Treatment of proteinuria needs to be treated in the nephrology department of the hospital. First, the degree of kidney damage and the cause of the appearance of urine protein should be clarified, and a suitable treatment plan should be chosen according to the type of kidney disease. The principle of treatment is to try to protect kidney function and then try to restore kidney function. Do not use drugs at your own discretion. Proteinuria is an increase in the amount of protein in the urine that exceeds the normal amount that can be filtered by the glomerulus. Generally speaking, a protein level of more than 3.5g/24h in the urine is called massive proteinuria. Once proteinuria occurs, we should first exclude physiological factors and postural factors, and then improve relevant examinations, such as kidney ultrasound, kidney function tests, urine routine tests, etc., to generally determine the situation of kidney damage, and if persistent proteinuria persists, it means that the degree of kidney damage is relatively large and must be treated in a timely manner. The appearance of urine protein is mainly due to abnormal kidney function, glomerular filtration dysfunction, resulting in too much filtered protein, commonly seen in chronic kidney disease, but the amount of urine protein leakage is not proportional to the condition, the leakage of urine protein in mild kidney disease patients is not necessarily less than in severe kidney disease patients, and needs to be combined with other related tests.
