The fig fruit is well known for its powers as a laxative. The consumption of fig juice in large quantities is linked to loose stools. Those interested in consuming large quantities of fig juice for the many benefits or simply for the taste should build up to the desired amount. Otherwise, it is possible to suffer from abdominal cramping, pain, and diarrhea. Young children should particularly be watched closely if a great deal of fig juice is consumed. Normal amounts of fig juice should be safe for anyone.

Women who are pregnant or who suspect they may be pregnant should discuss fig juice side effects with their physician prior to consuming large quantities. There are no known fig juice side effects if consumed in smaller quantities.
