The criteria for a macrosomia is usually a baby with a birth weight of 4 kg or more. Normally, a newborn born at full term weighs around 2.5 kg to 4 kg and babies weighing more than 4 kg at birth are usually referred to as macrosomic. There are many reasons for the formation of a giant baby, such as genetics, diabetes during pregnancy, and excessive nutritional intake during pregnancy. Macrosomia may lead to a number of adverse consequences such as obstructed labor during delivery, asphyxia, shoulder dystocia, prolonged labor, vaginal lacerations, and excessive chances of postnatal illnesses in the fetus. It is recommended to choose the appropriate mode of delivery under the guidance of a doctor to avoid adverse consequences. Therefore, during pregnancy, it is recommended to undergo regular obstetric checkups in hospitals, have a reasonable diet, and control the weight of the fetus appropriately, so as to reduce the rate of the emergence of giant babies.
