New Birth Control Pills May Increase Blood Clot Risk in Women
If you have been on the newer forms of birth control pills, STOP! It has been found in a study that birth control pills of brands like Desogen, Yaz, and Yasmin are likely to cause unwanted blood clots. The older pills had no such issues. However, lead researchers of the study also stated that the clot that occurs due to birth control pills is likely in fewer women and is less likely than the risk of blood clot in pregnant women. In this context, Dr. Mamta Mamik, obstetrician and gynecology said, “One has to weigh the benefits of using oral contraceptive pills against the risks, such as unwanted pregnancies and abnormal uterine bleeding with resultant anemia.”
The study team was headed by Yana Vinogradova, University of Nottingham analyzed two large database of UK patients. For the study, the rsearchers looked into the risk of blood clotting in women between the age of 15 and 49. The results have been based on the use of birth control pills by women of the group.
The researchers specifically found out that women who were on birth control pills that contain newer types of progesterone hormones like desogestrel, drospirenone, cyproterone, and gestodene, are more likely to develop problems of blood clots by 1.5 to 1.8 percent. This was compared to the risk of blood clot in women who used older forms of progesterone like levonorgestrel, norgestimate, and norethisterone. It was concluded that older forms of birth control pills are far better than the newer ones when both the types are compared. However, the risk of blood clot is only in fewer women and may not be a major risk. The study did not deal with the cause-effect relation of the newer birth control pills and blood clotting problem. The study further compared the health conditions of women who have never taken a birth control pill and women who have been taking the newer types of birth control pills. The women who took newer types of birth control pills are about four times more probable to develop clots and women who took the older pills are just 2.5 times probable to result in blood clots. These findings are based on the study by the researchers.
The number of blood clot patients per year, per 10, 000 women is just six and is considerably low as compared to 14 of the women who took newer birth control pills containing desogestrel and cyproterone. So, whether the use of newer birth control pills in preventing pregnancy is still a matter of research and study. And, the Vinogradova’s team of researchers stressed that the birth control pills are safe and effective for women. According to the team, the threefold increase in the chance of blood clot is still low in women as compared to 10 percent of the risk in pregnant women. The researchers are further delving into the cause-effect factors of the findings and are soon to come with newer developments.
The researchers concluded that when prescribing birth control pills, doctors should consider the findings of the study. If the doctors find any symptoms of blood clotting or poor circulation in the body, they should switch to other formulations immediately.
