Use of oral contraceptives (OC) containing ethinyl estradiol significantly reduces whole-body insulin sensitivity in young healthy women.

If you take birth control pills, be aware that the estrogen in them can make your body less sensitive to insulin by about 40% compared to women not on pills. This doesn't mean you will get diabetes, but it is a factor to consider if you have other risk factors.
