Birth control pills increase the risk of heart problems in women who have certain heart disease risk factors, including women who smoke, or have high blood pressure or diabetes


The hormones in birth control pills can raise blood pressure—have your blood pressure checked at least once a year if you use the pill or the patch


If you develop high blood pressure while on the pill, you may need to switch to another form of contraception.

In women with certain heart disease risk factors, taking birth control pills can increase the risk of heart problems. You may want to consider an alternative method of birth control if you:


Smoke


Have high blood pressure


Are overweight or obese


Have diabetes


Have been diagnosed with heart disease, stroke, or blood clots


Have a family history of heart disease

Women who smoke while using oral contraceptives have a higher risk of serious cardiovascular problems such as blood clots, particularly if they are older than 35 years of age.

Blood sugar levels sometimes change dramatically in women who take birth control pills. If you are diabetic or have a close relative who is, you should have your blood sugar monitored closely when starting the pill.

If you have had problems with blood clots, a heart attack, or a stroke, or if you have had any kind of cardiovascular disease, hormonal contraceptives may not be a safe option for you. Be sure to discuss your medical history with your healthcare provider, including whether you have taken high-dose birth control pills in the past, before taking hormonal contraceptives
