are overweight and obese. People of all ages can be afflicted by kidney disease but those in their 20s and 30s are also at risk besides children as obesity is noticed among the young generation as well.”
