A new study reveals that mothers who have recently given birth to twins are at a higher risk of heart disease in the following weeks and months. Researchers reported in the European Heart Journal that within the first year after giving birth to twins, women face a doubled risk of being hospitalized due to heart problems. According to the researchers, this risk increases even more — up to eight times — when high blood pressure is experienced during pregnancy. Dr. Ruby Lin, a medicine researcher at Rutgers Robert Wood Johnson Medical School in New Jersey, stated in a press release that a mother’s heart works harder during pregnancy with twins compared to other mothers. The lead researcher further explained that it may take weeks for these mothers to recover after the birth of twins.
