Final answer:
An eGFR less than 60 is indicative of chronic kidney disease, meaning there's a significant decline in kidney function, which may lead to various health complications and requires medical attention.
Step-by-step explanation:
The term eGFR stands for estimated Glomerular Filtration Rate, and it is a measure of how well the kidneys are filtering waste from the blood. An eGFR less than 60 mL/min/1.73 m² for a duration of 3 months or more is concerning because it can indicate chronic kidney disease (CKD). A decline in kidney function to this level represents a loss of half or more of the adult level of normal kidney function.
CKD is associated with various complications, such as cardiovascular disease, anemia, bone disease, increased risk of infections, and poorer health outcomes overall. It is crucial for individuals with a reduced eGFR to seek medical guidance to manage the condition and potentially slow the progression of kidney disease. This includes lifestyle changes, medications, and regular monitoring of kidney function.
