The concepts of urine leakage and water breakage are different. Water breakage, usually seen in women in late pregnancy, refers to the fluid in the amniotic cavity that flows out of the vagina and may be accompanied by abdominal pain; urine leakage refers to the involuntary flow of urine from the urethra, which can happen to everyone. In addition, pregnant women can also distinguish between the two from the smell, discharge, controllability and other aspects, or the use of pH test paper for testing. 1, odor: amniotic fluid is usually colorless, odorless liquid, occasionally also light pink, and may be mixed with a small amount of blood; urine usually has a pungent odor, and the volatilization of the acidic component of the urine; 2, discharge: if there is a phenomenon of water breakage, usually a larger discharge, and lasts longer. And the duration is longer, can flow out when standing, and stop when lying down; Leakage of urine is usually discharged less, and the duration is shorter; 3, controllability: If you try to force pressure near the anus or contraction of the vagina, but still can’t control the liquid discharge, then most of the water breakage, with the uncontrollability; If you can control, it is usually leakage of urine; 4, acidity and alkalinity: the amniotic fluid is weakly alkaline, while the urine is weakly acidic, so those who are in a position to use a pH test paper to test the pH. pH test paper for testing. If the water breaks, the pH test paper is usually blue, which helps to distinguish the two more accurately. If the water breaks, it is recommended to lie down and rest immediately to help minimize the expulsion of amniotic fluid and avoid prolapse of the umbilical cord, which can lead to intrauterine oxygen deprivation of the fetus. It is also necessary to pay attention to keep the vulva clean, clean, sterilized towels can be placed on the vulva to prevent infection, and timely medical attention; if the leakage of urine, it is recommended to improve the relevant examinations in order to clarify whether it is a normal phenomenon in pregnancy or caused by other disease factors, and actively targeted treatment. In addition, if a pregnant woman is unable to distinguish between urine leakage and water breakage, she should go to the hospital in time to avoid affecting her pregnancy and causing adverse effects on her health.
