When Does Premenstrual Dysphoric Disorder Start?

Symptoms of PMDD appear during the week before menstruation and end within a few days after your period starts. These symptoms disrupt daily living tasks. Symptoms of PMDD are so severe that women have trouble functioning at home, at work, and in relationships during this time.

How early can PMDD start?

Dysphoria is derived from the Greek word dusphoros, which means hard to bear. The symptoms of PMDD are recurrent. They usually start seven to 10 days before menstruation and decrease within a few days of the onset of menstrual flow.

What triggers PMDD?

What causes PMDD? Experts don't know why some women get PMDD. Decreasing levels of estrogen and progesterone hormones after ovulation and before menstruation may trigger symptoms. Serotonin, a brain chemical that regulates mood, hunger and sleep, may also play a role.
