In general, once kidney function is lost or significantly impaired, it is not possible for the kidneys to fully recover to their previous state. The term "chronic kidney disease" (CKD) is used to describe a progressive and irreversible loss of kidney function over time. However, the progression of kidney disease can be slowed, and supportive measures can be taken to manage the condition and improve the quality of life for the affected individual. Early detection, appropriate management, and lifestyle modifications can help slow the progression of kidney disease and potentially delay the need for more aggressive interventions such as dialysis or kidney transplantation. Medications, dietary changes, fluid therapy, and other treatments can be implemented to support kidney function and manage the underlying causes contributing to kidney disease. In some cases, if kidney disease is caused by a treatable underlying condition (such as a urinary tract infection or certain medication-induced kidney damage), addressing and resolving that condition may lead to an improvement in kidney function. However, complete restoration of normal kidney function is rare once significant damage has occurred.
