Prenatal exposure refers to the contact a developing fetus has with various substances or environmental factors while still in the womb. This can include exposure to drugs, alcohol, tobacco, certain medications, and environmental toxins. Such exposures can potentially affect the fetus's growth and development, leading to various health issues after birth. The effects of prenatal exposure can vary widely, depending on the timing, duration, and type of exposure. For example, Fetal Alcohol Syndrome is a condition that can result from a mother's consumption of alcohol during pregnancy, leading to physical and cognitive impairments in the child. Understanding these risks is crucial for promoting healthy pregnancies.
