Does Yaz Make You Gain Weight?

Yaz® (drospirenone/ethinyl estradiol) is a birth control pill that is also used to treat premenstrual dysphoric disorder (PMDD) and acne. Many women may wonder, "Will I gain weight on Yaz?"
It has long been thought that birth control pills contribute to weight gain. Many women will not take birth control pills because they are afraid they will gain weight.
However, recent data suggests that birth control pills probably do not cause weight gain. Although women taking them often gain weight, this is likely not caused by birth control pills. In studies, there were no significant differences in weight gain between women who took birth control pills and those who did not.
In some studies, weight gain was a common Yaz side effect. However, it is difficult to determine whether weight gain in women using the drug was more frequent than weight gain in similar women not using it. If you think the pill is causing you to gain weight, talk to your healthcare provider. He or she can give you suggestions for dealing with any weight gain or suggest another method of birth control.
