Twin moms' hearts are working harder during pregnancy
With that extra weight gain and extra load up front, moms who are expecting twins may feel slower and heavier, and their center of gravity may be more dramatically off-kilter. In addition, Dr. Rosenn says blood volume can increase by up to 70% during a twin pregnancy. “This means your heart is working harder; it almost feels like you’re exercising,” Dr. Rosenn explains. “It is a bigger physical burden in more than one way... Very often, women feel they can’t work as much, and may cut their work hours around six or seven months.” The doctor says a mom-to-be may find it difficult to climb stairs, fall asleep, and do a number of other tasks, so she needs to listen to her body about how much rest feels warranted.
