What is premenstrual syndrome?

Emotional disturbanc: The specific emotional and physical symptoms attributable to premenstrual syndrome or PMS vary from woman to woman, but each individual woman's pattern of symptoms is predictable, occurs consistently during the ten days prior to menses, and vanishes either shortly before or shortly after the start of menstrual flow. In particular, emotional symptoms must be present consistently to diagnose pms.

PMS: Premenstrual syndrome (pms) has a number of symptoms that include mood swings, food cravings, fatigue, irritability, depression and breast tenderness. The majority menstruating women, perhaps 75%, experience some form of premenstrual syndrome. Symptoms tend to recur in a predictable pattern and tend to peak during the late 20s and early 30s.
