Patients with chronic renal failure, if they are male, can attempt to conceive under the guidance of a clinic doctor after discontinuing the use of medications that affect fertility; usually, there are no major issues for male patients. However, for female patients, attempting to get pregnant carries a significant risk because pregnancy increases the burden on all organs, including the kidneys, which can exacerbate kidney diseases, especially in cases like lupus nephritis. Nevertheless, not all patients with chronic renal failure are absolutely unable to conceive; some have successfully managed the risks associated with pregnancy. In such cases, it is necessary to weigh the pros and cons.

Precursors of renal failure

The kidneys have a very strong compensatory ability. When kidney function is slightly impaired, many people do not have any uncomfortable symptoms and feel everything is normal. However, if one actively seeks out early signs, it is possible to detect precursors to kidney failure. At this time, if one can go to the hospital in time for routine blood tests, urine tests, and kidney function tests, it is possible to determine if there is kidney failure. The most obvious precursor symptom of kidney failure is usually general fatigue, which many people tend to overlook. This is because there are indeed many reasons that can cause fatigue, especially since many people attribute it to fatigue or stress factors. Additionally, many patients with precursors to kidney failure experience edema, particularly the kind that disappears after rest, so it is especially not taken seriously. Another symptom of kidney failure precursors is a significant increase in the frequency of urination at night, which is also often overlooked.

Chronic Renal Failure Clinical Manifestations

Patients with chronic renal failure may exhibit fatigue, which is mainly due to anemia. Patients with stage three or higher chronic renal failure generally have anemia, which can lead to symptoms such as fatigue, palpitations, and pallor. Additionally, patients may experience nausea and vomiting, which are primarily caused by an increase in toxins. Furthermore, patients may also exhibit symptoms such as edema and shortness of breath, as individuals with chronic renal failure typically experience reduced urine output. A higher intake than output over time can lead to an increased circulating blood volume, resulting in heart failure.

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.

Can chronic renal failure be cured?

Chronic kidney failure is irreversible and incurable, with no possibility of kidney function recovery. There are many causes of chronic kidney failure, commonly including diabetic nephropathy, hypertensive nephropathy, chronic nephritis, polycystic kidney disease, etc. These causes affect the kidneys over the long term, resulting in extensive damage to kidney tissues. Since kidney tissues cannot regenerate, chronic kidney failure is incurable and irreversible. Patients with chronic kidney failure still require treatment to control the underlying causes leading to the condition, aiming to slow down the progression of the disease as much as possible, prolong the patient’s life, and ensure the quality of life. This is the primary goal of treatment.

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.
