Preconception care is one of the interventions that contributes to healthy pregnancy and positive pregnancy outcomes. It aims to prevent disease and factors that may affect pregnancies through provision the necessary nutrients for fetal development and prevention of exposure or consumption of toxic/teratogenic chemicals that may cause obstetric complications or alteration throughout the development of the child. This field of intervention relies mainly on the concept that environmental factors are associated to the well-being of a person in such a way that the well-being of the unborn fetus is dependent on the environment. In the article, it has implied in many instances that the unborn fetus is more sensitive to the changes in the environment as they are small and undeveloped. For example, minute amounts of lead exposure can lead to neurotoxicity and delayed development. In fact, the established safe lead concentrations has been revised many times as it continuously poses a serious risk and thus, set in stone the concept that there is no such thing as a safe concentration. Even the widely used antibiotics can pose a risk for the fetus as alteration of the uterine microbiome. With such a great danger and costs to the mother and unborn child, it is important that everyone is educated about it to raise its relevance so that families can provide a safe and optimal environment prior to conception and to lessen our reliance on such harmful substances through social movements and reforms.
