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.

Pregnancy and Substance Abuse

When you are pregnant, you are not just "eating for two." You also breathe and drink for two. If you smoke, use alcohol or take illegal drugs, so does your unborn baby.

To protect your baby, you should avoid

If you are pregnant and you are doing any of these things, get help. Your healthcare provider can recommend programs to help you quit. You and your baby's health depend on it.
