If a routine urine test is performed and weakly positive urine protein is found, it can be observed first and the causative factors, such as strenuous exercise, staying up late, exertion, exposure to heat sources, etc., should be removed. If, during dynamic observation, urine protein turns negative, no treatment is needed. If it is still weakly positive or positive, or becomes strongly positive, this condition can be treated by giving drugs to lower urine protein, such as Huangkui capsules, Valsartan capsules, and Benadryl tablets. It is also important to deal with the cause of the disease. For example, if it is caused by chronic nephritis, treatment such as anti-platelet aggregation and blood pressure control should be given. If it is caused by systemic lupus erythematosus, hormones and immunosuppressants need to be given to treat it. If the amount of urine protein gradually increases during the observation process, suggesting that it is caused by nephrotic syndrome, hormones and anticoagulant and lipid-lowering drugs should be given to treat it, together with immunosuppressive drugs if necessary.
