Macrosomia refers to a very large body size. It is often used to describe an oversized fetus.
A fetus (baby) of a mother with diabetes may be exposed to high blood sugar (glucose) levels throughout the pregnancy.
A C-section is the delivery of a baby through a surgical opening in the mother's lower belly area. It is also called a cesarean delivery.
