The glomerular filtration rate of 79ml/min needs to be judged in conjunction with the age, gender, and weight of the person being examined, and cannot be generalized. Under normal circumstances, the glomerular filtration rate is usually between 80 and 120 ml/min, and after the age of 30 years, the glomerular filtration rate decreases by 10 ml/(min.1.73m2) every 10 years, and the glomerular filtration rate of males is about 10 ml/min higher than that of females. If the examination is performed in a young adult, a glomerular filtration rate of 79 ml/min suggests a mild decrease in glomerular filtration rate. It may be ultra-early stage of renal disease, or renal function damage caused by taking drugs, etc.. It is necessary to improve the examination to find the cause of the disease and treat the symptoms. If the examination is carried out in the elderly, glomerular filtration rate of 79ml/min may be normal. Calculated according to the proportion of glomerular filtration rate decreasing with age, the glomerular filtration rate of 60~70 years old is usually considered normal at 60~100ml/min. If patients find abnormal glomerular filtration rate, it is recommended to go to regular hospitals in time, improve the examination to clarify the cause of the disease, and then give targeted treatment or therapy under the guidance of the doctor.
