There is increasing evidence that the mother's health status has an influence on the baby and the course of pregnancy. Eating habits, exposure to certain toxicants, stress or the environment are factors influencing the pregnant woman and, thus, the baby's well-being.
There are certain external factors acting as teratogens, that is to say, prompting or increasing the chances for developing any congenital abnormality. There are different types of teratogens, such as anticonvulsants (a.k.a. antiepileptic drugs or AEDs), methotrexate (abbreviated MTX), ionising radiation, phytoestrogens, tobacco, alcohol, cocaine, and certain maternal diseases such as diabetes mellitus, hyperandrogenemia, or systemic lupus erythematosus.
To rule out the chances for an uncomplicated pregnancy, the mother-to-be has to follow a pre-conception care, especially in cases where there is any previous maternal disease. If you have any further questions during pregnancy, please do not hesitate to ask your healthcare provider.
