What Does a eGFR (Estimated Glomerular Filtration Rate) Level of 37 mL/min/1.73m² Mean?
Imagine your kidneys as a pair of highly efficient water filters for your body. They constantly clean your blood, removing waste products and extra fluid, which then leave your body as urine.
The eGFR (Estimated Glomerular Filtration Rate) is like a measure of how efficiently these filters are working. If your eGFR (Estimated Glomerular Filtration Rate) is 37 mL/min/1.73m², it suggests that your kidneys are filtering blood at a rate lower than what is generally considered full efficiency.
Think of it this way: if a brand-new, high-performance filter can clean 100 gallons per hour, a filter operating at 37 mL/min/1.73m² is working at less than half that capacity.
This doesn't mean the filters are completely broken; rather, they are performing at a noticeably reduced level compared to optimal function. This measurement helps healthcare professionals understand how well your kidneys are removing toxins and maintaining balance within your system, guiding conversations about potential changes or areas for attention.
The National Kidney Foundation emphasizes the importance of understanding your eGFR (Estimated Glomerular Filtration Rate) value as a key indicator of kidney health and overall filtration capacity, providing a basis for comparison against typical population data.
A decline in glomerular filtration rate to approximately 37 mL/min/1.73m² often points to chronic kidney disease (CKD) that has progressed. The most probable underlying causes in this scenario are long-standing, poorly controlled diabetes mellitus, which damages the small blood vessels in the kidneys, or hypertension, which exerts excessive pressure on the delicate filtering units.
Less commonly, autoimmune conditions like lupus nephritis or certain genetic disorders affecting kidney structure can lead to this level of impairment. Significant long-term exposure to nephrotoxic medications, such as certain NSAIDs or specific antibiotics, can also contribute to this degree of kidney function decline.
Lifestyle Changes for eGFR (Estimated Glomerular Filtration Rate) 37 mL/min/1.73m²
Beyond dietary considerations, daily habits play a significant role in supporting overall health and kidney function, even with an eGFR (Estimated Glomerular Filtration Rate) of 37 mL/min/1.73m².
