I.INTRODUCTION Oligohydramnios Definition Oligohydramnios is an abnormal condition occurring during pregnancy resulting from lack of amniotic fluid (fluid surrounding the baby in the uterus) This fluid plays a vital role in proper fetal development while its deficiency can lead to oligohydramnios sequence or Potter sequence characterized by an irregular appearance of the fetus or neonate. The onset of oligohydramnios usually occurs during the later part of the third trimester, often when one is overdue. The opposite to oligohydramnios is polyhydramnios, characterized by excessive amniotic fluid levels. CAUSES OF OLIGOHYDRAMNIOS In many cases, oligohydramnios is idiopathic with experts still trying to find out the exact cause responsible for the problems. The fetal urine mainly forms the amniotic fluid during the later stages of pregnancy. So, reduction in fetal urine production due to some pregnancy irregularity, such as obstruction of the fetal urinary tract, can lead to oligohydramnios. Signs of low amniotic fluid levels during the first or second trimester may indicate some fetal abnormalities. The common contributing factors include: Fetal Causes Leaky or Ruptured Amniotic Membranes: Sometimes, the amniotic fluid leaks out through a small tear or hole in the amniotic membranes, leading to Oligohydramnios. This can occur at any stage of pregnancy but is most common as one approaches delivery. Fetal Abnormalities: Absence of the kidney or any other kidney abnormality (renal agenesis, polycystic kidney) in the baby can also hamper urine production Genetic Factors: Inheriting abnormal genes in an autosomal recessive or autosomal dominant pattern Placental Causes Placental Abruptio]: Placental abnormalities, like a partial abruption, which causes the placenta to peel away from the inner uterus wall, may lead to amniotic fluid deficiency.
