eGFR Test - #18493

I recently heard about the eGFR test, and I want to understand what it is, why it is done, and whether Ayurveda offers natural ways to improve kidney function and prevent kidney disease. From what I read, eGFR (estimated Glomerular Filtration Rate) is a test used to measure how well the kidneys are filtering waste from the blood. It helps diagnose chronic kidney disease (CKD), kidney dysfunction, and overall renal health. A normal eGFR is above 90 mL/min/1.73m², while lower values indicate reduced kidney function or possible kidney disease. I do not have a diagnosed kidney condition, but I sometimes experience frequent urination, occasional lower back discomfort, and mild swelling in my feet, especially after eating too much salty food or not drinking enough water—could these be early signs of poor kidney function or a drop in eGFR levels? Does Ayurveda classify kidney dysfunction as a Vata or Kapha imbalance, and what are the best natural ways to improve kidney filtration and prevent kidney disease? Additionally, I want to know whether diet and hydration affect eGFR levels and kidney health. I consume a lot of processed foods and do not always drink enough water, and I have read that poor dietary choices and dehydration can reduce kidney efficiency—could my habits be affecting my kidney filtration rate? Does Ayurveda recommend specific herbs, diuretics, or kidney-cleansing therapies to support optimal eGFR levels and kidney detoxification? I have read that Punarnava, Gokshura, and Varuna are beneficial for improving kidney function, reducing water retention, and preventing kidney disease—would these help in naturally improving eGFR levels? Are there any Ayurvedic detox methods, herbal teas, or dietary modifications that can help in supporting kidney health and preventing chronic disease? Since I prefer natural kidney health solutions, I am looking for Ayurvedic treatments that can enhance kidney function, improve urine filtration, and maintain healthy eGFR levels naturally. Please provide detailed Ayurvedic insights on eGFR test, its significance, and Ayurvedic approaches to kidney health.
