Wasn't it already known that hormone-replacement therapy, when administered for more than a couple of years, was a bad idea...
Even young women can experience SUI after childbirth, but the problem rarely becomes chronic until much later, often around menopause.

...higher stroke risk was comparable to what researchers had seen for the estrogen-progestin combo. Even at that, the increase was rather slight--about 8 additional strokes per 10,000 women. "Women should not feel this is some grand emergency for them," says Dr. Barbara Alving, director...
