A new study published in the British Medical Journal suggests that hormonal birth control products, including vaginal rings and skin patches, may increase the risk of blood clots, heart attacks, and strokes. The research found that women using contraceptives containing estrogen and progestin are more likely to experience these complications compared to those not using hormonal birth control.
According to Dr. Katie White, director of health systems with the Heart and Stroke Foundation of Canada, estrogen-based contraceptives can increase a woman’s risk of blood clots, which in turn can lead to heart attacks and strokes. Age is also a significant factor, with women over 35 being at a higher risk, especially if they have other risk factors such as smoking or high blood pressure.
The study found that the vaginal ring and skin patch were associated with the highest risk of blood clots, with the risk increasing by two- to three-fold. The combined estrogen-progestin pill was also linked to double the risk of stroke and heart attack. In contrast, progestin-only intrauterine devices (IUDs) were not associated with any cardiovascular risks.
The researchers used data from over 2 million women in Denmark aged 15-49 years and found that the use of hormonal contraceptives increased the risk of blood clots and cardiovascular diseases. However, it’s essential to note that these risks are still lower than those associated with pregnancy and the postpartum period.
Healthcare professionals should be aware of this potential risk when prescribing hormonal contraceptive methods, according to the authors. The Heart and Stroke Foundation of Canada advises women with congenital heart disease to discuss contraception options with a healthcare expert who specializes in their risk factors.
It’s also crucial to recognize the signs of stroke and blood clots, which can be spotted using the acronym FAST for stroke and chest pain, light-headedness, feeling out of breath, leg tenderness, and leg swelling for blood clots.
