The reason for this is that there are many causes of proteinuria, which are mainly classified as benign and pathological, and we would like to introduce several causes of proteinuria. 1, dehydration If you have a fever in your life, then transient proteinuria may occur due to dehydration when you have a fever. In addition, if you do strenuous exercise in life or take some kind of painkillers, it can also trigger temporary proteinuria, but this temporary proteinuria will gradually disappear after a period of time. The occurrence of proteinuria is very much related to the change of position, which is clinically called postural proteinuria and is usually found in young people. If you have long walks, strenuous exercise and long periods of standing in life, it will increase the chances of proteinuria formation, which will disappear when lying down. 3, inflammatory infections Proteinuria has a lot to do with inflammatory infections, if you have repeated infections of cystitis or pyelonephritis in your life, then after the occurrence of infection, the patient will have proteinuria, and once this infection is controlled, the symptoms of proteinuria will improve and gradually disappear. Warm reminder: If you have persistent proteinuria in your life, you should be alert to the irreversible destruction of the renal tubules. This condition is pathological proteinuria and needs to be treated immediately in hospital to avoid damage to life and health.
