Introduction
Glomerular filtration rate (GFR) is an indicator reflecting the glomerular filtration function. A slightly low GFR due to physiological reasons generally poses no significant harm. However, if it is caused by pathological conditions, it may lead to impaired kidney function and other complications. Treatment should be tailored according to the individual patient's condition. If glomerular filtration rate is found to be low, patients should seek evaluation at a正规 hospital to determine the underlying cause and receive appropriate treatment.
Glomerular filtration rate (GFR) is an indicator reflecting the filtering function of the glomeruli. A mildly low GFR due to physiological reasons generally poses no harm. However, if it results from pathological causes, it may lead to reduced kidney function and other complications.
1. No harm
The kidneys are the most important organs for excretion in the human body. In elderly individuals, a slightly decreased glomerular filtration rate may occur naturally. If kidney function tests show that creatinine and urea levels remain within normal ranges, this condition is considered normal and harmless, requiring no special intervention.
2. Potential harm
A low glomerular filtration rate suggests impaired glomerular filtration function, leading to accumulation of toxins and fluid in the body, along with elevated levels of serum creatinine and blood urea nitrogen. This may cause symptoms such as nausea, vomiting, a urine-like taste in the mouth, and loss of appetite. For acute kidney injury, prompt treatment targeting the underlying cause usually leads to improved kidney function, and many patients can fully recover. However, in cases of chronic kidney insufficiency or established kidney damage, the kidney's capacity for repair is limited, and treatment must be tailored according to the individual patient's condition.
If glomerular filtration rate is found to be low, it is important to seek evaluation at a正规 medical institution to determine the underlying cause and receive appropriate treatment.
