The main active ingredients in contraceptive pills are female hormones and progestins, both of which belong to the steroid (lipid-soluble) hormone category.
A small amount of female hormones (such as those used in hormone replacement therapy for menopausal women) can lower blood lipid levels; however, the components of contraceptive pills are typically in high doses (to effectively suppress ovulation).
This makes them contraindicated for patients with cardiovascular issues.
Additionally, smoking is detrimental to respiratory and cardiovascular function, with the severity of its effects related to the quantity smoked and individual health conditions.
The level of risk is not uniform for everyone.
Other contraindications for contraceptive pills include: individuals with vomiting, heart disease, severe diabetes, cerebrovascular disorders, and those with thrombosis or phlebitis.

Yes, smoking women are indeed at a higher risk when it comes to using birth control pills, and there are several reasons for this. The primary concern is related to the increased risk of cardiovascular complications associated with both smoking and hormonal contraceptives.

Birth control pills typically contain synthetic forms of estrogen and progestin, which are hormones that can affect blood clotting and vascular health. When a woman smokes, the harmful substances in cigarettes can damage the blood vessels and increase the likelihood of blood clots. The combination of smoking and taking hormonal contraceptives can significantly elevate the risk of serious cardiovascular events, such as deep vein thrombosis (DVT), pulmonary embolism, stroke, and heart attack.

The risk is particularly pronounced in women over the age of 35 who smoke more than 15 cigarettes a day. For these women, the risk of developing blood clots is substantially higher than in non-smokers. This is why healthcare providers often advise against the use of hormonal contraceptives in women who smoke, especially those who fall into this higher-risk category.

In addition to cardiovascular risks, smoking can also have other negative effects on reproductive health. It can lead to reduced fertility, complications during pregnancy, and adverse outcomes for the baby, such as low birth weight and preterm birth. Therefore, if a woman is considering pregnancy or is already pregnant, it is crucial to quit smoking not only for her health but also for the health of her future child.

Moreover, the interaction between smoking and hormonal contraceptives can exacerbate other health issues. For instance, women with pre-existing conditions such as hypertension, diabetes, or a history of migraines may face even greater risks when combining smoking with birth control pills.
For women who are smokers and are considering using birth control pills, it is essential to have a thorough discussion with a healthcare provider. They can provide personalized advice and may suggest alternative contraceptive methods that do not carry the same risks, such as non-hormonal options like copper IUDs or barrier methods.

In summary, smoking significantly increases the risks associated with hormonal contraceptives, particularly regarding cardiovascular health. Women who smoke should be cautious and consult with healthcare professionals to explore safer contraceptive options and to discuss strategies for quitting smoking, especially if they are planning to conceive in the near future. Quitting smoking not only reduces the risks associated with birth control but also enhances overall health and well-being, paving the way for a healthier pregnancy and baby.
