(NEW YORK) — Abby and Brittany Hensel are close — very close. They may have two separate brains, hearts and sets of lungs, but they share everything else, including, as they say, “a normal life … whatever that is.”
The 22-year-olds from rural Minnesota are identical conjoined twins and their physiology has never stood in the way. There are compromises that have to be made — Abby controls the right side of the body and Brittany the left — but they move with remarkable ease, riding a bike, dancing at parties and even driving a car.
Their updated story, Abby & Brittany, told in documentary form when they were 12 and again at 16, will air Tuesday, Sept. 28, at 10 p.m. on TLC.
When the twins were born in 1990, their parents were told the babies might not survive the night. But by age 6, they were appearing on Oprah and the cover of Life magazine.
“People have been curious about us since we were born, for obvious reasons,” say the twins in the first episode of the eight-week series. “But our parents never let us use that as an excuse. We were raised to believe we could do anything we wanted to do.”
“The most amazing thing about us is we are like everyone else,” they chime together.
The TLC docu-series follows the women’s social lives as they prepare to graduate from Minnesota’s Bethel College and embark on travel to Europe searching for a teaching job.
Conjoined twins occur once out of every 200,000 live births, according to the University of Maryland Medical Center, but about 40 to 60 percent of them are stillborn and only about 35 percent survive one day.
Girls seem to do better medically. About 70 percent of conjoined twins who survive are female.
Conjoined twins are genetically identical, and are, therefore, always the same sex. They develop from the same fertilized egg, and they share the same amniotic cavity and placenta.
“All conjoined twinning is really uncommon,” says Dr. Christopher Moir, a pediatric surgeon and medical director at the Mayo Clinic’s Children’s Center. “But the chance of a mother delivering a set of conjoined twins and their surviving is one in a million.”
Conjoining occurs in the earliest weeks of gestation, according to Moir, “sometimes before the mother even knows she is pregnant.”
There are no genetic or environmental influences that cause conjoining, he says, “just a happy accident of embryos.”
