Can creatinine levels return to normal with treatment?

Yes, depending on the cause, creatinine levels can return to normal with appropriate treatment. For example, if dehydration is causing elevated creatinine, rehydration can quickly bring levels back to normal. In cases of kidney disease or injury, treatment such as medications, dietary changes, and lifestyle adjustments can help stabilize kidney function and reduce creatinine levels. However, in advanced stages of chronic kidney disease (CKD), creatinine levels may remain elevated, and the focus shifts to managing the disease and slowing its progression.
