How long can a glomerular filtration rate of 70 be maintained?

The lifespan of a patient with a glomerular filtration rate (GFR) of 70ml/min cannot be generalized and requires consideration of factors such as the patient's age, disease type, and severity of illness. For most patients, if the underlying disease can be actively treated, their lifespan may not be significantly impacted.

GFR, as an indicator of kidney function, is closely related to the health status of the kidneys. In normal adults, the GFR is approximately 125ml/min. Typically, a decrease in GFR is accompanied by a decline in kidney function. For a GFR of 70ml/min, if there is no significant disease progression or complications, the prognosis may be favorable, and the survival period may be relatively long. However, if the cause of the decreased GFR is a severe disease such as glomerulonephritis, diabetic nephropathy, or hypertensive nephropathy, the survival period may be affected, and timely treatment and intervention may be necessary.

GFR is typically evaluated by measuring serum creatinine levels, along with factors like age, gender, and weight, using the CKD-EPI formula. A GFR of 90-120ml/min is considered Chronic Kidney Disease (CKD) Stage 1, indicating normal kidney function. A calculated GFR of 70ml/min suggests a mild decrease in GFR, which allows for early detection of kidney disease by monitoring changes in GFR and assessing the severity and prognosis of the disease.

Patients with a GFR of 70ml/min should seek medical attention promptly and undergo regular kidney function tests to identify potential diseases.
