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.

What should I do about coughing caused by chronic kidney failure?

Patients with chronic renal failure who experience coughing should first analyze whether it is caused by an infection. In such cases, routine blood tests and chest CT scans are needed to confirm whether there are any infectious lesions in the lungs. Additionally, it should be checked whether the patient has systemic lupus erythematosus, vasculitis, or other conditions, as these diseases can affect the lungs and cause pulmonary lesions leading to coughing. Therefore, treatment should be targeted based on the cause. If the cough is due to an infection, antibiotics are required, but the dosage must be adjusted according to the patient's kidney function. If the cough is due to pulmonary changes caused by a systemic disease, targeted treatment for the systemic disease is needed.

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.

How to test for chronic renal failure?

The examinations for patients with chronic kidney failure are divided into several aspects: First, it is necessary to confirm the presence of chronic kidney failure and assess its severity. This requires blood tests for kidney function, observing levels of blood creatinine and urea nitrogen, and performing endogenous creatinine clearance tests to determine the degree of kidney failure; Second, it is important to determine whether there are complications associated with kidney failure. Therefore, routine blood tests are necessary to check for renal anemia, blood pressure measurements to observe if there is renal hypertension, and blood tests for electrolytes to check for any electrolyte disorders. These patients also need to have their parathyroid hormone levels checked and undergo iron metabolism tests to provide a basis for further treatment.

Chronic renal failure inevitably has symptoms.

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.

Why does chronic renal failure cause vomiting?

Patients with chronic renal failure who experience vomiting generally indicates that their condition has become very severe. Typically, from stage four of chronic kidney disease onwards, a large amount of metabolic waste accumulates in the body, and patients may have severe metabolic acidosis, among other issues. These conditions can cause edema of the gastrointestinal mucosa, and these metabolic wastes can also irritate the gastrointestinal tract, leading to symptoms like nausea, vomiting, and loss of appetite. Of course, besides these reasons, other gastrointestinal diseases such as chronic gastritis, gastric ulcers, and even gastric cancer should also be ruled out.
