do synthetic hormones, as in those used in birth control pills, don't affect the body and do the same thing as the natural hormone?

However, for some women, birth control pills and patches can increase their blood pressure. Those extra hormones can also put you at risk for blood clots. Being overweight is also considered a risk factor for high blood pressure, heart disease, and diabetes. The kinds of birth control that work the best to prevent pregnancy are the implant and IUDs - they're also the most convenient to use, and the most foolproof. Other birth control methods, like the pill, ring, patch, and shot, are also really good at preventing pregnancy if you use them perfectly.
