Why does water break suddenly at 28 weeks of pregnancy?
Generally, water breaking refers to the leakage of amniotic fluid due to rupture of the fetal membranes. Sudden water breaking at 28 weeks of pregnancy may be caused by factors such as intense physical activity, poor development of the fetal membranes, abnormal fetal position, bacterial vaginosis, or cervicitis. The details are as follows:
1. Intense physical activity: Vigorous exercise may increase intrauterine pressure, placing excessive stress on the fetal membranes and causing them to rupture.
2. Poor development of the fetal membranes: The fetal membranes serve as a protective layer around the fetus and must develop fully during pregnancy. If the membranes do not develop properly, they may become thin or fragile, making them more prone to rupture, leading to amniotic fluid leakage or premature rupture of membranes.
3. Abnormal fetal position: This refers to an incorrect fetal position within the uterus, such as transverse or breech presentation. Such positions may increase the risk of membrane rupture, resulting in water breaking.
4. Bacterial vaginosis: Bacterial vaginosis is a vaginal infection caused by bacterial overgrowth. The infection may lead to cervical relaxation, increasing the risk of premature rupture of membranes.
5. Cervicitis: Cervicitis may cause cervical relaxation and shortening, making the fetal membranes more susceptible to rupture, which can result in amniotic fluid leakage and preterm labor.
If sudden water breaking occurs at 28 weeks of pregnancy, it is recommended to seek medical treatment under a doctor's guidance, including medications such as dexamethasone acetate tablets and magnesium sulfate injection, while also ensuring adequate rest.
