When the kidneys fail (also called renal failure), these things can happen:

  • Harmful wastes build up causing headaches, decreased appetite, nausea and vomiting
  • Excess fluid collects, causing swelling in the legs and feet—this is known as edema
  • Blood pressure often rises
  • Your child can become anemic—anemia is a condition caused by too few red blood cells in the body, which causes your child to feel weak and tired
  • Your child may have insomnia (not sleep well)
  • Your child may not grow and develop normally
