Patients with chronic kidney failure do not necessarily have symptoms, and the symptoms of each patient are not exactly the same. Chronic kidney failure refers to the damage to the kidneys by various chronic kidney diseases, eventually leading to the kidneys' inability to adequately excrete metabolic waste, causing the accumulation of water and metabolic waste in the body. This leads to disturbances in the patient's electrolytes and may also present clinical symptoms such as anemia and hypertension. However, not all patients feel discomfort, so chronic kidney failure is also known as the silent killer. If a patient undergoes a blood test, it will show an increase in blood creatinine and urea nitrogen, which is the only common feature among all patients with chronic kidney failure.

What is best to eat for chronic renal failure?

Patients with chronic renal failure are advised to adopt a low-salt, low-fat, and high-quality protein diet. For those not undergoing dialysis, protein intake should be strictly controlled to 0.6 to 0.8 grams per kilogram of body weight per day. Additionally, patients with stage 3 CKD or above often experience electrolyte disorders, such as hyperkalemia, which can lead to cardiac arrest and arrhythmias. Therefore, it is important to avoid foods high in potassium, such as bananas, oranges, dates, kiwis, and tomatoes. Due to the strict protein intake, hypoproteinemia may occur, and these patients are also prone to hyperphosphatemia. It is recommended to choose foods with a low phosphorus to protein ratio, generally those with a ratio below fifteen. After starting dialysis, the same principles apply, but protein intake can be slightly increased, as some protein is lost during both hemodialysis and peritoneal dialysis. The protein intake can be adjusted to 1.0 to 1.2 grams per kilogram of body weight per day, while still controlling phosphorus and potassium intake.

Can people with chronic renal failure eat mutton?

Patients with chronic kidney failure can eat mutton. Although these patients have reduced ability to excrete metabolic waste due to kidney failure, and the body's metabolic wastes are mainly due to the products of protein metabolism, in reality, patients with chronic kidney failure need to control their protein intake in their diet to avoid excessive protein intake leading to the overproduction of metabolic wastes. This would increase the excretory burden on the kidneys, and protein can also increase the excretion of urinary protein in patients. The daily protein intake for these patients should be controlled at less than 80% of that for normal people, with animal proteins making up more than 50% of this intake. Since mutton is an animal protein, patients with chronic kidney failure can eat mutton, but they should not eat too much.

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.)

Causes of Anemia in Chronic Renal Failure

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.

Chronic kidney failure is not contagious.

Chronic kidney failure is not contagious. Strictly speaking, chronic kidney failure is not an independent disease; it is a state of disease. It refers to various causes that damage the kidneys, leading to the loss of kidney tissue, and ultimately, the kidneys lose their ability to perform excretory functions. This state is called chronic kidney failure. Chronic kidney failure itself is not contagious. Contagious diseases involve some type of pathogen, whereas the common causes of chronic kidney failure include chronic nephritis, diabetes, kidney diseases, hypertensive nephropathy, etc. None of these diseases are contagious, hence chronic kidney failure is also not contagious.
