How the Body Repairs Kidney Damage

Kidneys can regenerate some tissue, but not indefinitely.
Mild damage can heal if the cause—like dehydration—is corrected quickly.
Specialized cells in nephrons can repair microtears and restore function.
Severe injury causes scar tissue, which limits long-term recovery.
A balanced diet and hydration support natural healing processes.
Inflammation control helps protect remaining healthy tissue.
New research focuses on stem cell therapy for kidney regeneration.
Early detection gives the body the best chance to self-repair.
Chronic damage, however, usually requires medical intervention.
With care, even partially damaged kidneys can keep working for years.
