Information for Patients


Postpartum Care

Also called: Post-pregnancy health

Taking home a new baby is one of the happiest times in a woman's life. But it also presents both physical and emotional challenges.

In addition to physical changes, you may feel sad or have the "baby blues." If you are extremely sad or are unable to care for yourself or your baby, you might have a serious condition called postpartum depression.
