The relationship between edema and urinary protein in pregnant women is that some diseases cause protein to be lost from the urine, resulting in hypoproteinemia, a decrease in intravascular colloid osmotic pressure, and the formation of edema. If a pregnant woman suffers from hypertensive disorders of pregnancy, such as preeclampsia, the pregnant woman will have proteinuria, which causes a decrease in plasma colloid osmotic pressure in the body, and body fluids leak out into the tissue interstitial space, causing edema. If a pregnant woman suffers from kidney disease, such as glomerulonephritis, nephrotic syndrome, etc., the kidney function is impaired, resulting in a large amount of proteinuria, which will also cause the body’s colloid osmolality to decrease, and the tissue interstitial space is filled with fluid, resulting in edema in women. If a pregnant woman has edema and proteinuria, she needs to pay attention to it and be alert to the occurrence of kidney disease or hypertensive disease, she can go to the hospital in time to clarify the cause of edema and proteinuria, and then carry out targeted treatment and management.
