CKD FAQ for UK Patients: eGFR, Creatinine, Diet and Stages

This UK-focused CKD FAQ brings together common questions about kidney function.

Is CKD the same as kidney failure?

No. CKD includes a wide range of kidney conditions and stages. Kidney failure generally refers to very severe loss of kidney function.

Is eGFR the same as kidney function?

eGFR is an estimate of filtration and is one part of kidney assessment. Urine ACR, trends and clinical history also matter.

Can creatinine alone diagnose CKD?

No. Creatinine needs to be interpreted in context and is commonly used to calculate eGFR.

Can CKD have no symptoms?

Yes. Early CKD may cause few or no obvious symptoms.

Does every person with CKD need a special diet?

No. Dietary advice depends on kidney function, blood results, medications and other conditions.

Does eGFR always fall every year?

No. Kidney function trends vary between people. Some remain stable while others change.

Can supplements be used with CKD?

Some supplements and herbal products can interact with medicines or be unsuitable in kidney disease. Discuss them with your healthcare professional.

Does an eGFR below 15 automatically mean dialysis?

No. Dialysis decisions depend on the overall clinical situation and specialist assessment.

Is coconut water good for the kidneys?

Coconut water is high in potassium. For most people it is a hydrating drink, but if you have reduced kidney function you may need to limit high-potassium foods and drinks — ask your renal dietitian or GP whether this applies to your specific results before making it a regular habit.

Is ginger good for kidney health?

Ginger is commonly used as a food and flavouring and is generally considered safe in normal culinary amounts. As with any food question in CKD, the answer can depend on your specific stage, potassium levels and other medicines — ask your healthcare team if you are using it more than as an occasional ingredient.

What does foam in urine or foamy urine mean?

Occasional light foam from a fast urine stream is usually normal. Persistent, heavy foam can sometimes indicate protein in the urine (proteinuria), which your GP can check with a simple urine ACR test. It is worth mentioning at your next appointment rather than diagnosing it yourself.

What is IgA kidney disease?

IgA nephropathy (sometimes called IgA kidney disease) is a specific cause of chronic kidney disease where a protein called IgA builds up in the kidneys' filtering units, which can lead to inflammation over time. It's diagnosed by a kidney specialist, usually via a biopsy, and management depends on your individual situation — ask your nephrologist how it applies to your own results.

Kidney disease symptoms in females: is there a difference?

The underlying warning signs of kidney disease are broadly similar between men and women, though some symptoms (such as changes noticed via urinary tract infections, or during pregnancy) may be first picked up in different contexts. Any new or unusual symptoms, in anyone, are worth discussing with your GP rather than trying to self-assess based on general lists.

What foods reduce creatinine?

There is no single food that reliably reduces creatinine on its own, and reducing protein intake without medical guidance can cause other problems. Any dietary change aimed at kidney results should be planned with a renal dietitian or your GP, based on your actual test results rather than the creatinine number alone.

Can Ayurveda replace kidney treatment?

Ayurveda should not be used as a replacement for appropriate medical diagnosis, monitoring, dialysis when clinically indicated or transplant assessment.

Nisarg Ayurveda provides complementary consultation and educational information for people who want to discuss Ayurvedic approaches alongside appropriate medical care.
