We don't know what kind of disease this kidney failure is, let alone its symptoms. We still need to know more about this common knowledge. This can prevent unexpected situations, effectively pay attention to one's physical condition, and have a clear understanding of this disease. Next, let's all learn about what kidney failure is and prepare our bodies for better health.
Renal failure is a pathological state in which renal function is partially or completely lost in the later stages of various chronic kidney diseases.
Classification of renal failure:
Acute renal failure: The condition of acute renal failure progresses rapidly, usually due to insufficient blood supply to the kidneys (such as trauma or burns), functional impairment of the kidneys due to blockage by certain factors, or damage from toxins, leading to the occurrence of acute renal failure.
Chronic renal failure: The main cause of chronic renal failure is long-term kidney disease. Over time and as the disease progresses, the function of the kidneys gradually decreases, leading to the occurrence of renal failure.
What are the symptoms of renal failure?
Oligouria stage: The most critical stage of the condition, with severe internal environment disorder. Patients may experience oliguria (400ml per day) or anuria (100ml per day), low specific gravity urine (1.010-1.020), high urinary sodium, hematuria, proteinuria, tubular urine, etc. Severe patients can experience water poisoning, hyperkalemia (often the cause of death during this period), metabolic acidosis, and azotemia (progressive exacerbation can lead to uremia), which endanger the patient's life. This period lasts for several days to several weeks, and the longer it lasts, the worse the prognosis.
Polyuria stage: After the oliguria stage, the urine volume gradually increases. When the daily urine volume exceeds 500ml, it enters the polyuria stage. Afterwards, urine output multiplied day by day, with a maximum daily urine output of 3000-6000ml and even reaching over 10000ml. At the beginning of polyuria, although urine output increases, the renal clearance rate is still low, and the accumulation of metabolites in the body still exists. After about 4-5 days, serum urea nitrogen and creatinine gradually decrease with increasing urine volume, and symptoms of uremia also improve.
Recovery period: Urinary volume gradually returns to normal, and renal function gradually recovers after 3-12 months. Most patients' renal function can return to normal levels, while only a few patients develop chronic renal failure.
Regarding the symptoms of renal failure mentioned above, we have learned and mastered the characteristics of the symptoms through learning. In order to improve our physical health in the future, this knowledge is essential. In addition, if patients with renal failure need to learn more knowledge, please consult experts at the hospital, so that you will receive more detailed answers.
