Kidney Problems


Symptoms and Warning Signs of Kidney Diseases

The signs and symptoms seen in kidney problems depend on your particular condition. In many cases, you may have no physical warning that your kidneys are not working properly until the damage is quite advanced. This is why it is very important to schedule regular check-ups and regular screening exams with your healthcare provider.

Some symptoms that you or others may become aware of include: 

  • Fluid retention or swelling (edema) in the arms, legs, or belly
  • Increased or decreased need to urinate, including at night
  • Irregular heartbeats
  • Weakness and tiring easily
  • Cramps
  • Headaches
  • Nausea
  • Loss of appetite
  • Convulsions (seizures)
  • Loss of interest, depression, or confusion
  • Sudden sharp pains in the back or side (kidney stones)
  • Blood in the urine (hematuria), either microscopic, or visible to the naked eye as pink, red, or brown urine
  • High blood pressure that is suddenly very difficult to control
  • Weight loss
