Chronic Kidney Disease (Renal Failure) :Cause, Symptoms, and Best Treatment

What is Kidney failure or Chronic Kidney Disease? 

A Chronic Kidney disease also known as renal failure, occurs when one or both kidneys quit working. Acute kidney injury, also known as AKI, is a rare form of kidney failure that can strike certain individuals unexpectedly. In other patients, chronic kidney disease, also known as CKD, is a condition that can develop gradually over time.

It is estimated that 2 million individuals globally experience renal failure, and the number of new cases of the illness is rising at a pace of 5-7% per year. Nausea, vomiting, decreased urine production, dry or itchy skin, disorientation, hallucinations, and a metallic aftertaste to meals are some of the symptoms of renal failure. Although kidney failure can be a dangerous medical disease, it can be addressed if a patient seeks treatment on time. Dialysis and the right drugs to address the underlying causes and symptoms of renal failure are the cornerstone of treatment. When a kidney is failing, a kidney transplant is typically the last option. A patient suffering from renal failure would need ongoing medical supervision and routine check-ups.

Cause of Kidney Failure

Chronic Kidney Disease

Renal failure can be caused by the following three primary factors:

1. illnesses that slow down or restrict the blood flow to your kidneys

These are the illnesses and ailments that have the potential to impede kidney blood flow and eventually cause damage to the kidneys. They are as follows:

  • Failure of the liver
  • Fluid or blood loss
  • Infections
  • Heart conditions
  • Heart attack
  • Severe allergic reaction
  • using drugs like ibuprofen and naproxen sodium
  • severe burns
  • severe dehydration
  • prescription drugs for high blood pressure

2. illnesses that prevent pee from leaving your kidneys

The following are the situations that cause reduced urine flow:

  • Cancer of the bladder, colon, cervical, or prostate
  • An enlarged prostate
  • bladder nerve damage
  • kidney stones
  • Blood clots were seen in your urinary tract
  1. Circumstances and factors that cause harm to your kidneys directly

Kidney damage can be caused by:

  • cholesterol buildup
  • The existence of thrombi
  • pharmaceuticals such as antibiotics or non-steroidal anti-inflammatory medications (NSAIDs), such as ibuprofen and naproxen
  • The illness known as glomerulonephritis causes inflammation in the kidney’s small filters.
  • chemotherapy
  • infection or sepsis
  • Rhabdomyolysis is the process by which the breakdown of muscle tissue releases the contents of the muscle fibers into the bloodstream.
  • Hemolysis is the disintegration or death of red blood cells.
  • harm to the nerves controlling your bladder
  • Used in radiography techniques, iodinated contrast

Additionally, renal failure can also result from the following other causes:

  • An autoimmune condition called lupus can cause inflammation in several body organs.
  • toxicity from heavy metals
  • Vasculitis is the name of an inflammatory blood vessel disease.
  • Hemolytic uremic syndrome is an infection-related condition that causes red blood cells to lyse.
  • Scleroderma is an autoimmune skin disease
  • Unmanaged diabetes
  • dyes used in certain imaging procedures
  • Multiple myeloma, a bone-resident malignancy of plasma cells
  • renal polycystic disease

Symptoms Of Kidney Failure


Patients may not even be aware that they have early-stage renal failure because the symptoms are frequently minor. As per the Centers for Disease Control and Prevention (CDC), as many as 90% of people who have chronic renal disease are not even aware that they have the illness. The indications and symptoms of renal failure typically worsen over time.

Among the signs of renal failure are the following:

  • The symptoms of fluid retention include
  • Swelling in the feet, legs or ankles;
  • excessive sleepiness;
  • and heightened weariness.
  • Breathlessness;
  • decreased urination;
  • chronic nausea;
  • chest discomfort or pressure;
  • muscle spasm;
  • metallic taste;
  • irregular heartbeat;
  • irregular sleep patterns;
  • back pain; fever; rash;
  • diarrhea;
  • abdominal pain;
  • seizures;
  • coma

Early indicators of renal failure are less obvious and include the following signs and symptoms:

  • Breathlessness;
  • Limb swelling brought on by fluid retention;
  • Less urine production
  • Urine color changes can serve as an early warning indicator of kidney injury and the subsequent progression of the illness.
  • Pale yellow or clear urine: This is usually the optimal color and shows that your body is properly hydrated.
  • Amber or dark yellow pee: Your urine may appear darker than usual if you don’t drink enough water. Reducing your intake of soda, tea, and coffee while increasing your fluid intake will help cure this sign of dehydration.
  • If you observe that your urine has a pink or crimson tone, you should be concerned. The crimson hue could indicate a medical problem, which could be blood. Urine that is crimson can also be caused by eating foods like strawberries or beets. In such cases, see your doctor and request a urine test.
  • Orange-colored urine: This could also be a sign of dehydration. It may be a sign that your bloodstream has collected bile. Kidney disease is typically not the source of orange-colored urine.
  • Foamy pee: This could mean that there is protein in the urine, which could be an indication of kidney disease.

Kidney Failure Types:

There are two types of kidney failure:

Acute renal failure, sometimes referred to as acute kidney damage or acute failure, is a rapidly progressing medical illness that can be treated, frequently in a matter of days. It usually affects those who are already in the hospital, particularly those who are very sick.

Chronic renal failure: This type progresses gradually over a minimum of three months and can result in irreparable kidney damage. The patient may experience few symptoms in the early stages of chronic kidney disease and may not become aware of the illness until it has progressed.

Kidney Failure Risk Factors

Kidney failure typically occurs in conjunction with other illnesses or due to another disease. Kidney failure is more likely to occur if:

  • have long been admitted to the hospital
  • Got admitted to the intensive care unit
  • experience cardiac failure
  • possess elevated blood pressure
  • possess uncontrolled diabetes
  • Take NSAIDs and other painkillers daily.
  • possess either liver disease or chronic renal disease
  • possess coronary artery disease
  • are aged

Identification of renal failure

Your doctor can diagnose acute renal failure with the aid of several tests. Among the typical examinations are the following ones:

  1. Analyzing urine

You could be requested to provide a urine sample for your doctor to arrange a urinalysis. Your doctor will order the test if they see anything unusual, such as strange proteins or sugar in the urine. A lab is tasked with analyzing the urine sample. Red and white blood cells, quantities of bacteria, and many tube-shaped bacteria known as cellular casts are all found with a urine sedimentation test. Sometimes glomerulonephritis (swelling and redness of the small filters in the kidneys called glomeruli), vasculitis (inflammation of the blood vessels), or toxins cause extremely severe proteinuria (>3.5 g/d). The role of urine eosinophils in differential diagnosis is limited. They are seen in cases of glomerulonephritis, other embolic disease, cystitis (bladder inflammation), pyelonephritis (urinary tract infection), and interstitial nephritis (swelling of the spaces between the kidney tubules). Also, they are seen in cases of urinary tract infections.

When oxalate crystals are seen in cases of acute renal damage, ethylene glycol toxicity should be assessed.

  1. Measurements of urine volume

Urine output measurement is one of the easiest tests to help diagnose renal failure. Due to a blockage, low urine flow may be a sign of kidney disease. An underlying pathology or injury may be the obstruction’s source.

  1. Hematologic examinations

In order to ascertain the presence and concentration of certain compounds in your urine, your doctor may ask you to take a blood sample. The kidneys filter substances such as blood urea nitrogen and creatinine. The various ratios of these substances can reveal details about your health and kidney function. A sudden rise in these substances could indicate acute renal failure.

Among these tests are:

Creatinine: Particularly, creatinine, a substance produced by your muscles, can be used to diagnose kidney failure because a healthy kidney would eliminate creatinine from the blood and eliminate it through urine.

Blood urea nitrogen (BUN): Your blood also contains urea, another waste substance. When broken down, protein is what creates it. The kidneys also eliminate it from your blood. Urea nitrogen can be measured in blood samples.

Electrolytes: Elements like potassium and sodium help your body maintain the proper balance of fluids. Since your body can’t eliminate the appropriate quantity of sodium, a high sodium level may be a sign that your kidneys aren’t working well.

  1. The rate of glomerular filtration (GFR)

This test measures the kidneys’ overall function. It calculates the volume of blood that flows through the glomeruli in a minute. The kidneys’ microscopic filters, called glomeruli, remove waste from the blood.

Your blood creatinine level is one of the numerous criteria that the lab specialist uses to assess your GFR. Different formulas are served to adults and youngsters. included in the formula:

  • Age
  • measurement of blood creatinine
  • Race and ethnicity
  • Sexual
  • Height
  • Mass

The creatinine clearance test, which can also be used to assess kidney function, requires a 24-hour urine sample.

There may be modest variations in the usual value ranges amongst laboratories. Different labs test different metrics or samples. Talk to your doctor about the relevance of the test results that pertain to you.

Levels below 60 mL/min/1.73 m2 for three months or more are indicative of chronic renal dysfunction. You should consult a physician right immediately if your GFR is less than 15 mL/min/1.73 m2, as this could indicate renal failure.

  1. Visualization

At different phases of an illness, several imaging modalities, including MRI, ultrasound, and CT scan, may be recommended based on your symptoms and indicators. Your doctor can find obstructions or other issues that may be impacting your kidneys and urinary tract with the aid of these imaging procedures.

  1. Autopsy

To get a tiny sample of the kidney tissue, a renal tissue biopsy is advised. This examination aids in the detection of any deposits, infectious organisms, or scarring.

Complications caused by kidney failure

The following are some of the issues that might result from renal failure:

1. Weakening of the bones and muscles

Bone weakening might be one of the difficulties caused by the disturbance of minerals like calcium and phosphorus caused by renal failure. An imbalance in your electrolyte levels can also lead to muscle weakness, which can result in irregular heartbeats or even paralysis.

2.  Uremia

Kidney failure is a result of the body accumulating nitrogenous waste products. Higher dosages may cause mental abnormalities and problems with bleeding.

3.  Anemia

Renal failure may lead to anemia, a condition marked by a low red blood cell count. The main cause of anemia in kidney failure is believed to be inadequate amounts of erythropoietin, a hormone generated by the kidneys that aids in the synthesis of red blood cells. However, other variables contribute to anemia as well.

4.  Retention of fluids

The task of eliminating excess water and toxins from your blood falls to your kidneys. You may be more likely to retain fluid in the event of renal failure, which could result in lower limb swelling.

5.  Heart Disease

Heart issues can result from renal failure. Dialysis patients most frequently die from heart diseases. Chest pain may be brought on by inflammation of the heart’s lining.

6.  Acidosis metabolism

Excess blood acid due to renal failure can result in nausea, vomiting, dyspnea, and apprehension. Additionally, it may result in bone disorders and kidney stones.

7.  Imbalance of electrolytes

The impaired kidney’s capacity to control electrolyte imbalance is restricted. Two significant abnormalities associated with kidney failure are hyperkalemia (high concentration of potassium in the blood) and hyponatremia (low amounts of sodium in the blood).

8.  Problems related to cardiac function

Arrhythmias, or irregular heartbeats, pericarditis, or inflammation of the heart membrane, and pericardial effusion, or accumulation of fluid in the pericardium, are the main cardiac problems. Furthermore, uremia and fluid overload can cause direct cardiac damage as well as compromised heart function.

9.  Lack of food

Long-term renal disease patients are more likely to have malnutrition, which is characterized by low protein and energy fuel stores in the body as well as deficits in certain micronutrients.

10. The Calciphylaxis

It’s a rare and dangerous ailment that primarily affects those with advanced chronic kidney disease. The deposition of calcium in the skin’s and fatty tissues’ tiny blood vessels is what defines it.

11. Additional Complications

  • Some individuals may experience secondary issues like:
  • accumulating fluid in the lungs
  • Injury to the nerves
  • Depression
  • Failure of the liver
  • Gout (higher uric acid levels)
  • Infections of the skin
  • Diabetic kidney disease

Prevention Of Kidney Failure

Modifying your lifestyle to a healthier one can lower your chance of kidney failure. Make careful to read the prescription label and adhere to the suggested dosage guidelines while taking over-the-counter medications, such as acetaminophen, aspirin, ibuprofen, or other non-steroidal anti-inflammatory drugs. If you use these drugs in excess, you run the risk of developing renal failure. Consult your physician and heed their recommendations on how to treat your illness. Your chance of having renal failure can be significantly decreased by maintaining a healthy diet and refraining from alcohol.

Specialist To Visit

  • General physician
  • Nephrologist
  • Urologist

Treatment Of Kidney Failure

Renal failure treatment typically necessitates hospitalization. Patients with renal failure are typically brought to the hospital due to an underlying pathology or a pre-existing medical condition. How long you stay will depend on the severity of your condition and the reason for your renal failure. When to release you will be decided by your doctor based on how rapidly your kidneys are mending. You may be able to recuperate at home in specific circumstances.

Treatment (The cause of Chronic Kidney Debases)

Diagnosing and treating the underlying cause of kidney failure might aid in managing the condition if it has been brought on by an infection or injury to your kidneys. The cause and severity of the ailment will determine your therapy options.

 1. Therapy intended to bring the body’s fluid levels into equilibrium

A deficiency of fluids in the blood could be the cause of your renal failure. Intravenous fluids would be necessary for this. Renal failure, which typically results in fluid retention and swelling of the lower extremities, including the legs and ankles, can occasionally be caused by consuming too much fluid. In certain situations, a doctor may prescribe diuretics, which aid the body in eliminating excess fluid. Patients who do not react to diuretics may need to undergo ultrafiltration.

2.  Drugs for blood potassium regulation

One salt that aids in controlling essential bodily processes is potassium. An irregular heartbeat brought on by high potassium levels might result in serious problems and exhaustion of the muscles. If your kidneys are not able to eliminate potassium from your blood, your doctor may suggest that you take calcium, glucose with insulin, sodium polystyrene sulfonate, or both. This will stop the potassium levels in your blood from increasing.

Medication to control the levels of calcium, Your doctor can suggest a calcium infusion if your calcium levels start to decline to avoid issues.

3.  Dialysis

Through the use of a machine, the toxins in your blood are filtered and purified throughout this operation. The machine essentially takes over the roles that your kidneys would normally play. Your doctor may ask you to use a portable catheter bag or attach you to a large machine for dialysis, depending on the type of treatment.

Two varieties of dialysis exist:

  • Hemodialysis: To get hemodialysis, a catheter, or tube, will be placed into a vein in your neck or legs. Your blood will be routinely cleaned by the machine. It is advised that hemodialysis patients visit a hospital or dialysis facility three or four times per week for treatment.
  • Peritoneal dialysis: A catheter and dialysis fluid are used in this type of dialysis to purify the blood. A tube that removes extra fluid, salt, and potassium is put into your abdomen. An automated exchanger can remove this fluid from your body as you sleep. It is advised that children with renal failure receive peritoneal dialysis.

4.  Transplantation of kidneys

A kidney from a healthy donor is surgically implanted into the patient during a kidney transplant to replace the damaged kidney. It is recommended that patients with end-stage renal disease proceed with a kidney transplant as it is their best course of treatment.

Typically, the search for a live donor is quicker. Finding a donor kidney that fits the patient’s body is usually a lengthy process. Immunosuppressive medications may need to be taken by the surgical patient for a while following the procedure to keep the body from rejecting the new kidney.

5.  Home-care For Kidney Failure

Renal failure requires close observation and care. Here are some guidelines to adhere to at home: Make sure you take your prescription drugs on time if you have been given them to treat your medical condition. Eat a balanced diet and cut foods that damage your kidneys.

Alternative Treatments for Dialysis

Ayurvedic Remedies for Chronic Kidney Failure:

Ayurvedic Herbs

Ayurvedic Herbs

In Ayurveda of kidney failure treatment several herbs are particularly useful in rejuvenating the kidneys by restoring their filtration capacity and enhancing their general functioning. With this course of therapy, the chance of renal failure and the requirement for dialysis can be completely avoided. You can view some of the most significant Ayurveda treatments.

Supporting the damaged renal cells and regenerating the kidney’s nephrons herbal combinations that can be used to treat kidney disease.


Maintaining a healthy lifestyle and engaging in regular, low-impact exercise, like walking, can assist in managing your kidney disease. Consult your physician about the best kind of exercise for your particular situation.

Dietary Adjustments

Pick a diet low in sodium and abide by your doctor’s recommendations about protein. Depending on your stage of renal failure, there will be different dietary restrictions. Since your food affects the health of your kidneys, you must heed the recommendations of your physician.


Choosing easy workouts like yoga will assist you in reducing stress and anxiety, which can further improve the health of your kidneys.
