Premenstrual Syndrome (PMS)

About 75 percent of women have certain symptoms a few days before [menstruation].

These include mood swings, fatigue, irritability, depressive mood or abdominal pain. If these complaints interfere with the regular daily routine or their activities, we speak of premenstrual syndrome.

Typischerweise verschwinden diese Beschwerden zu Beginn des nachfolgenden Zyklus wieder.
