The causes of anemia in chronic renal failure, also known as renal anemia, occur in chronic kidney disease and are related to chronic renal failure. There are multiple reasons for this anemia, such as the lack of raw materials for red blood cell production caused by chronic renal failure, including deficiencies in iron, folic acid, and vitamin B1, shortened lifespan of red blood cells, and blood loss including non-gastrointestinal blood loss. Moreover, uremic toxins including parathyroid hormone can suppress the production of red blood cells in the bone marrow. However, the primary cause is the decreased production of erythropoietin by the kidneys during chronic renal failure.

Can patients with chronic renal failure have sexual intercourse?

Patients with chronic renal failure can have sexual intercourse, but there are prerequisites. Since sexual activity is physically demanding and requires adequate cardiopulmonary function, patients can engage in sexual activity if they do not experience chest tightness or shortness of breath and their blood pressure is well controlled. If there are no obvious symptoms of fatigue, difficulty breathing, or chest tightness during sexual activity, there should be no significant problems. However, since the patients have chronic renal failure, it is advisable to avoid conception unless prepared for pregnancy. Pregnancy can further burden the kidneys in female patients and potentially exacerbate chronic renal failure. Male patients with chronic renal failure may be taking medications that could affect sperm quality. Therefore, contraception should be practiced unless preparations have been made.

Chronic Renal Failure Treatment Plan

The treatment of chronic renal failure primarily requires a clear understanding of the cause, and treatment targeting the cause is essential to slow the progression of chronic renal failure. The most common causes of chronic renal failure are diabetes, hypertension, and chronic nephritis. Therefore, for patients with chronic renal failure caused by diabetes, insulin is often needed to control blood sugar. For patients with hypertensive kidney disease, antihypertensive drugs are certainly necessary to control blood pressure. However, in the early stages of renal failure, ACE inhibitors or ARBs are the preferred choices. For patients with chronic nephritis in the early stages, corticosteroid medications are required for treatment. However, if the serum creatinine has already exceeded 256 micromoles per liter, treatment then focuses mainly on managing complications, and corticosteroids are no longer used. (Please use medications under the guidance of a doctor.)

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.

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.
