In the weeks leading up to my IUD insertion a couple years ago, I remember interrogating many of the women in my life about their own experiences with birth control. This would be my first brush with synthetic hormones, since the prospect of experiencing side effects like acne, severe mood swings, and fatigue was enough for me to opt for other contraceptive options over the pill. But even though my ob-gyn insisted that the low dose in Mirena would prevent my body from going haywire, I was still anxious to know how, exactly, it would react.
While polling my peers, I learned above all else that women are extremely eager to chat about birth control and its purported side effects. One friend swore her IUD had made her lose a bra cup size, while another lamented that the pill had made her breasts larger. One woman I know with a characteristically flawless complexion experienced cystic acne for the first time in her life. Some cited mood changes, for better and for worse. But the topic that dominated most of our conversation—particularly for those of my peers who have a history with the pill—was bloating and weight gain.
This wasn't exactly surprising to me, as the correlation between the pill and weight was something I remember discussing in hushed tones with my friends in high school. It was a notion so persistent that even as a 24-year-old adult, I had accepted the fact that I might experience this symptom after getting my IUD, even if I ultimately decided that having peace of mind (and almost nonexistent periods) outweighed this possibility. Besides, the anecdotal evidence seemed to only confirm that this phenomenon was definitely a thing.
In the two years since getting my IUD—a decision I could not be happier about—things have come full circle: I am now one of the women my friends come to for advice when making their own choices about contraception. And still, that question about bloating and weight remains ever-popular—to the point that I finally (and, yes, belatedly) decided to get a professional opinion on the matter.
