Kidney problems do not develop overnight. Your kidney function naturally starts declining after you cross your 30s. And whether you will develop a kidney problem later in life is largely dependent on your lifestyle habits and diet. In most cases kidney problems are caused as a result of a primary condition like diabetes hypertension or high cholesterol levels. Because the symptoms of kidney diseases are not evident unless the kidneys are deteriorated to a great extent (to about 15 percent of their normal capacity) you should regularly screen your kidney function (especially if you suffer from heart disease and diabetes).
