Chronic kidney disease stage 3 is a moderate decline in renal function with a GFR of 30-59 ml/(min-1.73m²), which is more severe and requires regular treatment.
Chronic kidney disease is defined as renal injury (abnormal renal structure or function) for ≥3 months, either with or without a decrease in glomerular filtration rate (GFR), which is clinically manifested by abnormal pathologic tests or renal injury (including abnormalities in blood or urine composition or abnormalities in imaging tests); or a GFR of <60 ml/(min-1.73m²) for ≥3 months, with or without evidence of renal injury.
A GFR of 30-59 ml/(min-1.73m²) suggests chronic kidney disease stage 3, which is more severe, and patients with chronic kidney disease stage 3 are more critical and require regular treatment. Most have been definitively diagnosed, and the relevant complications and cardiovascular events begin to appear significantly, especially in stage 3b.
In addition to searching for treatable causes of chronic kidney disease stage 3, correcting reversible factors, preventing or delaying the progression of renal function, reducing cardiovascular risk, and treating complications such as anemia are also the focus of treatment.
Patients with chronic kidney disease stage 3 should go to the hospital in time and receive regular treatment under the guidance of professional physicians.
