Normal people also have a small amount of protein in their urine. A 24h urine protein quantification greater than 0.15 grams is called positive urine protein, which is often seen in some kidney damage, such as glomerulonephritis, lupus nephritis, IgA nephropathy, hypertensive kidney damage, diabetic nephropathy and other diseases. The presence of positive urine protein requires active treatment, because long-term urine protein will not only lead to complications such as hypoproteinemia, inflammation and infection, but also directly damage the kidneys and lead to reduced kidney function. For treatment, we must first clarify the cause of the disease and choose a treatment plan according to the amount of urine protein quantification, as well as the kidney function and the type of kidney pathology. For example, chronic nephritis can be treated with ACEI or ARB drugs to reduce urine protein and creatinine, and oral Bering capsules to protect the kidneys, while lupus nephritis and nephrotic syndrome need to be treated with hormones or immunosuppressive drugs. In addition to medication, diet should be low salt, low fat, high quality and low protein as the principle, which can reduce the burden of the kidney.
