The kidneys manage essential bodily functions, cleaning the blood of waste and toxins and transforming that waste into urine. The kidneys lie deep inside the abdomen, on either side of the spine, which is why kidney infections can cause pain in the back or side. Though it is possible to live with only one kidney, taking care of these organs is essential to preserving health and preventing the serious diseases malfunctioning kidneys can cause.


1. What Do the Kidneys Do?

Our kidneys perform many functions to keep the blood free of waste and eliminate excess water, making them as life-sustaining as the heart, lungs, and liver. When the kidneys are not working as they should, this build-up waste and excess water can cause headaches, lethargy, fluid retention, and other more serious symptoms such as shortness of breath, abnormal heart rhythm, and even death.
