Fetal abnormalities refer to physical or functional issues that occur during the development of a fetus in the womb. These can result from genetic factors, environmental influences, or a combination of both. Common types include structural abnormalities, such as spina bifida or cleft lip, and chromosomal disorders, like Down syndrome. Detection of fetal abnormalities can occur through various prenatal screening methods, including ultrasound and blood tests. Early diagnosis allows for better planning and management of potential health issues, providing parents with important information about the baby's condition and possible interventions.
