The term "baby weight" refers to the extra pounds that many women gain during pregnancy. It is a common experience for expectant mothers and usually consists of a combination of increased fluid retention, growing uterus, placenta, amniotic fluid, and fat storage. The amount of baby weight gained can vary greatly from woman to woman, depending on factors such as genetics, diet, exercise habits, and the number of previous pregnancies. After giving birth, many women work towards losing this extra weight through a combination of healthy eating, regular physical activity, and patience.
