What are birth defects?
Birth defects are health conditions that are present at birth. They change the shape or function of one or more parts of the body and can affect any part of the body (such as the heart, brain, foot, etc). They may affect how the body looks, works, or both.
There are thousands of different birth defects and they can be very mild or very severe. Some do not require any treatment, while others may require surgery or lifelong medical interventions.
What causes birth defects?
We know what causes certain birth defects. For instance, drinking alcohol while you are pregnant can cause your baby to be born with physical birth defects and mental impairment. And genetic conditions, such as cystic fibrosis or sickle cell disease, are the result of inheriting a mutation (change) in a single gene. However, we do not know what causes the majority of birth defects. In most cases, it is a number of complex factors. The interaction of multiple genes, personal behaviors, and our environment all may all play a role.
Can we prevent birth defects?
Most birth defects cannot be prevented. But there are some things that a woman can do before and during pregnancy to increase her chance of having a healthy baby:
- See your healthcare provider before pregnancy and start prenatal care as soon as you think you’re pregnant.
- Get 400 micrograms (mcg) of folic acid every day. Folic acid reduces the chance of having a baby with a neural tube defect.
- Avoid alcohol, cigarettes, and “street” drugs.
- Talk to your provider about any medications you are taking, including prescription and over-the-counter medications and any dietary or herbal supplements. Talk to your provider before you start or stop taking any type of medications.
- Prevent infections during pregnancy. Wash your hands and make sure your vaccinations are up to date.
- Make sure chronic medical conditions are under control, before pregnancy. Some conditions, like diabetes and obesity, may increase the risk for birth defects.
- Learn about your family health history.
