It is always important to have good nutrition while you are pregnant and make sure you take your prenatal vitamins. Some birth defects may be prevented if pregnant mothers follow these rules. Spina bifida is a birth defect that may be prevented if you have enough folic acid in your diet. About one in every 2000 babies have spina bifida. Spina bifida is a birth defect that affects the bones of the spine. The bones do not form properly around the spinal cord. The name spina bifida literally mean "split" or "open" spine in Latin.

Spina bifida occurs during the first month of pregnancy. Sometimes before the mother even knows she is pregnant. This is why it is important to try to be in good health and eating right when you plan to become pregnant. Spina bifida happens when the two sides of the embryo's spine do not completely fuse together. There are some cases where the spinal cord may protrude through the opening that is not fused.

Researchers still don't know exactly what causes spina bifida. There is evidence that suggests that genes may be involved, but in most cases there is no connection. If a woman has a high fever during pregnancy, there is an increased risk of it. Folic acid has been linked to reducing the risk of spina bifida. Taking certain drugs to control epilepsy have also been linked to a higher risk of spina bifida. It is most common for babies whose mothers are of British ancestry. A woman who already has one child with spina bifida will more likely have another one with it.

There are two types of spina bifida. Spina bifida occulta and spina bifida manifesta. Spina bifida occulta is the mildest form. It is also the most common. The defect is hidden under the skin and usually does not cause any problems. There is an estimate of 10 - 20% of the general population that have this form of spina bifida and do not even know it. In these cases there are a few tell tale signs that someone may have spina bifida. These people may have a birthmark, depression, dimple or a hairy patch on the skin over where the vertebrae are affected.

Spina bifida manifesta is a more severe form and a more rare form. It usually is associated with problems walking, bladder problems and coordination. This type of spina bifida can be separated into two classes, meningocele and myelomeningocele. In meningocele the fluid leaks out of the baby's spinal cord. This causes a swollen area of the spine. Myelomeningocele is when some of the spinal nerves push out of the spinal canal against the underside of the skin. The nerves are usually damaged. In the very worst cases the skin is split open as well and the nerves are exposed to the outside. Most babies who are born with this kind of spina bifida will have hydrocephalus, which is accumulation of fluid in and around the brain.
