Hi my wife Now 18 th month pregnant. First scanning made on 12 th Week in dat report amniotic fluid index is normal. In last scanning at 18 th week the anomaly usg scan showed amniotic fluid moderately reduced. So why it is reduced? Apart from all the scanning is normal but amniotic fluid index only reduced. So is it normal? In future it will be normal or not? Tell me details. We r worrying lot. So please ans me. Thank u.

reduction in fluid can be because of leakage of the fluid or due to some infection or kidney problem in the baby ..it needs to be assessed and the cause needs to be found out as it may lead to serious long term problems

When pregnancy occurs along with the baby, a structure named placenta is formed. This placenta is the one which forms the amniotic fluid. The baby passes urine which also maintains the amniotic fluid volume. So if the amniotic fluid is reduced it means there could be a problem with the placental function or baby's kidneys or both. Anomaly scan determines structure of a baby and its organs, even if it is normal it cannot say anything about function. It is better to take medicines to improve the amniotic fluid and if it does, to keep it in normal limits. If the amniotic fluid goes down further, to become severe oligohydramnios, at times it is an indication to terminate the pregnancy. So keep a watch and ask your wife to take 2.5 liters of water daily along with emdicines prescribed by your gynecologist.
