Proteinuria is a condition in which the amount of protein in the urine exceeds normal levels, and a routine urine test indicates that the urine is positive for protein. If there is a significant increase in foam in urine during urination, and it does not dissipate easily, this is often referred to as “foamy urine”, which often indicates a high level of protein in urine, and may be proteinuria. How is proteinuria produced? We know that the kidneys are the body’s detoxification and drainage organs, under normal circumstances, protein and these “good substances” should not be discharged, let’s say the kidneys are like a sieve, the toxins, water, etc. out of the body, the large protein and these things stay, but various reasons lead to damage to the sieve, the sieve hole has become larger, so that the protein However, for various reasons, the sieve is damaged and the pores become larger, so that the protein is also shunted out with the toxins and water, and proteinuria appears in the urine. Therefore, once protein appears, it is often a sign of kidney damage. How can we detect it in time? Once foamy urine appears, it is important to go to the hospital for a routine urine test in time. If you have diabetes, hypertension or other diseases, if there is no obvious abnormality in urine routine, you need to check the ratio of urine protein to urine creatinine, which is more sensitive and can detect a small amount of abnormal urine protein. What are the risks of proteinuria? Long-term proteinuria will cause irreversible damage to the kidneys and gradually develop abnormal kidney function, which may progress to uremia in severe cases. Even a very small amount of proteinuria should be taken seriously to find the cause and treat it in time to reduce proteinuria and kidney damage. Now the urine routine is a basic item of physical examination, if the urine is positive for protein, you must go to the nephrology department for consultation, do not have the attitude of “can eat and drink, can have what disease”, generally appear kidney function abnormalities, it is often too late to regret.
