Kidney problems can develop quietly, and symptoms often appear only after kidney function has changed significantly. Many of the signs below can also be caused by other conditions, so they are not a diagnosis on their own.

Your kidneys help filter waste, balance fluids, and regulate important body functions. Watch for these possible warning signs:
