What is GFR? (Complete & Essential Guide)

If you are wondering “What is GFR?”, you are already doing the right thing to safeguard your kidney function. GFR is an abbreviation for Glomerular Filtration Rate, which is an essential value that reveals how effectively your kidneys are working to remove waste products, toxins, and fluid from your blood.
In the USA and UK, GFR is one of the most reliable and latest measures that doctors use to identify kidney problems at an early stage. At Medilux Ayurveda, we strongly feel that knowing “What is GFR?” is the first step towards taking effective and natural measures to ensure good kidney function.

What is GFR and Why is It Important?

Your kidneys contain millions of tiny filters known as glomeruli. These filters help eliminate waste materials like creatinine and fluid from your blood. The amount of blood that passes through your filters in a minute is known as Glomerular Filtration Rate (GFR).
Normal GFR levels show that your kidneys are healthy.
Low GFR levels show that your kidneys are damaged or that you have Chronic Kidney Disease (CKD).
In the United States and the United Kingdom, blood tests always involve the measurement of eGFR (estimated GFR) to check the health of your kidneys.

What is eGFR?

When physicians respond to the question “What is GFR?,” they often begin with an explanation of eGFR, which stands for estimated GFR.
eGFR is calculated based on:
Blood levels of Creatinine, Age, Sex, Ethnicity. It is a very accurate and potent estimate of renal function that does not require invasive procedures.

Normal GFR Levels (USA & UK Standards)

Understanding what is GFR also includes knowing normal values:

According to NHS (UK) and CDC (USA) guidelines, a GFR below 60 for three months or more may indicate chronic kidney disease.

What Causes Low GFR?

When discussing what is GFR, it’s equally important to understand why it drops.

Common Causes in the USA & UK:

• Diabetes (Type 1 & Type 2)
• High blood pressure
• Obesity
• Long-term use of painkillers (NSAIDs)
• Kidney infections
• Autoimmune disorders

Lifestyle-related diseases are a major cause of declining GFR in Western countries.

Symptoms of Low GFR

There may be no symptoms in the early stages. But as the GFR gets lower, you may experience the following:
Fatigue
Swelling in the legs or ankles
Foamy urine
Frequent urination during the night
Difficulty breathing
Loss of appetite
If you are experiencing these symptoms, it is essential to seek a healthcare provider’s attention right away.

What is GFR Testing Process?

In the USA and UK, testing GFR is simple and widely available.

Step 1: Blood Test

A serum creatinine test measures waste levels in your blood.

Step 2: Calculation

Labs calculate eGFR using standardized formulas.

Step 3: Results Interpretation

Your doctor reviews your kidney function stage.

At Medilux Ayurveda, we encourage patients to combine modern diagnostics with holistic kidney care approaches.

Can GFR Be Improved?

The response depends on the underlying cause.
Dehydration
Acute kidney injury
Medication side effects
In these situations, GFR can be improved greatly.
 Chronic Kidney Disease:
If the kidney damage is chronic, then the emphasis is on slowing its progression.
