How can I prevent constipation difficulty passing stool

Pregnancy makes the bowels work more slowly. This can make the stool harder, so it is more difficult to pass.

What to do to prevent it:

Drink at least 8 glasses of liquid every day.
Get regular exercise.
If you are taking iron tablets, try taking only one a day with fruit or vegetable juice. Or skip a few days.
Eat plenty of fruits, vegetables, and foods with fiber—like whole grains and cassava (manioc) root.
Do not take laxatives. They only solve the problem for a short while and then you need to take more.
