The causes of high glomerular filtration rate usually include gigantism, acromegaly, diabetic nephropathy and pregnancy, etc., which need to be treated in time once detected. In case of gigantism or acromegaly, the growth hormone in the patient’s body may be over-produced, which leads to high glomerular filtration rate, but this indicator is only suggestive for the diagnosis of the disease, and does not have diagnostic value; in addition, the glomerular filtration rate of patients with early-stage diabetic nephropathy is also high, which is usually related to glomerular hyperfiltration. In addition to disease factors, it may also be related to physiological factors such as pregnancy, in which the high glomerular filtration rate during pregnancy is mainly due to the physiological increase in renal blood flow during pregnancy, which is a normal phenomenon. If you have high glomerular filtration rate, you need to actively consult a regular hospital and follow the doctor’s instructions for reasonable treatment.
