Small for Gestational Age

Sometimes children who are born small for their gestational age don’t catch up in growth by age 2-4. Norditropin® is used to treat children who are short (in stature) because they were born small (small for gestational age—SGA) and have not caught up in growth by age 2 to 4 years.

What does “gestational age” mean?

When a doctor speaks about gestational age, they are referring to the age of a baby starting from the time when that baby was conceived. Babies who are small for gestational age (SGA) are simply born smaller than they should be when compared to other infants of the same gestational age. They may be smaller in weight, in length, or both.

Catching up.

Most babies born small for gestational age catch up to normal size and height within 6-12 months of age. However, some may not experience catch-up until age 2. Premature babies (born before 37 weeks of gestation) may take even longer to catch up, at about 4 years of age. In some cases, infants who are born small for gestational age will remain well below average height throughout their lives.

Your child’s health care provider will carefully monitor your child’s growth to determine how he or she is keeping up with other children the same age.

Seeing an endocrinologist.

A child who was born small for gestational age and has not caught up in height by age 2 to 4 may be referred to a pediatric endocrinologist, a doctor who specializes in hormone diseases in children. The endocrinologist can help tell if there is any other reason why catch-up growth isn't occurring, such as a nutritional problem or something else, like a genetic (inherited) disease.
