Small for gestational age (SGA)

Overview

Most babies with SGA will catch-up to a normal length and/or weight by 2 years of age. Approximately 2.3% of all new-borns are born SGA.

Cause

Impaired growth of the baby while in the womb can be caused by a number of factors, including genetic, maternal, placental and demographic. Often the exact cause is not known.

Symptoms

Short stature is the main sign of SGA, other symptoms include poor appetite and reduced food intake, which results in leanness in comparison with children of the same age.

Diagnosis

Many babies will catch-up and return to normal growth within the first two years of life; however, some children will remain shorter. In some cases, children that do not catch up will need growth hormone therapy to help them to grow.
