Kidney Failure
Sometimes the kidneys don’t work well.

They lose their ability to filter wastes out of your blood, they don’t produce urine the way they should, and excess wastes and chemicals start to build up in the body. This buildup of wastes and extra fluid will make you feel tired.

If your kidneys don’t work, this is known as kidney failure or end-stage renal disease (ESRD). Without treatment (that is, dialysis or a kidney transplant), the buildup of toxins, extra fluid, and dangerous levels of minerals in your blood will eventually cause death.
