Answer : 1. "A kidney disorder that causes excessive protein in the urine."
Explanation :

Researchers from Kerala have linked regular use of fairness creams to nephrotic syndrome. Nephrotic syndrome is a kidney disorder in which there is excessive protein in the urine due to glomeruli inflammation. Healthy kidneys filter waste but inflamed glomeruli leak protein into the urine. It is not a specific kidney disease but can result from a variety of conditions that damage the kidney filters. Diseases such as nephritis, diabetes and lupus can trigger nephrotic syndrome, affecting both the kidneys and other organs in the body.
