Birth control pills may clog your blood vessels
Long term use of oral contraceptives can increase your risk for heart disease. A study conducted at the Ghent University in Belgium suggests that birth control pill use can lead to the formation of potentially dangerous plaques in the key blood vessels. These can further lead to formation of blood clots and can compromise the blood flow to important organs such as heart or brain, causing a heart attack or stroke.
The research conducted on 1301 women aged 35 to 55 found that for every decade of pill use, the plaque increases at the rate of 20-30%. The scientists suggest that there is no need to abruptly stop the use of the pill, as more research needs to be done on this.
The bottom line is that if you intend to take birth control pills, you have to take care of your other risk factors for heart disease such as blood pressure, cholesterol and smoking.
