PMS

Fifteen years ago, doctors claimed that PMS did not exist.

Today, it's one of the most common conditions suffered by women, with symptoms that can be anything from mildly inconvenient to positively debilitating.

Admittedly, some women sail through their cycles without a mood swing or a hint of discomfort. But they are pretty rare.

PMS is estimated to affect 70-90% of women during their childbearing years.

30-40% of women are believed to have symptoms severe enough to interfere with their daily lives.
