The normal value of urine microalbumin in diabetic patients should be less than 20μg/min. If the measured level of urine microalbumin is within this range, it is completely normal, and there is no need to worry about it, indicating that there is no combined diabetic nephropathy. If the measured urine microalbumin is greater than 20μg/minute and less than 200μg/minute, it belongs to early diabetic nephropathy, which should be paid special attention to control blood sugar and blood pressure on one hand, and take drugs to improve kidney microcirculation on the other hand. When urine microalbumin is greater than 200μg/minute or 24h urine protein quantification is greater than 0.5g/24h, it has reached clinical diabetic nephropathy, in addition to controlling blood sugar and blood pressure, you should also take oral drugs to reduce urine protein, such as Bailing capsule, Huangkui capsule type drugs, in addition to strictly control the amount of protein intake, especially plant-based protein to avoid increasing the burden on the kidneys, leading to Kidney failure may occur.
