DURHAM, N.C. In a finding that confirms what many obstetricians and gynecologists suspected, Duke University researchers report that younger women who undergo hysterectomies face a nearly two-fold increased risk for developing menopause early.
The study, published in the December issue of the journal Obstetrics & Gynecology, is the largest analysis to track over time the actual hormonal impact of woman who had hysterectomies and compare them to women whose uteruses remained intact.
"Hysterectomy is a common treatment for many conditions, including fibroids and excessive bleeding," said Patricia G. Moorman, PhD., MSPH, an associate professor in the Department of Community and Family Medicine at Duke University and lead author of the study. "Most women are very satisfied with the results of a hysterectomy. But this is a potential risk of the surgery that should be considered along with the benefit."
Up to 600,000 women in the United States undergo hysterectomy each year, but the long-term consequences of the procedure have not been well documented. Studies have been small, or relied on the recollections of women about the onset of menopause.
The Duke team enrolled nearly 900 women ages 30 to 47 at two hospitals in Durham, N.C. -- Duke University Medical Center and Durham Regional Hospital and followed up with blood tests and questionnaires for five years. Half the women, 465, were healthy controls who had no surgery, while 406 women underwent hysterectomies that spared at least one ovary.
Preserving the ovaries while removing the uterus is a strategy designed to allow a woman's hormone production to continue, which has health benefits. Moorman said doctors have long known that early menopause either from surgery or from other factors that halt egg production can increase a woman's risk of osteoporosis, heart disease and other ailments.
Yet despite preserving the ovaries, the Duke team found that 14
