Amniotic fluid deficiency occurs in summer

Israeli doctors warn summer heat may increase the risk of amniotic fluid level deficiency in pregnant women.

The study, published in the Archives of Gynecology and Obstetrics, finds lower levels of fluid in the womb of pregnant women more likely in the summer months.

It is important for pregnant women to drink appropriate amounts of water specifically in the summer -- about 10 glasses per day -- and avoid direct sun, not only for the health of the mother, but also in order to avoid fetal dehydration, Eyal Sheiner of Ben-Gurion University of the Negev in Beer-Sheva, Israel, says in a statement.

The researchers evaluated the pregnancies of 4,335 women -- out of 191,558 total deliveries at Beer-Sheva's Soroka University Medical Center between 1988 and 2007 diagnosed with this the low fluid condition -- oligohydramnios.

After excluding other causes of fluid loss, such as premature rupture of membranes or intra-uterine growth restriction, the study finds a proportionally higher number of those with idiopathic oligohydramnios -- 1,553 deliveries, or 36 percent -- occurred during the four summer months.
