I also am concerned that the seriousness and risks of the amniotic fluid leak have not been explained to her. It is important to report the leak of any amniotic fluid to the doctor as soon as possible. This is to reduce the risk of infection caused by bacteria from the vagina entering the uterus. Also, once an amniotic fluid leak is determined no pelvic exam should be performed until after delivery is planned. This is so no further bacteria can be introduced into the birth canal and to prevent premature labor.
Amniotic fluid surrounds the fetus in the uterus and protects it from injury.
Too little amniotic fluid can interfere with normal development of baby's lungs and limbs, and indicate an anomaly. Too much fluid also can indicate an anomaly in the fetus. Now that it is certain that your sister is leaking amniotic fluid she needs to be sure to drink plenty of water to help replenish the fluid that has been lost. Also, most doctors advise that sexual intercourse be restricted until after the delivery. Poorly controlled gestational diabetes can endanger the fetus as well as the mother.
