April 6, 2005 -- One of the most common causes of female infertility -- polycystic ovary syndrome (PCOS) -- may raise the risk of heart disease.
PCOS is a hormone imbalance that interferes with women's normal ovulation. Nearly 2 million U.S. women could be affected, say doctors from the Medical College of Virginia in The Journal of Clinical Endocrinology & Metabolism. These women have increased rates of metabolic syndrome, they find.
"These findings support the idea that PCOS should be considered a general health disorder with serious public health implications," they write. They encourage doctors to screen PCOS patients for metabolic syndrome, a cluster of abnormalities that raises the risk of heart disease and diabetes.
The study of 106 women with PCOS showed that 43% also had metabolic syndrome. Metabolic syndrome was twice as common in these women as in women of the same age without PCOS, says the study.
Because PCOS affects up to 10% of the 50 million reproductive-aged women in the United States, if the prevalence of metabolic syndrome in PCOS is approximately 40%, then nearly 2 million women may be affected with both PCOS and the metabolic syndrome, write the researchers.
Symptoms of PCOS
Symptoms of PCOS include:
PCOS can start gradually. Many women (but not all) will have numerous small cysts on their ovaries. Some women have other symptoms but do not have evidence of ovarian cysts.
To diagnose PCOS, doctors look at many possible causes of excess and abnormal production of male hormones. Medications and lifestyle adjustments, such as weight loss in overweight women, are usually used to treat the metabolic problems associated with PCOS.
Insulin resistance is the hallmark of PCOS, say the researchers. The body makes insulin to control blood sugar.
