Glomerular filtration rate at age 55 has some individual variation and is usually normal above 90 ml/min.
The glomerular filtration rate in adult resting state is about 80-120 ml/min in men and about 10% lower in women, and thereafter gradually decreases with age.
Glomerular filtration function is the most important physiologic function of the kidney and is the most commonly used clinical parameter to assess renal function. The magnitude of glomerular filtration rate is related to age. Glomerular filtration rate generally reaches its peak at the age of 25-30 years, and then gradually decreases with age.
The glomerular filtration rate of 55 years old people, no matter male or female, will not be lower than 90 ml/min. If it is lower than this value, it generally suggests that the glomerular filtration function has been impaired, and the lower the value is, the more serious the damage is, and the relevant examination should be improved, and the cause should be clarified and then actively treated.
In daily life, we should actively control high blood pressure, high blood fat, high blood sugar, nephrotoxic drugs and other risk factors that may threaten kidney health to avoid abnormal glomerular filtration rate, and if abnormalities are found, we should consult hospitals in time to clarify the cause of the disease.
