So what is the difference between SGA and IUGR?
SGA=infant whose weight is lower than the population norms. weight is below 10th percentile for gestational age
cause can be pathologic or nonpathologic
IURG=failure of normal fetal growth caused by multiple adverse affects on fetus
due to process that inhibits normal growth potential of fetus.

What is the difference between the terms "small for gestational age" and "intrauterine growth restriction." The only thing I could find is that SGA is much more precise (weight is below the 10th percentile for gestational age), and IUGR is more of an umbrella term: "Failure of a fetus to grow as expected for gestational age because of maternal, placental, or fetal factors." I know the terms are often used interchangeably, but is there any practical distinction? Thanks for any light you can shed on this subject for me :kiss
