Small for gestational age (SGA)

Alternate Names : Low birth weight

Definition

Small for gestational age (SGA) means a fetus or infant is smaller in size than normal for the baby's gender and gestational age.

Information

Ultrasound is used to find out if a fetus is smaller-than-normal for age (intrauterine growth restriction). The most widely used definition of SGA is birth weight below the 10th percentile.

A fetus with intrauterine growth restriction will be small in size and can have problems such as:

Increased red blood cells (polycythemia)
Low blood sugar (hypoglycemia)
Low body temperature (hypothermia)
