Newborns who are small for gestational age (SGA) are those who are born smaller than the average size for their gestational age. This condition occurs in about 8% of all live births and is more common in premature babies.
SGA babies may be born with more health problems than full-term babies, depending on how small they are. Common health issues include low blood sugar, breathing difficulties, jaundice, and hypothermia.
The causes of SGA can be divided into three categories: intrauterine growth restriction, placental insufficiency, and maternal factors. Intrauterine growth restriction is when the baby’s growth is restricted due to a medical condition or an issue with the placenta. Placental insufficiency occurs when the placenta is not able to provide the baby with enough nutrients and oxygen. Maternal factors can include smoking, poor nutrition, or certain medical conditions.
Diagnosis of SGA babies can be made through testing. A physical examination is usually performed and the baby’s size and weight is compared to expected measurements. Ultrasound may also be used to measure the baby’s size, and blood tests may be done to check for infections or other medical conditions.
SGA babies may require extra care in the newborn period. They may need extra monitoring for low blood sugar and other health problems. Babies may also need extra feedings or supplemental oxygen.
SGA babies are at greater risk for longer-term health issues such as developmental delays, problems with vision or hearing, and cognitive disabilities. Therefore, parents should be aware of these potential risks and be sure to follow up with their child’s doctor for regular checkups.
Newborns that are small for gestational age (SGA) are those that are born with a lower weight than would be expected for their gestational age. Depending on the cause, these babies may require extra care and monitoring. Here are some of the treatment options available for newborns that are SGA.
