Pregnant women with urinary protein 1 + has little effect on fetal development, but it is necessary to regularly review the urine protein or quantitative urine protein examination, to exclude pregnant women combined with other organic pathologies.
Proteinuria is mainly categorized into physiological and pathological. Pregnancy is a common cause of physiologic proteinuria. Due to the large size of the fetus in the second trimester of pregnancy, it will compress the renal blood vessels, resulting in increased leakage of urinary protein; at the same time, the pregnant mother’s kidneys also have to undertake the excretion of metabolic wastes from the fetus, and the burden on the kidneys is increased, and there will be a small amount of protein leakage into the urine, resulting in positive urinary protein.
At this time the urine protein 1 + will not affect the health of mother and child, after delivery usually will gradually return to the normal range.
The common pathology of urinary protein in pregnancy is often due to renal lesions caused by various factors. When the kidneys are diseased, the glomerular vascular permeability increases, and the phenomenon of protein passing through the glomeruli into the urine occurs. Common causes include: hypertension during pregnancy and so on.
Therefore, if the presence of urinary protein 1+ in pregnant women is a physiologic phenomenon, it usually does not have a significant impact on fetal development, but it is necessary to monitor blood pressure and regularly review urinary protein. If the urine protein worsens or other new discomforts occur, it is necessary to consult a doctor in time to identify the primary disease to avoid adverse effects on the fetus.
