Low Sodium Diet in Oligohydramnios Assigned for Conservative Management
Low Sodium Diet in Oligohydramnios Assigned for Conservative Management
The investigators want to examine whether low salt diet can increase the amniotic fluid index
 in patients diagnosed with oligohydramnios and assigned for conservative management. A
 randomized controlled trial
Few studies have addressed the changes in maternal diet as affecting the composition and
 amount of amniotic fluid.

 Some articles have shown an increase in amniotic fluid volume as a result of maternal
 hydration during pregnancy through intravenous fluid infusions and oral fluid intake, the
 increase was evident in women with amniotic fluid and women with normal amniotic fluid
 volume. In a mechanism similar to that of liquid hydration, a low-salt diet may lead to an
 increase in the volume of amniotic fluid.

 The investigators would like to examine whether a low-salt diet in women with amniotic fluid
 is able to significantly increase the amount of amniotic fluid compared with a regular diet.
Inclusion Criteria:

 an amniotic fluid index at the 5th percentile or below, according to the current
 gestational age
