Urine malb, also known as urine microalbumin, is a very small amount of protein in our urine under normal circumstances, usually less than 30 mg/L. If there is an increase in urine microalbumin, it often reflects the early damage to the kidneys, which is a common clinical cause, such as the early stage of diabetic nephropathy, and glomerulonephritis and other causes such as The common clinical causes, such as early diabetic nephropathy, glomerulonephritis and pre-eclampsia, can all lead to elevated urine microalbumin. When there is an increase in urine microalbumin, we need to intervene in time, when the patient’s kidney damage may be effectively reversed or even recovered. First, we need to identify the cause of the disease, according to the cause of timely treatment, patients with diabetic nephropathy, we must actively regulate blood sugar; second, for patients with significantly elevated urine microalbumin, we also do 24h urine protein quantification. If the 24h urine protein quantification is more than 1g, we have to do a kidney pathology biopsy if necessary; Third, for patients with elevated urine microalbumin, we can take some drugs to lower urine protein.
