(CNN) -- Divorce causes more than bitterness and broken hearts. The trauma of a split can leave long-lasting effects on mental and physical health that remarriage might not repair, according to research released this week.
Research shows health differences between people who are married and those who have gone through a divorce.
"People who lose a marriage take such damage to their health," said Linda Waite, a sociologist at the University of Chicago in Illinois.
Waite and co-author Mary Elizabeth Hughes, of Johns Hopkins Bloomberg School of Public Health, found that divorced or widowed people have 20 percent more chronic health conditions such as heart disease, diabetes or cancer than married people. They also have 23 percent more mobility limitations, such as trouble climbing stairs or walking a block.
