Introduction
If low glomerular filtration rate is caused by nephrotoxic medications such as anti-infective or pain-relieving drugs, it generally returns gradually to normal after discontinuation or replacement of the medication. However, if it results from chronic kidney diseases such as chronic glomerulonephritis or hypertensive kidney damage, it usually causes permanent kidney function impairment, and in severe cases may progress to uremia, which is irreversible.
A low glomerular filtration rate (GFR) may or may not be reversible, depending on the underlying cause. The specific analysis is as follows:
1. Mild cases
If the decreased GFR is caused by nephrotoxic medications such as anti-infective agents or painkillers, it usually can gradually return to normal after discontinuing the medication or switching to an alternative drug.
2. Severe cases
If the low GFR results from chronic kidney diseases such as chronic glomerulonephritis or hypertensive kidney damage, it typically causes permanent impairment of kidney function. As the disease progresses, disturbances in water-electrolyte and acid-base balance may occur. In severe cases, this can advance to uremia, which is irreversible.
Patients with a low glomerular filtration rate should seek timely medical evaluation to determine the cause and receive appropriate treatment.
