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
