When the kidneys lose their ability to filter and eliminate wastes, waste and body fluids rise to dangerous levels. The electrolytes and chemical makeup of the blood are also out of balance, as stated by Mayo Clinic. This condition is common in patients who are already in the hospital and who need intensive care treatment, as stated by Healthline.

Symptoms include bloody stools, swelling in the ankles and feet as the body accumulates fluid, high blood pressure, seizures and nausea.
