Tip 126: oligohydramnios

The fetal causes of oligohydramnios include:

  • Chromosomal abnormalities, e.g. aneuploidy
  • Congenital abnormalities, especially those associated with impaired urine production, e.g. renal agenesis
  • Growth restriction (multiple causes, including maternal factors e.g. placental insufficiency)
  • Demise
  • Post-term pregnancy
  • Ruptured fetal membranes

Most cases, especially if mild / moderate, have no underlying cause found.
