What causes oligohydramnios?

Oligohydramnios can be caused by a variety of conditions. The most common causes of oligohydramnios include a pregnancy that has lasted for at least 42 weeks (post-term pregnancy) or a premature tear in the amniotic sac. Similarly, the health of the mother can affect amniotic levels. For example, low levels of amniotic fluid have been associated with conditions such as lupus (in which the immune system attacks normal tissues), high blood pressure, or diabetes in the mother. Some medication, specifically angiotensin-converting enzyme (ACE) inhibitors for treatment of serious heart diseases, may also cause low amniotic levels. Certain fetal disorders such as a genetic mutation, stunted growth, urinary or kidney problems, or problems with the heart or lungs may also cause oligohydramnios.
