Kidney failure and injury occur when the kidneys stop functioning and fail to filter waste products out of the blood, explains MedicineNet. A person with kidney problems commonly experience confusion, weakness, shortness of breath and abnormal heart beat. In some cases, it can even cause death.

The kidneys fail due to a variety of reasons, some of which can be treated, says MedicineNet. For instance, low blood volume, dehydration, rapid water loss and a renal obstruction can cause the kidneys to fail. These situations can be remedied with proper hydration or a removal of the blockage. Some diseases overwhelm the immune system, causing the kidneys to shut down. There are medications such as antibiotics, iodine medications and anti-inflammatory drugs that, if taken incorrectly, can harm the kidneys.
