Information for Patients


Childbirth Problems

While childbirth usually goes well, complications can happen. They can cause a risk to the mother, baby, or both. Possible complications include

  • Preterm (premature) labor, when labor starts before 37 completed weeks of pregnancy
  • Problems with the umbilical cord
  • Problems with the position of the baby, such as breech, in which the baby is going to come out feet first
  • Birth injuries

For some of these problems, the baby may need to be delivered surgically by a Cesarean section.

Postpartum Care

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.

  • Get as much rest as possible. You may find that all you can do is eat, sleep, and care for your baby. And that is perfectly okay. You will have spotting or bleeding, like a menstrual period, off and on for up to six weeks.
  • You might also have swelling in your legs and feet, feel constipated, have menstrual-like cramping. Even if you are not breastfeeding, you can have milk leaking from your nipples, and your breasts might feel full, tender, or uncomfortable.
  • Follow your doctor's instructions on how much activity, like climbing stairs or walking, you can do for the next few weeks.
  • Doctors usually recommend that you abstain from sexual intercourse for four to six weeks after birth.

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 Drug Use

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

  • Tobacco. Smoking during pregnancy passes nicotine, carbon monoxide, and other harmful chemicals to your baby. This could cause many problems for your unborn baby's development. It raises the risk of your baby being born too small, too early, or with birth defects. Smoking can also affect babies after they are born. Your baby would be more likely to develop diseases such as asthma and obesity. There is also a higher risk of dying from sudden infant death syndrome (SIDS).
  • Drinking alcohol. There is no known amount of alcohol that is safe for a woman to drink during pregnancy. If you drink alcohol when you are pregnant, your child could be born with lifelong fetal alcohol syndrome disorders (FASD). Children with FASD can have a mix of physical, behavioral, and learning problems.
  • Illegal drugs. Using illegal drugs such as cocaine and methamphetamines may cause underweight babies, birth defects, or withdrawal symptoms after birth.
  • Misusing prescription drugs. If you are taking prescription medicines, carefully follow your health care provider's instructions. It can be dangerous to take more medicines than you are supposed to, use them to get high, or take someone else's medicines. For example, misusing opioids can cause birth defects, withdrawal in the baby, or even loss of the baby.

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.
