One of the first signs of developing or existing kidney disorder could be swelling in the feet, ankles and legs that leave a dimple on the skin when pressure is applied, according to experts, due to too much fluid in the tissues. 

Doctors of King George's Medical University (KGMU) in Lucknow, have advised that those suffering from such problems should consult their doctors.

Head of nephrology department, Prof Vishwajeet Singh said, "Around 30 per cent of kidney patients come late and then, we have to rely on dialysis and or opt for kidney transplant. Despite this, we can detect kidney disease with two simple tests. These tests are free in many government hospitals and are available for minimal charges in medical institutes."
