Causes, incidence, and risk factors

An exact cause of PMS has not been identified. However, it may be related to social, cultural, biological, and psychological factors.

PMS is estimated to affect up to 75% of women during their childbearing years.

It occurs more often in women:

• Between their late 20s and early 40s
• Who have at least one child
