Contrary to speculation, the new generation of birth control pills currently on the market do increase the risk of gall bladder disease, but only marginally, a new report published in the Canadian Medical Association Journal reveals.
Researchers at the Vancouver Coastal Health Research Institute said that the risk of gall bladder disease is the same for all birth control pills in spite of the fear that some of the newer pills pose a greater risk.
The researchers analyzed more than 2.7 million women who used birth control pills for at least six months during 1997 and 2009 and found that roughly over 27,000 underwent a surgical gall bladder removal procedure known as cholecystectomy.
On testing whether the risk of gall bladder increased with different forms of pills, the researchers analyzed seven different forms of pills and found that while some of the newer generation pills such as Yaz and Yasmin did pose a highest risk, it was not significant to clinically affect the user.
"Statistically, there is a slightly higher risk to women using an oral contraceptive containing drospirenone but, in the grand scheme of things, we don't think it's clinically significant", lead researcher Dr Mahyar Etminan said.
