Kidney Failure: Complete Guide to Diagnosis, Treatment, and Prevention

The global prevalence of chronic kidney disease has increased significantly. Estimates show that about 10-15% of people worldwide have some degree of kidney dysfunction. This rate is higher in low- and middle-income countries because access to health services and preventive care is more limited.

The prevalence of kidney failure varies across regions of the world. In developed countries such as the United States and Europe, prevalence appears higher because diagnosis and reporting are better.

At the same time, kidney failure is also common in developing countries, but the numbers are often underreported because access to medical care is limited.

In recent decades, the prevalence of kidney failure has risen because risk factors such as diabetes and obesity have become more common.

Another reason for the increase in reported kidney failure is better diagnosis and disease management.

Kidney failure is a serious and complex condition whose symptoms may appear gradually over time.

These symptoms vary depending on the stage of disease and the type of kidney failure, whether acute or chronic. Below, we review kidney failure symptoms in different groups in detail.

Types of Kidney Failure

Kidney failure is divided into two types: acute and chronic.
Acute kidney failure is a sudden disorder that occurs over a short period of time and is often caused by reduced blood flow to the kidneys, direct injury to kidney tissue, or blockage in the urinary drainage system.

This type of failure is usually reversible with appropriate treatment, but without care it can lead to serious complications and even death.

By contrast, chronic kidney failure develops gradually over months or years and is usually the result of underlying conditions such as diabetes, high blood pressure, or chronic kidney diseases. In this condition, kidney function declines over time and may reach a stage where dialysis or kidney transplantation is needed.

Acute Kidney Injury (AKI)

Acute kidney failure occurs when kidney function suddenly declines rapidly, within hours to a few days. Several causes can lead to this type of kidney failure.

Causes of Acute Kidney Injury

1. Pre-renal (Pre-renal)

Reduced blood flow to the kidneys due to factors such as severe loss of blood volume, for example from bleeding or dehydration, shock, heart failure, or blockage of the renal arteries can cause acute kidney injury.

1. Renal (Renal)

Direct damage to kidney tissue due to severe infections such as glomerulonephritis, toxins, certain medications such as some antibiotics and nonsteroidal anti-inflammatory drugs, or autoimmune diseases can lead to acute kidney injury.

1. Post-renal (Post-renal)

Blockage of the urinary outflow tract, for example because of a kidney stone, tumor, or enlarged prostate, can cause urine to build up in the kidneys and lead to acute kidney injury.

Chronic Kidney Disease (CKD)

Chronic kidney failure occurs when kidney function declines gradually and progressively over months to years. This type of failure can progress to end-stage disease, where the kidneys completely lose their function and dialysis or kidney transplantation becomes necessary.

Causes of Chronic Kidney Disease

1. Diabetes

Diabetes is the most common cause of chronic kidney disease. It can damage the small blood vessels in the kidneys.

1. High blood pressure

High blood pressure can damage the kidney blood vessels and cause chronic kidney disease.

1. Glomerulonephritis

Inflammation of the glomeruli, the small filtering units in the kidneys.

1. Polycystic kidney disease

An inherited disease that causes multiple cysts to form in the kidneys.

1. Recurrent urinary tract infections

Repeated and severe infections can damage kidney tissue.

1. Long-term use of certain medications

Long-term use of medications such as NSAIDs can lead to kidney failure.

General Symptoms of Kidney Failure

Symptoms of kidney failure indicate a serious disruption in the function of this vital organ.

The kidneys filter the blood, remove waste products, and regulate fluid and electrolyte balance in the body.

When kidney function declines, toxins and excess fluid accumulate in the body, and this can negatively affect multiple body systems.
Symptoms in this disease usually develop gradually, and noticing them early plays a vital role in preventing disease progression and more serious complications.

General symptoms of kidney failure usually include the following:

1. Fatigue and general weakness
One of the main signs of kidney failure is severe fatigue and weakness. This occurs because toxins build up in the body as kidney efficiency declines. In addition, reduced production of erythropoietin by the kidneys can lead to anemia. Anemia worsens weakness and fatigue because less oxygen reaches the tissues.

2. Swelling (edema)
Fluid accumulation in the body is one direct result of poor kidney function. This buildup appears as swelling or puffiness in the legs, ankles, and around the eyes. Edema may cause discomfort and limited movement and indicates fluid imbalance in the body.

3. Changes in urination pattern
Kidney failure can change the pattern of urination. These changes include unusually decreased or increased urine volume, darker urine, and foamy urine, which can indicate abnormal protein loss. In more advanced cases, blood in the urine may also appear and usually suggests serious kidney damage or infection.

Symptoms of Acute Kidney Injury (AKI)

Acute kidney injury is a serious medical condition defined by a sudden and severe reduction in kidney function. It can progress quickly and cause toxins and waste products to accumulate in the body. Unlike chronic kidney disease, AKI symptoms usually appear suddenly and require rapid diagnosis and urgent treatment.
Recognizing the symptoms of this condition can help prevent more serious complications, such as permanent kidney damage or injury to other vital organs.

Common symptoms of acute kidney injury include:

1. Sudden decrease in urine volume
One of the first and clearest symptoms of acute kidney injury is a severe and sudden drop in urine output. This may happen because of reduced blood flow to the kidneys, urinary tract obstruction, or damage to kidney tissue. In this situation, inadequate urine excretion can quickly lead to fluid and toxin buildup in the body.

2. Nausea and vomiting
Rapid accumulation of toxins and waste products in the blood, caused by impaired blood filtration by the kidneys, can affect the digestive system. This often leads to severe nausea and vomiting, which may be accompanied by weakness and loss of appetite.

3. Pain in the flank or lower back
Severe pain in the flank or lower back is another symptom of acute kidney injury. This pain may be caused by urinary tract obstruction, such as a kidney stone, or by infection. Flank or back pain usually appears suddenly and severely and may occur with other symptoms.

4. Reduced alertness and confusion
Brain dysfunction caused by rising toxin levels in the blood is another common symptom of acute kidney injury. It can cause confusion, severe drowsiness, and even reduced level of consciousness. In more advanced cases, the patient may develop mental status changes or difficulty concentrating, which indicates a medical emergency.

Symptoms of Chronic Kidney Disease (CKD)

Chronic kidney disease is a progressive condition that gradually reduces kidney function.
In the early stages, it may have no obvious symptoms, but as it progresses, multiple symptoms can appear throughout the body, often because waste products accumulate and fluid and electrolyte balance is disturbed.
Recognizing these symptoms is important because early management can prevent disease progression and more serious complications.

Common Symptoms of Chronic Kidney Disease

1. Itchy skin
One common symptom of chronic kidney disease is persistent, bothersome itching. This itching occurs because waste products such as phosphorus accumulate in the blood. It is usually more severe in patients with advanced disease and can seriously affect quality of life.

2. Muscle spasms
Disruption in electrolytes such as calcium and potassium in chronic kidney disease can cause muscle cramps and spasms. This problem often occurs suddenly and can be painful and disabling.

3. Shortness of breath
Reduced kidney function may cause excess fluid to accumulate in the body, including in the lungs. This condition, known as pulmonary edema, can cause shortness of breath, especially during physical activity or even at rest.

4. Metallic taste in the mouth and bad breath
Toxin buildup in the blood due to poor kidney function can affect a person's sense of taste and create a metallic taste in the mouth. These toxins may also cause bad breath, which is often distressing for the person and those around them.

5. High blood pressure
Chronic kidney disease is often associated with high blood pressure. Damaged kidneys cannot properly remove excess fluid, which increases pressure inside the blood vessels. At the same time, high blood pressure itself is one of the main factors that worsens kidney damage and disease progression.

Symptoms of Kidney Failure in Children

Kidney failure in children is a serious condition that can significantly affect growth and development. Unlike adults, symptoms in children may be less obvious and may appear as subtle changes in growth, behavior, or developmental abilities. Early recognition and treatment of kidney failure in children can play a key role in improving quality of life and preventing long-term complications.

Common symptoms of kidney failure in children

1. Poor growth
Children with kidney failure often face growth problems. Metabolic disturbances and nutritional problems related to kidney failure, such as insufficient calories or protein, can limit a child's physical growth. These children often do not reach the height and weight expected for their age.

2. Irritability and restlessness
Changes in electrolyte status, such as increased potassium or phosphorus levels, and toxin buildup in the blood can cause restlessness and irritability in children. These changes may negatively affect sleep, appetite, and daily behavior.

3. Delayed development of motor and language skills
Kidney failure can affect the development of the nervous system in children and cause delays in motor skills, such as sitting or walking, and language skills. These delays may result from deficiencies in essential nutrients, metabolic disturbances, or the direct effects of toxins on the brain. However, kidney transplantation in children can produce catch-up growth and help correct this problem.

Diagnosis of Kidney Failure

Diagnosing kidney failure is a complex, multi-step process that uses different methods to evaluate kidney function and detect abnormalities.

The following are the different methods used to diagnose kidney failure:

Medical history review and physical examination

A careful review of the patient's medical history, including family history, medications, and other chronic conditions such as diabetes and high blood pressure, can help the physician diagnose kidney failure. Physical examination also includes assessment of clinical signs such as high blood pressure, swelling, and signs of kidney failure.

Blood tests

• Serum creatinine

Creatinine is a waste product produced by creatine metabolism in the muscles and is normally eliminated by the kidneys. A rise in blood creatinine indicates that the kidneys are not excreting it adequately and that kidney function has declined.

• Glomerular filtration rate (GFR)

GFR is a measure of how well the kidneys filter the blood. A lower GFR indicates reduced kidney function. This value is usually calculated using formulas based on serum creatinine level, age, sex, and race.

• Blood urea nitrogen (BUN)

Blood urea nitrogen is another marker of kidney function. Elevated BUN can indicate kidney failure or other conditions that reduce blood flow to the kidneys.

Urine tests

• Urinalysis

This test examines urine contents, including protein, white and red blood cells, glucose, and other waste products. Protein or blood in the urine can be a sign of kidney damage.

• Urine albumin-to-creatinine ratio (UACR)

This test measures albumin, a type of protein, in relation to creatinine in the urine. An elevated ratio can indicate kidney damage.

• Creatinine clearance test

This test measures how much creatinine is excreted in the urine over a 24-hour period and helps determine how well the kidneys clear creatinine.

Imaging

• Ultrasound

Ultrasound uses sound waves to create images of the kidneys and assess their size, shape, and structure. This method can help identify obstructions, cysts, tumors, and other changes in the kidneys.

• CT scan

This method combines multiple X-ray images to create detailed cross-sectional images of the kidney.

A CT scan can help identify kidney stones, tumors, and other structural abnormalities.

• MRI

MRI uses magnetic fields and radio waves to create detailed images of the kidneys and surrounding tissues. It is useful for evaluating tumors and other complex abnormalities.

Kidney biopsy

In some cases, a kidney biopsy is performed for a more precise diagnosis and to assess the degree of kidney damage. This procedure involves removing a small sample of kidney tissue with a thin needle and examining it under a microscope.

Specialized tests

• Genetic tests

When kidney failure is suspected to result from inherited diseases such as polycystic kidney disease, genetic testing can help with diagnosis.

• Immunologic tests

These tests look for antibodies or other signs of autoimmune diseases that can cause kidney failure.

Risk Factors for Kidney Failure

Kidney failure, or chronic kidney disease (CKD), gradually reduces kidney function and can lead to complete kidney failure. In this condition, the kidneys cannot filter waste products and excess fluid from the blood, which can ultimately cause serious problems for the patient. Understanding the risk factors for this disease can help with prevention and more effective treatment.

Diabetes

Type 1 and type 2 diabetes are among the most important risk factors for kidney failure. Chronically high blood sugar can damage the small blood vessels in the kidneys, a process called diabetic nephropathy.

This damage gradually reduces kidney function.

High blood pressure

High blood pressure, or hypertension, damages the small blood vessels of the kidneys and reduces their ability to filter blood. For this reason, blood pressure control is essential for preventing kidney failure.

Cardiovascular diseases

Cardiovascular diseases such as heart failure and coronary artery disease can increase the risk of kidney failure. Heart problems can reduce blood flow to the kidneys and impair their function.

Obesity and a sedentary lifestyle

Obesity and physical inactivity increase the risk of chronic diseases such as diabetes and high blood pressure, and therefore are important risk factors for kidney failure. Weight loss and regular physical activity can help lower this risk.

Long-term use of certain medications

Frequent, long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen and naproxen can reduce kidney function and lead to kidney failure by directly damaging kidney tissue or reducing blood flow to the kidneys.

Age and demographic factors

Older age is also a risk factor for kidney failure. As people age, kidney function naturally declines. For this reason, kidney failure in older adults is more common than in younger people. In addition, some ethnic and racial groups, such as African Americans and Hispanic people, are at higher risk of this disease.

Genetic factors

Genetic factors play an important role in kidney failure. A family history of kidney failure or related diseases can increase the risk. Some genes also make a person more susceptible to kidney failure. For example, polycystic kidney disease (PKD) is an inherited disease associated with multiple cysts in the kidneys and can lead to kidney failure.

In this disease, defective genes directly affect kidney function.

Stages of Kidney Failure

Kidney failure, or chronic kidney disease (CKD), refers to gradual and progressive loss of kidney function. The disease is divided into five stages, classified by glomerular filtration rate (GFR).

GFR measures how well the kidneys filter the blood, and a lower GFR indicates reduced kidney function. Here we review the stages of kidney failure in a comprehensive, scientific way.

Stage 1: Kidney damage with normal or increased GFR

• GFR ≥ 90 ml/min/1.73 m²

• At this stage, despite kidney damage, kidney function is still normal or increased. Patients may have no symptoms, and damage may be detected only through blood tests or imaging.

• At this stage of kidney failure, careful control of diabetes and blood pressure, avoidance of kidney-harming medications, and lifestyle changes such as healthy eating and regular exercise can be very helpful.

Stage 2: Kidney damage with mildly reduced GFR

• GFR 60-89 ml/min/1.73 m²

• At this stage, GFR is mildly reduced, and kidney damage may be detected through blood tests, urine tests, or imaging.

• In addition to stage 1 measures, nutritional counseling and regular medical follow-up may be needed.

Stage 3: Moderately reduced GFR

• GFR 30-59 ml/min/1.73 m²

• At this stage, a moderate reduction in GFR is seen, and patients may experience mild to moderate symptoms such as fatigue, swelling, and changes in urination.

• To manage this stage, blood pressure and diabetes must be controlled more carefully. Kidney-protective medications such as ACE inhibitors and ARBs can help. Nutritional supplements may be used to manage anemia and electrolyte problems that develop at this stage.

Stage 4: Severely reduced GFR

• GFR 15-29 ml/min/1.73 m²

• At this stage, GFR is severely reduced. The patient will experience kidney failure symptoms more often and more severely, including severe fatigue, swelling, reduced appetite, and difficulty concentrating.

• To manage this stage, the patient should be prepared for kidney replacement therapies such as dialysis or kidney transplantation. Specialist care and consultation with a multidisciplinary medical team are also needed for comprehensive management.

Stage 5: End-stage kidney failure

• GFR < 15 ml/min/1.73 m²

• When a patient's GFR falls below 15, the kidneys have almost completely lost their function and can no longer filter waste products and excess fluid. At this stage, the patient needs kidney replacement therapy such as dialysis or kidney transplantation. Symptoms at this stage can include severe fatigue, fluid retention, severe anemia, heart and breathing problems, and major changes in urination.

• Regular dialysis, either hemodialysis or peritoneal dialysis, or kidney transplantation is necessary to manage this stage. Supportive care and symptom management are also very important.

Treatment Methods for Each Stage of Chronic Kidney Disease

Chronic kidney disease (CKD) is divided into five stages, and each stage requires its own treatment and management methods. Appropriate treatment at each stage can slow disease progression and improve patients' quality of life. Here we review the treatment methods for each stage of kidney failure in a comprehensive, scientific way.

Treatment of stage 1 kidney damage with normal or increased GFR

• Diagnosis and assessment

At this stage, the kidneys still function normally, but damage is present and may be detected through blood tests, urine tests, or imaging.

• Lifestyle changes

Healthy eating, reduced salt intake, weight control, and regular physical activity are recommended.

• Control of chronic diseases

Careful management of diabetes and blood pressure with appropriate medications and regular medical follow-up.

• Prevention of further damage

Avoiding medications that can harm the kidneys, such as some nonsteroidal anti-inflammatory drugs (NSAIDs).

Treatment of stage 2 kidney damage with mildly reduced GFR

• Assessment and follow-up

Regular monitoring of kidney status through periodic tests.

• Nutritional counseling

A low-protein, low-phosphorus diet to reduce the burden on the kidneys.

• Medication therapy

• Use of ACE inhibitors or ARBs to control blood pressure and reduce proteinuria, meaning protein loss in the urine.

Treatment of stage 3 kidney damage with moderately reduced GFR

• Management of chronic diseases

Tighter control of diabetes and blood pressure and use of additional or stronger medications to control disease as effectively as possible.

• Kidney-protective medications

Use of medications such as ACE inhibitors and ARBs to reduce proteinuria and protect the kidneys.

• Nutritional supplements

Use of iron and vitamin D supplements to manage anemia and bone problems.

• Fluid and electrolyte control

Limiting salt and fluid intake to prevent fluid retention and manage potassium and phosphorus levels in the blood.

Treatment of stage 4 kidney damage with severely reduced GFR

• Preparation for replacement therapies

Patient education and preparation for dialysis or kidney transplantation.

• Specialist care

Consultation with a multidisciplinary team, including a nephrologist, dietitian, and psychologist.

• Management of symptoms and complications

Treatment of anemia with erythropoietin, management of metabolic acidosis with bicarbonate, and closer control of electrolyte levels.

• Regular monitoring

Regular follow-up with blood and urine tests to assess disease progression and adjust treatments.

Treatment of stage 5 kidney damage and end-stage kidney failure

• Kidney replacement therapy

Performing dialysis (hemodialysis or peritoneal dialysis) to filter the blood in place of nonfunctioning kidneys.

• Hemodialysis

A process in which blood is filtered through an external filter. This method is usually performed three times a week at dialysis centers.

• Peritoneal dialysis

Using the peritoneal membrane in the abdomen as a filter to clean the blood. This method is usually done at home, and the patient can perform it several times during the day or overnight.

• Kidney transplantation

If the patient is eligible, kidney transplantation can improve quality of life and eliminate the need for dialysis. Kidney transplantation requires lifelong use of immunosuppressive medications.

• Management of symptoms and complications

Supportive care to manage symptoms of kidney failure such as fatigue, anemia, fluid retention, and heart problems.

• Psychological and social support

Providing psychological and social support to patients and their families to cope with the challenges of end-stage kidney failure and replacement therapies.

Prevention and Reducing Recurrence of Kidney Failure

Preventing kidney failure and reducing recurrence require a multifaceted approach that includes lifestyle changes, control of chronic diseases, medication therapy, regular medical follow-up, and avoidance of kidney-damaging factors.

By following these methods and monitoring kidney health, patients can improve quality of life and reduce the risk of recurrent kidney failure. Patients should stay in regular contact with their physician and follow an appropriate treatment plan.

Lifestyle changes

• Healthy nutrition

A balanced diet with an appropriate amount of protein and low levels of salt, fat, and phosphorus. Increased intake of fruits, vegetables, and whole grains is also recommended.

• Weight control

Maintaining a healthy weight through a healthy diet and regular physical activity. Obesity increases the risk of kidney failure by adding extra strain on the kidneys and raising the likelihood of diseases such as diabetes and high blood pressure.

• Physical activity

Regular physical activity, at least 30 minutes a day, five days a week, can help improve heart health and lower blood pressure.

Control of chronic diseases

• Diabetes

Careful diabetes management and blood sugar control through diet, physical activity, and medications should be followed closely. Insulin or oral antidiabetic medications should be used under a physician's supervision.

• High blood pressure

Blood pressure can be controlled with prescribed medications such as ACE inhibitors, angiotensin II receptor blockers (ARBs), and diuretics. Regular blood pressure monitoring and adherence to a low-salt diet are important.

• Cardiovascular diseases

Cardiovascular diseases can be prevented and managed through appropriate medications, healthy eating, and regular physical activity.

Medication treatment

• ACE and ARB inhibitors

These medications can help reduce proteinuria, meaning protein loss in the urine, and protect the kidneys.

• Control of blood lipid levels

Using statins to control cholesterol levels and prevent cardiovascular diseases that can affect kidney health can be very helpful.

• Phosphorus-lowering medications and calcium supplements Because their kidneys are not working properly, patients with kidney failure may develop electrolyte imbalances, including calcium and phosphorus imbalance. Therefore, managing phosphorus and calcium levels is important to prevent bone problems and other complications related to electrolyte disorders.

Vaccination

• Influenza vaccination

Annual influenza vaccination is very important for patients with kidney failure or those at risk because they have a higher risk of respiratory infections.

• Pneumococcal vaccination

The pneumococcal vaccine (PPSV23) is recommended for people with kidney failure to prevent serious infections such as pneumonia and meningitis.

• Hepatitis vaccination B

Patients with kidney failure, especially those receiving dialysis, are at high risk of hepatitis B virus infection. Hepatitis B vaccination is very important for these patients.

• COVID-19 vaccination

COVID-19 vaccines are recommended for kidney patients to reduce the risk of infection and severe complications from the disease.

Regular medical follow-up

• Periodic tests

Regular blood and urine tests to assess kidney function, electrolyte levels, blood sugar, and blood pressure. These tests help detect problems early and adjust the treatment plan.

• Regular medical examinations

Regular visits with a nephrologist, a kidney specialist, to assess kidney status and update the treatment plan.

• Control of symptoms and complications

Monitoring disease symptoms and managing complications such as anemia, bone problems, and electrolyte disturbances.

Avoiding factors that damage the kidneys

• Use of kidney-harming medications

Avoiding long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen and naproxen unless supervised by a physician.

• Alcohol and tobacco use

Reducing or stopping alcohol and tobacco use, which can damage blood vessels and affect kidney health.

Psychological and social support

• Psychological support

Receiving psychological support from family, friends, and counselors to manage stress and concerns related to the disease.

• Education and awareness

Increasing patients' awareness of kidney failure, prevention methods, and management through ongoing education and participation in support groups.

Outlook and Prognosis

The prognosis of kidney failure, whether acute or chronic, depends strongly on the disease stage and the management of factors that affect it. Early diagnosis, appropriate medical care, and lifestyle changes can significantly improve patients' quality of life and increase survival. Cooperation among the patient, family, and medical team is essential for successful disease management.

Outlook and prognosis of acute kidney injury (AKI)

1. Causes and speed of progression:

   • Acute kidney injury occurs rapidly and usually in response to a trigger such as severe infection, loss of blood volume, use of kidney-toxic medications, or urinary tract obstruction. The prognosis of AKI depends on the underlying cause and the severity of injury. If the trigger is identified and treated promptly, many patients recover completely.

2. Treatment and management:

   • With rapid and appropriate treatment, including correction of fluid status, use of appropriate medications, and temporary dialysis if needed, kidney function can return to normal. In more severe cases, there is a risk of progression to chronic kidney disease, and prognosis then depends on long-term management.

Outlook and prognosis of chronic kidney disease (CKD)

1. Stages 1 and 2: Mild to moderate disease

   • At these stages, kidney function is nearly normal. With appropriate management of risk factors such as diabetes and high blood pressure, disease progression can be prevented. Prognosis at these stages is usually good, and many patients can live a normal life.

2. Stage 3: Moderate disease

   • At this stage, a greater decline in kidney function is seen, and patients may experience symptoms such as fatigue and edema. With careful management, many patients can live without needing dialysis or kidney transplantation, although there is a risk of progression to higher stages.

3. Stage 4: Severe disease

   • A more severe decline in kidney function is present, and the patient needs preparation for advanced treatments such as dialysis or kidney transplantation. Prognosis depends strongly on the patient's response to treatment. Proper management can improve quality of life and extend survival.

4. Stage 5: End-stage kidney failure

   • This stage is known as end-stage kidney failure, and the patient urgently needs dialysis or kidney transplantation. Without these treatments, survival declines significantly. Prognosis at this stage depends on several factors, including the patient's age, overall health, and access to advanced treatments. Successful kidney transplantation can provide a much better outlook.

Factors Affecting the Overall Outlook and Prognosis of Kidney Failure

• Control of risk factors

Control of diabetes, high blood pressure, and other underlying conditions can significantly slow disease progression and improve prognosis.

• Regular medical care

Continuous monitoring of kidney function and adjustment of treatments based on changes in the patient's condition are essential.

• Lifestyle

Dietary changes, regular exercise, and quitting smoking can help improve the patient's overall condition and slow disease progression.

• New treatments

Research into new and innovative treatments may improve the prognosis of patients with kidney failure in the future.

Summary

Kidney failure is a serious disease that can occur for many reasons, including diabetes, high blood pressure, glomerulonephritis, and long-term use of certain medications. It can be acute or chronic, and each form has its own symptoms and treatment methods. Chronic kidney disease is commonly staged from early kidney damage with few or no symptoms through advanced loss of kidney function, where dialysis or kidney transplantation may be required.

Symptoms of kidney failure include fatigue, nausea, loss of appetite, swelling of the limbs, changes in urination, and flank pain.

For accurate diagnosis, blood and urine tests, ultrasound, CT scan, and MRI may be performed.

Treatment of kidney failure depends on the disease stage and may include dietary changes, medications, dialysis, and, in advanced cases, kidney transplantation.

Prevention of kidney failure includes controlling diabetes and blood pressure, maintaining a healthy lifestyle, avoiding harmful medications, and drinking enough water.

In addition to medical treatments, certain lifestyle changes and medications used with medical advice can help improve kidney function.

Understanding the symptoms, stages, and treatment methods of kidney failure is very important for managing and preventing this disease.

With regular testing, lifestyle changes, and consultation with a physician, patients with kidney failure can improve their quality of life and help prevent disease progression.

Awareness of appropriate treatment methods and management of risk factors can reduce the burden of disease and improve overall community health.
