Harvard researchers have discovered that women who suffer miscarriages are more likely to die before the age of 70. In a new study published in the British Medical Journal, they followed over 100,000 nurses over a 24-year period. About one quarter of them had at least one pregnancy ending in miscarriage during that time. The researchers found that the women who miscarried had almost a 20 percent higher chance of dying before their 70th birthday, particularly from cardiovascular disease and cancer. The association between miscarriage and early death was particularly strong for younger mothers who had a miscarriage or repeat miscarriages. The researchers believe that miscarriage could be a marker of future health risk, as women with a history of miscarriage have a higher risk of high blood pressure, cardiovascular diseases, and Type 2 diabetes.
