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 become pregnant?

Although patients with renal failure are not absolutely unable to become pregnant, pregnancy is ultimately a burden on the kidneys. Pregnant patients with renal failure may experience further deterioration of kidney function and may face numerous complications during pregnancy, such as heart failure, severe anemia, etc., which may pose some risks. However, there are still very rare case reports, including successful pregnancies in patients on dialysis for uremia, but the probability of this is extremely small, and the risks involved are too great. Generally speaking, it is not recommended for female patients with chronic renal failure to become pregnant.

Chronic Kidney Failure Various Indicators

In patients with chronic kidney failure, the primary indicator to observe is obviously kidney function. It is essential to regularly monitor the patient's blood creatinine and urea nitrogen levels, which are generally required to be tested every 1 to 3 months when chronic kidney failure is stable. Additionally, urine output should be monitored. If there is a decrease in urine output and swelling occurs, it may indicate that the patient's kidney function is continuously deteriorating. A complete blood count should also be checked to observe changes in the patient's anemia status. Chronic kidney failure often causes hypertension, so blood pressure monitoring is also necessary for these patients. Electrolyte monitoring is important as kidney failure can lead to disturbances in calcium and phosphorus metabolism and subsequent secondary hyperparathyroidism. Therefore, the levels of calcium, phosphorus, and parathyroid hormone also need to be tested.

Is stage five chronic kidney failure serious?

Strictly speaking, there is no condition called "chronic renal failure stage five," but there is a term "chronic kidney disease stage five." Chronic kidney disease is divided into five stages based on the glomerular filtration rate (GFR). Stage five chronic kidney disease indicates that the patient's GFR is less than 15 milliliters per minute, which is about 15% of normal kidney function and is essentially equivalent to uremia. Therefore, chronic renal failure or chronic kidney disease stage five is very dangerous and can cause many complications. Moreover, this type of kidney failure is irreversible and incurable, and the patient may need to undergo dialysis or a kidney transplant.

What are the symptoms of chronic kidney failure?

Chronic kidney failure generally may have some clinical symptoms, but many patients do not have any discomfort. Some common clinical symptoms mainly include increased urine foam and decreased urine output. Due to the decline in renal function for urine excretion, it can lead to edema, particularly in areas such as both ankles and the face. In the state of renal failure, patients may also experience hyperkalemia and metabolic acidosis. Due to metabolic acidosis, patients might exhibit deep and labored breathing. In the advanced stages of kidney failure, patients may suffer from renal anemia, leading to fatigue and potentially experiencing bone pain and susceptibility to fractures due to renal osteodystrophy.

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.
