Heard the one about how the Pill will make you pudgy? Not true! “Whether you gain or lose weight over time has nothing to do with the Pill,” says Dr. Allen. Studies have shown that some women who use hormonal contraceptives put on pounds—while some actually lose weight! The trick, of course, is to find the method that works for you, which will likely mean experimenting with your doctor’s help.
If you’re already overweight, however, you should consider this: Contraceptives that contain estrogen may increase health risks for obese women who have long-term diabetes or uncontrolled high blood pressure. And at least one contraceptive, the transdermal patch (Ortho Evra), has been found to be less effective in women who weigh more than 198 pounds.
