Kidney failure occurs when the kidneys can no longer perform their essential functions adequately. The kidneys normally remove waste and excess fluid from the blood while helping maintain electrolyte, acid-base and blood-pressure balance.
When kidney function becomes severely reduced, a kidney failure patient may need regular medical monitoring and, depending on the clinical situation, kidney replacement therapy such as dialysis or transplantation.
Kidney failure is not identical in every person. The underlying cause, remaining kidney function, age, other health conditions, nutritional status and treatment goals all influence the care plan.
At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides evaluation and ongoing management for patients with kidney disease and advanced kidney failure.
What Happens When the Kidneys Fail?
Healthy kidneys continuously filter waste products and help regulate the body's internal environment.
As kidney function declines significantly, substances that would normally be removed through urine can accumulate.
A patient may develop:
-
Fluid retention
-
Swelling
-
Changes in urine output
-
High blood pressure
-
Electrolyte abnormalities
-
Acid-base disturbances
-
Anemia
-
Loss of appetite
-
Nausea
-
Fatigue
-
Itching
-
Sleep problems
-
Changes in concentration
The severity and combination of symptoms vary from person to person.
Common Causes of Kidney Failure
Kidney failure can result from several long-term or acute conditions.
Common causes include:
Diabetes
Diabetes can gradually damage the kidney's filtering structures and is a major cause of chronic kidney disease.
High Blood Pressure
Long-standing uncontrolled hypertension can damage kidney blood vessels and contribute to progressive loss of kidney function.
Glomerular Diseases
Certain diseases affecting the kidney's filtering units can cause significant protein loss and progressive kidney damage.
Polycystic Kidney Disease
This inherited condition causes multiple kidney cysts and can eventually impair kidney function in some individuals.
Recurrent or Severe Kidney Problems
Repeated obstruction, infections associated with structural abnormalities or other kidney injuries can contribute to long-term damage.
Acute Kidney Injury
A severe episode of acute kidney injury may sometimes lead to persistent loss of kidney function, particularly in people with pre-existing kidney disease.
Symptoms a Kidney Failure Patient May Experience
Advanced kidney disease can produce symptoms when waste products and fluid accumulate.
Possible symptoms include:
-
Persistent tiredness
-
Reduced appetite
-
Nausea or vomiting
-
Swelling of the legs or feet
-
Puffiness around the eyes
-
Breathlessness
-
Itching
-
Muscle cramps
-
Sleep disturbances
-
Changes in urine output
-
Difficulty concentrating
-
Metallic taste in the mouth
-
Unpleasant breath
-
High blood pressure
Some patients may have relatively few symptoms despite significantly reduced kidney function, which is why laboratory monitoring is important.
How Is Kidney Failure Diagnosed?
Doctors use several measurements to understand kidney function.
Blood Tests
Common investigations include:
-
Serum creatinine
-
eGFR
-
Blood urea
-
Sodium
-
Potassium
-
Bicarbonate
-
Calcium
-
Phosphorus
-
Hemoglobin
The results help assess kidney function and detect complications.
Urine Tests
Urine testing may evaluate:
-
Protein
-
Albumin
-
Blood
-
Infection
-
Other abnormalities
Imaging
Ultrasound or other imaging may be used to assess kidney structure, obstruction, cysts or other abnormalities.
The patient's symptoms, history and previous test results are considered together rather than relying on one laboratory value.
Treatment for a Kidney Failure Patient
Treatment depends on the cause, severity and overall health of the patient.
Management may include:
-
Controlling blood pressure
-
Managing diabetes
-
Treating anemia
-
Managing electrolyte abnormalities
-
Treating mineral and bone complications
-
Managing fluid retention
-
Adjusting medications
-
Dietary counseling
-
Preventing further kidney injury
-
Preparing for dialysis when appropriate
-
Evaluating for kidney transplantation
Treatment should be individualized and regularly reviewed.
Does Every Kidney Failure Patient Need Dialysis?
Not necessarily.
Dialysis is considered when the kidneys are unable to adequately maintain the body's internal balance and clinical indications for kidney replacement therapy are present.
Doctors may consider factors such as:
-
Severe symptoms caused by kidney failure
-
Certain dangerous electrolyte abnormalities
-
Significant fluid overload
-
Acid-base disturbances
-
Certain toxin or waste accumulation
-
Overall clinical condition
The decision is based on the patient's overall medical picture rather than creatinine alone.
Types of Dialysis for Kidney Failure
There are two major forms of long-term dialysis.
Hemodialysis
During hemodialysis, blood is circulated through a dialysis machine where waste products and excess fluid are removed before the filtered blood returns to the body.
Treatment schedules vary depending on the patient's circumstances and dialysis plan.
Peritoneal Dialysis
Peritoneal dialysis uses the lining of the abdomen, called the peritoneum, as a filtering membrane.
Dialysis fluid is introduced into the abdominal cavity and later drained, removing waste and excess fluid.
The choice between dialysis options depends on medical suitability, lifestyle, home circumstances and patient preference.
Kidney Transplantation
For suitable patients with advanced kidney failure, a kidney transplant may offer an alternative to long-term dialysis.
A transplant involves placing a functioning donor kidney into the recipient.
Patients undergo detailed medical evaluation before transplantation to determine suitability and identify potential risks.
After transplantation, lifelong medical follow-up and anti-rejection medicines are generally required.
A kidney transplant is not appropriate for every patient, so an individualized transplant evaluation is essential.
Kidney Failure Patient Diet
Dietary needs change according to:
-
Remaining kidney function
-
Dialysis status
-
Potassium level
-
Phosphorus level
-
Sodium intake
-
Fluid status
-
Diabetes
-
Nutritional requirements
Depending on the individual's condition, a healthcare team may recommend adjustments to:
Sodium
Reducing excessive sodium can help manage blood pressure and fluid retention.
Potassium
Some patients with advanced kidney disease need to limit high-potassium foods if their blood potassium is elevated.
Phosphorus
Phosphorus management may become important in advanced CKD.
Protein
Protein requirements vary. Patients should not drastically reduce protein intake without professional advice, particularly those receiving dialysis.
Fluids
Some kidney failure patients require fluid restrictions, while others may not.
A renal dietitian can provide an individualized meal plan.
What Should a Kidney Failure Patient Avoid?
There is no universal list of foods or medicines that every kidney failure patient must avoid.
Depending on the medical condition, doctors may advise caution with:
-
Excessive salt
-
Unsupervised herbal remedies
-
Certain over-the-counter pain medicines
-
Unapproved supplements
-
Excessive fluid intake
-
Foods high in potassium or phosphorus when restriction is medically indicated
Never make major dietary changes without discussing them with the treating team.
Medicines Used in Kidney Failure
Medicines are selected according to the patient's specific complications.
Treatment may include medicines for:
-
Blood pressure
-
Diabetes
-
Anemia
-
Mineral and bone disorders
-
Fluid overload
-
Electrolyte abnormalities
-
Cardiovascular risk
-
Other underlying diseases
Because impaired kidney function changes how many medicines are processed or eliminated, medication doses may need adjustment.
Patients should tell their doctor about all prescription medicines, over-the-counter drugs, vitamins and supplements they use.
Importance of Blood Pressure Control
Blood pressure management is particularly important in people with kidney disease.
Uncontrolled hypertension can accelerate kidney damage and increase cardiovascular risk.
A kidney failure patient should follow the individualized blood pressure target recommended by their healthcare professional and take prescribed medicines consistently.
Diabetes Management in Kidney Failure
For patients whose kidney failure is related to diabetes, glucose management remains important.
However, medication requirements may change as kidney function declines.
Diabetes treatment should therefore be reviewed regularly rather than continuing medicines without reassessment.
Fluid Overload in Kidney Failure
When kidneys cannot remove enough fluid, excess fluid may accumulate.
Possible signs include:
-
Swelling of feet and ankles
-
Rapid weight gain
-
Breathlessness
-
Increased blood pressure
The treatment may involve dietary sodium reduction, fluid management, medication or dialysis depending on the severity.
Sudden or severe breathlessness requires urgent medical attention.
Anemia in Kidney Failure
Healthy kidneys produce erythropoietin, a hormone that contributes to red blood cell production.
Advanced kidney disease can reduce erythropoietin production and contribute to anemia.
A patient may experience:
-
Fatigue
-
Weakness
-
Reduced exercise tolerance
-
Breathlessness
-
Difficulty concentrating
Doctors may investigate iron status and other causes before determining appropriate treatment.
Kidney Failure and Bone Health
Advanced kidney disease can affect calcium, phosphorus and vitamin D metabolism.
This can contribute to chronic kidney disease-mineral and bone disorder (CKD-MBD).
Doctors may monitor:
-
Calcium
-
Phosphorus
-
Parathyroid hormone
-
Vitamin D-related parameters
-
Bone health
Treatment depends on laboratory findings and individual risk.
Emotional and Lifestyle Support
Living with kidney failure can affect daily routines, work, family responsibilities and emotional well-being.
Patients may benefit from:
-
Understanding their treatment plan
-
Maintaining regular medical appointments
-
Following dialysis schedules when prescribed
-
Discussing concerns with the healthcare team
-
Staying physically active when medically appropriate
-
Maintaining social connections
-
Seeking professional emotional support when needed
Family involvement can also make long-term treatment easier to manage.
Regular Monitoring Is Essential
Kidney failure management is not limited to treating symptoms.
Regular follow-up may involve monitoring:
-
Kidney function
-
Blood pressure
-
Electrolytes
-
Hemoglobin
-
Calcium and phosphorus
-
Body weight
-
Fluid status
-
Nutritional status
-
Medication effects
The frequency of testing depends on the patient's condition and treatment.
When Should a Kidney Failure Patient Seek Urgent Care?
Immediate medical evaluation may be necessary if a patient develops:
-
Severe breathlessness
-
Chest pain
-
Confusion or reduced consciousness
-
Seizures
-
Very low or absent urine output
-
Severe weakness
-
Persistent vomiting
-
Severe swelling
-
Sudden significant weight gain
-
Severe symptoms during or between dialysis sessions
Patients receiving dialysis should also follow the emergency instructions provided by their dialysis team.
Can a Kidney Failure Patient Live a Long Life?
Life expectancy varies considerably among people with kidney failure.
It depends on factors such as:
-
Age
-
Cause of kidney failure
-
Heart and blood-vessel health
-
Diabetes and other medical conditions
-
Nutritional status
-
Dialysis adequacy when applicable
-
Access to transplantation
-
Treatment adherence
-
Overall health
There is no single life-expectancy number that applies to every patient.
Appropriate treatment, regular monitoring and management of complications can make a significant difference to health and quality of life.

Frequently Asked Questions About Kidney Failure
What happens to a patient when the kidneys fail?
When kidney function becomes severely reduced, waste products, electrolytes and fluid can accumulate. Patients may develop symptoms and complications that require medical management and, in some cases, dialysis or transplantation.
Does every kidney failure patient need dialysis?
No. Dialysis is recommended when kidney function is insufficient and specific clinical indications are present. The decision is made by the treating medical team.
Can kidney failure be reversed?
Some acute kidney injuries can improve substantially if the underlying cause is treated promptly. Established chronic kidney failure is generally not completely reversible, although appropriate management can help control complications.
Can a kidney failure patient eat a normal diet?
Dietary requirements depend on kidney function, laboratory results, dialysis status and other medical conditions. A personalized renal diet is often more appropriate than a generic kidney diet.
Is kidney transplant better than dialysis?
For eligible patients, transplantation can provide an alternative to long-term dialysis and may offer benefits in survival and quality of life. However, suitability varies and requires comprehensive medical evaluation.
Can kidney failure patients drink plenty of water?
Not always. Some patients require fluid restriction because their kidneys cannot remove excess fluid effectively. Fluid recommendations should come from the treating healthcare professional.
Conclusion
Caring for a kidney failure patient requires more than treating a single symptom. Advanced kidney disease can affect fluid balance, blood pressure, electrolytes, blood counts, bones, nutrition and cardiovascular health.
Depending on the patient's condition, management may involve medicines, dietary adjustments, close monitoring, hemodialysis, peritoneal dialysis or kidney transplantation. Early planning and regular specialist care can help patients and families understand their options and make informed treatment decisions.
