Venous Thrombosis Due to Contraceptives
The use of hormonal contraceptives is increasingly widespread as a method of preventing pregnancy. They’re safe for the most part; however, some data reveals that women who use them have a greater risk of venous thrombosis.
Based on the external administration of sex hormones to the body, hormonal contraceptives help prevent pregnancy. Receiving these hormones prevents ovulation in each woman’s menstrual cycle.
In addition, they also thicken the vaginal mucus, making it very difficult for sperm to pass through. They’re effective when used accordingly.
What are hormonal contraceptives?
Firstly, there are many different types of hormonal contraceptives, among them:
- Oral. That is, in the form of contraceptive pills.
- Hormonal IUD. This is a device inserted into a woman’s cervix that releases hormones and can remain there for years.
- Patch. This is an adhesive cloth that sticks to the skin and releases hormones through it.
- Vaginal ring. This device goes is placed inside the vagina during each menstrual cycle and releases hormones.
- Hormonal implant. This is a capsule placed under the skin and can stay there for years, it releases hormones in each cycle.
As these aren’t barrier contraceptive methods, we must remember they don’t protect against sexually transmitted diseases, only pregnancy. Those with an active sexual life with people they’ve just met should use condoms for protection.

What’s venous thrombosis?
It’s the formation of a blood clot in the deep veins of the body and it often occurs in the legs. A clot can travel through the bloodstream until it becomes stagnant in a smaller-sized vessel and interferes with the normal blood circulation.
When this clot travels to the lungs, an embolus, the result will be a pulmonary embolism. This is a very serious situation and has a high rate of mortality in those who suffer from it.
There are many risk factors for developing venous thrombosis. Some of the most prominent are obesity and, frequently, immobilization.
Thus, after an operation in which you must remain prostrate, or in the case of very long trips, you must take the necessary precautions to prevent venous thrombosis. In addition, other risk factors are smoking and pregnancy.

The risk of venous thrombosis due to hormonal contraceptives
Estrogens, a key component of hormonal contraceptives, appear to cause blood clotting. This is why, in the face of prolonged exposure and after taking high levels of these hormones, the risk of altered coagulation and thrombus formation increases.
Estimates indicate that the risk of suffering a thrombosis after taking contraceptives is for one in every 100,000 women.
It may seem a low risk but you must keep in mind that the victims are usually young and previously healthy women. Also, there are millions of contraceptive users around the world. Thus, keep this in mind when choosing this type of contraceptive.
Still, not all hormonal contraceptives are made the same. Increasingly, contraceptives contain a lower dose of estrogen. Thus, it minimizes this and other risks that these hormones may pose.
Hormonal contraception is still safe
Finally, hormonal contraceptives remain a very safe method for preventing pregnancy. Their widespread use and advances in pharmacological development mean they carry fewer and fewer risks as time goes by. However, keep in mind there are always side effects.
Therefore, professionals recommend that you consult your doctor before using any type of contraceptive. Only they can evaluate your case, determine any possible risk factors, and advise the safest format and composition for you.
