Fetal abnormalities refer to physical or functional differences in a developing fetus that can affect its health and development. These abnormalities can occur due to genetic factors, environmental influences, or a combination of both. Some common types include structural issues, such as spina bifida or cleft lip, and chromosomal disorders like Down syndrome. Detection of fetal abnormalities often occurs through prenatal screening and diagnostic tests, such as ultrasound or amniocentesis. Early identification can help parents and healthcare providers make informed decisions about care and treatment options, potentially improving outcomes for the child.
