Kidney health plays an important role in maintaining the stability of the body. When the kidneys have problems, other physiological functions will inevitably be affected. Kidney failure, whether acute or chronic, is becoming an increasingly global concern.
With a serious impact on the quality of life, awareness of the causes, symptoms, and treatments of kidney failure is necessary. Understanding this disease will help individuals take the initiative in preventing and protecting healthy kidneys.
Kidney failure occurs when the kidneys can no longer filter waste.
Types of Kidney Failure
Kidney failure is a serious loss of kidney function, making it difficult for the body to filter and remove waste and maintain fluid and electrolyte balance. Classification of kidney failure helps determine the extent of kidney damage and the appropriate treatment options. Kidney failure can be divided into two main types: acute kidney failure and chronic kidney failure, each with its unique characteristics and challenges.
Acute kidney failure (AKI)
Acute kidney failure is a sudden loss of kidney function over a short period, which can range from a few hours to a few days. The main causes include dehydration, infection, or side effects of medications. Although it can be completely reversible with prompt treatment, if left untreated, it can lead to serious complications and even death. Typical signs of AKI include decreased urination, edema, and increased creatinine levels in the blood.
Chronic Kidney Failure (CKD)
In contrast to AKI, chronic kidney failure occurs slowly and progresses over time, often due to underlying conditions such as diabetes and high blood pressure. CKD leads to permanent kidney damage, affecting the kidneys’ ability to filter and remove toxins. If left unchecked, the disease can progress to end-stage kidney failure, requiring treatment such as dialysis or a kidney transplant. Symptoms of CKD include fatigue, loss of appetite, and shortness of breath.
Each type of kidney failure requires a different treatment and management strategy, depending on the cause and extent of kidney damage.
Causes and Risk Factors of Kidney Failure
Kidney failure, whether acute or chronic, is a disease that can have serious consequences for health and quality of life. Understanding the causes and risk factors helps detect the disease early and manage it effectively. Each risk factor contributes to the development of kidney failure, increasing the likelihood of kidney damage and worsening the condition.
Causes of Kidney Failure
Kidney failure can come from many different sources. In acute kidney failure, common causes include dehydration due to diarrhea or vomiting, serious infections, or side effects of certain medications, such as nonsteroidal anti-inflammatory drugs. Meanwhile, chronic kidney failure is often associated with long-term underlying conditions such as diabetes and high blood pressure, which damage the small blood vessels in the kidneys, leading to a gradual decline in kidney function.
Risk Factors
Many factors can increase the risk of kidney failure. A sedentary lifestyle, unhealthy diet, and smoking are significant risk factors that increase the stress on the kidneys over time. In addition, advanced age, a family history of kidney disease, and conditions such as cardiovascular disease or lipid disorders also contribute to an increased risk of kidney failure. In addition, people with autoimmune diseases such as lupus or glomerulonephritis are also more susceptible to severe kidney damage.
These factors interact with each other, creating a dangerous "trap" that makes the kidneys vulnerable to damage and leads to irreversible kidney failure if not treated promptly.
Symptoms of Kidney Failure
Kidney failure, whether acute or chronic, may not cause obvious symptoms at first. However, as kidney function declines, symptoms become more noticeable and can seriously impact health. Early recognition of these signs is crucial to prevent dangerous complications.
Early Symptoms of Kidney Failure
In the early stages, kidney failure can cause vague symptoms that can be easily confused with other health problems. Fatigue and weakness are common signs, along with decreased urine output and swelling in the legs or ankles. Patients may experience loss of appetite and nausea, which can reduce their eating ability and cause a decline in overall health.
Progressive and Severe Symptoms
As kidney failure progresses, symptoms become more severe. Patients may have difficulty breathing due to fluid buildup in the lungs, experience chest pain, or have trouble concentrating. They may also experience muscle cramps, mood swings, and memory loss. In the final stages, kidney failure can cause loss of consciousness and dangerous cardiovascular problems. This requires immediate medical intervention to minimize permanent damage.
Early recognition and treatment of these symptoms are vital in preventing the progression of kidney failure and preserving long-term kidney function.
Diagnosis of kidney failure
Diagnosis of kidney failure is a complex process, requiring a combination of clinical tests, paraclinical tests, and a comprehensive assessment of the patient's health status. Early detection of kidney failure not only helps control the disease effectively but also reduces the risk of serious complications, even death.
Blood and urine tests
One of the first diagnostic methods is a blood test to measure creatinine levels and the estimated glomerular filtration rate (eGFR). Increased blood creatinine and decreased eGFR are clear signs of kidney failure. At the same time, urine tests to detect protein, red blood cells, or albumin can also help determine the extent of kidney damage.
Kidney imaging and biopsy
When basic tests are not enough to determine the cause or extent of kidney damage, imaging techniques such as kidney ultrasound, computed tomography (CT), or magnetic resonance imaging (MRI) will help evaluate the kidney structure and find abnormalities. In some cases, a kidney biopsy is necessary to determine the exact cause of kidney failure, especially when the disease is due to glomerulonephritis or autoimmune diseases.
Combined with clinical symptoms, these tests help doctors make an accurate diagnosis and choose the appropriate treatment for the patient.
Stages of Chronic Kidney Disease (CKD)
Chronic kidney disease (CKD) is a progressive condition in which kidney function gradually declines over time. The development of CKD is often very insidious. If not detected and treated promptly, the disease can lead to end-stage renal failure (ESRD), requiring alternative treatments such as dialysis or kidney transplantation. Dividing CKD into stages helps monitor the progression of the disease and determine appropriate treatment.
Stage 1: Normal kidney function (eGFR ≥ 90)
In the early stages, kidney function is still relatively normal. However, signs of kidney damage, such as protein in the urine, may begin to appear. Although the eGFR remains above 90, risk factors such as diabetes or high blood pressure must be closely controlled.
Stage 2: Mild kidney failure (eGFR 60-89)
At this stage, kidney function has begun to decline, but clinical symptoms are often not obvious. However, blood tests such as creatinine may begin to increase slightly. Treatment focuses mainly on controlling risk factors to slow the progression of the disease.
Stage 3: Moderate kidney failure (eGFR 30-59)
At this stage, kidney failure has become more obvious. Symptoms such as fatigue, edema, and changes in urination may appear. Treatment becomes more complex, aiming to control the condition and prevent the disease.
Stage 4: Severe kidney failure (eGFR 15-29)
Kidney function declines dramatically, and the patient may begin to experience more severe symptoms, including nausea, shortness of breath, and chest pain. At this point, preparation for renal replacement therapy, such as dialysis, is essential.
Stage 5: End-stage renal failure (eGFR < 15)
This stage is the stage of complete kidney failure, with almost no kidney function left. Patients need dialysis or a kidney transplant to sustain life.
Early recognition and treatment at each stage can reduce the risk of progression to later stages of the disease, providing opportunities to improve the patient's quality of life.
Treatment options for kidney failure
Kidney failure is a serious condition, and effective treatment is crucial to preventing dangerous complications, preserving remaining kidney function, and maintaining quality of life. Treatment options for kidney failure depend on the stage of the disease, the cause of kidney failure, and the patient's overall health.
Medical treatment and lifestyle changes
In patients with early-stage kidney failure, medical treatment plays a key role. Managing risk factors such as diabetes and high blood pressure is important. In addition, lifestyle changes with appropriate diet (low salt, low protein diet), weight control, and maintaining a reasonable level of activity help slow the progression of the disease. ACE inhibitors and angiotensin II antagonists are commonly used to protect the kidneys.
Renal Replacement Therapy
When kidney failure progresses to end-stage renal disease, patients need renal replacement therapy to sustain life. The two most common methods are dialysis and kidney transplantation. Dialysis removes waste and excess fluid from the body, while kidney transplantation is the optimal option for patients with a suitable donor kidney. Although kidney transplantation can provide a near-normal life, patients must maintain a lifelong regimen of immunosuppressive drugs to prevent rejection of the transplanted kidney.
Supportive Treatment
In cases of severe renal failure, supportive treatments such as specialized nutritional therapy, cardiovascular interventions, or treatment of complications such as infection, anemia, and electrolyte disturbances are essential to improve the patient's quality of life.
Each treatment requires continuous monitoring and appropriate adjustments to achieve optimal results.
Preventing and Maintaining Kidney Health
Protecting kidney health is important in maintaining body function and preventing serious diseases. Although kidney failure can have many causes, taking preventive measures and maintaining healthy kidneys will help reduce the risk of disease and prolong kidney life.
Controlling underlying conditions
One of the most important factors in preventing kidney failure is effectively managing underlying conditions such as diabetes, high blood pressure, and cardiovascular disease. This includes maintaining stable blood sugar and blood pressure levels, using medications as prescribed, and following a suitable diet. Regular health check-ups to detect early signs of kidney damage are also important.
Healthy diet and exercise
A healthy diet rich in fruits, vegetables, and foods low in sodium will reduce the kidney's burden, limiting the risk of damage. At the same time, maintaining an active lifestyle with moderate exercise will help control weight and improve blood circulation, supporting effective kidney function. Avoid bad habits such as smoking, excessive alcohol consumption, or improper use of painkillers, as these factors can gradually damage the kidneys.
Drink enough water and avoid toxins
Maintaining the body's hydration level is important for the kidneys to filter and excrete waste effectively. Drinking water daily helps prevent problems such as kidney stones and urinary tract infections. In addition, avoiding exposure to toxic substances or drugs that damage the kidneys, such as non-steroidal anti-inflammatory drugs (NSAIDs), is a necessary measure to protect the kidneys.
With a combination of a reasonable diet, controlling underlying diseases, and healthy living habits, preventing and maintaining kidney health is completely possible, helping to protect kidney function in the long term.
Conclusion
Kidney failure is a complex disease that can lead to serious consequences if not detected and treated promptly. Early recognition of symptoms and timely medical intervention will help protect kidney function and prevent dangerous complications.
In addition, preventing kidney failure through managing underlying diseases, maintaining a healthy diet, and a scientific lifestyle plays a decisive role in keeping the kidneys healthy. This will contribute to reducing the risk of chronic kidney disease and improving the quality of life for patients.
Current treatments, including medical treatment, dialysis, and kidney transplantation, have helped millions of patients maintain life and improve their health. However, it is important to continue to raise public awareness and develop advanced treatments.
