1000+ verified doctorsWhat Is eGFR, and Why Is It Important for Kidney Health? - #15270
I recently had a blood test, and my doctor mentioned something about my eGFR (estimated Glomerular Filtration Rate). I wasn’t sure what it meant, so I started researching. From what I understand, eGFR measures how well the kidneys are filtering waste from the blood, but how exactly is this number calculated? I read that a normal eGFR is usually above 90, but anything below 60 could indicate kidney disease. Does eGFR automatically decrease with age, or does it only drop when kidney function is impaired? What are the early warning signs of kidney problems that someone should watch out for if their eGFR is low? Are symptoms like fatigue, swelling, high blood pressure, or frequent urination common? I also came across information that eGFR can be improved naturally. Are there lifestyle changes, dietary habits, or Ayurvedic remedies that can help improve kidney function and possibly increase eGFR levels? I’ve read that Punarnava, Gokshura, and Triphala are good for kidney detoxification—do they really work? If anyone has been diagnosed with low eGFR, what changes did you make to improve your kidney health? Were dietary modifications enough, or did you need medication as well?

eGFR (estimated Glomerular Filtration Rate) is a test used to assess kidney function by measuring how well your kidneys are filtering waste from the blood. It’s calculated based on factors like your age, sex, race, and serum creatinine levels, which are a byproduct of muscle metabolism. A normal eGFR is typically above 90, but anything below 60 for three months or more could indicate chronic kidney disease (CKD). While eGFR can naturally decline with age, it usually only drops significantly when there is impaired kidney function, often due to conditions like high blood pressure, diabetes, or kidney disease. Early warning signs of kidney problems include fatigue, swelling, high blood pressure, frequent urination, and changes in the color or amount of urine.
To support kidney health, lifestyle changes such as reducing salt intake, staying hydrated, managing blood pressure and blood sugar levels, and avoiding excessive use of over-the-counter painkillers can help improve kidney function. In Ayurveda, herbs like Punarnava, Gokshura, and Triphala are believed to aid kidney detoxification, improve renal health, and support filtration processes. While these herbs may support kidney health, it’s important to combine them with a healthy diet and medical guidance. If you have low eGFR, dietary modifications such as reducing protein intake and increasing antioxidants can be beneficial, but more advanced stages may require medication or treatment prescribed by a doctor. Regular monitoring of kidney function is essential for managing any underlying conditions.
eGFR is indeed a crucial marker for assessing how well your kidneys are filtering waste from your blood. It estimates kidney function based on a blood creatinine test, age, gender, and sometimes race. As you mentioned, normal eGFR levels are generally above 90. Below 60 could indicate potential chronic kidney disease, which is when things start getting dicey.
About your question on age, yes, eGFR can naturally decrease with age. It’s common, but a significantly low drop might suggest underlying kidney issues. Symptoms like fatigue, swelling, high blood pressure, or frequent urination can be warning signs, although they may not appear until the kidney function is significantly reduced, which complicates early detection sometimes.
Improving eGFR naturally through Ayurveda is certainly possible. Lifestyle changes, diet, and herbal remedies can support kidney health. For dietary aspects, keep hydrating—water helps kidneys detoxify efficiently but stay aware of electrolytes. Avoid excess salt and processed foods, they’re hard on the kidneys.
As for herbs, Punarnava is great for kidney function, reducing swelling, and balancing fluid. Gokshura too, it supports urinary function. Triphala aids digestion and helps detoxify the body, although it’s more general. You can take these in specific formulations - but it’s best to see an Ayurvedic practitioner who can tailor remedies based on your unique dosha balance and health needs.
Your diet should focus on reducing fats and proteins - too much can strain the kidneys. Opt for more whole foods like fresh fruits and vegetables. Avoid meat, alcohol, and caffeine, as they can be taxing on the kidneys.
Many people with low eGFR have successfully managed their condition with these natural methods. Still, sometimes medication is necessary, especially if you’ve got other conditions like diabetes or high blood pressure. Be sure to consult with healthcare providers if making significant changes, so they can monitor your kidney function and overall health effectively.
Hope this gives you a clearer picture and you find the right balance for your health!
