Toxins and Pregnancy Besides the known risks, there lurks a vast gray area in which the research is inconclusive. According to the March of Dimes web site, the cause of about 70% of birth defects is unknown. And most known defects are due to genetic or other unpreventable causes -- not to mom's exposure to toxic chemicals, foods, drugs, or infections. So is there any way to lower the risk? The following information should help you separate the facts from the likely fiction. Known Risks . Substances that can cause birth defects are called teratogens. Exposure to them does not automatically put your fetus at risk. The level and length of time of exposure, as well as the stage of the pregnancy at time of exposure, can come into play.

Birth defect Birth defects (or congenital defects) are defects in a baby at birth, or which develop in the first month of life. There are two main types of congenital defect. The first is caused by genetic abnormalities, which are hereditary. The second is caused by conditions (such as infectious diseases) which a baby gets from its mother.

Birth Defects Almost 20% of deaths in newborns are caused by birth defects. Abnormalities can occur in any major organ or part of the body. Major defects are structural abnormalities that affect the way a person looks and require medical and/or surgical treatment. serious illness in the mother, such as an under-active thyroid, or diabetes mellitus, in which her body cannot process sugar, also can cause birth defects in the child. In fact, in 2003, it was shown that babies of diabetic mothers are five times as likely to have structural heart defects as other babies.
