Does NuvaRing Make You Gain Weight?

Many forms of birth control are known to cause weight gain, but do they make you gain weight? NuvaRing® (etonogestrel/ethinyl estradiol vaginal ring) is a hormonal birth control method, similar to the birth control pill (except that it is a flexible ring that is inserted vaginally once a month). As with most hormonal contraceptives, it's possible to gain weight while taking the medication.
It has long been thought that hormonal contraceptive pills contribute to weight gain. However, recent data suggests that this may not actually be the case. Although women taking birth control pills often gain weight, it appears that this weight gain is probably not caused by birth control pills.
It is not known whether this information applies to NuvaRing. However, it is reasonable to assume that it does, since NuvaRing acts just like birth control pills (and contains similar hormones). In some studies, weight gain was a common NuvaRing side effect. However, it is difficult to determine whether weight gain in women using NuvaRing was more frequent than weight gain in similar women not using this form of birth control.
