Understanding Kidney Glomerular Filtration Rate (GFR) and Its Role in Kidney Health

The glomerular filtration rate (GFR) is a crucial indicator of kidney function. It is a measure of how well the kidneys filter waste and excess fluids from the blood. GFR provides important insights into the health of your kidneys and is an essential test in diagnosing kidney diseases. At Medilux Ayurveda, we believe in the best approach of Ayurveda to improve kidney health and support the body’s detoxification processes. Understanding GFR levels, their significance, and how to maintain normal GFR can greatly contribute to better kidney health.

In this article, we will explore the concept of GFR, the normal GFR range, the GFR normal range for age, the role of eGFR (estimated GFR), and how Ayurveda can help improve kidney health and restore normal GFR levels.

What Is Glomerular Filtration Rate (GFR)?

Glomerular filtration rate (GFR) is a test used to measure how well the kidneys are working, specifically how well they filter blood. It indicates the amount of blood the kidneys filter per minute and helps determine how efficiently the kidneys are removing waste products and excess fluids from the bloodstream. A healthy GFR indicates normal kidney function, while a low GFR may signal kidney damage or chronic kidney disease (CKD).

The kidneys are responsible for filtering approximately 120 to 150 quarts of blood every day, removing waste products, and excreting them in the form of urine. The glomeruli, which are tiny clusters of blood vessels in the kidneys, are responsible for filtering blood. GFR essentially measures how much blood passes through these glomeruli every minute.

A normal GFR is essential for maintaining fluid, electrolyte, and acid-base balance in the body. When the kidneys are not functioning optimally, the GFR can decrease, leading to the buildup of waste and toxins in the blood.

Glomerular Filtration Rate (GFR) Normal Range

The normal GFR range is not a fixed number because it varies depending on several factors such as age, gender, body size, and race. However, a GFR of 90 mL/min/1.73m² or higher is generally considered normal for healthy individuals. As we age, however, the GFR tends to decline naturally, and this should be considered when interpreting GFR levels.

GFR Normal Range for Age

As people age, kidney function naturally declines, and so does the GFR normal range for age. It’s important to keep in mind that a slight decrease in GFR with age doesn’t necessarily indicate kidney disease, but it does require attention to maintain kidney health. Below is a general guide to GFR normal values by age:

• Age 18-29 years: Normal GFR is typically 90-120 mL/min/1.73m².
• Age 30-39 years: Normal GFR is typically 90-110 mL/min/1.73m².
• Age 40-49 years: Normal GFR is typically 80-100 mL/min/1.73m².
• Age 50-59 years: Normal GFR is typically 70-90 mL/min/1.73m².
• Age 60-69 years: Normal GFR is typically 60-80 mL/min/1.73m².
• Age 70+ years: Normal GFR can decline to 50-70 mL/min/1.73m².

It is important to note that these are approximate ranges, and GFR should always be assessed alongside other health factors such as medical history, underlying conditions, and symptoms.

How GFR Is Measured: eGFR vs. GFR

GFR can be measured directly or estimated indirectly through a blood test. The direct method is used in specialized tests where a substance is injected into the body to measure how much of it is filtered by the kidneys. However, in routine clinical practice, eGFR (estimated GFR) is used.

eGFR (Estimated GFR)

eGFR is a calculated estimate of the GFR, derived from a blood test that measures the level of creatinine, a waste product produced by muscles. Creatinine levels can help estimate kidney function. The eGFR is calculated using a formula that factors in age, gender, race, and creatinine levels.

A normal eGFR level is typically 90 mL/min/1.73m² or higher, although it can vary depending on age. If the eGFR is less than 60 mL/min/1.73m² for three months or more, it is generally indicative of chronic kidney disease (CKD).

eGFR Levels Chart

To make it easier to interpret eGFR results, doctors often refer to an eGFR levels chart, which classifies kidney function into stages of CKD:

• eGFR 90 or above: Normal kidney function (with no signs of kidney disease).
• eGFR 60-89: Mild kidney dysfunction (often asymptomatic but requires monitoring).
• eGFR 30-59: Moderate kidney dysfunction (potential for kidney damage and need for treatment).
• eGFR 15-29: Severe kidney dysfunction (requires immediate intervention, such as dialysis or transplant).
• eGFR below 15: Kidney failure (requires dialysis or kidney transplant).

The eGFR levels chart helps healthcare providers determine the best course of action for treatment, especially if there are signs of declining kidney function.

Factors That Can Affect GFR

Several factors can influence GFR levels and cause fluctuations in kidney function. These include:

1. Age: Kidney function naturally declines with age, which can lower GFR.
2. Gender: Men usually have higher GFR levels compared to women due to differences in muscle mass and body size.
3. Race: Certain races, such as African Americans, may have higher muscle mass and, therefore, different GFR values.
4. Muscle Mass: Since creatinine is produced by muscles, individuals with higher muscle mass may have naturally higher creatinine levels and potentially higher GFR levels.
5. Medications: Certain medications can impact kidney function and, consequently, GFR.
6. Other Conditions: Conditions like diabetes, hypertension, or obesity can contribute to kidney damage, which may cause a decrease in GFR.

Why GFR is Important

The glomerular filtration rate is a vital metric for assessing kidney health because it helps to detect kidney dysfunction in its early stages. A decline in GFR can indicate underlying kidney disease, even before symptoms are noticeable. Early detection allows for early intervention, which can significantly reduce the risk of kidney failure and the need for dialysis.

Ayurvedic Approach to Improving GFR and Kidney Function

At Medilux Ayurveda, we believe in addressing the root cause of kidney dysfunction through holistic and natural methods. Ayurveda offers a safe and effective way to support kidney health and maintain normal GFR levels. Ayurvedic treatment focuses on detoxifying the body, balancing the doshas (Vata, Pitta, and Kapha), and enhancing kidney function through herbs, dietary changes, and lifestyle modifications.

Key Ayurvedic Herbs for Kidney Health

Several Ayurvedic herbs are known to promote kidney health and improve glomerular filtration rate. Some of these include:

1. Punarnava (Boerhavia diffusa): Known for its diuretic properties, Punarnava helps reduce swelling and inflammation in the kidneys, promoting better kidney function and fluid balance.
2. Gokshura (Tribulus terrestris): This herb supports kidney function by improving circulation and reducing inflammation.
3. Varuna (Crataeva nurvala): Varuna is known for its ability to support kidney health, especially in conditions related to urinary tract health and fluid retention.
4. Kanchanar (Bauhinia variegata): Kanchanar is effective in reducing kidney cysts and promoting healthy kidney tissue.
5. Ashwagandha (Withania somnifera): A powerful adaptogen, Ashwagandha helps reduce stress, which can have a positive effect on kidney health.

Panchakarma for Kidney Detoxification

Panchakarma, a specialized Ayurvedic detoxification therapy, helps cleanse the body of accumulated toxins (Ama), reduce inflammation, and enhance kidney function. Procedures like Basti (medicated enema) and Virechana (purgation) are particularly beneficial for people with kidney dysfunction, as they help cleanse the kidneys and improve their filtering capacity.

Dietary Recommendations

Diet plays a crucial role in Ayurvedic treatments for kidney health. An anti-inflammatory, kidney-friendly diet helps support GFR and improve kidney function. Some dietary suggestions include:

• Increase fluid intake: Drink adequate water and herbal teas such as Gokshura or Punarnava tea to support kidney detoxification.
• Reduce sodium: Excess salt can put a strain on the kidneys, so limit salt intake to maintain fluid balance.
• Include anti-inflammatory foods: Include turmeric, ginger, garlic, and green leafy vegetables in your meals to reduce inflammation.
• Avoid processed foods: These foods can burden the kidneys and exacerbate kidney issues.

Conclusion

The glomerular filtration rate (GFR) is a key indicator of kidney health, and understanding the GFR range and its implications for kidney function is essential for preventing and managing kidney disease. Normal GFR levels can vary depending on age, gender, and other factors, but it is important to monitor GFR regularly to detect any signs of kidney dysfunction.
