The symptoms of chronic kidney failure are related to the severity of the condition; the more severe the kidney failure, the more symptoms the patient will have. In the early stages, patients may not feel uncomfortable or show any symptoms. Some patients may experience swelling in the lower limbs and facial area. Others may display clinical signs such as elevated blood pressure and visible blood in the urine. As kidney failure progresses and blood creatinine levels exceed 442 umol/L, patients may experience fatigue, which is due to renal anemia. Some patients may also experience a loss of appetite, nausea, vomiting, and other gastrointestinal symptoms.

What are the symptoms of chronic kidney failure?

Chronic kidney failure generally may have some clinical symptoms, but many patients do not have any discomfort. Some common clinical symptoms mainly include increased urine foam and decreased urine output. Due to the decline in renal function for urine excretion, it can lead to edema, particularly in areas such as both ankles and the face. In the state of renal failure, patients may also experience hyperkalemia and metabolic acidosis. Due to metabolic acidosis, patients might exhibit deep and labored breathing. In the advanced stages of kidney failure, patients may suffer from renal anemia, leading to fatigue and potentially experiencing bone pain and susceptibility to fractures due to renal osteodystrophy.

Chronic Kidney Failure Various Indicators

In patients with chronic kidney failure, the primary indicator to observe is obviously kidney function. It is essential to regularly monitor the patient's blood creatinine and urea nitrogen levels, which are generally required to be tested every 1 to 3 months when chronic kidney failure is stable. Additionally, urine output should be monitored. If there is a decrease in urine output and swelling occurs, it may indicate that the patient's kidney function is continuously deteriorating. A complete blood count should also be checked to observe changes in the patient's anemia status. Chronic kidney failure often causes hypertension, so blood pressure monitoring is also necessary for these patients. Electrolyte monitoring is important as kidney failure can lead to disturbances in calcium and phosphorus metabolism and subsequent secondary hyperparathyroidism. Therefore, the levels of calcium, phosphorus, and parathyroid hormone also need to be tested.

Chronic Renal Failure Replacement Therapy

Chronic kidney failure is the irreversible loss of nephron units and kidney function caused by the progressive progression of chronic kidney disease, leading to a clinical syndrome characterized by the retention of metabolic products and toxins, disturbances in electrolyte and acid-base balance, and endocrine disorders. Chronic kidney failure often progresses to end-stage kidney disease, and the late stage of chronic kidney failure is called the uremic stage. After entering the uremic stage, renal replacement therapy is often required, with the main methods being hemodialysis, peritoneal dialysis, and kidney transplantation.

Can chronic kidney failure CKD5 be cured?

The so-called CKD refers to chronic kidney disease. According to the glomerular filtration rate, CKD is divided into 5 stages, where stage 5 means that the patient's glomerular filtration rate has fallen below 15 milliliters per minute, which is equivalent to uremia. Chronic renal failure is irreversible and cannot be recovered, so it is impossible for patients whose condition has progressed to later stages to recover. Therefore, for such conditions, the only option is to choose renal replacement therapy so that the patient can survive. Renal replacement therapy mainly includes hemodialysis, peritoneal dialysis, or kidney transplantation.

Can chronic renal failure be cured by dialysis?

Patients with chronic renal failure can undergo dialysis treatment to sustain life and improve quality of life. However, dialysis merely uses artificial means to excrete accumulated metabolic wastes and fluids in the body, regulate the internal environment, and simply substitutes for the function of the kidneys. Dialysis has no therapeutic value for renal failure itself. Therefore, patients with chronic renal failure should not expect dialysis to restore kidney function. Nonetheless, as a renal replacement therapy, dialysis can provide patients with a relatively good lifespan and quality of life. Dialysis treatment is necessary for patients with uremia.
