PMS in the workplace. An occupational health nurse's guide to premenstrual syndrome.

1. Premenstrual syndrome (PMS) is defined as the cyclic recurrence of physical, psychological, or behavioral symptoms that appear after ovulation and resolve with the onset of menstruation. These symptoms can be severe enough to disrupt personal relationships, social activities, or job performance. 2. The exact cause of PMS is unknown. The best tool to diagnose PMS is a daily symptoms rating calendar. To have the diagnosis of PMS, the symptoms must be severe enough to disrupt normal daily activities. 3. The occupational health nurse can provide information about first line treatment modalities for PMS symptoms including dietary modifications, nutritional supplements, aerobic exercise, and stress management skills. 4. More research is needed about PMS in the workplace and the effect of treatments on outcomes such as job attendance and work performance.
