Intrauterine growth restriction (IUGR), or fetal growth restriction, is the poor growth of a fetus while in the womb during pregnancy. IUGR is defined by clinical features of malnutrition and evidence of reduced growth regardless of an infant's birth weight percentile. [ 5 ]
If small for gestational age babies have been the subject of intrauterine growth restriction, formerly known as intrauterine growth retardation, [5] the term "SGA associated with intrauterine growth restriction" is used. Intrauterine growth restriction refers to a condition in which a fetus is unable to achieve its genetically determined ...
There is much variation in the growth of the human fetus. When the fetal size is less than expected, the condition is known as intrauterine growth restriction also called fetal growth restriction; factors affecting fetal growth can be maternal, placental, or fetal. [18]
These criteria are divided into physical and neurological criteria. This scoring allows for the estimation of age in the range of 26 weeks to 44 weeks. The New Ballard Score is an extension of the above to include extremely pre-term babies, i.e., up to 20 weeks.
An impaired placenta cannot support the pregnancy and this may lead to the loss of a chromosomally normal baby. [5] On the other hand, an apparently normal diploid fetus may experience problems with growth or development due to the effects of uniparental disomy (UPD). Intrauterine growth restriction (IUGR) has been reported in a number of CPM ...

Drug use will influence extreme irritability, crying, and risk for SIDS once the fetus is born. [39] Marijuana will slow the fetal growth rate and can result in premature delivery. It can also lead to low birth weight, a shortened gestational period and complications in delivery. [38]
Fetal distress, also known as non-reassuring fetal status, is a condition during pregnancy or labor in which the fetus shows signs of inadequate oxygenation. [1] Due to its imprecision, the term "fetal distress" has fallen out of use in American obstetrics. [2] [1] [3] The term "non-reassuring fetal status" has largely replaced it. [4]
