Do SGA babies have small heads?
What are the features of SGA baby
SGA babies may appear physically and neurologically mature but are smaller than other babies of the same gestational age. 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.

What are SGA babies at risk for
16 SGA infants have many perinatal complications, commonly preterm birth NEC (necrotizing enterocolitis) and adverse perinatal outcome, and is the second major cause for perinatal diseases and death, following premature birth, but there are still differences between the research findings, such as hypoglycemia.
Do SGA babies stay small
Although approximately 70%–90% of SGA infants show catch-up growth during the first years of life, individuals born SGA may continue to have a short stature in adulthood2,3).
What is small for gestational age SGA
The most common definition of small for gestational age (SGA) is a birth weight that is below the 10th percentile. At the time of the ultrasound exam, the provider may use other findings, such as the amount of amniotic fluid surrounding the baby, to further understand the baby's condition.
What causes small fetal head circumference
Microcephaly is a condition where a baby's head is much smaller than expected. During pregnancy, a baby's head grows because the baby's brain grows. Microcephaly can occur because a baby's brain has not developed properly during pregnancy or has stopped growing after birth, which results in a smaller head size.
What are the long term effects of SGA babies
Crude neurological handicaps, such as cerebral palsy, are extremely rare in children born SGA at term. Such handicaps are more common in very premature children. However, there does appear to be an increase in the risk for non-severe neurological dysfunction in individuals born SGA.
What are the long term effects of SGA
Accordingly, being born SGA may increase the risk of learning difficulties [4], lower academic performance [5,6,7], and enrollment in special education [6, 8]. Furthermore, children and adolescents born SGA at term are more likely to report attentional difficulties [4, 9] and symptoms of anxiety and depression [10].
Can SGA babies grow tall
Children born SGA are shorter during childhood and as adults, reaching adult heights that on average are approximately 1 sd lower than the mean (5, 6). The typical infant born SGA experiences a period of accelerated linear growth during the first 12 months of life that results in a stature above −2 sd in up to 90%.
When should I deliver my SGA baby
The optimal gestation to deliver the SGA fetus
Even when venous Doppler is normal, delivery is recommended by 32 weeks of gestation and should be considered between 30-32 weeks of gestation. If MCA Doppler is abnormal, delivery should be recommended no later than 37 weeks of gestation.
Should I be worried if my baby is measuring small
Many babies are otherwise healthy except for being small, so it is likely safe to try vaginal delivery. Babies that are severely growth restricted or that have abnormal Doppler patterns may not do well with labor, so C-section may be indicated. A discussion with your doctor is always recommended.
Should I worry if baby head circumference is small
When to see a doctor. Chances are your health care provider will detect microcephaly at your baby's birth or at a regular well-baby checkup. However, if you think your baby's head is small for the baby's age and sex or isn't growing as it should, talk to your provider.
Why is my baby’s head measuring small at ultrasound
Microcephaly is a condition where a baby's head is much smaller than expected. During pregnancy, a baby's head grows because the baby's brain grows. Microcephaly can occur because a baby's brain has not developed properly during pregnancy or has stopped growing after birth, which results in a smaller head size.
Should SGA babies be induced
In the SGA fetus with normal umbilical artery Doppler or with abnormal umbilical artery pulsatility index but end-diastolic velocities present, induction of labour can be offered but rates of emergency caesarean section are increased and continuous fetal heart rate monitoring is recommended from the onset of uterine …
What is the survival rate of a baby with SGA
The crude mortality rate per 10,000 person-years was 5.32 in children born with severe SGA, 2.76 in children born with moderate SGA, and 1.93 in non-SGA children.
Do low percentile babies catch up
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.
What is the risk of stillbirth with SGA
The cumulative risk of stillbirth rose from 28/10,000 ongoing SGA pregnancies at 37 weeks to 77/10,000 at 39 weeks (RR, 2.75; 95% CI, 1.79-4.2). Among pregnancies complicated by SGA <5% the cumulative risk of stillbirth at 38 weeks was significantly greater than the risk at 37 weeks (RR, 2.3; 95% CI, 1.4-3.8).
What if my baby’s head is measuring small
Microcephaly is a condition where a baby's head is much smaller than expected. During pregnancy, a baby's head grows because the baby's brain grows. Microcephaly can occur because a baby's brain has not developed properly during pregnancy or has stopped growing after birth, which results in a smaller head size.
What percentile is too small for baby
What does it mean to be small for gestational age Small for gestational age is a term used to describe babies who are smaller than usual for the number of weeks of pregnancy. These babies have birth weight below the 10th percentile.
Why is my baby head measuring small
Microcephaly is a condition where a baby's head is much smaller than expected. During pregnancy, a baby's head grows because the baby's brain grows. Microcephaly can occur because a baby's brain has not developed properly during pregnancy or has stopped growing after birth, which results in a smaller head size.
When is baby head size a concern
Technically, your child's head circumference (measurement around the widest part of their head) is greater than the 97th percentile. This means their head is larger than 97% of children of the same age and sex. Macrocephaly can be a sign of a condition that requires treatment.
Can ultrasounds be wrong about head size
Measures of accuracy and various factors which affect the accuracy are analyzed. Results: Ultrasonographic HC underestimated actual postnatal HC in 87.5% and overestimated actual HC in 12.5%. Sonographic underestimation of HC persisted throughout gestation and became more pronounced as gestational age increased.
When is the best time to deliver a SGA baby
The optimal gestation to deliver the SGA fetus
Even when venous Doppler is normal, delivery is recommended by 32 weeks of gestation and should be considered between 30-32 weeks of gestation. If MCA Doppler is abnormal, delivery should be recommended no later than 37 weeks of gestation.
When should I be concerned about my baby’s head size
The simple definition of the word macrocephaly is "large head." Doctors apply that diagnosis when a baby's head size is in the 98th percentile. This means that the baby's head is bigger than 98% percent of other babies of the same age. Sometimes, doctors detect macrocephaly during an ultrasound before the baby is born.
What percentiles are failure to thrive
Failure to thrive is defined as decelerated or arrested physical growth (height and weight measurements fall below the third or fifth percentile, or a downward change in growth across two major growth percentiles) and is associated with abnormal growth and development.
What week is stillbirth most common
At or after 40 weeks, the risk of stillbirth increases, especially for women 35 or older. Their risk, research shows, is doubled from 39 weeks to 40 and is more than six times as high at 42 weeks.
