A recent research has diagnosed that those expecting mothers who take extra stress or suffer from blood pressure problems during their pregnancy are more likely to give birth to a baby with some birth defects. Medication has no effects on this strategy; whether the pregnant woman avoids medication for stabilizing her blood pressure or she follows the treatment, babies of such women have higher chances of being defected while birth.

According to few scientists from US, regardless of pregnant women taking medication in the first three months of their pregnancy or not, if they suffer from hypertension then their new born baby can enter his new life with malformations such as heart defects.

However, the findings of this research are different from that of a previous research which stated that some anti-hypertension medications that are used to manage high blood pressure in pregnant women can result into birth imperfections to new born babies. In particular, the scientists of that research have identified angiotensin-converting enzyme (ACE) inhibitors as one of the most frequently used anti-hypertension drugs that can cause a toxic effect on fetuses. This drug can cause weird malformations and stillbirths.

But according to this latest research that has been led by De-Kun Li of the Kaiser Foundation Research Institute in California, it is not the medication that can affect the fetuses; it is the matter of having high blood pressure that can cause malformations to the new born baby.

As written by Dr Li wrote in the study, published online by the British Medical Journal today "Therefore, our results do not support the argument that maternal use of ACE inhibitors in the first trimester significantly increases the risk of fetal malformations more than any other antihypertensive drug".
