Researchers at the New York-Presbyterian Hospital/Columbia University Medical Center have recently completed a study on birth control effectiveness in overweight and obese women. They found there's nothing to worry about! 150 women of all sizes on both high dose and low dose oral contraceptives were followed. They had ultrasounds and blood tests to determine if their ovulation was suppressed. 3 of the 96 "normal weight" women ovulated, and 1 of the 54 "overweight/obese" women ovulated. And, they found that a higher dose pill isn't any more effective than a low does pill in overweight women.
When taken at the same time everyday, women of all sizes should have a failure rate of only 0.3%. (Of course, most women use it with a more "carefree" attitude, raising the failure rate up to 8%!)
Overweight and obese women will now have the options whether to take higher dose or lower dose pill. They have nothing to worry because both pills have the same effect on their bodies.
