Compensation period for renal function reserve
The reserve compensatory capacity of the kidney is very large, even if its function has decreased, its ability to excrete metabolites and regulate water and electrolyte balance will not be affected. It can still meet the normal needs of the body, during which time the body will not show any symptoms, and even if checked sometimes, it may show normal or only occasional slightly higher symptoms.
Renal insufficiency decompensation period
At this stage, the damage to the glomerulus has reached 60% to 75%, and the ability of the kidneys to excrete metabolic waste has shown certain obstacles.
Blood creatinine and urea nitrogen have already appeared high or exceeded normal values. Patients may experience symptoms such as anemia, fatigue, weakness, weight loss, and difficulty concentrating.
But this stage is often overlooked. If there are situations such as dehydration, infection, bleeding, etc., obvious symptoms will soon appear.
Renal failure stage
During this period, renal function damage has become more severe, with kidney damage reaching 75% to 95%.
The function of the kidneys is no longer able to maintain the stability of the body's internal environment. At this time, patients may experience symptoms such as fatigue, fatigue, and inability to concentrate, which can be quite severe. Anemia is very obvious, with an increase in nocturia, a significant increase in blood creatinine and urea nitrogen, and often accompanied by acidosis, also known as renal failure.
During this period, glomerular damage has exceeded 95%, and patients have developed severe symptoms such as severe nausea, vomiting, oliguria, edema, malignant hypertension, severe anemia, itching of the skin, and a foul smell of urine in the mouth.
Patients with renal insufficiency must promptly understand the four stages and symptoms of each period of renal insufficiency. This allows for timely detection of one's symptoms and active treatment in a timely manner. As long as you persist in treatment, you can achieve improvement.
