Premenstrual Dysphoric Disorder (PMDD) Overview

Premenstrual dysphoric disorder (PMDD) is a particularly severe form of the premenstrual syndrome (PMS). Both PMS and PMDD cause disturbing symptoms during the second half, known as the luteal phase, of a woman's menstrual cycle. The symptoms tend to worsen over the week prior to the onset of the menstrual period and then improve within a few days after the period starts.

PMDD can cause a number of different symptoms, but fatigue, tiredness, mood changes, and bloating are common. About 3% to 8% of menstruating women are estimated to suffer from PMDD. In contrast to PMS, the symptoms of PMDD are severe enough to have a significant impact upon the woman's daily activities and functioning.

These women are considered to suffer from premenstrual dysphoric disorder (PMDD), an unusually severe form of PMS.

The symptoms of PMDD generally begin the week before menstruation and end a few days after menstruation has begun. Women with PMDD may experience drastic mood swings, anger, depression, irritability, tension, sleepand appetite changes, fatigue, and physical problems such as pain or bloating.
