Oligohydramnios: A Condition Leading To Low Levels Of Amniotic Fluid


Amniotic fluid is the best life supporting system for your baby, because it provides complete protection for your baby and also helps in the growth of limbs, muscles, digestive system and lungs.

Formation of amniotic fluid takes place immediately after the formation of the amniotic sac, i.e. about 12 days after conception.

Your baby will move and topple in your womb with the aid of amniotic fluid. During the second trimester, your baby begins to breathe and swallow the amniotic fluid.

Sometimes, however, the levels of amniotic fluid will be too high or too low. If the level of amniotic fluid is too low, the condition is known as oligohydramnios.

When you go for a prenatal check-up, your practitioner will measure the level of amniotic fluid by using different methods such as deep pocket measurement or amniotic fluid index evaluation (AFI).

If the AFI method shows the fluid index less than 5cm or the fluid volume less than 500ml during 32-36 weeks, a diagnosis for oligohydramnios is likely.

Every year, about 8% of pregnancies are recognized with low amniotic fluid. You may be affected with this condition at any time during your pregnancy, but you will observe the condition most frequently during the third trimester.
