What does it feel like when the amniotic fluid breaks?

Amniotic fluid is an important substance that protects the fetus. When the fetal membranes surrounding the amniotic fluid rupture and the fluid leaks out, this is referred to as membrane rupture or "water breaking." The sensation of water breaking varies among individuals but mainly presents as a sudden gush of fluid from the vagina, similar to the feeling of urinary incontinence. However, unlike urine, amniotic fluid is clear and transparent and may have a slight fishy odor.

When the discharge is heavy, it may feel like uncontrollable urination, with fluid running down the legs. When the discharge is lighter, it may simply feel like sudden wetness in the underwear, with a continuous or intermittent moist sensation. This kind of fluid leakage cannot be controlled by holding in urine, and differs from normal vaginal discharge or urine.

The causes of water breaking are complex. Common causes include genital tract infections, as inflammation can compromise the integrity of the fetal membranes; multiple pregnancies or polyhydramnios (excessive amniotic fluid) can lead to high intrauterine pressure, which can also easily cause membrane rupture. Additionally, external forces such as abdominal trauma or impact on the pregnant woman's abdomen can also lead to rupture of the fetal membranes.

Once amniotic fluid leakage is suspected, the pregnant woman should immediately lie flat, elevate her hips to prevent further significant loss of amniotic fluid and to avoid umbilical cord prolapse, and then promptly call 120 or go to the hospital. She should remain lying flat as much as possible during transportation to the hospital.
