What Causes Spina Bifida? Unknown Scientists
believe environmental and genetic elements cause this defect There are various factors that allow people to be at risk
Folic Acid
Keeps blood healthy and helps body produce new cells Reduces neural tube defects by 70% to 80% 400 mcg before pregnancy and 800 mcg during pregnancy Found in vitamin supplements and food products Http://www.everywomancalifornia.org/documents/UserFiles/Image/folic_acid_supplement( 1).jpg
Other Risk Factors Race Gender Anti-seizure
medications
Diabetes Obesity Increased
body temperature
Prenatal Tests Can Detect Spina Bifida Medical
Ultrasonography Maternal Serum Alpha Fetoprotein (MSAFP) Amniocentesis
