Fetal growth research focuses on studying the growth and development of a fetus during pregnancy. This includes investigating factors that influence fetal growth, such as maternal nutrition, genetics, and environmental exposures. Researchers in this area study how fetuses grow in size and weight, as well as the development of organs and systems. Understanding fetal growth is essential for identifying potential risk factors for abnormal growth patterns and assisting in the early detection and prevention of complications during pregnancy. This research area also plays a crucial role in improving prenatal care and monitoring fetal health.
