The Society for Maternal-Fetal Medicine says it can come from many mother, baby and placenta conditions, happens in up to 10% of pregnancies and is a leading cause of illness and death in infants. It is found by ultrasound. The Society defines it as an estimated fetal weight, or an abdominal circumference, below the 10th percentile for the gestational age, so a growth chart sets the line, and the available charts do not agree on who is small.",
  "summary_technical": "Condition of the fetus (recipient fetal). Source: Society for Maternal-Fetal Medicine Consult Series #52 (abstract on PubMed). The consult says published diagnostic criteria are disparate, detection rates relatively low and prevention and treatment options limited. It recommends serial umbilical artery Doppler once growth restriction is diagnosed. Trials of delivery timing are filed as the TRUFFLE and DIGITAT study records. Growth restriction is one route to low birth weight; the two are not the same thing.",
