Sikiönaltistus

Sikiönaltistus refers to the exposure of a fetus to various substances, conditions, or environments during pregnancy. This exposure can occur through the mother's body, with substances like alcohol, nicotine, certain medications, and environmental toxins crossing the placenta. Infections during pregnancy can also lead to fetal exposure. The timing and duration of exposure, as well as the dose of the agent involved, significantly influence the potential effects on fetal development.

These exposures can have a wide range of consequences, from subtle developmental changes to severe congenital abnormalities. Some well-known examples include Fetal Alcohol Spectrum Disorders (FASD), which result from maternal alcohol consumption, and the effects of certain infections like rubella during pregnancy. The field of teratology studies these adverse effects on the developing embryo and fetus.

Preventing sikiönaltistus is a key aspect of prenatal care. Healthcare providers advise pregnant individuals to avoid harmful substances, manage chronic conditions, and take precautions against infections. Understanding and mitigating these potential exposures are crucial for promoting healthy fetal development and reducing the risk of birth defects and developmental problems. Research continues to identify new risk factors and develop strategies for prevention and intervention.
