The normal range of 24-hour urinary protein is ≦0.15 g. Once it exceeds 150 mg/day, it is an abnormal urinary protein. If the abnormality persists, the urine protein represents a lesion in the kidney. But in many cases, urine protein is not really caused by increase in protein, mostly caused by the following factors:
In normal life, some people often have gross hematuria, the urine color looks like the meat wash water sample or as the black tea and the soy sauce, generally after 1-2 weeks can be turned into microscopic hematuria, and then slowly disappear, under the general microscope Hematuria will disappear within 6 months. In this part of the patient, there is usually a significant reduction in urine volume at the beginning of the disease, and some patients even have no urine.
If the condition lasts more than three days, it means that the condition is serious. At this time, azotemia blood urea nitrogen is more than 7.14 mmol/l, which all indicate that the kidney function has been damaged. During the recovery period of the disease, urine volume gradually increased as high as over 2000 ml, indicating that the kidney has been restored to health.
Proteinuria is most easily confused with urine protein. Common in patients with acute nephritis, urine foam often increase, and the urine foam will increase or decrease with the severity of the disease, but proteinuria disappears slower than other symptoms. Sometimes proteinuria may continue for 1-2 months after the edema has largely disappeared.
Proteinuria can gradually subside after two months, but some patients need longer. For patients with proteinuria, the same precautions should be taken to prevent the condition from worsening.
Some patients show eyelid edema, which is a symptom of patients with milder symptoms. If the symptoms are severe, it may lead to edema of the patient throughout the body and may even cause pleural effusion, ascites and other symptoms. Therefore, in the presence of edema, it is necessary to go to the hospital for treatment as soon as possible.
Symptoms of edema usually begin to subside within 2-3 weeks, while others require more time. After edema recedes, proteinuria will improve and urine volume will increase gradually.
Urine is also easily confused with proteinuria in patients with hypertension, and a large number of studies have found that about 80% of patients with acute nephritis have high blood pressure. If blood pressure keeps rising, it is likely to be a precursor to chronic glomerulonephritis, a time when kidney disease is more severe and the risk of progression to renal failure is high. Pay attention to the difference between urine protein and other urine abnormalities. Symptomatic treatment is the key to cure the disease!pre：Why are some patients with more severe symptoms, the better the treatment effect?
