If you are a woman who may become pregnant, taking folic acid on a daily basis before pregnancy can help prevent serious birth defects in your unborn baby.
All women who could become pregnant are at risk of having babies with neural tube defects. These are serious birth defects that consist of abnormalities in the baby's brain, skull or spine.
Women can work with their health professionals to reduce this risk significantly by seeking their advice on how to take folic acid.
The neural tube is the part of the developing baby that eventually becomes the brain and spinal cord. Neural tube defects (NTDs) occur when the neural tube fails to close completely during the early weeks of pregnancy. At this early stage, many women do not even know that they are pregnant. About 260 babies are born each year in Canada with an NTD.
Spina bifida is the most common NTD. The effects of spina bifida are quite varied. These effects can range from severe physical disabilities and developmental delay, to problems that can be corrected by surgery. The most common effects are limited use of the lower limbs, and bowel and bladder limitations.
Another NTD is anencephaly, a condition in which the brain either fails to develop completely, or does not develop at all. Pregnancies affected by this condition often end in miscarriage. Babies born with anencephaly die very soon after birth.
Folic acid, or folate, one of the B vitamins is essential to the normal development of a baby's spine, brain, and skull, especially during the first weeks of pregnancy.
Research has shown that women who take a daily vitamin supplement containing folic acid before conception and in the early weeks of pregnancy can reduce the risk of having a baby with an NTD.
If you have a personal or family history of NTDs, you should consult your doctor. You may be advised to take a higher daily dosage of folic acid. If you have diabetes, epilepsy, or if you are obese, you may be at higher risk of having a baby with an NTD. You should discuss these risk factors with your doctor before planning your pregnancy.
Health Canada launched a national awareness campaign in March 2002, about the importance of folic acid in the prevention of birth defects. With this campaign, Health Canada is working in partnership with stakeholders, other governments and health care professionals to ensure that Canadian women of childbearing years are aware that they can reduce the risk of NTDs, by taking folic acid before pregnancy.
As part of its overall mission to help the people of Canada maintain and improve their health, Health Canada also conducts research on the health benefits of nutrition, and establishes national guidelines, including Canada's Food Guide to Healthy Eating, and Nutrition for a Healthy Pregnancy: National Guidelines for the Childbearing Years.
