eGFR (Estimated Glomerular Filtration Rate)

eGFR, or Estimated Glomerular Filtration Rate, is a test that estimates the rate at which the kidneys filter waste from the blood. It is calculated based on serum creatinine levels, age, body size, and gender. eGFR is a crucial indicator of kidney function, helping to assess whether the kidneys are working effectively. A lower eGFR indicates poorer kidney function, which can signify kidney disease or damage....

Who would benefit from testing their eGFR levels?

Testing eGFR levels is beneficial for individuals at risk of kidney disease, such as those with diabetes, high blood pressure, heart disease, or a family history of kidney failure. It’s also important for older adults, as kidney function can decline with age. People who are taking medications that can affect kidney function should also monitor their eGFR regularly.

What are symptoms of low eGFR levels?

  • Swelling in the legs, ankles, feet, or face
  • Fatigue and weakness
  • Shortness of breath
  • Changes in urination (frequency, color, or consistency)
  • Nausea and vomiting
  • Difficulty concentrating or confusion
  • Loss of appetite

How do you improve your eGFR levels?

Improving eGFR levels involves managing any underlying conditions that are affecting kidney function. This can include controlling blood sugar levels in diabetes, managing blood pressure, reducing salt intake, and maintaining a healthy weight. Avoiding medications that can harm the kidneys and reducing the use of NSAIDs (non-steroidal anti-inflammatory drugs) can also help. Regular monitoring and maintaining a balanced diet with controlled protein intake are important in managing kidney health.

What factors affect your eGFR levels?

Several factors can affect eGFR levels. Chronic conditions like diabetes and high blood pressure can lead to a decrease in eGFR over time. Age is also a factor, as kidney function naturally declines with age. Certain medications, particularly those that can be toxic to the kidneys, can impact eGFR. Ethnicity and muscle mass can influence creatinine levels, and thus the eGFR calculation. Dehydration and acute illnesses can also temporarily affect kidney function and eGFR.
