PMDD symptoms include severe emotional changes
In addition to PMS symptoms, PMDD includes one or more of the following:
- Feeling overwhelmed, out of control or on edge
- Increased sensitivity to conflict and rejection
- Lasting irritability
- Severe depression (feelings of hopelessness, worthlessness, guilt or despair)
- Severe mood swings
The causes of PMS and PMDD aren’t fully understood
PMS and PMDD have been linked to hormone changes that occur during the menstrual cycle, but they do not appear to be the result of a hormone imbalance. These normal, cyclical hormone changes cause chemical changes in the brain, and many experts believe that PMS and PMDD result from sensitivities to these changes. For example, studies have found that people who experience PMS or PMDD symptoms often have a notable drop in serotonin levels during the premenstrual period.
