A critical step in pregnancy can significantly reduce the risk of certain birth defects. Understanding what is spina bifida is key to a healthier start for your baby.

What are the main causes of Spina Bifida?

  • Spina bifida is a neural tube defect, which occurs when the spine and spinal cord do not form properly in the first month of pregnancy.
  • The exact cause is unknown, but it's believed to be a complex mix of genetic and environmental factors, including a family history.
  • A key contributing factor is a deficiency in folate (vitamin B-9) before and during the early stages of pregnancy, which is crucial for development.

Key symptoms of Spina Bifida to watch for

  • Among the types of spina bifida, the mildest form, spina bifida occulta, often has no symptoms other than a small birthmark or tuft of hair.
  • The most severe form, myelomeningocele, involves a sac of fluid protruding from the back, containing part of the spinal cord and nerves.
  • General spina bifida symptoms can range from minor physical issues to severe mobility problems, bladder and bowel control issues, and learning disabilities.

How can you prevent Spina Bifida effectively?

  • The most effective prevention method is taking a daily supplement of 400 micrograms (mcg) of folic acid before and during early pregnancy.
  • Women who have had a prior pregnancy affected by a neural tube defect may need a higher dose of folic acid, as prescribed by their doctor.
  • Eating a diet rich in folate from foods like leafy green vegetables, beans, and fortified cereals also contributes to a healthy pregnancy.
