How does macrosomia affect delivery options?

Macrosomia, which refers to a newborn who is significantly larger than average, typically weighing over 8 pounds 13 ounces (4,000 grams), is known to complicate delivery options. The increased fetal size can lead to various challenges during labor and delivery, contributing to a higher likelihood of cesarean delivery. This is primarily due to the increased risk of shoulder dystocia and other mechanical difficulties during vaginal delivery, which can pose risks to both the infant and the mother.

When the baby is larger, there is a greater chance that the pelvis may not accommodate the size of the baby, leading healthcare providers to opt for a cesarean section to avoid potential complications. This surgical intervention is often considered a safer option when a baby's size places the mother or infant at risk during the process of labor. Therefore, macrosomia is directly linked to an increased risk of cesarean delivery as a necessary intervention for safe delivery.
