Kidney, Reproductive and Urinary Conditions

Kidney Failure Symptoms and Diagnosis

Symptoms of Kidney Failure

Your child may not show any symptoms of a problem with the kidneys until they are not doing their job and fail to remove waste.

When the kidneys aren't working well, symptoms are varied and may be the same as many other conditions. These symptoms include:

  • Urinating more often or less often
  • Feeling very tired
  • Losing appetite
  • Getting sick to the stomach or vomiting
  • Have swelling in hands or feet
  • Feeling itchy or numb
  • Having darkened skin
  • Having muscle cramps

Kidney Failure Diagnosis

Because some ongoing kidney problems do not have obvious symptoms, your child's doctor may find a disorder during routine tests or exams. If your child's doctor suspects there may be a problem with the kidneys, they may check:

  • Your child's blood pressure. High blood pressure can be a sign that the kidneys aren't working well.
  • The amount of a protein called albumin in your child's urine. Healthy kidneys filter wastes but leave behind protein in the blood. Protein in the urine may be a sign of trouble.
  • The amount of a waste product called creatinine in your child's blood. Healthy kidneys usually filter creatinine from the blood.
