Pregnancy blood pressure down whether urine protein will drop is related to the patient’s condition, some patients can drop, some patients will not drop. If a pregnant woman with simple hypertensive disorders of pregnancy, under the action of sustained high blood pressure, glomerular dilatation, endothelial cell swelling, fibrin can be deposited in the endothelial cells, affecting glomerular filtration function, resulting in albumin leakage from the glomerulus, the formation of proteinuria, when the blood pressure is reduced, the sustained damage to the kidneys is reduced, and the urinary protein may decline. If the pregnant woman with gestational hypertension has a combination of renal diseases, such as glomerulonephritis, nephrotic syndrome, etc., the pregnant woman’s blood pressure decreases, the burden on the kidneys is reduced, but under the continued influence of the original renal disease, the urinary protein may not decrease, and in severe cases, it may even be further aggravated, or even renal failure may occur. When the pregnant woman body abnormalities, should be standardized treatment under the guidance of a professional physician, so as not to delay the condition, resulting in adverse consequences.
