Kidney disease is a medical condition that affects the kidneys’ ability to filter waste products and excess fluid from the blood. Healthy kidneys help maintain the body’s fluid balance, regulate minerals, control blood pressure, and support red blood cell production. When the kidneys become damaged, waste products and excess fluid may build up in the body.

Kidney disease can develop suddenly or progress gradually over time. In its early stages, it may not cause noticeable symptoms, making regular health check-ups important for people at higher risk. Early diagnosis, appropriate treatment, and lifestyle changes can help protect kidney function and reduce the risk of complications.
What is Kidney Disease?
Kidney disease refers to conditions that affect the structure or function of one or both kidneys. The kidneys filter blood, remove waste through urine, balance fluids and electrolytes, and help regulate blood pressure.
One common form is chronic kidney disease (CKD), in which kidney damage or reduced kidney function persists over time. Kidney disease may also develop suddenly, as in acute kidney injury, which can require urgent medical attention.
The severity of kidney disease varies. Some people have mild kidney damage and few symptoms, while others experience progressive loss of kidney function. Advanced disease may lead to kidney failure, for which dialysis or a kidney transplant may be necessary.
Symptoms of Kidney Disease
Kidney disease may not cause symptoms during its early stages. As kidney function declines, symptoms may become more noticeable.
Common symptoms include:
- Swelling: Puffiness around the eyes or swelling in the feet, ankles, legs, or hands due to fluid retention.
- Changes in urination: Urinating more often, particularly at night, or noticing changes in urine volume.
- Foamy urine: Urine that appears unusually foamy may indicate protein leakage.
- Blood in the urine: Urine may appear pink, red, brown, or tea-coloured.
- Fatigue and weakness: Waste accumulation or associated anaemia may contribute to tiredness.
- Loss of appetite: Some people experience reduced appetite, nausea, or vomiting.
- Shortness of breath: Fluid accumulation or anaemia may contribute to breathing difficulties.
- Itchy or dry skin: Changes in mineral balance and waste removal can cause skin symptoms in advanced disease.
- Muscle cramps: Changes in fluid or electrolyte balance may contribute to cramping.
- Difficulty sleeping: Discomfort, itching, or other complications may interfere with sleep.
- Difficulty concentrating: Some people with advanced kidney disease experience problems with attention or concentration.
These symptoms do not necessarily mean that a person has kidney disease. However, persistent symptoms, blood in the urine, or unexplained swelling should be evaluated by a healthcare professional.
Causes of Kidney Disease
Kidney disease can develop due to several medical conditions, inherited disorders, infections, or kidney damage.
- Diabetes: Diabetes is one of the leading causes of chronic kidney disease. Persistently high blood sugar can damage the small blood vessels inside the kidneys, gradually reducing their filtering ability.
- High Blood Pressure: Uncontrolled high blood pressure can damage the blood vessels in the kidneys. Kidney damage can also make blood pressure more difficult to control, creating a cycle that may worsen the condition.
- Glomerulonephritis: Glomerulonephritis involves inflammation of the glomeruli, the tiny filtering units within the kidneys. It may develop due to immune system disorders, infections, or other underlying conditions.
- Kidney Infections: Severe or recurrent kidney infections may damage kidney tissue, particularly when treatment is delayed or an underlying urinary tract problem is present.
- Urinary Tract Obstruction: Conditions such as kidney stones, an enlarged prostate, or structural abnormalities can obstruct the flow of urine. Significant or prolonged obstruction can damage the kidneys.
- Inherited Kidney Disorders: Some kidney conditions, such as polycystic kidney disease, are inherited and may cause cysts to develop in the kidneys, affecting their function over time.
- Certain Medicines: Some medicines can injure the kidneys, particularly when taken inappropriately, in excessive doses, or by people who already have reduced kidney function. Frequent use of certain painkillers, including non-steroidal anti-inflammatory drugs (NSAIDs), may increase the risk.
- Acute Kidney Injury: Severe dehydration, serious infections, major blood loss, certain medicines, or other acute medical problems can cause a sudden decline in kidney function. Acute kidney injury requires prompt assessment and treatment.
- Family History and Other Risk Factors: A family history of kidney disease, cardiovascular disease, and increasing age may raise the risk of developing kidney problems. Diabetes and high blood pressure are particularly important risk factors.
Types of Kidney Disease
Kidney disease includes several conditions that affect the kidneys in different ways.
- Chronic Kidney Disease (CKD): Chronic kidney disease is a long-term condition in which kidney damage or reduced kidney function persists. It may progress slowly and can eventually lead to kidney failure.
- Acute Kidney Injury (AKI): Acute kidney injury is a sudden decline in kidney function. It may occur over hours or days and can result from dehydration, severe illness, reduced blood flow to the kidneys, or certain medicines.
- Diabetic Kidney Disease: Diabetic kidney disease develops when diabetes damages the kidneys’ filtering structures. Managing blood sugar, blood pressure, and other risk factors is important to reduce further damage.
- Hypertensive Kidney Disease: This condition occurs when prolonged or poorly controlled high blood pressure damages the kidneys. Appropriate blood pressure management helps protect kidney function.
- Polycystic Kidney Disease: Polycystic kidney disease is an inherited condition in which fluid-filled cysts develop in the kidneys. Over time, these cysts may affect kidney function and cause complications.
- Glomerulonephritis: Glomerulonephritis affects the kidney’s filtering units and may lead to blood or protein in the urine, swelling, and reduced kidney function.
- Kidney Infection: A kidney infection, also called pyelonephritis, can cause fever, chills, pain in the back or side, and urinary symptoms. It generally requires prompt medical evaluation and appropriate antimicrobial treatment.
- Kidney Disease Due to Urinary Obstruction: Blocked urine flow may cause pressure to build up in the urinary tract and damage the kidneys. Treatment focuses on identifying and relieving the obstruction.
The appropriate treatment depends on the specific kidney condition, its severity, and the patient’s overall health.
Stages of Chronic Kidney Disease
Chronic kidney disease is commonly classified into five stages according to estimated glomerular filtration rate (eGFR), alongside other clinical findings. The stages help healthcare professionals assess kidney function and plan treatment.
| Stage | eGFR (mL/min/1.73 m²) | General description |
|---|---|---|
| Stage 1 | 90 or higher | Normal or high filtration with other evidence of kidney damage |
| Stage 2 | 60–89 | Mildly reduced filtration with other evidence of kidney damage |
| Stage 3a | 45–59 | Mild to moderately reduced filtration |
| Stage 3b | 30–44 | Moderately to severely reduced filtration |
| Stage 4 | 15–29 | Severely reduced filtration |
| Stage 5 | Below 15 | Kidney failure range |
Important: Stages 1 and 2 require evidence of kidney damage or another marker of kidney disease; eGFR alone does not establish the diagnosis. An eGFR below 60 that persists for at least three months may indicate chronic kidney disease. A single abnormal result is not always enough to confirm CKD. A healthcare professional interprets eGFR alongside urine tests, medical history, and other findings.
Diagnosis of Kidney Disease
Early kidney disease may have no noticeable symptoms, so testing is important for people with diabetes, high blood pressure, cardiovascular disease, or a family history of kidney disease.
1. Blood Test for Creatinine and eGFR
A blood test measures creatinine, a waste product normally removed by the kidneys. The result is used to estimate the glomerular filtration rate, which indicates how effectively the kidneys filter blood.
2. Urine Test for Protein
A urine test can detect albumin, a protein that may leak into urine when the kidneys are damaged. The urine albumin-to-creatinine ratio (UACR) is commonly used to assess this.
3. Urinalysis
Urinalysis may identify blood, protein, signs of infection, or other abnormalities in the urine.
4. Blood Pressure Measurement
High blood pressure is both a risk factor for kidney disease and a possible consequence of reduced kidney function. Regular measurement helps guide management.
5. Kidney Ultrasound
An ultrasound may be used to assess kidney size and structure, identify cysts, or investigate possible urinary obstruction.
6. Additional Tests
Depending on the suspected cause, the doctor may recommend additional blood tests, specialised urine tests, or a kidney biopsy.
The results help determine the cause and severity of kidney disease and guide an appropriate treatment plan.
Kidney Disease Treatment
Kidney disease treatment depends on its cause, stage, symptoms, and complications. The primary goals are to treat the underlying problem, protect remaining kidney function, and reduce the risk of further damage.
1. Managing Diabetes and Blood Pressure
Controlling blood sugar and blood pressure is essential for people whose kidney disease is associated with diabetes or hypertension. Regular monitoring and prescribed treatment can help slow disease progression.
2. Kidney-Protective Medicines
Depending on the patient’s condition, doctors may prescribe medicines that help control blood pressure, reduce protein leakage into urine, or protect kidney function. Some people may benefit from SGLT2 inhibitors or other medicines based on their diagnosis and clinical suitability.
3. Dietary Changes
A suitable diet may help control blood pressure, fluid balance, and mineral levels. Some people need to limit sodium, potassium, phosphorus, or protein, depending on their test results and stage of disease.
Dietary restrictions should be individualised. A kidney-friendly diet is not identical for every patient, and unnecessary restrictions can lead to nutritional problems.
4. Avoiding Kidney-Harming Substances
People with kidney disease should discuss all prescription medicines, over-the-counter drugs, supplements, and herbal products with their healthcare professional. Certain painkillers and unverified products may harm kidney function.
5. Treating the Underlying Cause
Treatment may include managing infections, relieving urinary obstruction, or treating specific inflammatory or inherited conditions. The appropriate approach depends on the diagnosis.
6. Dialysis
Dialysis may be required when kidney function becomes severely reduced and the kidneys cannot adequately remove waste products and excess fluid. It can help perform some functions of the kidneys but does not cure chronic kidney disease.
7. Kidney Transplant
A kidney transplant may be an option for eligible people with advanced kidney failure. It involves surgery and ongoing medical care, including medicines to reduce the risk of organ rejection.
Regular follow-up, laboratory testing, and adherence to the treatment plan are important for managing kidney disease.
Homeopathic Treatment for Kidney Disease
Kidney disease requires careful assessment because reduced kidney function can affect fluid balance, blood pressure, mineral levels, and the body’s removal of waste products. An appropriate care plan depends on the underlying cause, disease stage, and individual test results.
At Dr. Sanjay’s Homoeopathy, patients can discuss their health concerns, medical history, symptoms, lifestyle, and previous treatments during an individualized consultation. This can help them understand their concerns and discuss their overall healthcare needs.
For people experiencing symptoms or abnormal kidney-function results, timely medical assessment remains essential. In advanced kidney disease, delaying established treatment can lead to serious complications.
Homeopathic Remedies for Kidney Disease
In traditional homeopathic literature, some remedies are associated with urinary complaints and kidney-related symptoms. These traditional indications do not establish that the remedies treat kidney disease or improve kidney function.
Commonly mentioned remedies include:
1. Berberis Vulgaris
Traditionally associated with certain urinary complaints and discomfort around the kidney or lower back region.
2. Cantharis
Traditionally associated with burning or discomfort during urination.
3. Apis Mellifica
Traditionally associated with swelling and certain urinary complaints.
4. Lycopodium Clavatum
Traditionally associated with digestive and urinary symptoms in homeopathic practice.
5. Solidago Virgaurea
Traditionally associated with urinary complaints and kidney-related symptom patterns.
6. Pareira Brava
Traditionally associated with certain difficulties involving urination.
Lifestyle Tips for Kidney Health
Healthy daily habits can help reduce kidney-related risks and support the management of existing kidney disease.
- Control blood pressure: Check blood pressure regularly and follow your prescribed treatment plan.
- Manage blood sugar: If you have diabetes, monitor blood glucose and follow your healthcare professional’s recommendations.
- Reduce excess salt: Avoid excessive salt and highly processed foods, especially if you have high blood pressure or fluid retention.
- Follow an individualised diet: Ask your healthcare professional or renal dietitian whether you need to adjust protein, potassium, phosphorus, or other nutrients.
- Stay physically active: Choose regular physical activity appropriate for your health and abilities.
- Maintain a healthy weight: Weight management may help reduce the risk of diabetes and high blood pressure.
- Avoid smoking: Smoking increases cardiovascular risk and can contribute to poorer kidney health.
- Use medicines carefully: Do not regularly take over-the-counter painkillers or herbal supplements without checking whether they are safe for your kidneys.
- Attend regular check-ups: Follow recommended blood and urine testing schedules, especially if you have risk factors.
- Follow fluid advice: Do not force yourself to drink excessive water. People with advanced kidney disease or fluid retention may need an individual fluid plan.
These habits support kidney health but do not replace medical treatment for established kidney disease.
When to See a Doctor for Kidney Disease
Consult a healthcare professional if you experience persistent swelling, changes in urination, blood in the urine, unexplained fatigue, or other symptoms that may indicate kidney problems.
Medical evaluation is especially important if you have diabetes, high blood pressure, cardiovascular disease, or a family history of kidney disease, even if you feel well.
Seek urgent medical care if you experience:
- Very little or no urine.
- Severe shortness of breath or rapidly increasing swelling.
- Blood in the urine with severe pain or other concerning symptoms.
- Persistent vomiting with signs of dehydration.
- Fever and chills with pain in the back or side, particularly with urinary symptoms.
- Confusion, fainting, or a significant reduction in alertness.
These symptoms can have several causes, some of which require immediate treatment. Do not wait for a complementary therapy appointment if severe symptoms develop.
Frequently Asked Questions About Kidney Disease
What are the early symptoms of kidney disease?
Early kidney disease often causes no noticeable symptoms. Some people are diagnosed through routine blood and urine tests before symptoms develop.
What are the main causes of kidney disease?
Diabetes and high blood pressure are major causes of chronic kidney disease. Other causes include inflammatory kidney conditions, inherited disorders, infections, urinary obstruction, and acute kidney injury.
Can kidney disease be cured permanently?
The outcome depends on the type of kidney disease. Some causes of acute kidney injury may improve when treated promptly. Chronic kidney disease is often long-term, but appropriate treatment can help slow progression and manage complications.
How is kidney disease diagnosed?
Diagnosis usually involves blood tests for creatinine and eGFR, urine tests for albumin or blood, and assessment of blood pressure. Ultrasound and other investigations may be recommended when needed.
What is the difference between acute and chronic kidney disease?
Acute kidney injury develops suddenly, often over hours or days. Chronic kidney disease involves persistent kidney damage or reduced function over time, generally for at least three months.
Can kidney disease cause swelling in the feet and face?
Yes. Reduced kidney function may lead to salt and fluid retention, which can cause swelling in the feet, ankles, legs, or around the eyes. Other medical conditions can also cause swelling, so evaluation is important.
Is drinking more water good for kidney disease?
Not always. Fluid needs vary depending on kidney function, urine output, heart health, and fluid retention. Follow the fluid guidance provided by your healthcare professional rather than forcing yourself to drink excessive water.
What foods should be avoided in kidney disease?
There is no single diet suitable for everyone with kidney disease. Some people need to limit salt, potassium, phosphorus, or protein, while others may not require all these restrictions. A renal dietitian can help create an appropriate eating plan.
