What the Yuck: Should my breasts get bigger during PMS?

Too embarrassed to ask your doctor about sex, body quirks, or the latest celeb health fad? In a regular feature and a new book, "What the Yuck?!," Health magazine medical editor Dr. Roshini Raj tackles your most personal and provocative questions. Send 'em to Dr. Raj at whattheyuck@health.com.

Q: Is it normal for my boobs to get a whole cup-size bigger during PMS? It's such a dramatic change that I need two different sets of bras!

Yes, breast inflation is completely normal. During the premenstrual phase, we have higher levels of the hormones progesterone and prolactin, both of which can cause breast tissue to swell and milk glands to increase in size.

Plus, our bodies retain water during that premenstrual period. The change in boob size varies from woman to woman and sometimes from month to month. Some women won't notice much difference in their ta-tas, while others get a monthly (temporary) boob job.

Though you can't stop this hormonal process, there are things you can do to make your PMS breast makeover less pronounced. To keep water retention in check, cut back on your salt intake. Keep an eye out for hidden sodium in soup, vegetable juice, and fast food. If that doesn't help, water pills can help with the water retention.

If the change is dramatic and it really stresses you out, talk to your doctor about going on oral contraceptives. By regulating the hormonal fluctuation, the Pill can help keep you in one cup-size all month long.

    PMS has nothing to do with it. Nature does. That's why some of us develop large boobs early in life.Marcy

    We live in a culture where we are surrounded by images of what is considered beautiful, and especially in the United States, part of our beauty standard includes large, full breasts. For those of us who don’t have them, we are reminded daily of what we’re missing out on. It’s not just our modern society that values bigger breasts though. Large breasts and curves have always been seen as sexy and more desirable, making women who don’t have those attributes seem less feminine or less attractive..
