Kidney failure disease refers to a severe loss of kidney function in which the kidneys can no longer adequately perform the functions needed to maintain the body's internal balance.
Healthy kidneys remove waste products and excess fluid from the blood while helping regulate electrolytes, acid-base balance, blood pressure and several important hormonal processes.
Kidney failure can develop suddenly, as in severe acute kidney injury, or gradually as a consequence of advanced chronic kidney disease.
The term "kidney failure" does not describe one single disease. It is the result of different underlying conditions, and identifying the cause is essential for appropriate treatment.
At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides individualized evaluation and management for patients with kidney disease and advanced kidney dysfunction.
What Causes Kidney Failure?
Kidney failure can have many causes.
Diabetes
Diabetes is a major risk factor for chronic kidney disease. Persistent high blood glucose can damage the kidney's filtering structures over time.
High Blood Pressure
Long-standing uncontrolled hypertension can damage the blood vessels within the kidneys and contribute to progressive loss of kidney function.
Severe Acute Kidney Injury
Kidney function can suddenly deteriorate because of:
-
Severe dehydration
-
Major infection
-
Low blood pressure
-
Significant blood loss
-
Certain medications or toxins
-
Urinary obstruction
-
Serious illness
Some cases of acute kidney injury can improve when treated promptly.
Glomerular Diseases
Conditions affecting the kidney's filtering units can cause inflammation, protein loss and progressive kidney damage.
Polycystic Kidney Disease
Inherited cystic kidney disorders can gradually enlarge and damage the kidneys and may eventually lead to advanced kidney disease.
Urinary Obstruction
Kidney stones, prostate-related obstruction, urinary strictures and other conditions can interfere with urine drainage.
If obstruction is severe or prolonged, kidney function can deteriorate.
Other Causes
Additional causes may include:
-
Autoimmune disorders
-
Recurrent kidney infections
-
Congenital kidney abnormalities
-
Repeated episodes of acute kidney injury
-
Certain inherited diseases
-
Long-term exposure to kidney-harming substances
In some patients, the exact cause may remain uncertain despite evaluation.
What Are the Symptoms of Kidney Failure?
Early kidney disease may have few obvious symptoms.
As kidney function becomes severely impaired, symptoms may include:
-
Persistent fatigue
-
Loss of appetite
-
Nausea or vomiting
-
Swelling of the feet, ankles or face
-
Reduced urine output
-
Changes in urination
-
Itching
-
Muscle cramps
-
Breathlessness
-
Difficulty concentrating
-
Sleep problems
-
Confusion in severe cases
These symptoms can occur in many other illnesses, so they do not establish kidney failure by themselves.
Blood and urine tests are essential for assessing kidney function.
Can Kidney Failure Develop Without Symptoms?
Yes.
Chronic kidney disease can progress silently for a long time.
A person may feel relatively well despite having significantly reduced kidney function.
This is particularly important for people with risk factors such as:
-
Diabetes
-
High blood pressure
-
Cardiovascular disease
-
Family history of kidney disease
-
Previous kidney injury
-
Recurrent kidney stones
Regular kidney-function testing can help identify disease before severe symptoms develop.
How Is Kidney Failure Diagnosed?
Doctors use several types of information to assess kidney function and determine the cause.
Serum Creatinine
Creatinine is a waste product that is normally removed by the kidneys.
When filtration decreases, creatinine may rise.
However, creatinine should be interpreted in context because factors such as muscle mass, hydration and certain medicines can influence the result.
eGFR
The estimated glomerular filtration rate helps estimate how effectively the kidneys filter blood.
A very low eGFR can indicate severe loss of kidney function.
Urine Tests
Urine examination may identify:
-
Protein
-
Albumin
-
Blood
-
Infection
-
Other abnormalities
Electrolyte Testing
Blood tests may assess:
-
Potassium
-
Sodium
-
Bicarbonate
-
Calcium
-
Phosphorus
Abnormal levels can occur when kidney function becomes severely impaired.
Imaging
Ultrasound or other imaging may help identify:
-
Kidney size
-
Urinary obstruction
-
Stones
-
Cysts
-
Structural abnormalities
Additional testing may be needed to determine the underlying kidney disease.
What Are the Stages of Chronic Kidney Disease?
Chronic kidney disease is commonly categorized according to eGFR.
| Stage | eGFR |
|---|---|
| G1 | 90 or higher |
| G2 | 60–89 |
| G3a | 45–59 |
| G3b | 30–44 |
| G4 | 15–29 |
| G5 | Less than 15 |
Stage 5 represents the most advanced category of chronic kidney disease.
However, an eGFR number alone does not determine whether a person needs dialysis.
Symptoms, electrolyte abnormalities, fluid status, acid-base problems, nutritional status and other clinical factors are also considered.
Is Kidney Failure the Same as Chronic Kidney Disease?
No.
Chronic kidney disease includes a broad range of persistent kidney abnormalities, from relatively mild impairment to advanced disease.
Kidney failure refers to severe loss of kidney function in which the kidneys can no longer adequately meet the body's needs.
Therefore, not everyone with chronic kidney disease has kidney failure.
Can Kidney Failure Be Reversed?
It depends on the cause.
Acute Kidney Failure
Some cases of acute kidney injury can improve substantially when the underlying cause is treated.
For example, kidney function may recover after appropriate treatment of dehydration, infection, obstruction or another reversible problem.
Chronic Kidney Failure
Long-standing kidney damage and scarring are generally not completely reversible.
However, appropriate treatment may help:
-
Preserve remaining kidney function
-
Control symptoms
-
Manage complications
-
Slow further progression
-
Improve quality of life
The possibility of recovery should be assessed individually.
Treatment for Kidney Failure Disease
There is no single treatment that applies to every patient.
Management depends on whether kidney failure is acute or chronic and on the underlying cause.
Treating the Underlying Condition
Doctors may address:
-
High blood pressure
-
Diabetes
-
Kidney inflammation
-
Infection
-
Urinary obstruction
-
Medication-related kidney injury
-
Electrolyte abnormalities
Managing Fluid Balance
Advanced kidney disease can cause fluid accumulation.
Treatment may involve dietary sodium reduction, fluid management, medicines or dialysis depending on the situation.
Managing High Potassium
Severely elevated potassium can be dangerous.
Treatment depends on the potassium level, symptoms, ECG findings and underlying cause.
Managing Anemia
Reduced kidney function can contribute to anemia.
Doctors may investigate iron status and other causes before deciding on appropriate treatment.
Managing Mineral and Bone Problems
Advanced kidney disease can disturb calcium, phosphorus and parathyroid hormone regulation.
These abnormalities may require dietary management, medicines and regular laboratory monitoring.
When Is Dialysis Needed?
Dialysis may be required when kidney function is severely impaired and complications cannot be adequately managed with other treatments.
Potential indications include:
-
Severe fluid overload
-
Certain dangerous electrolyte abnormalities
-
Significant acid-base disturbances
-
Uremic complications
-
Certain toxin exposures
-
Severe symptoms caused by kidney failure
Dialysis is not started solely because creatinine exceeds one particular number.
The nephrologist evaluates the entire clinical picture before recommending kidney replacement therapy.
What Is Hemodialysis?
Hemodialysis uses a specialized filter called a dialyzer to remove waste products and excess fluid from the blood.
Blood passes through the dialysis circuit and is then returned to the body.
A patient may require maintenance hemodialysis several times per week, depending on the individualized treatment plan.
Some patients may require dialysis temporarily if kidney function is expected to recover.
What Is Peritoneal Dialysis?
Peritoneal dialysis uses the lining of the abdomen, called the peritoneum, as a natural filtering membrane.
A dialysis solution is introduced into the abdominal cavity through a catheter and later drained.
Peritoneal dialysis can be performed using different schedules and may allow some patients to manage treatment at home.
The choice between hemodialysis and peritoneal dialysis depends on medical, practical and personal factors.
Is Kidney Transplant an Option?
For suitable patients with advanced kidney failure, kidney transplantation can provide an alternative to long-term dialysis.
A transplant involves placing a functioning donor kidney into the recipient.
Not every patient is medically suitable for transplantation.
Assessment may include evaluation of:
-
Heart health
-
Infection risk
-
Other medical conditions
-
Overall physical condition
-
Ability to follow post-transplant treatment
A transplant team can determine whether transplantation may be appropriate.
What Happens If Kidney Failure Is Left Untreated?
Severe untreated kidney failure can cause dangerous complications.
These may include:
-
Severe fluid overload
-
High potassium
-
Metabolic acidosis
-
Uremic symptoms
-
Heart complications
-
Severe weakness
-
Altered mental status
-
Breathlessness
-
Life-threatening deterioration
Advanced kidney failure requires specialist medical management.
Can Diet Help During Kidney Failure?
Dietary management can be an important part of treatment, but recommendations vary considerably.
Depending on kidney function and blood-test results, a patient may need to modify:
-
Sodium
-
Potassium
-
Phosphorus
-
Protein
-
Fluid intake
Patients on dialysis may have different nutritional requirements from those who are not receiving dialysis.
A renal dietitian can provide individualized dietary advice.
Should People With Kidney Failure Drink More Water?
No universal amount of water is appropriate for everyone with kidney failure.
People with advanced kidney disease may have reduced urine output and retain fluid.
Excessive fluid intake can contribute to:
-
Swelling
-
High blood pressure
-
Breathlessness
-
Fluid accumulation around or inside the lungs
Follow the fluid recommendation provided by your nephrologist.
How Can Kidney Failure Progression Be Reduced?
For people with chronic kidney disease, kidney-protection strategies may include:
-
Maintaining appropriate blood-pressure control
-
Managing diabetes
-
Taking prescribed kidney-protective medicines
-
Avoiding unnecessary NSAID painkillers
-
Reducing excessive sodium intake
-
Maintaining an appropriate body weight
-
Avoiding unverified supplements and "kidney detox" products
-
Treating urinary obstruction when present
-
Monitoring kidney function regularly
-
Following individualized dietary recommendations
Early management can be particularly important before kidney disease reaches an advanced stage.

Frequently Asked Questions
What is kidney failure disease?
Kidney failure is a severe loss of kidney function in which the kidneys can no longer adequately maintain the body's fluid, electrolyte and waste-removal requirements.
What are the first symptoms of kidney failure?
Early kidney dysfunction may cause few symptoms. Fatigue, swelling, changes in urination, nausea and reduced appetite may occur as disease becomes more advanced.
Can kidney failure be cured?
Some cases of acute kidney injury can improve when the cause is treated. Established chronic kidney failure generally cannot be completely reversed, but treatment can manage complications and support remaining kidney function.
Does high creatinine always mean kidney failure?
No. Creatinine can increase because of acute kidney injury, dehydration, urinary obstruction and other factors. It must be interpreted alongside eGFR, previous results and the clinical situation.
Does everyone with kidney failure need dialysis?
Not necessarily at the same time or for the same duration. Dialysis is recommended when kidney function is inadequate and complications or symptoms cannot be safely managed otherwise.
Can a kidney transplant replace dialysis?
For suitable patients, a successful kidney transplant can provide an alternative to long-term dialysis. Transplant suitability must be determined through specialist evaluation.
How can kidney failure be prevented?
Managing diabetes and blood pressure, avoiding unnecessary kidney-harming medicines, treating kidney disease early and attending regular follow-ups can help reduce the risk of progressive kidney damage.
Conclusion
Kidney failure disease represents severe loss of kidney function and can develop suddenly or gradually. Diabetes, high blood pressure, glomerular diseases, inherited kidney disorders, urinary obstruction and severe acute kidney injury are among the conditions that can contribute.
Because kidney disease may remain silent for years, people at increased risk should not wait for symptoms before having appropriate kidney-function testing. Creatinine, eGFR, urine tests, blood-pressure assessment and imaging can help establish the severity and possible cause.
Treatment ranges from addressing reversible causes and controlling chronic kidney disease to managing complications with dialysis or considering kidney transplantation when appropriate.
If you have persistently abnormal kidney-function tests, symptoms of advanced kidney disease or have been told that your kidneys are failing, specialist evaluation can help determine the most suitable treatment approach.
