As per a new study, women who have been diagnosed with Polycystic Ovary Syndrome (PCOS) and who also consume birth control bills increase the risk of blood clots by two times in comparison to women who consume pills.
Dr.Christopher McCartney, who is an associate professor at the University of Virginia School of Medicine in Charlottesville said:,
"for many women with PCOS, (the risks) will be small. For some women, they might be high enough to say we really shouldn't use the Pill, such as for women over 35 who smoke".
Hormone imbalance is detected in women with PCOS who constitute three to five percent of the population. These women suffer from extra hair growth, irregular periods and are at increased risk for obesity, hypertension and diabetes. These women are usually treated by using oral contraceptives. Most pills carry the warning for blood clots on them.
Venous thromboembolism is the other name for blood clot and is a dangerous condition if it extends to the lungs. But the cases of study did not show any such symptoms. Researchers want to know if women with PCOS, for whom already risk of heart disease is prevalent, will also have any increased risk with pills.
The study was conducted with the help of a health insurance database on 43,500 women who were diagnosed with PCOS. Almost double the rate of women with PCOS consuming pills showed blood clots.
The study, which was published in the Journal of Canadian Medical Association could not explain the reason for women with PCOS suffering from blood clots. McCartney suspects that obesity may be the cause for these symptoms. When this study was started in 2001, the percentage of women with and without PCOs was similar. But in 2009 when the study was concluded, women with PCOS became 33 percent.
"weight not only contributes to the risks associated with the Pill, it also contributes to some of the symptoms of PCOS and some of the metabolic problems associated with PCOS".
The lead author of the study, Steven Bird said:
"Although the risk is small, prescribers should consider the increased risk for blood clots in women with PCOS who are prescribed contraceptive therapy".
