![]() ![]() ![]() ![]() If the baby has oesophageal atresia or a tracheo-oesophageal fistula, then there is a risk that they will breathe in milk when they start feeding as they are unable to swallow it properly. Oesophageal atresia can sometimes be associated with a connection between the food pipe and the breathing pipe (trachea), that condition is caused a tracheo-oesophageal fistula. If the oesophagus does not connect to the stomach and instead the pipe is closed at the end, then the baby is unable to swallow the fluid properly and the fluid builds up this condition is called oesophageal atresia. Very occasionally the excess fluid is caused because the baby is unable to swallow properly: normally the food pipe (oesophagus) connects to the stomach allowing the swallowed urine to pass into the digestive system of the baby. Sometimes it is caused by the mother having diabetes in pregnancy which causes the baby to have higher blood sugar levels and therefore pass sugar into their urine which in turn causes them to pass extra urine. Often no cause for the polyhydramnios is found. In the majority of mild cases there is no cause for the polyhydramnios. The amount of extra fluid is measured during an ultrasound scan and is categorised as mild, moderate or severe. This may have been detected by you measuring large for dates and referred for a growth scan or found by chance during an antenatal ultrasound scan. In cases of polyhydramnios there is more fluid than expected surrounding the baby. The amount of amniotic fluid surrounding the baby is therefore due to the balance between how much urine the baby is producing and how much the baby is able to swallow. The amniotic fluid is also swallowed by the baby. The amniotic fluid is produced by the baby producing urine (wee). The fluid that surrounds the baby inside the womb is called amniotic fluid. There is often no cause found but sometimes this can be associated with problems related to the baby’s swallowing. Polyhydramnios is a condition where there is excess fluid surrounding the baby in the womb. ![]()
