What does small for gestational age mean?

Small for gestational age (SGA) means a newborn is much smaller than expected. Specifically, babies born with a birth weight and length that are below the 2.3rd percentile may be considered SGA.

“Gestational age” is the age of a baby based on the point of conception. So, it includes the time that babies spend growing in the womb. Most babies are born between 37 and 41 weeks of gestation. A gestational age assessment compares a newborn’s weight and length against the average weight and length for other babies of the same gestational age.

Why are some children born SGA?

There isn’t always a clear reason behind SGA. Some factors that may be associated with SGA include genetic defects or problems with the placenta. It can also be caused by issues with the mother’s health, such as malnutrition, chronic high blood pressure, or chronic infections.

Do babies born SGA “catch up”?

Most babies born small for gestational age will reach their expected height and size by the time they turn 2. Catch-up for babies who are born prematurely may take longer.

If catch-up growth isn’t seen by the age of 2 or 3, your child’s doctor may refer them to a pediatric endocrinologist.

How is SGA diagnosed?

SGA is defined by a child’s size, so doctors may take several measurements of the child’s body and map the results on a growth chart.

Doctors may also perform multiple tests to determine what is causing or contributing to the short stature of a child born SGA. These may include tests to see if a child has growth hormone deficiency or problems with their thyroid (a gland in the neck that produces hormones). Doctors may also do blood tests to look for celiac disease, kidney problems, and other conditions unrelated to hormones.

The results of these tests may help doctors determine what kind of treatment the child needs.

After the diagnosis

Children diagnosed with SGA may be prescribed growth hormone therapy. This involves taking regular doses of growth hormone to stimulate growth. Your child may have regular follow-up visits to monitor their growth and make sure that treatment is working well.

  • increased risk of growth of cancer or a tumor that is already present and increased risk of the return of cancer or a tumor in people who were treated with radiation to the brain or head as children and who developed low growth hormone problems. Contact the healthcare provider if you or your child start to have headaches, or have changes in behavior, changes in vision, or changes in moles, birthmarks, or the color of your skin
