Your guide to eGFR.
Understand the importance of estimated Glomerular Filtration Rate (eGFR) in your health and longevity with Mito Health's comprehensive biomarker analysis. Our detailed reports cover key biomarkers, providing essential insights to help you make informed decisions for a healthier, longer life.
What is eGFR?
Estimated Glomerular Filtration Rate (eGFR) is a calculated measure of kidney function, representing the rate at which the kidneys filter waste and excess fluid from the blood.
It’s an estimate of the glomerular filtration rate (GFR), which is the volume of blood filtered per minute by the kidney’s glomeruli, tiny filtering units within the kidneys.
What does it assess?
Estimated Glomerular Filtration Rate (eGFR) is a measure of kidney function, specifically indicating how well the kidneys filter waste from the blood.
It is calculated using serum creatinine levels, age, sex, and sometimes other factors like race. Regular monitoring of eGFR can help detect early signs of kidney impairment, assess disease progression, and guide treatment decisions.
eGFR is a vital marker for assessing kidney health, and optimizing kidney function through lifestyle, diet, and monitoring is essential for maintaining a healthy eGFR.
How do I optimize my eGFR?
Diabetes is another major cause of kidney damage. Proper blood sugar control through a balanced diet and exercise helps protect kidney function and maintain a healthier eGFR.
Adequate hydration supports kidney function by helping them filter waste efficiently. Aim for consistent fluid intake throughout the day but avoid excessive water intake, which can strain the kidneys.
While protein is important for muscle health, excessive intake, especially from animal sources, can stress the kidneys. Similarly, high sodium intake can increase blood pressure, negatively affecting kidney health.
Aim for moderate protein intake and limit processed foods to reduce sodium.
What does having a high and low eGFR mean?
High eGFR levels suggest healthy kidney function. However, eGFR above a certain threshold may not be clinically significant. Extremely high eGFR values may rarely occur in situations where creatinine levels are low, but generally, high eGFR is not a cause for concern.
Low eGFR levels often indicate reduced kidney function. A consistently low eGFR calls for medical evaluation to determine the cause of kidney impairment, potential underlying conditions, and appropriate treatment steps to slow progression.
