You probably don't often think about your kidneys -- your body's filtration system --, but you need to think about them and protect them as well. Your kidneys are situated in your lower back. They have a vital function of filtering your blood of excess substances while ensuring that you retain the right amount of water and electrolytes for normal functioning. But certain conditions can damage the filters in your kidneys, causing a progressive decrease in the kidney's ability to filter blood. This may result in the accumulation of toxins in your bloodstream and can eventually lead to renal failure, a severe condition that must be treated immediately. Therefore, it is essential always to follow specific recommendations to care and preserve their functions. This way, you'll be preventing kidney damage and thus kidney failure. This little book contains some practical tips on how you can reduce your risk and prevent kidney failure now and in future.
