Patients with chronic renal failure generally have anemia combined with stage three or above of chronic kidney disease (CKD). When the hemoglobin falls below 100 grams per liter, it is necessary to start treatment to correct anemia. At this point, relevant lab tests should be conducted to check for abnormalities in folate, vitamin B12, ferritin, and serum iron levels, and specific treatments should be administered accordingly. Treatments generally include iron supplements, erythropoiesis-stimulating agents, folate, and vitamin B12 to help correct anemia.

What are the symptoms of chronic kidney failure?

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.

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.

Does chronic renal failure require dialysis?

Not all cases of chronic renal failure require dialysis. It is only considered when chronic renal failure progresses to an advanced stage, causing severe consequences, and the kidneys are unable to maintain normal body functions, leading to many complications. Generally, when chronic renal failure progresses to its final stage, i.e., uremia, the kidney function is left with about 10% capacity. The body then experiences a disruption in its internal environment, including the accumulation of a large amount of metabolic waste, serious electrolyte disorders, and severe metabolic acidosis. It is at this point that dialysis is considered. In the early stages of chronic renal failure, dialysis is not necessary.

Diet for Patients with Chronic Renal Failure

Patients with chronic kidney failure should first pay attention to a low-salt and low-fat diet, with daily salt intake less than six grams, and try to eat less salty food such as pickled vegetables and preserved products. Additionally, due to the impaired excretion of potassium and phosphorus in patients with chronic kidney failure, it is necessary to eat less high-phosphorus and high-potassium foods. Common high-phosphorus foods include various marinated meats and other processed foods, and common high-potassium foods include fruits such as bananas, peaches, mangoes, and vegetables like green vegetables and potatoes. At the same time, it is important to maintain a high-quality, low-protein diet. If dialysis treatment has not yet been started, protein intake should be controlled at 0.6 grams per kilogram of body weight per day. If dialysis treatment has already begun, the standards can be appropriately relaxed.

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.
