Your kidneys even activate a form of vitamin D that improves the absorption of calcium.
When your kidneys can?t perform these functions due to disease or injury, dialysis can help keep the body running as normally as possible. Without dialysis, salts and other waste products will accumulate in the blood, poison the body, and damage other organs.
