Kidney failure is becoming an increasingly important global health problem, especially as the rates of chronic kidney disease and end-stage renal disease (ESKD) are rising rapidly. The number of people with kidney disease is expected to continue to rise by 2030, especially in countries with high rates of diabetes and hypertension.
Kidney disease, although preventable, is often overlooked until symptoms become severe. This increases the number of patients requiring dialysis or kidney transplantation, placing a heavy burden on the health system.
Kidney failure symptoms often appear when kidney function is severely reduced.
Understanding Kidney Failure
Kidney failure, a serious and increasingly common condition, affects the kidneys' ability to filter waste and maintain fluid balance in the body. As kidney function declines, harmful substances build up in the blood, leading to serious health problems. This condition can occur suddenly (acute kidney failure) or develop slowly over many years (chronic kidney failure), affecting a patient's quality of life and ability to live.
Kidney Function
The kidneys are key in filtering the blood, removing waste, and maintaining electrolyte balance. Any disruption in this function can lead to problems in the body, from high blood pressure to heart problems.
Causes of Kidney Failure
Major factors such as diabetes, high blood pressure, and chronic kidney disease are common causes. However, kidney infections, genetic disorders, or even long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs) can also play a role.
Diagnosis and Treatment
Diagnosing kidney failure requires blood and urine tests and imaging tests such as a kidney ultrasound. Treatment may include medications, lifestyle changes, and, in severe cases, dialysis or a kidney transplant.
Early Symptoms of Kidney Failure
Kidney failure, a disease that progresses silently, often does not manifest itself clearly until the condition becomes serious. However, early symptoms can indicate that the body is experiencing kidney dysfunction. Recognizing these signs in time will help prevent dangerous complications later.
Fatigue and Weakness
One of the most noticeable and common symptoms is persistent fatigue, as the kidneys cannot remove toxins and waste from the body, leading to lethargy and lack of energy. Fatigue can be accompanied by muscle weakness, affecting the ability to perform daily activities.
Changes in Urination
Patients with kidney failure may experience decreased urination or even be unable to urinate normally. Sometimes, urine may become foamy or bloody, a sign that the kidneys are not filtering waste products or that there is damage to the filtering organs.
Swelling and Fluid Retention
The buildup of fluid due to the kidneys' inability to excrete it properly leads to swelling, especially in the extremities, such as the legs, ankles, or hands. This symptom may start mild but can become serious if not treated promptly.
High Blood Pressure
The kidneys are responsible for filtering waste and helping regulate blood pressure. When kidney function is impaired, blood pressure can rise, causing headaches and dizziness, and can lead to serious heart problems if left unchecked.
Recognizing these signs early and seeking medical advice as soon as you suspect them is the first step in protecting your kidney health and improving your quality of life.
Symptoms of Advanced Kidney Failure
As kidney failure progresses, the body gradually loses its ability to maintain basic kidney functions, accumulating toxic substances and disrupting many systems. Symptoms at this stage often become obvious and seriously affect the quality of life. Recognizing these signs in time helps patients intervene and control the condition.
Nausea, Vomiting, and Loss of Appetite
When the kidneys cannot remove waste products, they accumulate in the body, causing frequent nausea and vomiting. At the same time, patients may also lose their appetite, leading to weight loss and fatigue.
Difficulty Breathing and Swelling
The accumulation of water in the body causes swelling in the limbs and can also cause fluid to accumulate in the lungs, leading to difficulty breathing. This symptom can occur even when the patient rests and worsens when lying down.
Urinary Disorders and Blood in the Urine
Patients with advanced kidney failure often have problems with urination, such as less urination, nocturia, or even blood in the urine. Urine may be dark or foamy, indicating that the kidneys can no longer filter waste effectively.
Chest Pain and Irregular Heartbeat
When kidney function is severely impaired, potassium levels in the blood may increase, causing symptoms such as irregular heartbeat and chest pain. These are warning signs of cardiovascular problems related to kidney failure.
If kidney failure progresses and is not detected and treated promptly, it can lead to serious complications. Recognizing these symptoms early on can help improve disease control and reduce health risks.
Symptoms of End-Stage Kidney Disease (ESKD)
End-stage kidney disease (ESKD) is a condition in which the kidneys lose their ability to function almost completely, which can be life-threatening if not treated promptly. At this stage, symptoms become severe and obvious, causing a serious decline in overall health. These signs can affect every system in the body and require immediate treatment.
Swelling and Fluid Retention
When kidney function is completely impaired, the body cannot eliminate excess water, leading to swelling in the limbs, face, and abdomen. The fluid accumulation can spread throughout the body, causing discomfort and increasing pressure on internal organs.
Shortness of Breath and Extreme Fatigue
The fluid accumulation in the lungs reduces the ability to breathe, making the patient feel short of breath even when resting. At the same time, chronic fatigue due to the kidneys being unable to filter waste effectively leads to exhaustion and an inability to maintain basic functions.
Arrhythmias and Chest Pain
ESKD patients often experience cardiovascular problems, especially irregular heartbeats and chest pain. This occurs due to changes in electrolytes in the body, such as high potassium levels, which can lead to sudden and severe heart attacks.
Loss of Appetite and Sudden Weight Gain
ESKD patients often lose their appetite, accompanied by nausea and vomiting. The buildup of toxins in the body can also cause severe weight loss or rapid weight gain due to fluid retention.
End-stage kidney disease is life-threatening and requires aggressive intervention such as dialysis or a kidney transplant to improve the patient's quality of life. Recognizing these symptoms early is key to reducing risk and preventing dangerous complications.
When to See a Doctor
When your body sends out unusual signals, it is extremely important to listen and respond promptly, especially for symptoms related to the kidneys. Early detection and treatment of kidney diseases can help prevent serious complications, protect your health, and improve your quality of life. However, when is the right time to seek medical attention?
Frequent and New Symptoms
If you experience symptoms such as persistent fatigue, changes in urination, or swelling in the legs and ankles may be a warning sign of kidney disease. In particular, if your urine is unusual in color or accompanied by blood, see a doctor immediately. The appearance of these symptoms, even mild, should not be ignored.
High Blood Pressure and Chronic Headaches
High blood pressure is one of the factors that cause kidney disease. If you constantly experience headaches, dizziness, or lightheadedness, it is a sign that your body is having problems with kidney function. These symptoms often appear when the kidneys cannot regulate blood pressure effectively.
Changes in Health Status
These signs cannot be ignored when you feel sudden changes in your body, such as shortness of breath, nausea, and unexplained weight loss. Early examination and diagnosis will help detect kidney-related diseases, helping to improve your health before it is too late.
Seeing a doctor when you notice any unusual symptoms related to the kidneys will give you the opportunity to effectively treat and protect kidney function and prevent serious diseases.
Diagnosing Kidney Failure
Diagnosing kidney failure is an important process in the early detection and management of the disease to prevent progression to serious stages. This process requires a combination of laboratory tests, imaging tests, and clinical evaluation to determine the extent of kidney damage and find the cause of the disease. Early detection of kidney failure will help minimize complications and improve treatment effectiveness.
Blood Tests: Creatinine and eGFR
A blood test, specifically measuring creatinine levels, is one of the most important tools in diagnosing kidney failure. High levels of creatinine in the blood indicate that the kidneys no longer function effectively. To assess the degree of kidney function decline, doctors also use the estimated glomerular filtration rate (eGFR), an important indicator that helps determine the stage of kidney disease.
Urine Tests: Protein and Blood
Urinalysis provides valuable information about kidney health. The presence of protein or blood in the urine indicates that the kidneys are damaged. Tests such as the microalbuminuria test can also help detect small kidney lesions that other testing methods cannot.
Imaging Diagnosis: Ultrasound and CT Scan
Imaging methods such as renal ultrasound or CT scan help evaluate the kidney structure and detect tumors, kidney stones, or abnormalities in the kidney structure. This is an important complementary tool in determining the cause of kidney failure.
Early diagnosis of kidney failure through the above methods will help the doctor come up with an appropriate treatment plan, from changing lifestyle and using medication to applying intervention methods such as kidney dialysis or kidney transplant when necessary.
Preventing Kidney Failure
Kidney failure is preventable if you are aware of it and take preventive measures early. Protecting your kidney health helps maintain kidney function and improves your quality of life. Lifestyle changes and controlling risk factors are important in preventing kidney disease.
Managing Underlying Diseases
Medications such as diabetes and high blood pressure are the main causes of kidney failure. Control of blood sugar and blood pressure through a proper diet, medication, and regular health check-ups will help reduce the risk of kidney disease. This is especially important for people with a family history of kidney disease.
Healthy Diet and Lifestyle
Maintaining a balanced diet, reducing salt and processed foods, and drinking enough water daily helps the kidneys function effectively. Limiting the consumption of harmful substances such as tobacco and alcohol will reduce the burden on the kidneys. In addition, regular exercise, maintaining an ideal weight, and avoiding excessive stress are also important factors in preventing kidney failure.
Regular Kidney Health Checks
One of the most effective ways to prevent kidney failure is to have regular kidney health tests, especially for those at high risk, such as diabetics, those with high blood pressure, or those with a family history of kidney disease. Early detection of abnormalities will help with timely treatment and minimize kidney damage.
These preventive steps will help protect kidney function, limit disease progression, and improve overall health.
Conclusion
Kidney failure is a serious disease that can cause many complications that affect overall health. Timely recognition and treatment of symptoms will help reduce the progression of the disease and improve quality of life.
Preventing kidney failure through controlling underlying diseases, maintaining a healthy lifestyle and performing regular tests is the most effective way to protect kidney function.
Kidney health care requires initiative from patients, especially those at high risk.
