Understanding Intrauterine Growth Restriction (IUGR): What You Need to Know

Question
I am 35 weeks pregnant and my last doctors visit my doctor let me know that there is a chance of intrauterine growth retardation. He is not wanting to tell me much and I feel it is because he does not want to scare me. I need upfront and honest info on this. Please help.

Answer
Intrauterine Growth Restriction (IUGR) is a situation where the estimated fetal weight by sonogram falls below the tenth percentile for gestational age. (We used to call this intrauterine growth retardation, but the new term is restriction). The majority of these fetuses are simply constitutionally small. The incidence of pathologic IUGR varies according to the population under investigation. If the sonogram had any suspicion of IUGR, another sonogram will be done in another week (along with a biophysical profile) and, if all is normal, you can proceed to term and wait for the onset of labor. However, if there is any evidence of a "lag" in the growth of the baby in one week, your doctors may decide to induce your labor, because it may be better to deliver the baby. If there is any doubts after you reach 36 weeks gestation, it may be safer to deliver the baby at that time, as well.
