Multiple Births Clinical Presentation
- Author: Garth E Fletcher, MD; Chief Editor: Ted Rosenkrantz, MD more...
History
- Most multifetal pregnancies are prenatally diagnosed.
- Maternal complaints of excessive weight gain, hyperemesis gravidarum, the sensation of more than one moving fetus, use of ovulation-inducing drugs, or family history of dizygotic twins should alert caregivers to the possibility of a multifetal pregnancy.
Physical
- Women with multifetal pregnancies may have a uterine size that is inconsistently large for dates and may experience accelerated weight gain.
- Upon auscultation, more than one fetal heart rate may be heard.
Causes
- Risk factors for multifetal pregnancy can be divided into natural and induced.
- Risk factors for natural multifetal pregnancy include advanced maternal age, family history of dizygotic twins, and race.
- Induced multifetal pregnancies occur following infertility treatment via the use of ovulation-inducing agents or gamete/zygote transfer.
