Fetal programming refers to the concept that conditions and experiences during pregnancy can influence the development of the fetus, potentially affecting health outcomes later in life. Factors such as maternal nutrition, stress, and exposure to toxins can shape the fetus's growth and organ development, leading to long-term effects on metabolism, immune function, and susceptibility to diseases. Research suggests that these early influences can set the stage for conditions like obesity, diabetes, and cardiovascular diseases in adulthood. Understanding fetal programming emphasizes the importance of maternal health and well-being during pregnancy for the future health of the child.
