What does SGA mean in pregnancy?

What causes SGA baby?

The causes of SGA are multifactorial and include maternal lifestyle and obstetric factors, placental dysfunction, and numerous fetal (epi)genetic abnormalities. Short-term consequences of SGA include increased risks of hypothermia, polycythemia, and hypoglycemia.

What are SGA babies at risk for?

A baby who is small for gestational age (SGA) has a lower weight than normal for the number of weeks of pregnancy. Sometimes this raises the risk of early birth, low birth weight, miscarriage and other problems.

Should SGA babies be delivered early?

The optimal gestation to deliver the SGA fetus

If MCA Doppler is abnormal, delivery should be recommended no later than 37 weeks of gestation. In the SGA fetus detected after 32 weeks of gestation with an abnormal umbilical artery Doppler, delivery no later than 37 weeks of gestation is recommended.

Why is SGA bad?

SGA may show that the baby is getting less oxygen than normal. This increases the health risks for the baby during pregnancy, delivery, and afterward. Babies with SGA may have problems at birth, such as: Lower oxygen levels.

Can SGA babies be normal?

SGA babies may be proportionately small (equally small all over) or they may be of normal length and size but have lower weight and body mass. SGA babies may be premature (born before 37 weeks of pregnancy), full term (37 to 41 weeks), or post term (after 42 weeks of pregnancy).

Do SGA babies sleep more?

In prior studies, longer sleep duration is associated with lower BP, and SGA is associated with shorter sleep duration in childhood.

Do SGA babies catch up?

Postnatal growth of SGA

The majority of infants born SGA experience catch-up growth in the first few months, followed by a normal pattern of development. Catch-up growth of infants born SGA mainly occurs from 6 months to 2 years and approximately 85% of SGA children will have caught up by age 2 years2,17,18,19).

Are small babies healthy?

If there are no other complications, low birth weight babies usually ‘catch up’ in their physical growth. In later life, however, people who were born smaller than average are more likely to develop diabetes, obesity, heart problems and high blood pressure.

How can I avoid small for gestational age?

Can small size for gestational age be prevented? Prenatal care is important in all pregnancies. It is especially helpful to see any problems with the baby’s growth. For a healthy pregnancy, stop smoking if you smoke, and don’t use drugs or alcohol while you are pregnant.

How do you tell the difference between SGA and IUGR?

What are the differences between IUGR and being born SGA? IUGR describes a reduction of the fetal growth rate but is not defined by the subsequent birth weight, whereas birth weight is used to define SGA. It is therefore possible for a baby to be born SGA but with no prior IUGR.

Do SGA babies have small heads?

The mean head circumference (presented as an SD from reference circumference) of SGA children (–0.98) was significantly smaller than that of AGA children (+0.09; P<. 001).

What do fetuses do when their mothers are highly stressed?

Infants whose mothers experienced high levels of stress while pregnant, particularly in the first trimester, show signs of more depression and irritability. In the womb, they also are slower to “habituate” or tune out repeated stimuli — a skill that, in infants, is an important predictor of IQ.
