Doctors often implant multiple embryos into surrogates in order to improve the chance of a pregnancy. Too often, however, this results in the surrogate becoming pregnant with multiple babies at once. While many see this as a blessing, being pregnant with multiples puts women at risk for several conditions such as high blood pressure, anemia, hemorrhaging, and preeclampsia. Lahl adds that it also makes the delivery more difficult.
"These women end up in the hospital early, trying to keep the babies in the womb longer," she says. "The babies are then born premature and have to stay in the hospital longer."
